Failed to deploy the operator on my minikube cluster (v1.18.2):

The operator has problem with k8s 1.18, we will fix it. As a work around, you might use a lower version.

Anything I can do to help fix this? I can't really downgrade my Kubernetes on premise cluster and I would really like to give the operator a try.

As a temporary workaround, the crd will deploy (on 1.18 in my case) by removing the instances of protocol from the several x-kubernetes-list-map-keys arrays in the generated crd.

I actually tried something like that (I added protocol to the required properties) and the deploy worked but I am now stuck with the Server-side apply problems (The FlinkCluster "beam-flink-cluster" is invalid: metadata.managedFields.fieldsType: Invalid value: "": must be FieldsV1) when creating the FlinkCluster in /example

If you must use k8s 1.18, it seems that you can avoid this problem by changing controller-gen version 0.2.4 in Makefile as a workaround.

[Enzo90910]

I confirm switching to controller-gen 0.2.4 functions as a workaround for this issue.

Thanks for the suggested workaound, Saved my time while setting up the operator for first time

i changed following line (60) in Make file and it worked
"go get sigs.k8s.io/controller-tools/cmd/controller-gen@v0.3.0 ;"
to
"go get sigs.k8s.io/controller-tools/cmd/controller-gen@v0.2.4 ;"

i got the similar problem when deploying the operator to v1.18 with the yaml file,is it also because of the k8s verson ? and how can i help to fix this?
i just run kubectl create -f https://raw.githubusercontent.com/GoogleCloudPlatform/flink-on-k8s-operator/master/config/crd/bases/flinkoperator.k8s.io_flinkclusters.yaml
,and it output that
`The CustomResourceDefinition "flinkclusters.flinkoperator.k8s.io" is invalid:

Did you tried changing here https://github.com/GoogleCloudPlatform/flink-on-k8s-operator/blob/master/Makefile#L65 and did local build & applied in your K8s v1.18 cluster?

For local build maybe you will be interested in this page https://github.com/GoogleCloudPlatform/flink-on-k8s-operator/blob/master/docs/developer_guide.md#developer-guide

[hwk42]

I did othing to change,just follow the guide https://github.com/GoogleCloudPlatform/flink-on-k8s-operator/blob/master/helm-chart/flink-operator/README.md#installing-the-chart to deploy.
