I am trying to connect to docker mongo image in my local windows machine, I installed mongodb in local, and added the mongodb bin path to windows path environment variable. And I am doing below steps

cd <docker-location>

docker login

docker ps

-- to check already mongo running

docker pull myrepo/mymongo-image:1.0
docker run -p 27017:27017 -d --net=host --name=mytestDB myrepo/mymongo-image:1.0

docker logs mytestDB 

Output: MongoDB starting : pid=6 port=27017 dbpath=/data/db 64-bit host=moby docker ps Output:

CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS               NAMES

start mongo in local:

mongo --port 27017

But I am getting error like this:

MongoDB shell version: 3.2.1
connecting to:
2016-10-13T20:04:12.273+0530 W NETWORK  [thread1] Failed to connect to, reason: errno:10061 No connection could be made because the target machine actively refused it.
2016-10-13T20:04:12.277+0530 E QUERY    [thread1] Error: couldn't connect to server, connection attempt failed :

Please let me know where I did mistake.


Don't use --net=host. It looks like you are asking docker to publish the port since you have supplied the -p 27017:27017 option, but --net=host asks Docker to turn off all network isolation features, including port publishing.

Docker-for-windows sets up a little VM in hyperv where Docker runs. Your --net=host container ends up listening on that VM's interfaces. The Docker-for-windows network port forwarding pays attention only to published ports, so that's why no forwarding is happening.

If your run that same command without --net=host, you should get a different result.

Sometimes, if you try to run a containerized process and the published port doesn't seem to be working, it is because the process is listening on the container's lo0 interface and not the eth0 interface.

Here's a good benchmark test container to run to test out publishing ports:

docker run --name testweb -d -p 8989:80 nginx:alpine

You should then be able to connect to and see an nginx welcome page.
