Atlas setup for ActiveMQ

This is a set of Atlas configs to bring up a network of Apache ActiveMQ brokers.

To use it, first build download the atlas binary (or check it out and build it) and make it executable (chmod +x ./atlas). The binary requires Java 1.6, so have Java installed, put that executable on your path and cd into your checkout of this project.

$ atlas -e ./env-ec2.rb -s sys-activemq.rb init
$ atlas update

It should ask you for your EC2 access credentials (get them here). Then it will take a while as it spins up EC2 instances, installs, and wires things up. Once it finishes, you can see what is there and ssh into instances:

$ atlas ls
$ atlas ssh shell

The shell host has a small ruby script at ~/smoke_test.rb that connects to different brokers in the network and sends a message. Run it via

$ ./smoke_test.rb

And you should get a message telling you that it works. Play around with it and have fun!

When you are finished playing, you can tear down the servers that were set up with:

$ atlas destroy

When you want to play again you can go in and start them via atlas update again. Do the work from the same directory as it stores state (like your AWS access credentials) .atlas/.

Notes:

• ActiveMQ is installed under /opt/activemq
• The brokers are listening for OpenWire on port 61616, Stomp on 61612, and Stomp+NIO on 61613
• The best way to restart a broker is sudo service activemq restart
• The progress bars get confused sometimes, sorry.
