@ -367,7 +367,10 @@ Environment Variable: WATCHTOWER_WARN_ON_HEAD_FAILURE
## Health check
Run health check and exit.
Returns a success exit code to enable usage with docker `HEALTHCHECK`. This check is naive and only returns checks whether there is another process running inside the container, as it is the only known form of failure state for watchtowers container.
!!! note "Only for HEALTHCHECK use"
Never put this on the main container executable command line as it is only meant to be run from docker HEALTHCHECK.
