@MbolotSuse The ci-build is failing with error

go: downloading github.com/josharian/intern v1.0.0

I am guessing that I also need to update the client-go version in https://github.com/rancher/csp-adapter/pull/76/files#diff-33ef32bf6c23acb95f5902d7097b7a1d5128ca061167ec0716715b0b9eeaa5f6L13 but the PR for that is still in WIP rancher/client-go#7 .

Looks good.

@chajain Looks like the CI is failing due to the adapter failing to build. You will need to update the client-go version as well. I would recommend putting this PR on hold until that work is complete.
