@chrono2002 you didn't use the make manifests to generate the CRDs, so your modifications will be deleted each time the make manifests command will be played

Yeah, @chrono2002 you'll need to change the go struct definition first and the crd yamls are generated automatically by running:

make manifests
make generate
make fmt 
make vet
make docs-update

Here're some examples: https://github.com/fluent/fluent-operator/pull/1018 https://github.com/fluent/fluent-operator/pull/972
