Recommended Project Structure for Docker

I’m working on a Go project that has the following structure (schematic):



  • Share SSH Key to Docker Machine
  • Docker bundle install cache issues when updating gems
  • Jackrabbit with PostgreSQL backend leaves repository in inconsistent state
  • How to generate a host unique ID?
  • Local development and swarm service image update
  • How can I use an ephemeral volume for a Docker container using an official MySQL image with docker-compose?
    • lib1 is a library
    • prog1 and prog2 are executables (both depend on lib1)

    In a nutshell: How do I create Dockerfiles for prog1 and prog2?

    I tried several approaches, all to no avail:

    Creating a Dockerfile in prog1/

    Failed because docker cannot ADD ../lib1 to the container since it is out of the context (see

    Creating a Dockerfile in the root directory

    Ignoring the fact that I actually need two Dockerfiles (for prog1, and for prog2), I tried placing the Dockerfile in the root directory of the project.

    However, the docker image I need to use (golang:1.4.1-onbuild) fails to find any Go files (since they are in ./prog1, and not in the root):

    + exec go install -v
    can't load package: package app: no buildable Go source files in /go/src/app

    What is the recommended project structure for the golang:1.4.1-onbuild image?

    Edit: Better asked here:

  • Wagtail Docker six package conflict on upgrade to wagtail 1.7
  • docker build fails on a cloud VM
  • Virtual machine, container shared CPU on Cloud
  • Can I run multiple programs in a Docker container?
  • How to properly set VOLUME and CMD instructions in Postgres Dockerfile?
  • Rails Atomicity problems?

    Most pull the files in via their VCS or just go get instead of using ADD. You add the the source tree in the same way regardless of what tool your building, since you need the structure of $GOPATH to be the same for each.

    Note, you can also name your docker file via docker build -f, so if you want to use ADD, you can have multiple DOCKERFILEs in your root directory.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
