"apt-get -y install rabbitmq-server" hangs when installed via a playbook

When I run the following task from a playbook, it hangs forever:

  • command: apt-get -y install rabbitmq-server

If I instead run it from the command line, it works just fine:

ansible ec2-host.compute-1.amazonaws.com -m command -a “apt-get -y install rabbitmq-server” --user=ubuntu --sudo --private-key=/root/.ssh/mykey.pem

Any thoughts on how to fix this?

Here is the output from ps on the VM. Notice “[apt-get] ”

Seems like the init script is not daemonizing properly.

3

This isn’t directly relevant to your problem, but is there a reason you’re using the command module instead of the apt module for installing this package?

4

I had started with the apt module (providing about 20 packages using with_items), but it was hanging so I quickly determined it was rabbitmq-server that was causing the issue so then I started debugging it.

Turns out it has to do with fireball mode. Switched back to paramiko and it works.

apt-get + rabbitmq-server + fireball = fail (for now)

Ok, if you have any fixes for fireball mode, they are welcome.
