Debug Argo workflow

Debug a pod#

To get into the container. Create YAML with command tail /dev/null to keep it running.

Example of test pod in tests/test-devnull-pod.yml:

apiVersion: v1
kind: Pod
metadata:
  labels:
    purpose: test
  name: test-devnull-pod
spec:
  volumes:
  - name: workdir
    hostPath:
      path: /data/d2s-workspace
      type: Directory
    # persistentVolumeClaim:
    #   claimName: d2s-storage
  containers:
  - name: test-devnull
    # Change the image to test here
    image: umids/rdfunit:latest
    command: [ "tail", "-f", "/dev/null"]
    resources:
      limits:
        cpu: 1000m 
        memory: 10Gi 
    volumeMounts:
    - name: workdir
      mountPath: /data

Then start the pod:

oc create -f tests/test-devnull-pod.yml

Connect with the Shell:

oc rsh test-devnull-pod

Debug an Argo workflow#

Pod can also be tested within an Argo workflow, see tests/test-devnull-argo.yml.
