# discworld
Docker build in any Docker container
This is useful for having containers with your build tools
and then creating a runtime container for your application
which is not polluted with the build tools and source code.
`alias itsWhalesAllTheWayDown='docker run -v /var/run/docker.sock:/var/run/docker.sock -v $(which docker):$(which docker) '`
Launch your builder and run bash.
`itsWhalesAllTheWayDown --rm -it -v $(pwd):/myapp myapp-builder /bin/bash`
Or if you have a build script as the ENTRYPOINT
`itsWhalesAllTheWayDown -d -v $(pwd):/myapp myapp-builder ...args to your script...`
Now run your docker commands from within the docker container you are running.
It will talk to the external docker-daemon and build your image externally.
Installation
----------------
Add the alias to your `.profile`, `.bash_profile`, or `.bashrc`
Minimal Golang Docker Image
---------------------------
`docker build -t golang-dockerizer .`
*this may be broken right now*
`alias itsGophersAllTheWayDown='itsWhalesAllTheWayDown -e "APPDIR=$(pwd)" -e "EXTERNAL_GOPATH=$GOPATH" -v $(pwd):$(pwd)) --rm -it golang-dockerizer'`
In your Golang project directory, create a Dockerfile like this:
```
FROM scratch
ADD GoappBinary /GoappBinary
ENTRYPOINT ["/GoappBinary"]
# include any other docker stuff you'd like
# ADD src/www /www
# EXPOSE 8080
# VOLUME /path/to/dir
```
Then run
`itsGophersAllTheWayDown `
This will produce a Docker image with just your Golang app.
