How to upgrade Zalando postgres-operator?

Question

I have been using Zalando Postgres operator for deploying Postgres databases on DigitalOcean. I want to upgrade my postgres operator but I don't seem to know what I should be doing.

I do the following to get operator deployed:

NAME                                 READY   STATUS    RESTARTS      AGE
postgres-operator-58b75c5587-wsl8m   1/1     Running   5 (60m ago)   15d

I tried the following but I get errors:

 helm upgrade postgres-operator charts/postgres-operator/postgres-operator-1.10.0.tgz -f charts/postgres-operator/values.yaml 

Error: UPGRADE FAILED: error validating "": error validating data:

How am I supposed to upgrade the postgres operator? Any help?

Answer 1

I had to apply the crds first like it was mentioned here :

you need to install crd-s first

k apply -f https://raw.githubusercontent.com/zalando/postgres-operator/master/charts/postgres-operator/crds/operatorconfigurations.yaml
k apply -f https://raw.githubusercontent.com/zalando/postgres-operator/master/charts/postgres-operator/crds/postgresqls.yaml
k apply -f https://raw.githubusercontent.com/zalando/postgres-operator/master/charts/postgres-operator/crds/postgresteams.yaml
https://postgres-operator.readthedocs.io/en/latest/administrator/#upgrading-the-operator

They also mentioned: When using helm, be aware that installing the new chart will not update the Postgresql and OperatorConfiguration CRD. Make sure to update them before with the provided manifests in the crds folder. Otherwise, you might face errors about new Postgres manifest or configuration options being unknown to the CRD schema validation.

K is an alias for kubectl. Create alias k=kubectl like this. Then the upgrade worked.
