How exactly do you upgrade to 0.17?
Did you upgrade crds or just update image in deployment?

Could you share the results for following command?

kubectl get deploy --all-namespaces | grep clickhouse-operator

Upgrade operator first, then upgrade crd.

[Slach]

Could you upgrade CRDs first
your deployment not look like after standard installation way
it should be clickhouse-operator instead of clickhouse-operator-altinity-clickhouse-operator?
Did you use some Helm chart or something else?

Could you remove this deployment (it safe)

kubecetl delete deploy -n kube-system clickhouse-operator-altinity-clickhouse-operator

after it and just apply

kubectl apply -f https://raw.githubusercontent.com/Altinity/clickhouse-operator/master/deploy/operator/clickhouse-operator-install-bundle.yaml

and check results

kubectl get deploy clickhouse-operator -n kube-system

I wrote the helm chart deployment myself

[Slach]

@czhfe ok. try update crds
in your helm chart
and re-install clickhouse-operator

[czhfe]

@czhfe ok. try update crds in your helm chart and re-install clickhouse-operator

Now I do not understand why the operator and crd updated here will error, there is no solution

[Slach]

It solution cause new CRDs define status as subresources.

Compare your current CRDs with
https://raw.githubusercontent.com/Altinity/clickhouse-operator/master/deploy/operator/clickhouse-operator-install-bundle.yaml

I upgraded from 0.13.5 to 0.17

[czhfe]

Upgrade from clickhouse-operator 0.13.5 to 0.17.0. perform the following steps.

1. Upgrade crd first
2. Upgrade operator and other resources

After the upgrade, modify ClickHouseInstallation CR encountered the following error

[Slach]

Do you have status in your edited resource? If yes, please remove this sections and try to save

Could you share the following command results?

kubectl get chi -n ch1 clickhouse -o yaml

Could you share the following command results?

kubectl get chi -n ch1 clickhouse -o yaml

Yes, I have tested this before by deleting the status section and trying to save it later, but the result is still the same.

Problem recurrence：

The /spec/templating/policy in the clickhouseinstallations.clickhouse.altinity.com CRD prior to version 0.16.0 did not have its default value explicitly defined, resulting in that default value being "".
The clickhouseinstallations.clickhouse.altinity.com CRD was upgraded in version 0.16.0 of the clickhouse operator (this can be seen in the release notes in RELEASES).
In version 0.16.0 and later /spec/templating/policy was changed to be configurable as auto or manual, with the default value being manual. clickhouseinstallations.clickhouse.altinity.com before 0.16.0
CR before 0.16.0 did not explicitly define that the /spec/templating/policy field would be added automatically, so clickhouse operators and CRD versions after 0.16.0 cannot automatically update the /spec/templating/policy field, which would block
clickhouse operator to update the CR for clickhouseinstallations.clickhouse.altinity.com, which causes an error

Should be fixed in earlier released, but additional rules were added at https://github.com/Altinity/clickhouse-operator/releases/tag/release-0.22.1
