How do I resolve hostnames to Docker containers from the host?

I understand Docker runs a magical dns on, so I figured I’d try

nslookup mycontainername

where mycontainername is, of course, the name of the container I’m trying to access. However, that timed out.

  • Can I pass arguments into docker-compose the command config option
  • DotNet build CLI works in terminal, but not in Docker build
  • How can I fix Docker/Mac no space left on device error?
  • Docker 1.12: Multiple replicas, single database
  • how to select options properly for “/bin/bash” when writing a blueprint for cloudify
  • Docker downloaded over 30 ubuntu images
  • ;; connection timed out; no servers could be reached

    What am I doing wrong? I’m on Docker 1.10.3. If it helps, I’m pulling up a bunch of containers using docker-compose 1.6.2.

    EDIT This is a duplicate of Docker 1.10 access a container by it's hostname from a host machine

    In the documentation it implies that this only works if you’ve explicitly created a network and attached the containers to them. Try something like:

    docker network create -d bridge --subnet isolated_nw
    docker network connect isolated_nw mycontainername

    And see if you can use (worked for me on version 1.10.3)

    For more information see this ticket.
