Release name must not be longer than 53

[tamasborsstriva]

Bug Report

What did you do?

I have custom resource, which's length can be longer than 53 characters.
The resource is synced from a vritual cluster, and the syncer puts extras to the resource name which I can not control.
(adds the name of the namespace in the virtual cluster, and of the name virtual cluster)

What did you expect to see?

operator is able to create the release

What did you see instead? Under which circumstances?

Hi @tamasborsstriva This isn't a limitation in operator-sdk, this is an implementation detail of helm. See Below for more information.
