Docker Toolbox for Windows and Windows Subsystem for Linux (aka Bash on Windows)

# This script installs and configures WSL to work with Docker Toolbox for Windows.
# 1. Install WSL (check out [bowinstaller](https://github.com/xezpeleta/bowinstaller) for programmatic installation.
# 2. Run the contents of this script in Bash. (copy and paste works fine, no need to save)

@EzeRangel, what do you mean by "the commands" and "do nothing". After running this are you able to run operations like docker ps?

@EzeRangel, I just realized that I had omitted a critical part of matching up WSL to work with Docker Toolbox for Windows. I have now added that part (lines 27 and 28) and this will hopefully work for you now.

Does anyone have an idea how to package this to better be distributed? Could we somehow wrap the docker command in WSL to automatically start docker-machine if it's not already running? Could we distribute via a single command like 'curl https://thisscript.sh | bash'? How can we avoid cluttering .bashrc?

Works well. Thanks

The docker-machine + sed command (line 25) to grab and set variable seems to break on User directory names that have spaces. This monstrosity (below) seems to handle spaces better, but I'm sure there's a better way to do it.

arr=$(./docker-machine.exe env --shell bash | sed 's/C:/\/c/' | sed 's/\\/\//g' | sed 's:#.*$::g' | sed 's/"/\x27/g')
readarray -t y <<<"$arr"
for ((i=0; i< ${#y[@]}; i++)); do eval "${y[$i]}"; done

For some reason, when I use docker-compose, mounted volumes start with path "/mnt/c/", instead of "/c/", causing the volume to be improperly mounted (I think). Does anyone know a fix for this?

Here's my docker-compose.yml:

web:
    image: nginx:latest
    ports:
        - "8080:80"
    volumes:
        - ./code:/code
        - ./site.conf:/etc/nginx/conf.d/site.conf

web_1  | 2017/10/12 13:17:08 [crit] 1#1: pread() "/etc/nginx/conf.d/site.conf" failed (21: Is a directory)
web_1  | nginx: [crit] pread() "/etc/nginx/conf.d/site.conf" failed (21: Is a directory)

When using PowerShell, everything works fine.

Getting
Could not read CA certificate "/home/schenkj/.docker/ca.pem": open /home/schenkj/.docker/ca.pem: no such file or directory when running docker ps on WSL.

This is great! This might be a newb question, but how do I handle this?

$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Update... I'm now up and running thanks to this script as well as this gist, and possibly another link I can't find right now.

I think these are all the steps that got me the rest of the way:

I added these to .bashrc (.zshrc in my case):

export DOCKER_TLS_VERIFY=0                                         
export DOCKER_HOST=tcp://$(cd /mnt/c && docker-machine.exe ip):2376

Then back in my terminal I ran these commands:

docker-machine.exe restart default
mkdir -p ~/.docker
ln -s /mnt/c/Users/John/.docker/machine/certs/ca.pem ~/.docker/ca.pem
ln -s /mnt/c/Users/John/.docker/machine/certs/ca-key.pem ~/.docker/ca-key.pem
ln -s /mnt/c/Users/John/.docker/machine/certs/cert.pem ~/.docker/cert.pem
ln -s /mnt/c/Users/John/.docker/machine/certs/key.pem ~/.docker/key.pem
docker-machine.exe upgrade

Finally I followed these instructions to get my DNS setup to use google's 8.8.8.8 and 8.8.8.4.

There is a nice docker-env wrapper script that does the ENV/export conversion (well enough, had no issues yet):

I made a similar HOWTO (though inferior to this approach I think), maybe it is still helpful for you for fixing some other issues:
https://gist.github.com/strarsis/44ded0d254066d9cb125ebbb04650d6c

I am also having trouble with volumes. The files are missing when using docker-compose up. Example:

version: '3'
services:
  myservice:
    image: some/image
    build .
    volumes:
     - .:/usr/my-service
     - /usr/my-service/node_modules

Example Dockerfile:

FROM node:8.9.4-alpine

ENV HOME=/usr/my-service
RUN mkdir -p $HOME
WORKDIR $HOME

ADD package.json $HOME
ADD package-lock.json $HOME

RUN npm install --silent

ADD . $HOME

EXPOSE 8080

CMD npm run start:docker

Any ideas? /cc @fishnux @strarsis @jwilson8767

A recent commit in docker toolbox breaks this. Two changes in this commit are problematic.

1. They no longer hard-code the docker toolbox and docker-machine.exe paths. Simple fix is to do export DOCKER_TOOLBOX_INSTALL_PATH='/c/Program Files/Docker Toolbox' before calling ./start.sh exit.
2. On line 80 of the commit, they convert the exports to SETX syntax, which won't work in wsl. Not sure of a good fix for this. Personally, I just deleted the line from my start.sh, but I'd rather have a fix in my .bashrc without touching start.sh.

Unfortunately, start.sh uses a windows path to docker-machine.exe. I fixed it locally to use which to find the executable but then that exposed another issue: you cannot run docker-machine.exe commands without the variables set by docker-machine.exe --shell bash. So you can't run the command that sets the variables that you need to run the command.

source <(docker-machine.exe env default --shell bash | sed 's?\\?/?g;s?C:/?/mnt/c/?g') run this before docker-compose.
