'  --image=dummy --restart=Never

And working now. I went back through my notes but couldn't find what I had been doing wrong. I extended your example based on info found elsewhere to support using YAML as the override instead of JSON:

JSON=$(python -c 'import json,sys,yaml; y=yaml.safe_load(sys.stdin.read()); print(json.dumps(y))' <<EOF
spec:
  containers:
  - name: testcontainer
    image: ubuntu
  dnsPolicy: ClusterFirst
  volumes:
  - name: test
    persistentVolumeClaim:
      claimName: foo
  ...
EOF
)
oc -n namespace run test-pod --image=dummy --overrides=<<<"$JSON" --restart=Never

Thank you
