> 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.
