A simple Docker image to run Foreman
-h to a hostname, that's what Foreman and Puppet will use as fqdn.
docker run -ti -h foreman.local --name foreman -p 443:443 -p 8443:8443 -p 8140:8140 csanchez/foreman
Then go to port 443 of your docker host (e.g. http://localhost:443)
To see more hosts in Foreman, you can run more Puppet agents
docker run --link foreman:puppet --rm -ti csanchez/foreman /puppet-agent.sh puppet
Then sign the new certificate in Foreman under Infrastructure -> Smart Proxies -> Certificates.
If you want to open a shell session and play with the installed Puppet and other tools
docker run -ti -h foreman.local -p 8443:443 csanchez/foreman bash
foreman-installer to customize the instance with the new hostname,
and anything else you want to run.
foreman-installer puppet agent --test ...
Create your Dockerfile and run any commands, eg. to install the docker plugin (
FROM csanchez/foreman RUN yum -y install ruby193-rubygem-foreman_docker
docker build -t csanchez/foreman .
