Anyone knows if Scheduled Jobs is already available in GKE 1.4.3?
I get the following when I try to deploy
error validating "letsencrypt-sj.yaml": error validating data: couldn't find type: v2alpha1.ScheduledJob; if you choose to ignore these errors, turn validation off with --validate=falsScheduled Jobs are currently an alpha feature in Kubernetes 1.4, so they are not available in a normal GKE cluster (because alpha features are subject to breaking changes at any time).
Until Scheduled Jobs reach beta status and become available by default, you can create an alpha cluster to test them in GKE.
