pmoranga / Checking your Raspberry Pi's view of its power supply.md

Checking your Raspberry Pi's view of its power supply (sometimes it's not the wall-wart)

Checking your Raspberry Pi's view of its power supply

Sometimes it seems like the first (and sometimes only) advice you get offered for almost any problem with a Raspberry Pi is "check your power supply". You think something like:

"hey, I'm using an official power supply sold as being matched with my Pi so how can there be any problem?"

You look up the specs then stick a controlled load across your supply and confirm that it can deliver the required number of Watts.

Yet your problems persist…

ArgoCD & Kapitan configuration

Using ArgoCD together with Kapitan is actually pretty easy and only requires the kapitan binary in the argo-repo-server and a ConfigManagement plugin in ArgocD (https://argoproj.github.io/argo-cd/user-guide/config-management-plugins/)

1. Edit argocd-cm configmap and add :

  configManagementPlugins: |
    - name: kapitan
      init:
        command: [sh]
        args: ["kapitan-base-compile.sh"]
