| const std::string & | name, | ||
| const dds::core::Duration & | timeout = dds::core::Duration::infinite() |
||
| ) |
This operation gives access to an specific existing (or ready to exist) enabled Topic, ContentFilteredTopic, MultiTopic, AnyTopic or TopicDescription based on its topic_name.
Topics that the application has indicated should be 'ignored' (by means of the dds::topic::ignore operation) will not appear in this list (note: the ignore feature is not yet supported).
If a Topic of the same topic_name already exists, it gives access to this Topic. Otherwise it waits (blocks the caller) until another mechanism creates it. This other mechanism can be another thread, a configuration tool, or some other Data Distribution Service utility. If after the specified timeout the Topic can still not be found, the caller gets unblocked and the returned Topic will be dds::core::null.
A Topic that is obtained by means of find_topic in a specific DomainParticipant can only be used to create DataReaders and DataWriters in that DomainParticipant.
This operation usually results in network look-ups.
For finding only locally created Topics, look here.
| dp | the DomainParticipant |
| name | the topic name to discover |
| timeout | the time out |
| dds::core::Error | An internal error has occurred. |
| dds::core::NullReferenceError | The DomainParticipant was not properly created and references to dds::core::null. |
| dds::core::AlreadyClosedError | The DomainParticipant has already been closed. |
| dds::core::NotEnabledError | The DomainParticipant has not yet been enabled. |
| dds::core::OutOfResourcesError | The Data Distribution Service ran out of resources to complete this operation. |
| dds::core::TimeoutError | No Topics of the given name found within the timeout. |
| uint32_t dds::topic::discover | ( | const dds::domain::DomainParticipant & | dp, |
| FwdIterator | begin, | ||
| uint32_t | max_size | ||
| ) |
This operation retrieves a list of Topics that have been discovered in the domain.
If the max_size of the given list is large enough, all discovered Topics will be present in that list. Otherwise, a random sub-set of max_size elements is returned.
Topics that the application has indicated should be 'ignored' (by means of the dds::topic::ignore operation) will not appear in this list (note: the ignore feature is not yet supported).
Because Topics of various different kinds can be retrieved, the list contains AnyTopics.
This operation usually results in network look-ups.
| dp | the DomainParticipant |
| begin | a forward iterator pointing to the beginning of a container in which to insert the topics |
| max_size | the maximum number of topics to return |
| uint32_t dds::topic::discover_all | ( | const dds::domain::DomainParticipant & | dp, |
| BinIterator | begin | ||
| ) |
This operation retrieves a list of all Topics that have been discovered in the domain.
Topics that the application has indicated should be 'ignored' (by means of the dds::topic::ignore operation) will not appear in this list (note: the ignore feature is not yet supported).
Because Topics of various different kinds can be retrieved, the list contains AnyTopics.
This operation usually results in network look-ups.
| dp | the DomainParticipant |
| begin | a back inserting iterator pointing to the beginning of a container in which to insert the topics |
| TOPIC dds::topic::find | ( | const dds::domain::DomainParticipant & | dp, |
| const std::string & | topic_name | ||
| ) |
This operation gives access to a locally-created Topic, ContentFilteredTopic, MultiTopic, AnyTopic and TopicDescription with a matching name.
dds::topic::find will never create a Topic but returns a reference to an Topic proxy that already exists locally. When no local proxy exists, the returned Topic will be a dds::core::null object. The operation never blocks.
For discovering globally available Topics, look here.
| dp | the DomainParticipant to find the topic on |
| topic_name | the topic name to find |
| void dds::topic::ignore | ( | const dds::domain::DomainParticipant & | dp, |
| const dds::core::InstanceHandle & | handle | ||
| ) |
This operation allows an application to instruct the Service to locally ignore a remote domain participant. From that point onwards the Service will locally behave as if the remote participant did not exist. This means it will ignore any Topic, publication, or subscription that originates on that domain participant.
This operation is not yet implemented. It is scheduled for a future release.
| dp | the DomainParticipant |
| handle | the handle of the DomainParticipant to ignore |
| void dds::topic::ignore | ( | const dds::domain::DomainParticipant & | dp, |
| FwdIterator | begin, | ||
| FwdIterator | end | ||
| ) |
This operation allows an application to instruct the Service to locally ignore a remote domain participant. From that point onwards the Service will locally behave as if the remote participant did not exist. This means it will ignore any Topic, publication, or subscription that originates on that domain participant.
This operation is not yet implemented. It is scheduled for a future release.
| dp | the DomainParticipant |
| begin | a forward iterator pointing to the beginning of a sequence of InstanceHandles to ignore |
| end | a forward iterator pointing to the end of a sequence of InstanceHandles to ignore |

This filter first instruments the page to discover which CSS selectors
will be used by the browser. It uses instrumentation results to select
the critical CSS rules from the page and inlines those in <style>
tags at the top of the document. It lazily loads the original CSS
<style> and <link> tags after the page has loaded.
When you load this page, you may see one of several things:
- An unoptimized, uninstrumented page if pagespeed is still loading
and processing the CSS resources on the page.
- An unoptimized page with instrumentation code at the bottom, once
pagespeed has obtained all the CSS resources the page contains.
- A page with the critical CSS in <style> tags at the top of the
document. The original CSS will be in a <noscript> block at the
bottom of the page, followed by a script that makes them visible to the
browser. This page might also contain additional instrumentation code
to ensure that the critical CSS is still valid.
If you see a flash of unstyled content as the page is loading, it is
possible the beacon results that pagespeed collected did not include rules

The Republic of Palau is committed to the successful conclusion of negotiations under the Ad‐Hoc Working Group on the Durban Platform for Enhanced Action (ADP) in order to adopt, at COP21, a new legally‐binding agreement under the United Nations Framework Convention on Climate Change (UNFCCC) applicable to all Parties, to come into effect in 2020.
In accordance with decisions 1/CP.19 and 1/CP.20, the Republic of Palau is pleased to communicate its Intended Nationally Determined Contribution (INDC) towards achieving the objective of the UNFCCC, as well as accompanying information to facilitate clarity, transparency, and understanding of its INDC.
The Republic of Palau is also pleased to provide additional accompanying information on our mitigation effort and support for implementation.
| Timeframe | Start year: 2020 | End year:2025 |
| Type of commitment | Absolute energy sector emissions reduction target, with additional reductions coming from the waste and transport sectors. |
| Reference/base year | Reference/base year is 2005 - emissions were approximated at 88 thousand tCO2e |
| Estimated quantified emissions reductions | Indicative targets:
|
| Coverage | Energy (electricity generation), transport and waste sectors Gases: Carbon dioxide (CO2 ) and methane (CH4) |
| Baseline assumption | Business as Usual (BAU) emissions scenario projections are based on economic growth in the absence of new climate change policies and measures in addition to those in place in 2015, and greater coverage and implementation of existing measures. BAU projections include the electricity sector only, which is Palau’s largest emitting sector. BAU assumptions include a GDP per capita growth of 3.72% per year (historical 15 year CAGR) and EIA oil price projections in reference case as the basis for residential, government and commercial sector energy use growth projections. Commercial energy use growth projections also took into consideration energy use by private generators in the tourism sector. Emission from the waste management and transport sectors are not included in the BAU projection however emission reduction initiatives will be addressed on a project basis. |
| Intention to use market-based mechanisms to meet target | No |
| Land sector accounting approach | N/A |
| Planning Process | Palau’s INDC is grounded in the Palau Climate Change Policy, which was informed by input from communities, civil society and other stakeholders, as well as on the preparatory work for Palau’s second National Communication which was also widely consulted. The Policy establishes Palau’s National Appropriate Mitigation Actions (NAMA) and National Adaptation Plan (NAP) as well as the institutional and policy frameworks for: (a) climate change mitigation via management of greenhouse gas emissions including carbon sinks; and (b) climate change adaptation and risk reduction and management. It establishes the policy framework that will guide and inform action in accordance with Palau’s National Master Development Plan - Palau 2020. |
| Fair and Ambitious | The Republic of Palau’s total emissions are de minimis in the global context. Given Palau’s remoteness, the small size of the economy, low GDP per capita, dependence on partnership support and vulnerability to climate change, Palau’s proposed targets are ambitious and fair as measured against other nations. Under the BAU scenario emissions would be 140 thousand tCO2e in 2025, compared to 68 thousand tCO2e if both the renewable energy and energy efficiency targets are met. Emissions in 2005 were approximated at 88 thousand tCO2e. Full implementation of the renewable energy and energy efficiency strategies outlined below puts Palau on a trajectory to reducing emissions by half as against BAU in 2025, the equivalent of 22% under 2005 emissions levels. |
Business-As Usual emissions projection against INDC full implementation emissions projection (and Renewable Energy and Energy Efficiency scenarios disaggregated)
Palau is joining the community of nations, both industrialised and developing, in taking action to address the causes and impacts of climate change. Palau is particularly vulnerable to the impacts of climate change, principally from sea level rise and the increase in extreme events (drought, flooding, Category 4 and 5 typhoons). Sea-level rise threatens vital infrastructure, settlements, and facilities that support the livelihood of island communities. Moreover, under most climate change scenarios, water resources in small islands are likely to be seriously compromised. Subsistence and commercial agriculture will be adversely affected by climate change, and ocean warming and acidification will heavily impact coral reefs, fisheries, and other marine-based resources crucial to our livelihoods, economy and culture.
i. Current Policies and Measures
Currently Palau is working to increase the share of renewables in our energy mix and to increase energy efficiency initiatives. To date, total renewable energy efforts have only reached 8% of the needed 22%, principally because two grid-connected solar projects (1.5 and 3.5MW respectively) never came to fruition. However to date Palau has achieved an approximately 30% reduction in energy use due to efficiency measures taken.
Current renewable energy and energy efficiency policies and measures include: a pilot loan subsidy for solar roof panels which will be increased to cover more homes if successful; a Home Energy Efficiency Program at the Palau National Development Bank; prepaid metering at Palau Public Utilities Corporation; distribution of CFL light bulbs; government building retrofits; and, a pilot Energy Audit program for large commercial buildings.
ii. Future Policies and Measures to achieve INDC target
To achieve the renewable energy target Palau will need considerable additional installed capacity, including the 5MW of solar already planned (two or more solar projects plus additional roof-top solar) plus an additional 10 MW to power the water sector. Palau will also have to work to reduce transmission and distribution losses. (Solar Capacity Factor is assumed to be 15.3%.)
To implement the Energy Efficiency target, Palau will:
Many of these renewable energy and energy efficiency initiatives will depend on the availability of partnership finance and technology support.
i. Additional project based initiatives in the transport and waste sectors
Reducing Methane Emissions from the Solid Waste Sector
Transport Sector
Climate change presents a major challenge for Palau’s sustainable development, for which the nation relies significantly on development partnerships. Similarly, as noted above, implementation of many of the policies and measures needed to achieve our emissions reduction target will depend on the availability of partnership finance, technology support and capacity development.
Based on a first‐order estimate, the upfront investment cost for the renewable energy and energy efficiency measures in Palau’s INDC would be on the order of $5.5 million USD. This investment has the potential to generate savings, on a net-present-value basis, of $2.5 million by 2025. This figure doesn’t show the full picture of potential returns on investment though, as there was not sufficient data to assess the energy efficiency savings which have the potential to be substantial.

2020 donation to Darien Wilson for Douglas County Commissioner
Delegate to HRCA (Highlands Ranch Community Association) Network of Executive Women
Recently chaired the Sponsorship Committee for the Network of Executive Women. Currently serve as a delegate to the HRCA (Highlands Ranch Community Association). Some duties and powers of the Delegate body include amending and approving the community Bylaws, creating rules and regulations for the use and operation of the recreational facilities, proposing increases and/or reductions for the Recreation Function Common Assessments (RFCA’s) necessary for the operation of the Recreation Center and proposing and reviewing improvements to the recreational facilities. Previously I've served on the Parks & Rec Commission and Liquor Licensing Board in Glenwood Springs. Also served as a volunteer for the Advocate Safehouse Project, a non-profit agency that provides support for survivors of domestic &/or sexual violence, through advocacy, education, support, and safe housing in Garfield County, CO.
I’d like to serve on the commission to contribute to the fair and sensible redrawing of non-politically motivated districts that adapt to Colorado’s dynamic population and growth.
Achieving consensus is about making sure all stakeholder voices are heard. The primary reason people disagree is that they have not clearly heard the other’s alternative and reasons for supporting it. It is important to identify the areas of agreement, identify alternatives where there is disagreement, discuss the strengths and weaknesses, and merge the alternatives. The process might involve building criteria lists and scoring alternatives. Then the group can converge upon an alternative. Once criteria for scoring is agreed upon it makes for a more impartial application of criteria on the data set to achieve more fair districts. I cannot overstate how personalities come into play and that is important that everyone feels heard and to create an environment that allows individuals to save face.
My professional life involves lots of data analysis in the sales and marketing of consumer packaged goods. Applying logic and reason on the independent redistricting commission will require teamwork, negotiation and compromise with the ultimate goal of achieving a fair outcome. Analysis, logic and reason is only part of the equation. Managing people/relationships and making each team member feel valued is the secret sauce that helps all the pieces fit together. Each individual on the commission is important. I am skilled at making people feel valued.

Religious leaders urged to be ambassadors/agents of Road Safety
by Victoria Agyemang, GNACape Coast, Nov.17, GNA - The National Road Safety Authority (NRSA) has called on religious leaders to be agents of road safety in their respective places of worship to reduce accidents.
Religious leaders including pastors, imams and traditional authorities have critical roles to play to ensure safety on the roads, it said.
Mr Victor Kojo Bilson, the Acting Regional Head of NRSC, made the call when the Authority educated leaders and members of the Cape Coast branch of the International Central Gospel Church (ICGC) on Sunday.
It forms part of activities to mark the World Remembrance Day for Road Traffic Victims on the theme: "Life is not a car Part" to intensify the sensitisation drive on Road Safety.
Mr Bilson, who took the congregation through some road and traffic signs, symbols and regulations, stated that all road users must adhere to the rules.
He said religious leaders must use their influence to preach safety and educate their members on the importance of complying with road safety regulations.
He said human errors such as carelessness, overloading, disregard for safety regulations, excessive speeding and drink driving were major causes of road crashes in the Region leading to loss of lives.
The situation should be tackled collectively to prevent the possibility of losing more breadwinners and energetic human resources, he said, and advised the congregation to employ defensive driving techniques.
He urged motor riders to use their crash helmets always to avoid fatalities whenever there was an accident.
Reverend Reuben Kwabla Obeng, the Head Pastor, commended the Authority for extending the educational campaign to the church and encouraged the congregation to apply the knowledge acquired to help reduce road crashes.

String methods help you to work with strings.
The indexOf() method returns the index of (the position of) the first occurrence of a specified text in a string:
The lastIndexOf() method returns the index of the last occurrence of a specified text in a string:
Both the indexOf(), and the lastIndexOf() methods return -1 if the text is not found.
|
JavaScript counts positions from zero. 0 is the first position in a string, 1 is the second, 2 is the third ... |
Both methods accept a second parameter as the starting position for the search.
The search() method searches a string for a specified value and returns the position of the match:
Did You Notice? |
The two methods, indexOf() and search(), are equal.
They accept the same arguments (parameters), and they return the same value.
The two methods are equal, but the search() method can take much more powerful search values.
You will learn more about powerful search values in the chapter about regular expressions.
There are 3 methods for extracting a part of a string:
slice() extracts a part of a string and returns the extracted part in a new string.
The method takes 2 parameters: the starting index (position), and the ending index (position).
This example slices out a portion of a string from position 7 to position 13:
The result of res will be:
If a parameter is negative, the position is counted from the end of the string.
This example slices out a portion of a string from position -12 to position -6:
The result of res will be:
If you omit the second parameter, the method will slice out the rest of the string:
or, counting from the end:
| Negative positions does not work in Internet Explorer 8 and earlier. |
substring() is similar to slice().
The difference is that substring() cannot accept negative indexes.
The result of res will be:
If you omit the second parameter, substring() will slice out the rest of the string.
substr() is similar to slice().
The difference is that the second parameter specifies the length of the extracted part.
The result of res will be:
If the first parameter is negative, the position counts from the end of the string.
The second parameter can not be negative, because it defines the length.
If you omit the second parameter, substr() will slice out the rest of the string.
The replace() method replaces a specified value with another value in a string:
The replace() method can also take a regular expression as the search value.
A string is converted to upper case with toUpperCase():
A string is converted to lower case with toLowerCase():
concat() joins two or more strings:
The concat() method can be used instead of the plus operator. These two lines do the same:
|
All string methods return a new string. They don't modify the original string. Formally said: Strings are immutable: Strings cannot be changed, only replaced. |
There are 2 safe methods for extracting string characters:
The charAt() method returns the character at a specified index (position) in a string:
The charCodeAt() method returns the unicode of the character at a specified index in a string:
You might have seen code like this, accessing a string as an array:
This is unsafe and unpredictable:
If you want to read a string as an array, convert it to an array first.
A string can be converted to an array with the split() method:
If the separator is omitted, the returned array will contain the whole string in index [0].
If the separator is "", the returned array will be an array of single characters:

businessSeller
If true, this indicates that the seller is a business user
property
and intends to use listing features that are offered to
business users only. Applicable only to business sellers
residing in Germany, Austria, or Switzerland who are listing in
a B2B VAT- enabled category on the eBay Germany (DE), Austria
(AT), or Switzerland (CH) sites. The seller must have a valid
VAT ID registered with eBay. This must be set to true if
RestrictedToBusiness is true. It has no effect (and it’s not returned)
if RestrictedToBusiness is false. If an item was not qualified as a
business item when originally listed, but meets the conditions for
business items when the item is revised or relisted, the seller can
convert the item to a business item by specifying the appropriate
VAT details. See the eBay Web Services guide for more information and additional rules. -
restrictedToBusiness
If true, this indicates that the seller elects to offer the
property
item exclusively to business users. If false (or not returned),
this indicates that the seller elects to offer the item to all users.
Applicable only to business sellers residing in Germany,
Austria, or Switzerland who are listing in a B2B VAT-enabled
category on the eBay Germany (DE), Austria (AT), or Switzerland
(CH) sites. If this argument is true, the seller must have a
valid VAT-ID registered with eBay, and BusinessSeller must also
be true. -
vatPercent
VAT rate for the item, if any. When the VATPercent is specified, the
property
item’s VAT information appears on the item’s listing page. In
addition, the seller can choose to print an invoice that
includes the item’s net price, VAT percent, VAT amount, and
total price. Since VAT rates vary
depending on the item and on the user’s country of residence, a
seller is responsible for entering the correct VAT rate; it is
not calculated by eBay. To specify a VATPercent, a seller must
have a VAT-ID registered with eBay and must be listing the item on a
VAT-enabled site. Max applicable length is 6 characters,
including the decimal (e.g., 12.345). The scale is 3 decimal places.
(If you pass in 12.3456, eBay may round up the value to 12.346.)
Note: The View Item page may display the precision to 2 decimal places
with no trailing zeros. However, the full value you send in is stored. -

THE GINGERBREAD MAN 1998 A film review by Timothy Voon Copyright 1998 Timothy Voon 3 :-( :-( :-( for Grisham's worst told tale yet
Cast: Kenneth Branagh, Embeth Davidtz, Robert Downey Jr., Daryl Hannah, Robert Duvall, Tom Berenger, Famke Janssen, Jesse James, Mae Whitman Director: Robert Altman Producer: Jeremy Tannenbaum Screenplay: "Al Hayes" (Robert Altman) based on an original story by John Grisham
The first thing that struck me about this movie, was how amateurish it felt. Maybe, this was the intent of the usually brilliant Robert Altman, who I am surprised decided to cash in on this potentially commercial, John Grisham product. Well, why not, if Ford Coppola saw fit to direct THE RAINMAKER?
This isn't your standard Grisham courtroom drama. Gone are the usual features of the incredibly corrupt industrial forces vs. the severely disadvantaged individual, with a lawyer carrying a conscience thrown somewhere in between. Also gone, are some strong Grisham's tendencies to highlight moralistic issues.
Sadly so, because this movie has ended up becoming melodramatic trash, more in consistency with Sidney Sheldon or Jackie Collins, but lacking the bitchy edge. What we have is a sleazy lawyer (Kenneth Branagh), who ends up in bed with a mysterious waitress (Embeth Davidzt), living in fear of her lunatic father (Robert Duvall). The movie hits an all time low, when a mostly grumpy, whiney Branagh loses all self control when his kids get kidnap. I guess there is a moral here, somewhere, if you sleep around expect to get more than just you're fair share of STD's.
As already mentioned, Branagh is painful to watch when not reciting Shakespeare. Daryl Hannah acts as an assistant lawyer, but it takes more than her pair of glasses to make her role intelligent. Robert Downey Jr, is once again stoned, etc. Duvall is genuinely crazed, whilst Davidzt mopes, and Tom Berenger has very little screen time.
A most disappointing tale, with little relevance to the children's story on which it is based, except for the fact that Davidzt got nightmares when Duval told her the story when she was a kid.

Tokyo floated one-month time frame for retracting export curbs ahead of GSOMIA deal with Seoul: report
Japan floated a specific time frame to withdraw its tightened export controls against South Korea, an offer that apparently spurred Seoul’s decision to remain in a key intelligence-sharing pact, according to the Yonhap news agency.
Japan said it would take about a month to retract the trade curbs after making sure there is no problem with South Korea’s export management, the news agency reported Monday, citing unspecified sources.
Seoul announced on Friday it was staying in the General Security of Military Information Agreement (GSOMIA) just hours before it was to expire.
The flow of events contradicts claims by Japanese officials that Tokyo is not planning to ease its tightened export control measures anytime soon. South Korea’s presidential Blue House and the Japanese government could not immediately be reached for comment.
Meanwhile, Chief Cabinet Secretary Yoshihide Suga denied Monday that Tokyo offered an apology after Seoul accused Japan of deliberately distorting the details of South Korea’s decision to maintain the GSOMIA.
The remark by Suga, Japan’s top government spokesman, came after South Korea said over the weekend that it had lodged a protest through diplomatic channels over Japan’s distortion of the facts and had received an apology.
“It’s unproductive to comment on what the South Korean side says each time. At any rate, it’s not true that the government apologized,” Suga said at a news conference.
On Sunday, Seoul accused Tokyo of misrepresenting South Korea’s position regarding stricter Japanese export controls imposed earlier this year.
But Japan’s trade ministry said it had consulted with South Korea over key points of the export controls before making an announcement.

Woman forced to close on first day after book store flooded with 4 inch deep water
Young entrepreneur Freya King, 22, suffered a loss of £3,400 in her book store business on the first day when she found out her shop was flooded with four inches deep water
by Paige Oldfield, Tiffany LoA woman was forced to close her business on the first day after finding her new shop was ruined by floodwater.
Freya King, 22, prepared months to open a children's book store, Toy Stories, in Matlock, Deryshire, and scheduled for launch on Friday.
Freya, from Chapel-en-le-Frith, told Derbyshire Live she arrived the store in Crown Square to find it around four inches deep in water.
Stock worth of £400 had been ruined and around £3,000 worth of damage had been done to the floor.
She said: "I'm feeling pretty low. It's quite disheartening.
"I'm about four inches deep in water. The floor is going to have to be ripped out again.
"Tractors keep coming through and blasting water through the shops. The sand bags are piled high.
Due to widespread flooding in the area, trains were not able to run between Derby and Matlock and roads within the town remained closed.
Freya said she had no idea when the shop will eventually be able to reopen.
"We've been trying to set it up for two months," she added.
"The water is almost going over our wellies. It's quite bad."
A number of flood warnings are active in Derbyshire this afternoon, including for the River Derwent at Ambaston Lane, Ambergate, Belper, Calver, Chatsworth, Darley Dale, Duffield, Matlock Bath, Raynesway, and Whatstandwell.

Kubernetes Networking
By the end of this exercise, you should be able to:
- Predict what routing tables rules calico will write to each host in your cluster
- Route and load balance traffic to deployments using clusterIP and nodePort services
- Reconfigure a deployment into a daemonSet (analogous to changing scheduling from 'replicated' to 'global' in a swarm service)
Routing Traffic with Calico
Make sure you're on the master node
kube-0
, and redeploy the nginx deployment defined indeployment.yaml
from the last exercise.List your pods:
[centos@kube-0 ~]$ kubectl get pods
Get some metadata on one of the pods found in the last step:
[centos@kube-0 ~]$ kubectl describe pods <pod name>
which in my case results in:
Name: nginx-deployment-69df458bc5-cg4mk Namespace: default Priority: 0 PriorityClassName: <none> Node: kube-1/<IP_ADDRESS> Start Time: Tue, 21 Aug 2018 14:47:48 +0000 Labels: app=nginx pod-template-hash=2589014671 Annotations: <none> Status: Running IP: <IP_ADDRESS> Controlled By: ReplicaSet/nginx-deployment-69df458bc5 Containers: nginx: Container ID: docker://664616eb1f860e3aff3be5b1dd26f41d37b33495fee9db04429e70ab87efbe56 Image: nginx:1.7.9 Image ID: docker-pullable://nginx@sha256:e3456c851a152494c3e4ff5fcc26f240206abac0c9d794affb40e0714846c451 Port: <none> Host Port: <none> State: Running Started: Tue, 21 Aug 2018 14:47:50 +0000 Ready: True Restart Count: 0 Environment: <none> Mounts: /var/run/secrets/kubernetes.io/serviceaccount from default-token-5ggnn (ro) Conditions: Type Status Initialized True Ready True ContainersReady True PodScheduled True Volumes: default-token-5ggnn: Type: Secret (a volume populated by a Secret) SecretName: default-token-5ggnn Optional: false QoS Class: BestEffort Node-Selectors: <none> Tolerations: node.kubernetes.io/not-ready:NoExecute for 300s node.kubernetes.io/unreachable:NoExecute for 300s Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Scheduled 1m default-scheduler Successfully assigned default/nginx-deployment-69df458bc5-cg4mk to kube-1 Normal Pulled 1m kubelet, kube-1 Container image "nginx:1.7.9" already present on machine Normal Created 1m kubelet, kube-1 Created container Normal Started 1m kubelet, kube-1 Started container
We can see that in our case the pod has been deployed to
kube-1
as indicated near the top of the output, and the pod has an IP of<IP_ADDRESS>
.Have a look at the routing table on
kube-0
usingip route
, which for my example looks like:[centos@kube-0 ~]$ ip route default via <IP_ADDRESS> dev eth0 <IP_ADDRESS>/20 dev eth0 proto kernel scope link src <IP_ADDRESS> <IP_ADDRESS>/16 dev docker0 proto kernel scope link src <IP_ADDRESS> <IP_ADDRESS>/26 via <IP_ADDRESS> dev tunl0 proto bird onlink blackhole <IP_ADDRESS>/26 proto bird <IP_ADDRESS> dev cali6edd91665ff scope link <IP_ADDRESS> dev calia9ee759be59 scope link
Notice the fourth line; this rule was written by Calico to send any traffic on the <IP_ADDRESS>/26 subnet (which the pod we examined above is on) to the host at IP <IP_ADDRESS> via IP in IP as indicated by the
dev tunl0
entry. Look at your own routing table and list of VM IPs; what are the corresponding subnets, pod IPs and host IPs in your case? Does that make sense based on the host you found for the nginx pod above?Curl your pod's IP on port 80 from
kube-0
; you should see the HTML for the nginx landing page. By default this pod is reachable at this IP from anywhere in the Kubernetes cluster.Head over to the node this pod got scheduled on (
kube-1
in the example above), and have a look at that host's routing table in the same way:[centos@kube-1 ~]$ ip route default via <IP_ADDRESS> dev eth0 <IP_ADDRESS>/20 dev eth0 proto kernel scope link src <IP_ADDRESS> <IP_ADDRESS>/16 dev docker0 proto kernel scope link src <IP_ADDRESS> blackhole <IP_ADDRESS>/26 proto bird <IP_ADDRESS> dev calib0aa6a43271 scope link <IP_ADDRESS> dev cali3489915b309 scope link <IP_ADDRESS> dev cali2d894f7a3f6 scope link <IP_ADDRESS>/26 via <IP_ADDRESS> dev tunl0 proto bird onlink
Again notice the second-to-last line; this time, the pod IP is routed to a
cali***
device, which is a virtual ethernet endpoint in the host's network namespace, providing a point of ingress into that pod. Once again trycurl <pod IP>:80
- you'll see the nginx landing page html as before.Back on
kube-0
, fetch the logs generated by the pod you've been curling:[centos@kube-0 ~]$ kubectl logs <pod name> <IP_ADDRESS> - - [09/May/2018:13:58:42 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.29.0" "-" <IP_ADDRESS> - - [09/May/2018:14:00:41 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.29.0" "-"
We see records of the curls we preformed above; like Docker containers, these logs are the STDOUT and STDERR of the containerized processes.
Routing and Load Balancing with Services
Above we were able to hit nginx at the pod IP, but there is no guarantee this pod won't get rescheduled to a new IP. If we want a stable IP for this deployment, we need to create a
ClusterIP
service. In a filecluster.yaml
on your masterkube-0
:apiVersion: v1 kind: Service metadata: name: cluster-demo spec: selector: app: nginx ports: - port: 8080 targetPort: 80
Create this service with
kubectl create -f cluster.yaml
. This maps the pod internal port 80 to the cluster wide external port 8080; furthermore, this IP and port will only be reachable from within the cluster. Also note theselector: app: nginx
specification; that indicates that this service will route traffic to every pod that hasnginx
as the value of theapp
label in this namespace.Let's see what services we have now:
[centos@kube-0 ~]$ kubectl get services NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP <IP_ADDRESS> <none> 443/TCP 33m cluster-demo ClusterIP <IP_ADDRESS> <none> 8080/TCP 48s
The second one is the one we just created and we can see that a stable IP address and port
<IP_ADDRESS>:8080
has been assigned to ournginx
service.Let's try to access Nginx now, from any node in our cluster:
[centos@kube-0 ~]$ curl <nginx CLUSTER-IP>:8080
which should return the Nginx welcome page. Even if pods get rescheduled to new IPs, this clusterIP service will preserve a stable entrypoint for traffic to be load balanced across all pods matching the service's label selector.
ClusterIP services are reachable only from within the Kubernetes cluster. If you want to route traffic to your pods from an external network, you'll need a NodePort service. On your master
kube-0
, create a filenodeport.yaml
:apiVersion: v1 kind: Service metadata: name: nodeport-demo spec: type: NodePort selector: app: nginx ports: - port: 8080 targetPort: 80
Create this service with
kubectl create -f nodeport.yaml
. Notice this is exactly the same as the ClusterIP service definition, but now we're requesting a type NodePort.Inspect this service's metadata:
[centos@kube-0 ~]$ kubectl describe service nodeport-demo
Notice the NodePort field: this is a randomly selected port from the range 30000-32767 where your pods will be reachable externally. Try visiting your nginx deployment at any public IP of your cluster, and the port you found above, and confirming you can see the nginx landing page.
Clean up the objects you created in this section:
[centos@kube-0 ~]$ kubectl delete deployment nginx-deployment [centos@kube-0 ~]$ kubectl delete service cluster-demo [centos@kube-0 ~]$ kubectl delete service nodeport-demo
Optional: Deploying DockerCoins onto the Kubernetes Cluster
First deploy Redis via
kubectl create deployment
:[centos@kube-0 ~]$ kubectl create deployment redis --image=redis
And now all the other deployments. To avoid too much typing we do that in a loop:
[centos@kube-0 ~]$ for DEPLOYMENT in hasher rng webui worker; do kubectl create deployment $DEPLOYMENT --image=training/dockercoins-${DEPLOYMENT}:1.0 done
Let's see what we have:
[centos@kube-0 ~]$ kubectl get pods -o wide -w
in my case the result is:
hasher-6c64f78655-rgjk5 1/1 Running 0 53s <IP_ADDRESS> node-2 redis-75586d7d7c-mmjg7 1/1 Running 0 5m <IP_ADDRESS> kube-1 rng-d94d56d4f-twlwz 1/1 Running 0 53s <IP_ADDRESS> kube-1 webui-6d8668984d-sqtt8 1/1 Running 0 52s <IP_ADDRESS> node-2 worker-56756ddbb8-lbv9r 1/1 Running 0 52s <IP_ADDRESS> kube-1
pods have been distributed across our cluster.
We can also look at some logs:
[centos@kube-0 ~]$ kubectl logs deploy/rng [centos@kube-0 ~]$ kubectl logs deploy/worker
The
rng
service (and also thehasher
andwebui
services) seem to work fine but theworker
service reports errors. The reason is that unlike on Swarm, Kubernetes does not automatically provide a stable networking endpoint for deployments. We need to create at least aClusterIP
service for each of our deployments so they can communicate.List your current services:
[centos@kube-0 ~]$ kubectl get services NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP <IP_ADDRESS> <none> 443/TCP 46m
Expose the
redis
,rng
andhasher
internally to your cluster, specifying the correct internal port:[centos@kube-0 ~]$ kubectl expose deployment redis --port 6379 [centos@kube-0 ~]$ kubectl expose deployment rng --port 80 [centos@kube-0 ~]$ kubectl expose deployment hasher --port 80
List your services again:
[centos@kube-0 ~]$ kubectl get services NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE hasher ClusterIP <IP_ADDRESS> <none> 80/TCP 20s kubernetes ClusterIP <IP_ADDRESS> <none> 443/TCP 47m redis ClusterIP <IP_ADDRESS> <none> 6379/TCP 31s rng ClusterIP <IP_ADDRESS> <none> 80/TCP 26s
Evidently
kubectl expose
createsClusterIP
services allowing stable, internal reachability for your deployments, much like you did via yaml manifests for your nginx deployment in the last section. See thekubectl
api docs for more command-line alternatives to yaml manifests.Get the logs of the worker again:
[centos@kube-0 ~]$ kubectl logs deploy/worker
This time you should see that the
worker
recovered (give it at least 10 seconds to do so). Theworker
can now access the other services.Now let's expose the
webui
to the public using a service of typeNodePort
:[centos@kube-0 ~]$ kubectl expose deploy/webui --type=NodePort --port 80
List your services one more time:
[centos@kube-0 ~]$ kubectl get services NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE hasher ClusterIP <IP_ADDRESS> <none> 80/TCP 2m kubernetes ClusterIP <IP_ADDRESS> <none> 443/TCP 49m redis ClusterIP <IP_ADDRESS> <none> 6379/TCP 2m rng ClusterIP <IP_ADDRESS> <none> 80/TCP 2m webui NodePort <IP_ADDRESS> <none> 80:32015/TCP 33s
Notice the
NodePort
service created forwebui
. This type of service provides similar behavior to the Swarm L4 mesh net: a port (32015 in my case) has been reserved across the cluster; any external traffic hitting any cluster IP on that port will be directed to port 80 inside awebui
pod.Visit your Dockercoins web ui at
http://<node IP>:<port>
, where<node IP>
is the public IP address any of your cluster members. You should see the dashboard of our DockerCoins application.Let's scale up the worker a bit and see the effect of it:
[centos@kube-0 ~]$ kubectl scale deploy/worker --replicas=10
Observe the result of this scaling in the browser. We do not really get a 10-fold increase in throughput, just as when we deployed DockerCoins on swarm; the
rng
service is causing a bottleneck.To scale up, we want to run an instance of
rng
on each node of the cluster. For this we use aDaemonSet
. We do this by using a yaml file that captures the desired configuration, rather than through the CLI.Create a file
deploy-rng.yaml
as follows:[centos@kube-0 ~]$ kubectl get deploy/rng -o yaml --export > deploy-rng.yaml
Note:
--export
will remove "cluster-specific" informationEdit this file to make it describe a
DaemonSet
instead of aDeployment
:- change
kind
toDaemonSet
- remove the
replicas
field - remove the
strategy
block (which defines the rollout mechanism for a deployment) - remove the
status: {}
line at the end
- change
Now apply this YAML file to create the
DaemonSet
:[centos@kube-0 ~]$ kubectl apply -f deploy-rng.yaml
We can now look at the
DaemonSet
that was created:[centos@kube-0 ~]$ kubectl get daemonset NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE rng 1 1 1 1 1 <none> 1m
Since we only have one workload-bearing node in our cluster (
kube-1
), we still only get one rng pod and no performance improvement - but, if we added more non-master nodes to our Kubernetes cluster, they would get random number generator pods scheduled on them as they joined, relaxing the bottleneck.If we do a
kubectl get all
we will see that we now have both adeployment.apps/rng
AND adaemonset.apps/rng
. Deployments are not just converted to DaemonSets. Let's delete therng
deployment:[centos@kube-0 ~]$ kubectl delete deploy/rng
Clean up your resources when done:
[centos@kube-0 ~]$ for D in redis hasher rng webui; \ do kubectl delete svc/$D; done [centos@kube-0 ~]$ for D in redis hasher webui worker; \ do kubectl delete deploy/$D; done [centos@kube-0 ~]$ kubectl delete ds/rng
Make sure that everything is cleared:
[centos@kube-0 ~]$ kubectl get all
should only show the
svc/kubernetes
resource.
Conclusion
In this exercise, we looked at some of the key Kubernetes service objects that provide routing and load balancing for collections of pods; clusterIP for internal communication, analogous to Swarm's VIPs, and NodePort, for routing external traffic to an app similarly to Swarm's L4 mesh net. We also briefly touched on the inner workings of Calico, one of many Kubernetes network plugins and the one that ships natively with Docker's Enterprise Edition product. The key networking difference between Swarm and Kubernetes is their approach to default firewalling; while Swarm firewalls software defined networks automatically, all pods can reach all other pods on a Kube cluster, in Calico's case via the BGP-updated control plane and IP-in-IP data plane you explored above.

Sprint-04 Technical Blog
17th September 2020
I had a situation during the Sprint 04 exercise where the code I was working on during the JS Gradebook
task was not behaving as I expected. I believed I had the instructions to the system correct but I kept receiving red errors – meaning my work was not correct.
I tried a variety of different ways to figure out what the problem was. Because I had written out what the task needed to do in what is termed pseudocode
(meaning that there were comments in my code telling me in plain English what success was meant to look like) I was able to think logically about how the code should therefore behave.
Once I had the pseudocode concept clear in my head, I tried a few options in the trail and error
technique to see if I was missing anything obvious. After about half an hour of not being able to work out what the issue was, I took a scheduled break and took Tigre for a walk to try out the rubber ducky method
. This technique of problem solving is using an inanimate object to explain what you expect your code to do (or what you think it does), in the hopes that by saying it out loud in a clear manner the solution to your problem will show itself. Tigre and I had several looong conversations during this Sprint.
During the process I first felt curious about why things where not behaving as I expected them to. After the first couple of attempts at a solution continued to fail, I then moved into the frustrated stage. The pseudocode and the trial and error techniques of problem solving came naturally to me as a tactile learner (I need to get my hands dirty to understand things) so I really enjoyed them.
Speaking to Tigre on the other hand for the first two or three times felt odd as it was not something I had really done before. However since he helped me figure out what the problem was (in one case I jus needed to remove two extra brackets ()
from the code), he has become my constant companion ever since.
Once I found a solution, well that called for a hoopy-dance
(to be demonstarted at a later date on special request).
Through this process I learnt a couple of things.
1. Reading error messages from the console.log is an art form - one I am still finding my zen with.
2. My other new best friend besides Tigre is the console.log()
command. I used this command a lot to help me understand exactly what the code was doing at each step. This helped me track down the issues in record time!
One of things I noticed during the Sprint 04 Kata exercises was generally the first attempt at the solution made my code overly complex, clunky and hard to read. I was really glad I was familiar with the TDD Mantra "red, green, refactor"
I was able to review my code and look for improvements or more elegant options for a given solution. The turning poing came during the stretch exercise during the JS Olympics
task. Due to the work I had completed in the previous katas I was able to see simple and clean solutions to the problems that were being presented. Trusty Google helped in this a lot as well.
During this process I first felt amazing as I could see how the logic fit together and why. It re-iterated to me that while Java might give a programmer clearer and more frequent error messages, JavaScript
ensures that a programmer really has to understand what they are doing and why, otherwise the code is just a black hole and trying to find where your error lies is quite complicated.
Through this process I learnt a couple of things.
1. Google has seen it all before
2. There are many different ways to solve an issue, some of them are not so elegant and others are just plain AwEsOMe
Pseudocode
- As a tactile learner this helps me a lot and I find I use it regularly. It helps keep me focused on the task a hand and helps prevent distraction
Trying something
- Trail and error is also something I gel very naturally with. While it can be frustrating at times, it is a good way for me to use other techniques as well (such as console.logging) to work out where the errors are
Rubber ducky method
- I implement the Tigre solution!
Reading error messages
- Is a real Art form as you can identify the line of the code and the file that is causing an issue. Usually you are able to work out what is causing an error from the message that is being displayed
Console.logging
- Is one of my new best friends!
Googling
- This is a technique that is not only helpful to developers but across many roles. As things are now being digitised more and more, each day introduces new material for people to be able to access. The only catch with this technique is knowing where and how to look for the information as it can become like finding a needle in a haystack
Asking your peers for help
- I have used this to date in Foundations and found talking with other peers very helpful
Asking coaches for help
- This is going to become key as the material becomes more challenging
Improving process with reflection
- Being able to look back helps solidify lessons being learnt. I have also found I revisit items in freeCodeCamp or previous Foundation Sprints where I was not 100% sure on the solution and try the problem again to bed down the knowledge of what was being taught
