adding a new kubernetes node pool to existing cluster with regular channel as release channel

问题

I'm trying to add a new node pool into an existing GKE cluster. Failing with the below error.

Node pool version cannot be set to 1.14.6-gke.1 when releaseChannel REGULAR is set.

Any advice on how i can get around this?

EDIT: I finally managed to create a new pool but only after my master was auto-updated. looks like for auto-updated clusters this is a limitation. the new node being created seems to default to the version of the master and if the master is on a deprecated version and is pending auto upgrade, all one can do it wait.

That version was removed from GKE yesterday: https://cloud.google.com/kubernetes-engine/docs/release-notes#version_updates

The following versions are no longer available for new clusters or upgrades.

    1.13.7-gke.24
    1.13.9-gke.3
    1.13.9-gke.11
    1.13.10-gke.0
    1.13.10-gke.7
    1.14.6-gke.1
    1.14.6-gke.2
    1.14.6-gke.13

It seems you have enrolled the cluster in a REGULAR release channel and you can not currently disable[1] the release channel to do manual upgrades. You need to wait for the auto upgrade as described in the release notes[2].

To stop using release channels and go back to specifying an exact version, you must recreate the cluster without the --release-channel flag.

When you're using a release channel the web cloud console does not let you select a version when creating a node pool, but the API/CLI does.

I'm in the same situation as you: the release channel version that my master is on was revoked, but I was able to add a new node pool with a previous version set in terraform.
