OpenShift Tips

Pull Secrets

Update pull secret without reinstalling

The pull secret required to be able to pull images from the Red Hat registries is stored in the pull-secret secret hosted in the openshift-config namespace.

It is just a matter of modifying that secret with the updated one (in base64):

oc edit secret -n openshift-config pull-secret

NOTE: That secret is translated by the machine-config operator into the /var/lib/kubelet/config.json file so in order to update it is required for the hosts to be rebooted (which is done automatically by the mc operator)

Opt out telemetry

oc -n openshift-config create secret generic pull-secret --from-file=.dockerconfigjson=<(oc extract secret/pull-secret -n openshift-config --to=- | jq -M 'del(.auths[""])') --dry-run=client -o yaml | oc -n openshift-config apply --filename=-

NOTE: This will trigger a reboot in all the nodes.
