CLI Cheat Sheet

New Project with NodeSelector

oc adm new-project myproject \
    --node-selector='label.key=label.value'

Serivce Accounts

Create service accounts and apply roles:

$ oc create sa cicd
$ oc adm policy add-role-to-user edit -z cicd

Get Service Account Token

$ oc sa get-token <service account name>

Disable Automatic Deployment

OpenShift 3.x

$ oc get dc <dc name> -o yaml -n <project> | sed 's/automatic: true/automatic: false/g' | oc replace -f -

OpenShift 4.x

$ oc patch ...

Get GitHub Webhook Trigger Secret

oc get bc/<build name> -o=jsonpath='{.spec.triggers..github.secret}{"\n"}'

To get the Webhook URL:

oc describe bc/<build name>

Then look for Webhook Github: and copy the URL:. You will have to replace <secret> with the secret you retrieved in the first step.

Set Environment Variable

You can easily set an env var on a deployment config from the cli:

oc set env dc/<dc name> key=value

OpenShift 4 - Expose Image Registry On Custom Route

oc patch configs.imageregistry.operator.openshift.io/cluster --patch '{"spec":{"routes":[{"name":"public-routes","hostname":"registry.apps.<cluster url>"}]}}' --type=merge

oc rollout restart deployment <deployment name> -n <namespace>
