Templates in ClickHouseKeeperInstallation are not used

[ShuaiShao93]

It looks like there is no way to use the templates in https://github.com/Altinity/clickhouse-operator/blob/master/docs/chk-examples/02-extended-3-nodes.yaml#L26-L66, so specifying them is not useful.

I tried to add defaults but got

error validating data: ValidationError(ClickHouseKeeperInstallation.spec): unknown field "defaults" in com.altinity.clickhouse-keeper.v1.ClickHouseKeeperInstallation.spec

[Slach]

could you check prepelease clickhouse-operator:0.24.0?

look
https://github.com/Altinity/clickhouse-operator/blob/0.24.0/docs/chk-examples/02-extended-3-nodes.yaml

and
https://github.com/Altinity/clickhouse-operator/tree/0.24.0/deploy/operator

This works, thank you! When will 0.24 go out formally?

we don't provide any ETA
kind: ClickHouseInstallationKeeper now in deep refactoring

@Slach the ClickHouseInstallationKeeper works for some cluster, but exactly the same manifest doesn't work for another cluster for some reason. Looks like the defaults didn't take effect. I'm testing different kubernetes versions to figure out why, but do you have any thoughts why this may happen?

@ShuaiShao93 which is your kubernetes version?

@ShuaiShao93 which is your kubernetes version?

Yeah I figured this out. The keeper 0.24.0 requires at least kubernetes 1.29. After upgrading, it works now. Thanks!

I encountered the same issue, and our cluster can't be upgraded to v1.29 easily.

After I modified the generated statefulset, the chi CRD object won't reconcile successfully

Sorry my mistake, didn't fill in the spec.defaults.templates.podTemplate name correctly
