In 1.7 I am able to do the following:

```
 healthcheck:
   test: wget -q --spider http://localhost:8080/ping

```

But in 2.0 I can't find the command to run.

I saw that before. when I run that command using `docker exec [containerid] traefik healtcheck`

> OCI runtime exec failed: exec failed: container\_linux.go:345: starting container process caused "exec: "traefik": executable file not found in $PATH": unknown

In addition it never returns healthy.

Neither does `healthcheck` alone

> OCI runtime exec failed: exec failed: container\_linux.go:345: starting container process caused "exec: "healtcheck": executable file not found in $PATH": unknown

Tthe command `healtcheck` is a standalone command:

```auto
docker run traefik:v2.0.0-rc2 healthcheck
docker run traefik:v1.7.14 healthcheck

```

and the binary is not in the PATH:

```auto
docker exec f1dda0094a5f ./traefik healthcheck

```

The documentation left out the `./` and it needs the `--ping` to be specified

```
docker exec 48d286711eae ./traefik healthcheck --ping

```

> time="2019-09-05T11:13:31Z" level=info msg="Configuration loaded from flags."  
> OK: http://:8080/ping

also healthcheck ignores any attempts to disable logging, so `--log=false` or `--log.level=ERROR` still displays the message

So the final solution you would think at the moment is the following in the docker-compose.yml file.

```auto
    healthcheck:
      test: ./traefik healtcheck --ping 

```

However, when adding that, it terminates traefik.

This appears to be working in the GA release using the following

```
healthcheck:
  test: traefik healthcheck --ping

```

I have incorporated it in [Trajano base Docker swarm stacks](https://community.containo.us/t/trajano-base-docker-swarm-stacks/1899)

I fully agree that the docs could be improved. The current docs ([of CLI](https://docs.traefik.io/operations/cli/)) made me interpret it as a command available on the host.

```auto
root@Ubuntu18:~# traefik healthcheck --ping
traefik: command not found

```

so reading this here eventually enlightened me, so I did  
`docker exec [container name] traefik healtcheck --ping`  
what results in

```auto
root@Ubuntu18:~# docker exec -it traefik traefik healthcheck --ping
INFO[0000] Configuration loaded from flags.
Bad healthcheck status: 404 Not Found

```

I found a discussion on this result in [Strange healthcheck behaviour](https://community.containo.us/t/strange-healthcheck-behaviour/2957) but I still don't get it.

I used the -t flag to make the output to look a bit prettier. See [docker exec | Docker Documentation](https://docs.docker.com/engine/reference/commandline/exec/) for more details on the flags.
