Hey @teamsmiley. Yes, you can. The same waitdaemon image you have above for kexec can be used. See the waitdaemon doc for more details. https://github.com/jacobweinstock/waitdaemon

- name: "reboot"
  image: ghcr.io/jacobweinstock/waitdaemon:latest
  timeout: 60
  pid: host
  command: ["reboot"]
  environment:
    IMAGE: alpine
    WAIT_SECONDS: 5
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
