@praveen4g0 This is a tricky one, but two points

• It should be on tkn version instead of tkn pipeline version
• We don't have a way yet to return the version from the controller (without a huge hack). See Add version label to pipelines controller deployment pipeline#1543

Also, kn is going to return the api version instead of the "knative release version". I think it might make more sense as it is what make the contract. But this is open to questions 👼 😉

Dupe of #159. I'll close #159 though since a lot of the conversation is happening here.

@waveywaves that one is a tricky one fyi, which involves some hard to tackle change in pipeline (to answer the question "what is the pipeline version" question)

Yes I was just checking that out. I was thinking something along the lines of https://github.com/kubernetes/kubernetes/tree/7f23a743e8c23ac6489340bbb34fa6f1d392db9d/staging/src/k8s.io/client-go/pkg/version in tektoncd/pipeline
