Hi,

Using the generic webhook trigger plugin myself, while still relying on
OpenShift authentication logging into Jenkins, I don't remember having
anything like this.
Although I can't explain why your plugin would refuse this, unless maybe
something's wrong in Jenkins permissions matrix?

As far as I've seen, generic triggers from a BuildConfig wouldn't allow for
multi-branch jobs - or if they do, I'm still looking for a way to retrieve
the triggering branch as a variable somewhere (note: that ruddra sample
shows the buildconfig has a "ref: master", which would suggest it is not
multi-branch capable).
So far, Jenkins plugins was my next best solution, although not ideal.


Anyway, you might be able to create a role - or clusterrole - and
corresponding binding, with something like this (not tested)

- apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: bitbucket-jenkins-hook
  rules:
  - nonResourceURLs: [ "/bitbucket-scmsource-hook/*" ]
    verbs: [ "get", "post" ]

- apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRoleBinding
  metadata:
    name: bitbucket-jenkins-hook
  roleRef:
    apiGroup: rbac.authorization.k8s.io
    kind: ClusterRole
    name: bitbucket-jenkins-hook
  subjects:
  - apiGroup: rbac.authorization.k8s.io
    kind: Group
    name: system:unauthenticated
  - apiGroup: rbac.authorization.k8s.io
    kind: Group
    name: system:authenticated

(see: https://kubernetes.io/docs/reference/access-authn-authz/rbac/)
