We're trying to take advantage of some of the new features in the v1.1.1 Kubernetes release by upgrading our cluster running on Google Container Engine.
On the release notes Google states that cluster masters are currently running v1.1.1. However, when trying to upgrade our existing cluster nodes (following the cluster upgrade docs), I get the following the trace:
Failed to start node upgrade: Desired node version (1.1.1) cannot be greater than current master version (1.0.7)
This is confirmed by running kubectl version:
Client Version: version.Info{Major:"1", Minor:"1", GitVersion:"v1.1.1", GitCommit:"92635e23dfafb2ddc828c8ac6c03c7a7205a84d8", GitTreeState:"clean"} Server Version: version.Info{Major:"1", Minor:"0", GitVersion:"v1.0.7", GitCommit:"6234d6a0abd3323cd08c52602e4a91e47fc9491c", GitTreeState:"clean"}
All the while, the gcloud console reports a cluster api version of 1.0.6.
Are the master upgrades still in process for existing clusters? Does a timeline exist on that? Earlier release notes mention a 1 week runway for existing cluster version upgrades; we've just surpassed that window from the release date of v1.1.1.
The release notes state that "Kubernetes v1.1.1 is the default version for new clusters" (emphasis added). Existing clusters will be upgraded from 1.0 to 1.1 in the coming weeks. If you want to take advantage of the 1.1 features immediately you can create a new cluster at 1.1 or contact us on the #google-containers channel on Slack to ask for your cluster to be upgraded sooner.
