I am using Docker version 17.09.0-ce, and I see that containers are marked as unhealthy. Is there an option to get the container restart instead of keeping the container as unhealthy?

Restarting of unhealty container feature was in the original PR (https://github.com/moby/moby/pull/22719), but was removed after a discussion and considered to be done later as enhancement of RestartPolicy.

At this moment you can use this workaround to automatically restarting unhealty containers: https://hub.docker.com/r/willfarrell/autoheal/

Here is a sample compose file:

version: '2'
services:
  autoheal:
    restart: always
    image: willfarrell/autoheal
    environment:
      - AUTOHEAL_CONTAINER_LABEL=all
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

Simply execute docker-compose up -d on this
