My Openshift Cheatsheet

Openshift build secrets for cloning git repos using SSH Keys

To create ssh secret:

oc create secret generic sshsecret \
    --from-file=ssh-privatekey=$HOME/.ssh/id_rsa

to inform a different ssh key; limit hosts; etc

ansible -b -i ec2.py all \
 --limit '!x.y.z.w' \
 --key-file '~/.ssh/aws_ec2' \
 -m shell -a 'subscription-manager list --pool-only --consumed'
