High availability in Docker Swarm
Estimated reading time: 5 minutesYou are viewing docs for legacy standalone Swarm. These topics describe standalone Docker Swarm. In Docker 1.12 and higher, Swarm mode is integrated with Docker Engine. Most users should use integrated Swarm mode — a good place to start is Getting started with swarm mode, Swarm mode CLI commands, and the Get started with Docker walkthrough). Standalone Docker Swarm is not integrated into the Docker Engine API and CLI commands.
In Docker Swarm, the swarm manager is responsible for the entire cluster and manages the resources of multiple Docker hosts at scale. If the swarm manager dies, you must create a new one and deal with an interruption of service.
The High Availability feature allows a swarm to gracefully handle the failover of a manager instance. Using this feature, you can create a single primary manager instance and multiple replica instances.
A primary manager is the main point of contact with the swarm cluster. You can also create and talk to replica instances that act as backups. Requests issued on a replica are automatically proxied to the primary manager. If the primary manager fails, a replica takes away the lead. In this way, you always keep a point of contact with the cluster.
Setup primary and replicas
This section explains how to set up Docker Swarm using multiple managers.
Assumptions
You need either a Consul
, etcd
, or Zookeeper
cluster. This procedure is written assuming a Consul
server running on address <IP_ADDRESS>:8500
. All hosts have a Docker Engine configured to listen on port 2375. The Managers operate on port 4000. The sample swarm configuration has three machines:
manager-1
on<IP_ADDRESS>
manager-2
on<IP_ADDRESS>
manager-3
on<IP_ADDRESS>
Create the primary manager
You use the swarm manage
command with the --replication
and --advertise
flags to create a primary manager.
user@manager-1 $ swarm manage -H :4000 <tls-config-flags> --replication --advertise <IP_ADDRESS>:4000 consul://<IP_ADDRESS>:8500/nodes
INFO[0000] Listening for HTTP addr=:4000 proto=tcp
INFO[0000] Cluster leadership acquired
INFO[0000] New leader elected: <IP_ADDRESS>:4000
[...]
The --replication
flag tells Swarm that the manager is part of a multi-manager configuration and that this primary manager competes with other manager instances for the primary role. The primary manager has the authority to manage cluster, replicate logs, and replicate events happening inside the cluster.
The --advertise
option specifies the primary manager address. Swarm uses this address to advertise to the cluster when the node is elected as the primary. As you see in the command’s output, the address you provided now appears to be the one of the elected Primary manager.
Create two replicas
Now that you have a primary manager, you can create replicas.
user@manager-2 $ swarm manage -H :4000 <tls-config-flags> --replication --advertise <IP_ADDRESS>:4000 consul://<IP_ADDRESS>:8500/nodes
INFO[0000] Listening for HTTP addr=:4000 proto=tcp
INFO[0000] Cluster leadership lost
INFO[0000] New leader elected: <IP_ADDRESS>:4000
[...]
This command creates a replica manager on <IP_ADDRESS>:4000
which is looking at <IP_ADDRESS>:4000
as the primary manager.
Create an additional, third manager instance:
user@manager-3 $ swarm manage -H :4000 <tls-config-flags> --replication --advertise <IP_ADDRESS>:4000 consul://<IP_ADDRESS>:8500/nodes
INFO[0000] Listening for HTTP addr=:4000 proto=tcp
INFO[0000] Cluster leadership lost
INFO[0000] New leader elected: <IP_ADDRESS>:4000
[...]
Once you have established your primary manager and the replicas, create swarm agents as you normally would.
List machines in the cluster
Typing docker info
should give you an output similar to the following:
user@my-machine $ export DOCKER_HOST=<IP_ADDRESS>:4000 # Points to manager-1
user@my-machine $ docker info

This information shows that manager-1
is the current primary and supplies the address to use to contact this primary.
Test the failover mechanism
To test the failover mechanism, you shut down the designated primary manager.
Issue a Ctrl-C
or kill
the current primary manager (manager-1
) to shut it down.
Wait for automated failover
After a short time, the other instances detect the failure and a replica takes the lead to become the primary manager.
For example, look at manager-2
’s logs:
user@manager-2 $ swarm manage -H :4000 <tls-config-flags> --replication --advertise <IP_ADDRESS>:4000 consul://<IP_ADDRESS>:8500/nodes
INFO[0000] Listening for HTTP addr=:4000 proto=tcp
INFO[0000] Cluster leadership lost
INFO[0000] New leader elected: <IP_ADDRESS>:4000
INFO[0038] New leader elected: <IP_ADDRESS>:4000
INFO[0038] Cluster leadership acquired <--- We have been elected as the new Primary Manager
[...]
Because the primary manager, manager-1
, failed right after it was elected, the replica with the address <IP_ADDRESS>:4000
, manager-2
, recognized the failure and attempted to take away the lead. Because manager-2
was fast enough, the process was effectively elected as the primary manager. As a result, manager-2
became the primary manager of the cluster.
If we take a look at manager-3
we should see those logs
:
user@manager-3 $ swarm manage -H :4000 <tls-config-flags> --replication --advertise <IP_ADDRESS>:4000 consul://<IP_ADDRESS>:8500/nodes
INFO[0000] Listening for HTTP addr=:4000 proto=tcp
INFO[0000] Cluster leadership lost
INFO[0000] New leader elected: <IP_ADDRESS>:4000
INFO[0036] New leader elected: <IP_ADDRESS>:4000 <--- manager-2 sees the new Primary Manager
[...]
At this point, we need to export the new DOCKER_HOST
value.
Switch the primary
To switch the DOCKER_HOST
to use manager-2
as the primary, you do the following:
user@my-machine $ export DOCKER_HOST=<IP_ADDRESS>:4000 # Points to manager-2
user@my-machine $ docker info
Containers: 0
Images: 25
Storage Driver:
Role: Primary <--------- manager-2 is the Primary manager
Primary: <IP_ADDRESS>
Strategy: spread
Filters: affinity, health, constraint, port, dependency
Nodes: 3
You can use the docker
command on any swarm manager or any replica.
If you like, you can use custom mechanisms to always point DOCKER_HOST
to the current primary manager. Then, you never lose contact with your swarm in the event of a failover.

The intent of this library is to implement the unordered containers in the draft standard, so the interface was fixed. But there are still some implementation decisions to make. The priorities are conformance to the standard and portability.
The wikipedia article on hash tables has a good summary of the implementation issues for hash tables in general.
By specifying an interface for accessing the buckets of the container the standard pretty much requires that the hash table uses chained addressing.
It would be conceivable to write a hash table that uses another method. For example, it could use open addressing, and use the lookup chain to act as a bucket but there are a some serious problems with this:
So chained addressing is used.
For containers with unique keys I store the buckets in a single-linked list. There are other possible data structures (such as a double-linked list) that allow for some operations to be faster (such as erasing and iteration) but the possible gain seems small compared to the extra memory needed. The most commonly used operations (insertion and lookup) would not be improved at all.
But for containers with equivalent keys a single-linked list can degrade badly
when a large number of elements with equivalent keys are inserted. I think
it's reasonable to assume that users who choose to use unordered_multiset
or unordered_multimap
do so
because they are likely to insert elements with equivalent keys. So I have
used an alternative data structure that doesn't degrade, at the expense of
an extra pointer per node.
This works by adding storing a circular linked list for each group of equivalent nodes in reverse order. This allows quick navigation to the end of a group (since the first element points to the last) and can be quickly updated when elements are inserted or erased. The main disadvantage of this approach is some hairy code for erasing elements.
There are two popular methods for choosing the number of buckets in a hash table. One is to have a prime number of buckets, another is to use a power of 2.
Using a prime number of buckets, and choosing a bucket by using the modulus of the hash function's result will usually give a good result. The downside is that the required modulus operation is fairly expensive.
Using a power of 2 allows for much quicker selection of the bucket to use, but at the expense of loosing the upper bits of the hash value. For some specially designed hash functions it is possible to do this and still get a good result but as the containers can take arbitrary hash functions this can't be relied on.
To avoid this a transformation could be applied to the hash function, for an example see Thomas Wang's article on integer hash functions. Unfortunately, a transformation like Wang's requires knowledge of the number of bits in the hash value, so it isn't portable enough. This leaves more expensive methods, such as Knuth's Multiplicative Method (mentioned in Wang's article). These don't tend to work as well as taking the modulus of a prime, and the extra computation required might negate efficiency advantage of power of 2 hash tables.
So, this implementation uses a prime number for the hash table size.
operator==
and operator!=
are not included in the standard, but I've added them as I think they could
be useful and can be implemented fairly efficiently. They are specified differently
to the other standard containers, comparing keys using the equality predicate
rather than operator==
.
It's also different to the proposal n2944.
which uses the equality operators for the whole of value_type
.
This implementation just uses the key equality function for the key, and mapped_type
's equality operator in unordered_map
and unordered_multimap
for the mapped part of the element.
Also, in unordered_multimap
,
the mapped values for a group of elements with equivalent keys are only considered
equal if they are in the same order, in n2944 they just need to be a permutation
of each other. Since the order of elements with equal keys is now defined to
be stable, it seems to me that their order can be considered part of the container's
value.
Recent drafts have included an overhaul of the allocators, but this was dependent on concepts which are no longer in the standard. n2946 attempts to respecify them without concepts. I'll try to implement this (or an appropriate later version) in a future version of boost, possibly changed a little to accomodate non-C++0x compilers.
It isn't clear how to swap containers when their allocators aren't equal. This is Issue 431: Swapping containers with unequal allocators. This has been resolved with the new allocator specification, so this should be fixed when support is added.
It wan't specified if unordered_multiset
and unordered_multimap
preserve
the order of elements with equivalent keys (i.e. if they're stable under insert
and erase
).
Since n2691
it's been specified that they do and this implementation follows that.

That is the leading question on your mind right now right? Well, I am Joshua Bernard Morr. Currently, I am a developer in the making going through the coding bootcamp at the Portland Tech Academy. I am just a kid trying out new things and trying to develop new skills.
As of right now, I can do absolutely nothing at all. I have zero skills in the field and I am like a baby just learning to crawl. I have a beginning grasp on Version control, HTML5, CSS3, and Bootstrap. Am I confident in my abilities with any of these? Absolutely not. Not yet at least, In the comming months I will become skilled in these and more.
If my lack of skills intrigue you, feel free to shoot me an email. I really don't care. Go for it bud.

by James Rodger, https://www.facebook.com/jamesrodgerjournalistSky Sports presenter Hayley McQueen has been pictured embracing her post-baby body.
The 39-year-old took to social media to share a picture four weeks after giving birth to her first child.
McQueen, a Sky Sports News presenter well-known among sporting fans, gave birth nearly a month ago.
The TV personality gave birth by C-section and recently took to social media to share two pictures with her 176,000 followers.
It came weeks after she and her partner Kirk Newmann recently welcomed their daughter Ayla into the world.
She wrote: "Once upon a time I’d have been terrified about stretch marks & excessive weight gain.
"But the only weight I’ve cared about for the last 10 months has been the healthy weight of my unborn baby.
"I’ve had a couple of negative comments on here from people about this very topic so here I am to address that.
"It’s taken 39 years for me to post a picture in underwear, I’m at my heaviest but also at my absolute happiest.
"I can contently look in the mirror at my puffy belly, the overhang above my stitches, stretch marks & scars & feel so proud of what my body has given me."
McQueen added: "My Instagram paints a picture of newborn bliss.
"Yes Ayla is an angel & a very easy baby thankfully but in reality C section recovery is tough.
"I was in a world of pain the 1st week, didn’t leave my bedroom for 6 days, just walking to the toilet knocked me breathless.
"Don’t even talk to me about looking at the stitches or the splitting & pulling from previous surgery.
"The MRSA meant I had to shower with hospital scrub & wash my hair every single day!

"Oh & my nipples are still raw. Even 4 weeks on I’ve had sudden heavy bleeding so bad it’s knocked me sick."
