Add content to "Administering Jenkins on Kubernetes"

[StackScribe]

We have a stub page entitled "Administering Jenkins on Kubernetes" but it has no content. It should include a link to the Kubernetes Installation page and then have more information.

As explained in https://github.com/jenkins-infra/jenkins.io/pull/5547#pullrequestreview-1144145025 , we should list what is expected in any PR to add content.

• Good point to mention some base Kubernetes concepts pointing to external sites (not sure it is worth duplicating this kind of content)
• I do not see the point of the "Kubernetes Upgrade" ? Do you mean "upgrading Jenkins in Kubernetes" ?
• Add a link to the "Jenkins Installation on Kubernetes" page as one of the first steps
• I'm not used to get the usual "Administering Jenkins" pages but I would expect the same "usual" topics as the other pages (haven't check them though: might be scoped to this page only):
  • Installation of Jenkins in Kubernetes (point to the page with the requirements, the different method with helm chart as recommended default)
  • Managing Jenkins Controller image (install plugin on each restart vs. forge your own container image)
  • Managing network to the Jenkins controller:
  • inbound connections:
    • HTTP: WebUI and websockets external agents, API access, websocket access (Svc + Ingress)
    • TCP: inbound external agents (Svc, or TCP-ingress - advanced topic)
  • outbound connections
  • Managing Agents (Kubernetes plugin for container agents, but also adding agents outside Kubernetes such as permanent agents or cloud agents), separated namespaces, autoscaling, etc.
  • Managing data (backup/restore of the Jenkins Home)
  • Managing Secrets (Kubernetes Secrets, SVC accounts to access Kubernetes API)
  • Managing Jenkins upgrades
  • Monitoring Jenkins in Kubernetes

WDYT?
