I'm trying to run oc cluster up - the Openshift 3.11 development environment - in an offline environment.
I have run it previously while online, and so the required images are downloaded.
Then I modified these files and set
- ./openshift.local.clusterup/static-pod-manifests/apiserver.yaml
- ./openshift.local.clusterup/static-pod-manifests/etcd.yaml
- ./openshift.local.clusterup/static-pod-manifests/kube-controller-manager.yaml
- ./openshift.local.clusterup/static-pod-manifests/kube-scheduler.yaml
And set imagePullPolicy: IfNotPresent.
However, when subsequently running oc cluster up the files are written over, and again set to imagePullPolicy: Always.
I then tried setting the above files to be eadonly, but the oc cluster up fails with a permission error.
Update
I found that the following command - oc cluster up --tag=v3.11 - will create .yaml that include imagePullPolicy: IfNotPresent however oc cluster up still fails to start without internet access.
