+#### **--health-on-failure**=*action*
+
+Action to take once the container transitions to an unhealthy state. The default is **none**.
+
+- **none**: Take no action.
+- **kill**: Kill the container.
+- **restart**: Restart the container. Do not combine the `restart` action with the `--restart` flag. When running inside of a systemd unit, consider using the `kill` or `stop` action instead to make use of systemd's restart policy.
+- **stop**: Stop the container.
