35MB RabbitMQ Docker image running on Alpine Linux

Alpine Linux RabbitMQ Docker image

Many other RabbitMQ Docker images are huge. Instead of using the bloated Ubuntu or Fedora images as a base, this image uses the 5MB Alpine Linux base image. Alpine lets us run RabbitMQ 3.5.4 on Erlang 18.0.2 in only 35MB!

Usage

The wrapper script starts RabbitMQ (with management plugin enabled), tails the log, and configures listeners on the standard ports:

• 5671/tcp: Listening port when SSL is enabled
• 5672/tcp: Non-SSL default listening port
• 15671/tcp: SSL GUI listening port
• 15672/tcp: Non-SSL GUI listening port

RabbitMQ's data is persisted to a volume at /var/lib/rabbitmq.

To enable SSL set the $SSL_CERT_FILE, $SSL_KEY_FILE, and $SSL_CA_FILE environment variables. The wrapper script will use the same certs for GUI SSL access as for AMQPS access.

Example:

docker run -it \
  --name rabbitmq \
  -p 5671:5671 \
  -p 15671:15671 \
  -e SSL_CERT_FILE=/ssl/cert/cert.pem \
  -e SSL_KEY_FILE=/ssl/cert/key.pem \
  -e SSL_CA_FILE=/ssl/CA/cacert.pem \

Customizing

To set a custom config, ditch the wrapper script and call rabbitmq-server directly. Place the custom config in /srv/rabbitmq_server-3.5.4/etc/rabbitmq/.

Fair Warning!

Alpine's Erlang packages are in its edge (testing) repo, if that bothers you then don't use this image!
