OpenShift Named Certificates

This is a short guide explaining how to deploy and manage custom SNI or "named" certificates via openshift-ansible. These custom certificates will be served for public facing console and API.

1. Setting up
2. Install using master.public-example.com certificate

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

Cluster Quota

oc create clusterquota env-qa \

oc create clusterquota user-qa \

Run Chef scripts locally

There are several options to run recipes:

using chef-client with -z option
using chef-apply
using chef-solo

Before running Chef recipes on the machine, it should be prepared:

# Delete all containers
docker rm $(docker ps -aq)
# Delete all images
docker rmi $(docker images -q)
# Delete all untagged images
docker rmi $(docker images -q --filter "dangling=true")

Run commands on remote Docker host

This is how to connect to another host with your docker client, without modifying your local Docker installation or when you don't have a local Docker installation.

Enable Docker Remote API

First be sure to enable the Docker Remote API on the remote host.

This can easily be done with a container.
For HTTP connection use jarkt/docker-remote-api.
