Using regular expressions in CEL Interceptros

[pvlltvk]

Hi everyone!

Is it possible to use regexp in CEL Interceptors to filter events? For instance, can i use constructions like this:

interceptors:
  - cel:
      filter: body.ref == 'tekton/.*'"

Hi @pvlltvk sorry for the delay in responding. CEL supports regular expressions using the built in matches function.
(See the matches function here: https://github.com/google/cel-spec/blob/master/doc/langdef.md#list-of-standard-definitions)

So, something like body.ref.matches('tekton/.*') should work.
