Setup an Openshift Docker Runner on Gitlab Enterprise#
When you install openshift - you get an already running default docker registry. You also get a default route…you get alot of things.
Unfortunately the dev experience can still be quite bad without your continuous integration hooked up.
So I’m going to attempt to explain how to link up your corporate gitlab environment to Openshift for easy building, testing and deploying.
There was a semi-decent video on Deploying from gitlab to Openshift OKD however he missed the most important part…creating the template on OKD.
So what is the current status of your infrastructure:
- A gitlab enterprise edition
- An Openshift OKD cluster
Usually if you have added a
.gitlab-ci.yml to your project and there are no gitlab runners configured it will be in a paused state for an hour with a message like:
There are no runners configured for your project
The first thing you need to do isinstall and register a gitlab runner
Importantly if you are using the linux repo, you need to install docker engine on the gitlab host before installing the gitlab runner.
Use the steps here:
curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh | sudo bash sudo apt-get install gitlab-runner apt-cache madison gitlab-runner sudo apt-get install gitlab-runner=10.0.0
You then need to register the runner:
To do this you need 2 things: 1. You need a seperate place other than gitlab to install the runner 2. You need to have obtained a token
Obtaining the Shared Runner Token#
Grab the shared-Runner token on the
Then you need to create a new project on openshift using openshift-examples
oc new-project gitlab # Allow the project to run as root oc adm policy add-scc-to-user anyuid -z gitlab-ce-user -n gitlab oc adm policy add-scc-to-user privileged -z gitlab-runner-user -n gitlab oc apply -f https://raw.githubusercontent.com/debianmaster/openshift-examples/master/gitlab-ci-with-openshift/gitlab-runner.yaml
Then go to the frontend and deploy the image
This worked…until I commited to my project and the runner failed becasue the pod containing 3 containers to run the tests did not work.
