lb-docker-rabbitmq

Base docker image to run a RabbitMQ server

Usage

To create the image lastbackend/rabbitmq, execute the following command on the lb-docker-rabbitmq folder:

docker build -t lastbackend/rabbitmq .

Running the RabbitMQ server

Run the following command to start rabbitmq:

docker run -d -p 5672:5672 -p 15672:15672 lastbackend/rabbitmq

The first time that you run your container, a new random password will be set.
To get the password, check the logs of the container by running:

docker logs <CONTAINER_ID>

You will see an output like the following:

    ---------------------------------------- RabbitMQ ---------------------------------------
      +-++-+ curl --user admin:sJZmFTlDejb9sjiDstPHKezJ http://«host»:«port»/api/vhosts"
      | LB |
      +-++-+ Please remember to change the above password!
    -----------------------------------------------------------------------------------------

In this case, sJZmFTlDejb9sjiDstPHKezJ is the password set.
You can then connect to RabbitMQ:

curl --user admin:sJZmFTlDejb9sjiDstPHKezJ  http://<host>:<port>/api/vhosts

Setting a specific password for the admin account

If you want to use a preset password instead of a randomly generated one, you can
set the environment variable PASS to your specific password when running the container:

    ---------------------------------------- RabbitMQ ---------------------------------------
      +-++-+
      | LB | curl --user admin:«password» http://«host»:«port»/api/vhosts"
      +-++-+
    -----------------------------------------------------------------------------------------

docker run -d -p 5672:5672 -p 15672:15672 -e PASS="mypass" lastbackend/rabbitmq

You can now test your new admin password:

curl --user admin:mypass  http://<host>:<port>/api/vhosts

Running a RabbitMQ cluster

To run a cluster with all the DNS-Reachable Host, you have to set RABBITMQ_USE_LONGNAME
and HOSTNAME on first server :

docker run -d \
 -p 5672:5672 -p 15672:15672 -p 35197:35197 -p 4369:4369 -p 25672:25672 \
 -e HOSTNAME=node1.host.io \
 -e RABBITMQ_USE_LONGNAME=true \
 lastbackend/rabbitmq

And add CLUSTER_WITH for the others nodes :

docker run -d \
 -p 5672:5672 -p 15672:15672 -p 35197:35197 -p 4369:4369 -p 25672:25672 \
 -e HOSTNAME=node2.host.io \
 -e RABBITMQ_USE_LONGNAME=true \
 -e CLUSTER_WITH=node1.host.io \
 lastbackend/rabbitmq
