Description of the change:

  • pkg/test: only register --kubeconfig if not registered, get value if already registered

Motivation for the change: controller-runtime currently adds the --kubeconfig flag if pkg/client/config is imported (set up in an init() function). The SDK's test framework also adds this flag, which will panic if both packages are imported and the test framework is initialized.

Closes: kubernetes-sigs/controller-runtime#878

Description of the change:

  • pkg/test: use local flag.FlagSet instead of flag.CommandLine

Motivation for the change: controller-runtime currently adds the --kubeconfig flag if pkg/client/config is imported (set up in an init() function). The SDK's test framework also adds this flag, which will panic if both packages are imported and the test framework is initialized. This commit creates a new flag.FlagSet for the test framework instead of using the global one.

overall lgtm, I would add a test though. And confirm or deny my understanding of the flag parsing. If I misunderstood it, then we should add a changelog entry. If not, no changelog entry required.

pkg/client/config is imported (set up in an init() function).

if both are imported and the test framework is initialized.
This commit only registers --kubeconfig if it is not already
registered, and gets its value if so.

Hi @akieling,

SDK is in the version 0.18.2 already. So, 0.15.x is quite old and we would like to recommend you uprade your project.
See its Backport Policy in https://sdk.operatorframework.io/docs/contribution-guidelines/backport-policy/
