CodePudding user response：

Try this

kubectl patch deployment xxxx --type='json' -p='[{"op": "replace", "path": "/spec/template/spec/containers/0/command", "value": ["argocd-server", "--insecure"]}]'

and verify the command

kubectl get deployment xxxx  -o=json | jq '.spec.template.spec.containers[0].command'

output

[
  "argocd-server",
  "--insecure"
]
