The default behaviour of Cobra library is to add default help cmd as late as possible to allow modifications. However, in case of kn initialization of help is superseded by plugin parsing and fails with unknown command error.

➜  client git:(issue-533) kn help
Error: unknown command 'help' 
Run 'kn --help' for usage.

This change brings back help as a command and enables usage of both kn help and kn help <sub-command>.

Proposed Changes

  • Add early initialization of default help command.
