How to restore home assistant on k8s
  1. Deploy new home asssiant
  2. Edit deployment and add custom command: `command: ["sleep", "infinity"]
  3. Exec onto sleeping pod and delete everything in config dir. eg: k exec -n homeassistant home-assistant-xxx -it /bin/sh`
  4. Use kubectl cp to copy unzipped backup into place: k cp -n homeassistant . home-assistant-xxx:/config You may have to hurry as the pod will be restarted as it will be failing its liveliness tests.
  5. Edit the deployment again to remove the sleep command
  6. Breathe
