Capistrano Deployment from Jenkins

  • submit to reddit

Recently I had a challenge of getting capistrano deployments working from jenkins installed on a RHEL box. The problem seemed to be down to the fact that ssh-agent isn’t running for the daemon process that jenkins runs as for whatever reason and it is needed to do ssh agent forwarding (which is what I do so I can use the ssh key on the jenkins server to check code out from github on remote servers).

After banging my head against the head for a couple hours, I came up with a simple solution: execute a shell script through ssh-agent. I simply created a script in the root of my project with the following contents:

cap $1 deploy

Then execute it through ssh agent.

exec /usr/bin/ssh-agent "${WORSKPACE}/" "production"

Works perfectly. Hopefully this helps someone else, took me a lot of grief to figure this out.

Oh yeah, in case you didn’t know, I’m back in PHP development again for awhile so there should be some interesting posts ahead. :)
