This image is based on oficial RabbitMQ image, but the base image is openshift/base-centos7
.
Pull request to this image can be sended to the ziporah/openshift-rabbitmq
GitHub repo.
RabbitMQ is open source message broker software (sometimes called message-oriented middleware) that implements the Advanced Message Queuing Protocol (AMQP). The RabbitMQ server is written in the Erlang programming language and is built on the Open Telecom Platform framework for clustering and failover. Client libraries to interface with the broker are available for all major programming languages.
One of the important things to note about RabbitMQ is that it stores data based on what it calls the "Node Name", which defaults to the hostname. What this means for usage in Docker is that we should specify -h
/--hostname
explicitly for each daemon so that we don't get a random hostname and can keep track of our data:
$ docker run -d --hostname my-rabbit --name some-rabbit ziporah/openshift-rabbitmq:3
If you give that a minute, then do docker logs some-rabbit
, you'll see in the output a block similar to:
=INFO REPORT==== 6-Jul-2015::20:47:02 ===
node : rabbit@my-rabbit
home dir : /var/lib/rabbitmq
config file(s) : /etc/rabbitmq/rabbitmq.config
cookie hash : UoNOcDhfxW9uoZ92wh6BjA==
log : tty
sasl log : tty
database dir : /var/lib/rabbitmq/mnesia/rabbit@my-rabbit
Note the database dir
there, especially that it has my "Node Name" appended to the end for the file storage. This image makes all of /var/lib/rabbitmq
a volume by default.
See the RabbitMQ "Clustering Guide" for more information about cookies and why they're necessary.
For setting a consistent cookie (especially useful for clustering but also for remote/cross-container administration via rabbitmqctl
), use RABBITMQ_ERLANG_COOKIE
:
$ docker run -d --hostname my-rabbit --name some-rabbit -e RABBITMQ_ERLANG_COOKIE='secret cookie here' ziporah/openshift-rabbitmq:3
This can then be used from a separate instance to connect:
$ docker run -it --rm --link some-rabbit:my-rabbit -e RABBITMQ_ERLANG_COOKIE='secret cookie here' ziporah/openshift-rabbitmq:3 bash
$ rabbitmqctl -n rabbit@my-rabbit list_users
Listing users ...
guest [administrator]
Alternatively, one can also use RABBITMQ_NODENAME
to make repeated rabbitmqctl
invocations simpler:
$ docker run -it --rm --link some-rabbit:my-rabbit -e RABBITMQ_ERLANG_COOKIE='secret cookie here' -e RABBITMQ_NODENAME=rabbit@my-rabbit ziporah/openshift-rabbitmq:3 bash
$ rabbitmqctl list_users
Listing users ...
guest [administrator]
There is a second set of tags provided with the management plugin installed and enabled by default, which is available on the standard management port of 15672, with the default username and password of guest
/ guest
:
$ docker run -d --hostname my-rabbit --name some-rabbit ziporah/openshift-rabbitmq:3-management
You can access it by visiting http://container-ip:15672
in a browser or, if you need access outside the host, on port 8080:
$ docker run -d --hostname my-rabbit --name some-rabbit -p 8080:15672 ziporah/openshift-rabbitmq:3-management
You can then go to http://localhost:8080
or http://host-ip:8080
in a browser.
If you wish to change the default username and password of guest
/ guest
, you can do so with the RABBITMQ_DEFAULT_USER
and RABBITMQ_DEFAULT_PASS
environmental variables:
$ docker run -d --hostname my-rabbit --name some-rabbit -e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS=password ziporah/openshift-rabbitmq:3-management
You can then go to http://localhost:8080
or http://host-ip:8080
in a browser and use user
/password
to gain access to the management console
If you wish to change the default vhost, you can do so with the RABBITMQ_DEFAULT_VHOST
environmental variables:
$ docker run -d --hostname my-rabbit --name some-rabbit -e RABBITMQ_DEFAULT_VHOST=my_vhost ziporah/openshift-rabbitmq:3-management
See the RabbitMQ "Configuration" for more information about various configuration options.
For enabling the HiPE compiler on startup use RABBITMQ_HIPE_COMPILE
set to 1
. Accroding to the official documentation:
Set to true to precompile parts of RabbitMQ with HiPE, a just-in-time compiler for Erlang. This will increase server throughput at the cost of increased startup time. You might see 20-50% better performance at the cost of a few minutes delay at startup.
It is therefore important to take that startup delay into consideration when configuring health checks, automated clustering etc.
