Working with Docker under Windows becomes easier and easier. I am often ask by co-workers how to run Docker behind a firewall, this blog gives a little recipe, how to set up the whole Windows/Docker/Firewall environment.

1. Install Virtual Box
2. Download Docker Machine to manage your docker hosts
   • You find the Windows versions (32 and 64 bit) at above link
   • Rename the exe to docker-machine.exe
   • I would recommend putting the machine in a dedicated docker directory and update your PATH env variable
3. Install the Docker Windows client
   • You find it at https://get.docker.com/builds/Windows/x86_64/docker-latest.exe for 64 bit
   • Or https://get.docker.com/builds/Windows/i386/docker-latest.exe for 32 bit
   • Rename  it to docker.exe and put it in the directory where you put the machine
4. Create a Docker host named ‘dev’ with docker machine
   • docker-machine create --driver virtualbox dev
5. Connect the Docker client with the docker vm
   • Saving the environment to a .bat file: docker-machine env -shell cmd dev > docker-env.bat
   • You will get something like
     SET DOCKER_TLS_VERIFY=1
     SET DOCKER_HOST=tcp://192.168.99.2:2376
     SET DOCKER_CERT_PATH=C:\Users\toedter_k\.docker\machine\machines\dev
     SET DOCKER_MACHINE_NAME=dev
     REM Run this command to configure your shell:
     REM FOR /f “tokens=*” %i IN (‘docker-machine env -shell cmd dev’) DO %i
   • Run the bat file (or, like docker-machine tells you, you could run the code in the last line without the REM 🙂 )
   • Check if the client is working:
     • Run docker ps in a Windows cmd
6. Prepare the proxy settings
   • SSH into the docker dev host: docker-machine ssh dev
   • Add the following lines to /var/lib/boot2docker/profile (this file is read-only, use sudo)
     export HTTP_PROXY=http://<proxy>:<port>
     export HTTPS_PROXY=http://<proxy>:<port>
   • Exit the ssh session and restart the docker machine: docker-machine restart dev

Now you should be able to use Docker on Windows behind a firewall. To test it, open a Windows cmd and run
docker run busybox echo hello world

After docker has downloaded the busybox image you should see

hello world

That’s it 🙂
Now you can easily use all Eclipse or IntelliJ IDEA plugins that require a local Docker installation.
