> 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.
