Jenkins and Jenkins-slave charms

[Steve Powell]

Hi,
I’m a new user of juju, and am setting up a Jenkins instance and couple of slaves on ec2.

Can anyone point me to some doc for the charms jenkins and jenkins-slave that explain the settings and/or config?

I have issued the following commands (in this order — with suitable pauses to wait for completion):

$ juju deploy jenkins
$ juju deploy -n 2 jenkins-slave
$ juju add-relation jenkins jenkins-slave
$ juju set jenkins password=……   
$ juju set jenkins-slave tools="git gcc make bzr mercurial erlang"
$ juju expose jenkins

I can see the jenkins dashboard and log in with admin password, as expected. However, there are no slaves ‘connected’ to the master.

There is a worrying message in status:

services:
  jenkins:
    charm: cs:precise/jenkins-8
    exposed: true
    relations:
      master:
      - jenkins-slave
    units:
      jenkins/0:
        agent-state: error
        agent-state-info: 'hook failed: "master-relation-changed"'
        agent-version: 1.16.5
        machine: "1"
        open-ports:
        - 8080/tcp
        public-address:  ……

Which makes me think the relation wasn’t added correctly.  Removing the relation and re-applying it seems to make no difference to the status at all (the error agent-state is there at all times).

How do I find out what is supposed to happen and what has actually happened?
