MeshConfig
MeshConfig defines mesh-wide variables shared by all Envoy instances in the
Istio service mesh.
NOTE: This configuration type should be used for the low-level global
configuration, such as component addresses and port numbers. It should not
be used for the features of the mesh that can be scoped by service or by
namespace. Some of the fields in the mesh config are going to be deprecated
and replaced with several individual configuration types (for example,
tracing configuration).
| Field |
Type |
Description |
Required |
mixerCheckServer |
string |
Address of the server that will be used by the proxies for policy
check calls. By using different names for mixerCheckServer and
mixerReportServer, it is possible to have one set of Mixer servers handle
policy check calls while another set of Mixer servers handle telemetry
calls.
NOTE: Omitting mixerCheckServer while specifying mixerReportServer is
equivalent to setting disablePolicyChecks to true.
|
No
|
mixerReportServer |
string |
Address of the server that will be used by the proxies for policy report
calls.
|
No
|
disablePolicyChecks |
bool |
Disable policy checks by the Mixer service. Default
is false, i.e. Mixer policy check is enabled by default.
|
No
|
policyCheckFailOpen |
bool |
Allow all traffic in cases when the Mixer policy service cannot be reached.
Default is false which means the traffic is denied when the client is unable
to connect to Mixer.
|
No
|
sidecarToTelemetrySessionAffinity |
bool |
Enable session affinity for Envoy Mixer reports so that calls from a proxy will
always target the same Mixer instance.
|
No
|
proxyListenPort |
int32 |
Port on which Envoy should listen for incoming connections from
other services.
|
No
|
proxyHttpPort |
int32 |
Port on which Envoy should listen for HTTP PROXY requests if set.
|
No
|
connectTimeout |
Duration |
Connection timeout used by Envoy. (MUST BE >=1ms)
|
No
|
protocolDetectionTimeout |
Duration |
Automatic protocol detection uses a set of heuristics to
determine whether the connection is using TLS or not (on the
server side), as well as the application protocol being used
(e.g., http vs tcp). These heuristics rely on the client sending
the first bits of data. For server first protocols like MySQL,
MongoDB, etc., Envoy will timeout on the protocol detection after
the specified period, defaulting to non mTLS plain TCP
traffic. Set this field to tweak the period that Envoy will wait
for the client to send the first bits of data. (MUST BE >=1ms)
|
No
|
tcpKeepalive |
TcpKeepalive |
If set then set SO_KEEPALIVE on the socket to enable TCP Keepalives.
|
No
|
ingressClass |
string |
Class of ingress resources to be processed by Istio ingress
controller. This corresponds to the value of
“kubernetes.io/ingress.class” annotation.
|
No
|
ingressService |
string |
Name of theKubernetes service used for the istio ingress controller.
|
No
|
ingressControllerMode |
IngressControllerMode |
Defines whether to use Istio ingress controller for annotated or all ingress resources.
|
No
|
enableTracing |
bool |
Flag to control generation of trace spans and request IDs.
Requires a trace span collector defined in the proxy configuration.
|
No
|
accessLogFile |
string |
File address for the proxy access log (e.g. /dev/stdout).
Empty value disables access logging.
|
No
|
accessLogFormat |
string |
Format for the proxy access log
Empty value results in proxy’s default access log format
|
No
|
accessLogEncoding |
AccessLogEncoding |
Encoding for the proxy access log (text or json).
Default value is text.
|
No
|
enableEnvoyAccessLogService |
bool |
This flag enables Envoy’s gRPC Access Log Service.
See Access Log Service
for details about Envoy’s gRPC Access Log Service API.
|
No
|
defaultConfig |
ProxyConfig |
Default proxy config used by the proxy injection mechanism operating in the mesh
(e.g. Kubernetes admission controller)
In case of Kubernetes, the proxy config is applied once during the injection process,
and remain constant for the duration of the pod. The rest of the mesh config can be changed
at runtime and config gets distributed dynamically.
|
No
|
outboundTrafficPolicy |
OutboundTrafficPolicy |
Set the default behavior of the sidecar for handling outbound traffic
from the application. If your application uses one or more external
services that are not known apriori, setting the policy to ALLOWANY
will cause the sidecars to route any unknown traffic originating from
the application to its requested destination. Users are strongly
encouraged to use ServiceEntries to explicitly declare any external
dependencies, instead of using allowany, so that traffic to these
services can be monitored.
|
No
|
enableClientSidePolicyCheck |
bool |
Enables client side policy checks.
|
No
|
configSources |
ConfigSource[] |
ConfigSource describes a source of configuration data for networking
rules, and other Istio configuration artifacts. Multiple data sources
can be configured for a single control plane.
|
No
|
enableAutoMtls |
BoolValue |
This flag is used to enable mutual TLS automatically for service to service communication
within the mesh, default false.
If set to true, and a given service does not have a corresponding DestinationRule configured,
or its DestinationRule does not have TLSSettings specified, Istio configures client side
TLS configuration appropriately. More specifically,
If the upstream authentication policy is in STRICT mode, use Istio provisioned certificate
for mutual TLS to connect to upstream.
If upstream service is in plain text mode, use plain text.
If the upstream authentication policy is in PERMISSIVE mode, Istio configures clients to use
mutual TLS when server sides are capable of accepting mutual TLS traffic.
If service DestinationRule exists and has TLSSettings specified, that is always used instead.
|
No
|
trustDomain |
string |
The trust domain corresponds to the trust root of a system.
Refer to SPIFFE-ID
|
No
|
trustDomainAliases |
string[] |
The trust domain aliases represent the aliases of trust_domain .
For example, if we have
trustDomain: td1
trustDomainAliases: ["td2", "td3"]
Any service with the identity td1/ns/foo/sa/a-service-account , td2/ns/foo/sa/a-service-account ,
or td3/ns/foo/sa/a-service-account will be treated the same in the Istio mesh.
|
No
|
defaultServiceExportTo |
string[] |
The default value for the ServiceEntry.export_to field and services
imported through container registry integrations, e.g. this applies to
Kubernetes Service resources. The value is a list of namespace names and
reserved namespace aliases. The allowed namespace aliases are:
- - All Namespaces
. - Current Namespace
~ - No Namespace
If not set the system will use “*” as the default value which implies that
services are exported to all namespaces.
‘All namespaces’ is a reasonable default for implementations that don’t
need to restrict access or visibility of services across namespace
boundaries. If that requirement is present it is generally good practice to
make the default ‘Current namespace’ so that services are only visible
within their own namespaces by default. Operators can then expand the
visibility of services to other namespaces as needed. Use of ‘No Namespace’
is expected to be rare but can have utility for deployments where
dependency management needs to be precise even within the scope of a single
namespace.
For further discussion see the reference documentation for ServiceEntry,
Sidecar, and Gateway.
|
No
|
defaultVirtualServiceExportTo |
string[] |
The default value for the VirtualService.exportto field. Has the same
syntax as ‘defaultserviceexportto’.
If not set the system will use “*” as the default value which implies that
virtual services are exported to all namespaces
|
No
|
defaultDestinationRuleExportTo |
string[] |
The default value for the DestinationRule.exportto field. Has the same
syntax as ‘defaultserviceexportto’.
If not set the system will use “*” as the default value which implies that
destination rules are exported to all namespaces
|
No
|
rootNamespace |
string |
The namespace to treat as the administrative root namespace for
Istio configuration. When processing a leaf namespace Istio will search for
declarations in that namespace first and if none are found it will
search in the root namespace. Any matching declaration found in the root
namespace is processed as if it were declared in the leaf namespace.
The precise semantics of this processing are documented on each resource
type.
|
No
|
localityLbSetting |
LocalityLoadBalancerSetting |
Locality based load balancing distribution or failover settings.
|
No
|
dnsRefreshRate |
Duration |
Configures DNS refresh rate for Envoy clusters of type STRICT_DNS
|
No
|
disableReportBatch |
bool |
The flag to disable report batch.
|
No
|
reportBatchMaxEntries |
uint32 |
When disablereportbatch is false, this value specifies the maximum number
of requests that are batched in report. If left unspecified, the default value
of reportbatchmax_entries == 0 will use the hardcoded defaults of
istio::mixerclient::ReportOptions.
|
No
|
reportBatchMaxTime |
Duration |
When disablereportbatch is false, this value specifies the maximum elapsed
time a batched report will be sent after a user request is processed. If left
unspecified, the default reportbatchmax_time == 0 will use the hardcoded
defaults of istio::mixerclient::ReportOptions.
|
No
|
h2UpgradePolicy |
H2UpgradePolicy |
Specify if http1.1 connections should be upgraded to http2 by default.
if sidecar is installed on all pods in the mesh, then this should be set to UPGRADE.
If one or more services or namespaces do not have sidecar(s), then this should be set to DONOTUPGRADE.
It can be enabled by destination using the destinationRule.trafficPolicy.connectionPool.http.h2UpgradePolicy override.
|
No
|
inboundClusterStatName |
string |
Name to be used while emitting statistics for inbound clusters.
By default, Istio emits statistics with the pattern inbound|<port>|<port-name>|<service-FQDN> .
For example inbound|7443|grpc-reviews|reviews.prod.svc.cluster.local . This can be used to override that pattern.
A Pattern can be composed of various pre-defined variables. The following variables are supported.
%SERVICE% - Will be substituted with name of the service.
%SERVICE_FQDN% - Will be substituted with FQDN of the service.
%SERVICE_PORT% - Will be substituted with port of the service.
%SERVICE_PORT_NAME% - Will be substituted with port name of the service.
Following are some examples of supported patterns for reviews:
%SERVICE_FQDN%_%SERVICE_PORT% will use reviews.prod.svc.cluster.local_7443 as the stats name.
%SERVICE% will use reviews.prod as the stats name.
|
No
|
outboundClusterStatName |
string |
Name to be used while emitting statistics for outbound clusters.
By default, Istio emits statistics with the pattern outbound|<port>|<subsetname>|<service-FQDN> .
For example outbound|8080|v2|reviews.prod.svc.cluster.local . This can be used to override that pattern.
A Pattern can be composed of various pre-defined variables. The following variables are supported.
%SERVICE% - Will be substituted with name of the service.
%SERVICE_FQDN% - Will be substituted with FQDN of the service.
%SERVICE_PORT% - Will be substituted with port of the service.
%SERVICE_PORT_NAME% - Will be substituted with port name of the service.
%SUBSET_NAME% - Will be substituted with subset.
Following are some examples of supported patterns for reviews:
%SERVICE_FQDN%_%SERVICE_PORT% will use reviews.prod.svc.cluster.local_7443 as the stats name.
%SERVICE% will use reviews.prod as the stats name.

Network.NetworkEndpoints
NetworkEndpoints describes how the network associated with an endpoint
should be inferred. An endpoint will be assigned to a network based on
the following rules:
Implicitly: If the registry explicitly provides information about
the network to which the endpoint belongs to. In some cases, its
possible to indicate the network associated with the endpoint by
adding the ISTIO_META_NETWORK
environment variable to the sidecar.
Explicitly:
a. By matching the registry name with one of the “fromRegistry”
in the mesh config. A “from_registry” can only be assigned to a
single network.
b. By matching the IP against one of the CIDR ranges in a mesh
config network. The CIDR ranges must not overlap and be assigned to
a single network.
(2) will override (1) if both are present.
| Field |

|
serviceCluster |
string |
Service cluster defines the name for the service_cluster that is
shared by all Envoy instances. This setting corresponds to
–service-cluster flag in Envoy. In a typical Envoy deployment, the
service-cluster flag is used to identify the caller, for
source-based routing scenarios.
Since Istio does not assign a local service/service version to each
Envoy instance, the name is same for all of them. However, the
source/caller’s identity (e.g., IP address) is encoded in the
–service-node flag when launching Envoy. When the RDS service
receives API calls from Envoy, it uses the value of the service-node
flag to compute routes that are relative to the service instances
located at that IP address.

source IP addresses during redirection.
|
TPROXY |
The TPROXY mode uses iptables TPROXY to redirect to Envoy. This mode preserves both the
source and destination IP addresses and ports, so that they can be used for advanced
filtering and manipulation. This mode also configures the sidecar to run with the
CAPNETADMIN capability, which is required to use TPROXY.

k8s.io.apimachinery.pkg.api.resource.Quantity
Quantity is a fixed-point representation of a number.
It provides convenient marshaling/unmarshaling in JSON and YAML,
in addition to String() and Int64() accessors.
The serialization format is:
::=
(Note that may be empty, from the “” case in .)
::= 0 | 1 | … | 9
::= |
::= | . | . | .
::= “+” | “-”
::= |
::= | |
::= Ki | Mi | Gi | Ti | Pi | Ei
(International System of units; See: http://physics.nist.gov/cuu/Units/binary.html)
::= m | “” | k | M | G | T | P | E
(Note that 1024 = 1Ki but 1000 = 1k; I didn’t choose the capitalization.)
::= “e” | “E”
No matter which of the three exponent forms is used, no quantity may represent
a number greater than 2^63-1 in magnitude, nor may it have more than 3 decimal
places. Numbers larger or more precise will be capped or rounded up.
(E.g.: 0.1m will rounded up to 1m.)
This may be extended in the future if we require larger or smaller quantities.
When a Quantity is parsed from a string, it will remember the type of suffix
it had, and will use the same type again when it is serialized.
Before serializing, Quantity will be put in “canonical form”.
This means that Exponent/suffix will be adjusted up or down (with a
corresponding increase or decrease in Mantissa) such that:
a. No precision is lost
b. No fractional digits will be emitted
c. The exponent (or suffix) is as large as possible.
The sign will be omitted unless the number is negative.
Examples:
1.5 will be serialized as “1500m”
1.5Gi will be serialized as “1536Mi”
Note that the quantity will NEVER be internally represented by a
floating point number. That is the whole point of this exercise.
Non-canonical values will still parse as long as they are well formed,
but will be re-emitted in their canonical form. (So always use canonical
form, or don’t diff.)
This format is intended to make it difficult to use these numbers without
writing some sort of special handling code in the hopes that that will
cause implementors to also use a fixed point implementation.

Crystal Palace 1-2 Liverpool: 5 talking points as Reds edge another tight victory
Liverpool maintained their lead at the top of the table with an eventful victory at Selhurst Park, where second half strikes from Sadio Mane and Roberto Firmino plus a VAR intervention won the day
by Mark Jones, https://www.mirror.co.uk/authors/mark-jones/Liverpool enjoyed another tight victory in their title challenge as two of their forwards plus VAR came to their rescue at Selhurst Park.
The Reds enjoyed a let off when James Tomkins' first half header from a free-kick was disallowed after the VAR judged Jordan Ayew to have fouled Dejan Lovren.
Sadio Mane's strike then put the visitors ahead early in the second half, before Wilfried Zaha looked to have earned Palace a point with a leveller.
However, Roberto Firmino fired home after a corner wasn't cleared to win it with just five minutes remaining.
Here are the game's talking points.
1. The real problem with VAR
In the age of VAR then Ayew should have known better than to raise his hands towards Lovren's back, but the real issue with the technology is just how much time it took to disallow Tomkins' goal.
If you go looking for relatively minor fouls in packed penalty areas then there's a chance you'll find them, and so it proved as Palace were denied an opener that would have been perfectly acceptable in the Premier League last season.
This was harsh on the hosts, and if anything the decision was probably given because Lovren exaggerated his fall, and that can't be right can it?
2. For the Mane not the few
You could say that Mane loves playing against Palace given his excellent record against them (he now has eight goals), but the reality is that the Senegalese loves playing against pretty much everyone right now.
With Mohamed Salah on the sidelines and Firmino out of scoring form before this game, it was again left to Mane to be the man who made the difference with the opener, albeit with the help of a deflection, Vicente Guaita's hand and both posts.
But such is life for Liverpool right now.
3. Lovren proves his place in the pecking order
With the focus on Joe Gomez over the international break as well as Joel Matip getting closer to fitness, this game was a good chance to scrutinise the form of Lovren, who has struggled at Selhurst Park in the past.
He was obviously heavily involved in the incident that led to the disallowed Palace goal, but before that he was probably his side's best player in the first half.
The Croatian has proved his worth as Virgil van Dijk's first-choice partner in recent weeks, and will take some shifting from the side.
4. Ayew sums up Palace's struggles in front of goal
Ayew was the key Palace figure in the first half, and should have given his side the lead when he fired wide.
You can - and probably will - debate about just how much of a push in the back he put in on Lovren for the disallowed goal, but the Ghanaian's display wasn't exactly one of a player who looks like he'll get you goals, and a new striker should be a priority for Palace in the summer.
5. Klopp will have to mix it up next week
Fabinho's second half booking was his fifth of the season, and that might be a blessing in disguise for Liverpool.
After Klopp rested the Brazilian for the win at Villa in order to protect him for the Manchester City game, his most important midfielder will sit out Brighton at home next week through suspension.
You'd think the Reds would win that, giving Klopp a chance to experiment.

This function renders html_document
objects, and returns a string with
the final HTML content. It calls the renderTags
function to
convert any shiny.tag objects to HTML. It also finds any any web dependencies
(created by htmlDependency
) that are attached to the tags, and
inserts those. To do the insertion, this function finds the string
"<!-- HEAD_CONTENT -->"
in the document, and replaces it with the web
dependencies.
