Bug Report

What did you do?

Upgraded the operator-sdk to version v0.15.0, and used operator-sdk generate crds, to generate crd from spec : https://github.com/Orange-OpenSource/casskop/blob/master/pkg/apis/db/v1alpha1/cassandracluster_types.go#L818

What did you expect to see?

Having my crd object generated with the following logs :

$ operator-sdk generate crds
INFO[0000] Running CRD generator.
INFO[0001] CRD generation complete.

What did you see instead? Under which circumstances?

$ operator-sdk generate crds  
INFO[0000] Running CRD generator.
/Users/aguitton/workspace/casskop/casskop/pkg/apis/db/v1alpha1/cassandracluster_types.go:819:33: map values must be a named type, not *ast.StarExpr
FATA[0001] error generating CRDs from APIs in pkg/apis: error generating CRD manifests: error running CRD generator: not all generators ran successfull

Environment

• operator-sdk version : v0.15.0
• go-version : 0.13

Possible Solution

The operator sdk have a dependency to sigs.k8s.io/controller-tools v0.2.4, which perform the schema validation during the crd generation, this module is the root cause of the error.

To fix this, there is a PR : kubernetes-sigs/controller-tools#317, which is not merged yet. Once the merge will be done, update the dependency should be enough (until it's done we forked the operator-sdk and the controller-tool).
