Unreadable configmaps with -oyaml

General Discussions

I have installed jenkins using this guide:

in a local 1.21 kubernetes cluster which creates some configmaps from e.g.:

  values:
    controller:
      JCasC:
        securityRealm: |-
          local:
            allowsSignup: false
            enableCaptcha: false
            users:
            - id: "admin"
              name: "Jenkins Admin"
              password: "secret12345"
        authorizationStrategy: |-
          loggedInUsersCanDoAnything:
            allowAnonymousRead: false

When I output one of those configmaps it looks like this (from a terminal in ubuntu):

$ kubectl get cm jenkins-jenkins-jcasc-config -oyaml
apiVersion: v1
data:
  jcasc-default-config.yaml: "jenkins:\n  authorizationStrategy:\n    loggedInUsersCanDoAnything:\n

which is unreadable. Whis is it formatted like like and is there any way to avoid that - outputting in prettyprint (avoid all the back-slashes etc)?
