I'm running a Docker container on MacOS that starts a Postgres server and MongoDB server as follows:

docker run -p 80:80 -p 27017:27017 dockertest
 * Starting PostgreSQL 9.3 database server
  ...done.
 * Starting database mongodb
  ...done.

The output shows that the MongoDB server is started correctly. Then I lookup the IP of the VM in which the container is running, like this:

docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER    ERRORS
default   *        virtualbox   Running   tcp://192.168.99.100:2376           v1.11.2

The ports seem to be mapped:

docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                          NAMES
39e5198e4693        dockertest   "/bin/sh -c 'service "   3 minutes ago       Up 3 minutes        0.0.0.0:80->80/tcp, 0.0.0.0:27017->27017/tcp   drunk_nobel

However, when I want to connect to the MongoDB in another terminal window, using

mongo 192.168.99.100:27017

I get the following error:

MongoDB shell version: 2.6.4
connecting to: 192.168.99.100:27017/test
2016-06-05T18:48:19.050+0200 warning: Failed to connect to      192.168.99.100:27017, reason: errno:61 Connection refused
2016-06-05T18:48:19.052+0200 Error: couldn't connect to server 192.168.99.100:27017 (192.168.99.100), connection attempt failed at    src/mongo/shell/mongo.js:148
exception: connect failed

I already had a look at similar questions (e.g., Unable to connect to mongoDB running in docker container) but the proposed solution does not seem to work.

  • Make sure that mongo container is mapped to port 27017. Try docker ps -a and inspect the port mapping Commented Jun 5, 2016 at 16:59
  • I did that, added the output of "docker ps" to the question. Commented Jun 5, 2016 at 17:02
  • ssh into the container and check if the mongo process is running. Commented Jun 6, 2016 at 1:17

The problem was not related to Docker, but to the bindip in the configuration of MongoDB. See e.g., mongodb.conf bind_ip = 127.0.0.1 does not work but 0.0.0.0 works

This exposes the db and it should be password protected then or use an ssh tunnel
