Introduction

Dockerfile to build a ActiveMQ container image.

ActiveMQ has no gui, so we will be fine with openjdk-6-jre-headless because is the "Minimal Java runtime - needed for executing non GUI Java programs".

Version

Current Version: 5.11.1

Hardware Requirements

CPU

  • No stats avaible to say the number of core in function of messages

Memory

  • 512MB is too little memory, i think is to use ActiveMQ on test environment
  • 1GB is the standard memory size

You can set the memory that you need :

docker run --name='activemq' -it --rm \
    -e 'ACTIVEMQ_MIN_MEMORY=512' \
    -e 'ACTIVEMQ_MAX_MEMORY=2048'\
    parana/soma-queue

This sample lauch ActiveMQ in docker with 512 MB of memory, and then ActiveMQ can take 2048 MB of max memory

Storage

The necessary hard drive space depends if you use persistant message or not and the type of appender. Normaly, no need space for ActiveMQ because the most data are contains directly on memory.
I think it's depend how you use ActiveMQ ;)

Quick Start

You can launch the image using the docker command line :

  • For test purpose :
docker run --name='activemq' -it --rm parana/soma-queue:latest

The account admin is "admin" and password is "admin". All settings is the default ActiveMQ's settings.

  • For production purpose :
docker run --name='activemq' -d \
-e 'ACTIVEMQ_NAME=amqp-srv1' \
-e 'ACTIVEMQ_REMOVE_DEFAULT_ACCOUNT=true' \
-e 'ACTIVEMQ_ADMIN_LOGIN=admin' -e 'ACTIVEMQ_ADMIN_PASSWORD=your_password' \
-e 'ACTIVEMQ_WRITE_LOGIN=producer_login' -e 'ACTIVEMQ_WRITE_PASSWORD=producer_password' \
-e 'ACTIVEMQ_READ_LOGIN=consumer_login' -e 'ACTIVEMQ_READ_PASSWORD=consumer_password' \
-e 'ACTIVEMQ_JMX_LOGIN=jmx_login' -e 'ACTIVEMQ_JMX_PASSWORD=jmx_password' \
-e 'ACTIVEMQ_STATIC_TOPICS=topic1;topic2;topic3' \
-e 'ACTIVEMQ_STATIC_QUEUES=queue1;queue2;queue3' \
-e 'ACTIVEMQ_MIN_MEMORY=1024' -e  'ACTIVEMQ_MAX_MEMORY=4096' \
-v /data/activemq:/data/activemq \
-v /var/log/activemq:/var/log/activemq \
parana/soma-queue

Configuration

Avaible Configuration Parameters

*Please refer the docker run command options for the --env-file flag where you can specify all required environment variables in a single file. This will save you from writing a potentially long docker run command. Alternately you can use Docker Compose

  • ACTIVEMQ_STATIC_QUEUES: The list of queues separated by comma witch is created when ActiveMQ start.

Advance configuration

For advance configuration, the best way is to read ActiveMQ documentation and created your own setting file like activemq.xml.
Next, you can mount it when you run this image or you can create your own image (base on this image) and include your specifics config file.

The home of ActiveMQ is in /opt/activemq, so if you want to override all the setting, you can launch docker with -v /your_path/conf:/opt/activemq/conf
