Matt Heon 482ef7bfcf Add support for updating restart policy
This is something Docker does, and we did not do until now. Most
difficult/annoying part was the REST API, where I did not really
want to modify the struct being sent, so I made the new restart
policy parameters query parameters instead.

Testing was also a bit annoying, because testing restart policy
always is.

--restart=policy

Restart policy to follow when containers exit. Restart policy does not take effect if a container is stopped via the podman kill or podman stop commands.

Valid policy values are:

  • no : Do not restart containers on exit
  • never : Synonym for no; do not restart containers on exit
  • on-failure[:max_retries] : Restart containers when they exit with a non-zero exit code, retrying indefinitely or until the optional max_retries count is hit
  • always : Restart containers when they exit, regardless of status, retrying indefinitely
  • unless-stopped : Identical to always

Podman provides a systemd unit file, podman-restart.service, which restarts containers after a system reboot.

When running containers in systemd services, use the restart functionality provided by systemd. In other words, do not use this option in a container unit, instead set the Restart= systemd directive in the [Service] section. See podman-systemd.unit(5) and systemd.service(5).
