OOD and Kubernetes (k8s)

So for the testing my group is doing, we have setup a test k8s cluster using microk8s. The kubernetes setup is hosted on a different machine than the machine OOD is on. We have confirmed that the OOD system can talk to the k8s setup via the kube API. Based on the corresponding page in the docs, I’ve setup the following file ‘k8s.yml’ in the '/etc/ood/config/clusters.d/k8s.yml`

v2:
  metada:
    title: "K8s"
  login:
    host: "192.168.7.254"
  job:
    adapter: "kubernetes"
    config_file: "/home/ubuntu/kubeconfig"
    cluster: "k8s"
    context: "k8s"
    bin: "/bin/kubectl"
    username_prefix: ""
    namespace_prefix: ""
    all_namespaces: false
    auto_supplemental_groups: false
    server:
      endpoint: "https://192.168.7.254:16443"
#      cert_authority_file: "/etc/pki/tls/certs/kubernetes-ca.crt"
    auth:
      type: "oidc"
    mounts: []
  batch_connect:
    ssh_allow: true
    header: "#!/bin/bash"

I don’t immediately see anything that would cause this setup to not work, but I was hoping someone could shed some more light on the various components of the cluster configuration file and clarify if the bootstrapping steps are necessary to run. If so, I assume the VERSION I need is equal to the server/client version from kubectl version. Additionally, if simply clicking the ‘shell access’ button won’t prove if things are working properly, I’d be happy to know another way to test that OOD is able to use k8s properly.

I’m not sure where you are in testing? I’d guess you need to create an application that can use the cluster and start testing that application. Maybe start with a simple static page and/or a super simple Juypter installation.

Sure, I’ll look into the tutorial for a k8s app and see how that goes.

That worked like a charm to start getting error messages to debug. I’ll hammer away for a bit and see what I can figure out and solve myself. Thanks for the help.
