> In some cases, the AM may not be able to perform a readiness check for a
> container. For example, if a docker container is using a custom network type,
> its IP may not be reachable from the AM. In this case, the AM could request a
> new container to perform a readiness command, and use the exit status of the
> container to determine whether the readiness check succeeded or not.
