Introduction

Dockerfile to build a ActiveMQ container image.

Version

Current Version: 5.13.2

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'\
        -P
	webcenter/activemq:latest

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 ;)

Contributing

• Send a Pull Request with your awesome new features and bug fixes
• Help new users with Issues they may encounter

Issues

Docker is a relatively new project and is active being developed and tested by a thriving community of developers and testers and every release of docker features many enhancements and bugfixes.

Given the nature of the development and release cycle it is very important that you have the latest version of docker installed because any issue that you encounter might have already been fixed with a newer docker release.

For ubuntu users I suggest installing docker using docker's own package repository since the version of docker packaged in the ubuntu repositories are a little dated.

Here is the shortform of the installation of an updated version of docker on ubuntu.

sudo apt-get purge docker.io
curl -s https://get.docker.io/ubuntu/ | sudo sh
sudo apt-get update
sudo apt-get install lxc-docker

Fedora and RHEL/CentOS users should try disabling selinux with setenforce 0 and check if resolves the issue. If it does than there is not much that I can help you with. You can either stick with selinux disabled (not recommended by redhat) or switch to using ubuntu.

If using the latest docker version and/or disabling selinux does not fix the issue then please file a issue request on the issues page.

In your issue report please make sure you provide the following information:

• The host distribution and release version.
• Output of the docker version command
• Output of the docker info command
• The docker run command you used to run the image (mask out the sensitive bits).

Installation

Pull the image from the docker index. This is the recommended method of installation as it is easier to update image. These builds are performed by the Docker Trusted Build service.

docker pull webcenter/activemq:5.13.2

You can also pull the latest tag which is built from the repository HEAD

docker pull webcenter/activemq:latest

Alternately you can build the image locally.

git clone https://github.com/disaster37/activemq.git
cd activemq
docker build --tag="$USER/activemq" .

Quick Start

You can launch the image using the docker command line :

• For test purpose :

docker run --name='activemq' -it --rm -P \
webcenter/activemq: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' \
-e 'ACTIVEMQ_ENABLED_SCHEDULER=true' \
-v /data/activemq:/data/activemq \
-v /var/log/activemq:/var/log/activemq \
-p 8161:8161 \
-p 61616:61616 \
-p 61613:61613 \
webcenter/activemq:5.13.2

Or you can use fig. Assuming you have fig installed,

wget https://raw.githubusercontent.com/disaster37/activemq/master/fig.yml

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
