Using Operator-SDK v1.27.0 (from Makefile at the time)

Goal is to run ./bin/operator-sdk create api --kind TcxNsProgram ... to add a new kind object. As is, can't run in our repo without hitting errors.

Run Command

$ ./bin/operator-sdk create api --group bpfman --version v1alpha1 --kind TcxNsProgram --resource --controller --force --namespaced=true
Error: failed to create API: unable to inject the resource to "base.go.kubebuilder.io/v3": multiple groups are not allowed by default, to enable multi-group visit https://kubebuilder.io/migration/multi-group.html

1. Download kubebuilder and enable multiple groups. Not sure we want multiple groups enabled, but needed it to proceed.

• Used version from same timeframe as Operator-SDK v1.27.0. Tried a couple of versions and this seemed to work.

  cd bpfman-operator/bin
  wget https://github.com/kubernetes-sigs/kubebuilder/releases/download/v3.8.0/kubebuilder_linux_amd64
  mv kubebuilder_linux_amd64 kubebuilder
  chmod +x kubebuilder

• Enable multiple groups:

  cd bpfman-operator
  $ ./bin/kubebuilder edit --multigroup=true
  Error: failed to edit project: unable to scaffold with "base.go.kubebuilder.io/v3": open Dockerfile: no such file or directory

  So copied IngressNodeFirewall Dockerfile. Just creating a blank Dockerfile or renaming one of the existing Containerfiles didn't work. Then complained about not main.go in root, so copied the operator main.go to root.

  $ cp ../../ingress-node-firewall/Dockerfile .
  $ cp cmd/bpfman-operator/main.go .

  Re-run. Resulting command updated PROJECT file. I then changed the repo: manually from repo: github.com/bpfman to repo: github.com/bpfman/bpfman-operator.

  $ ./bin/kubebuilder edit --multigroup=true
  
  $ git diff PROJECT
  diff --git a/PROJECT b/PROJECT
  index fea9a3a..24d680b 100644

2. Rerun operator-sdk command:

   $ ./bin/operator-sdk create api --group bpfman --version v1alpha1 --kind TcxNsProgram --resource --controller --force --namespaced=true
   :
   Error: load packages in root "/home/bmcfall/src/bpfman/bpfman-operator": err: exit status 1: stderr: go: inconsistent vendoring in /home/bmcfall/src/bpfman/bpfman-operator

   Got further, but failed. To fix:

   go mod tidy
   go mod vendor

   Rerun:

   $ ./bin/operator-sdk create api --group bpfman --version v1alpha1 --kind TcxNsProgram --resource --controller --force --namespaced=true

Results

I think because multiple groups is enabled, operator-sdk is placing all the generated code in a groups subdirectory.
