Seems like you have multiple issues:

  1. For some reason zookeeper is not reachable. This one looks like a DNS issue. docker-compose handles this automatically so don’t really know what’s going on there
  2. I guess you were trying to upgrade from a 9.1.2 installation which uses Postgres 9.5 and the automatic upgrade to Postgres 9.6 failed. You’d need to inspect the install logs to figure out what went wrong there.
