Re-build Go (App Engine) app running inside docker container?

Normally, when you run a Go app using Go-Appengine’s goapp serve command, file changes are detected and initiate a re-build.

INFO     2015-01-11 ... Detected file changes: ...

I’m currently experimenting with running Go-Appengine inside a docker container, and while the server starts appropriately, file changes do not initiate a re-build. How do I make this happen?

  • Issues accessing Sinatra app in Docker container
  • Dockerfile CMD script runs differently to running script manually in container
  • How to prevent database docker from being rebuilt and losing production data
  • Integrate Grunt in docker-compose?
  • unable to run a container with volume on glusterfs
  • How to _directly_ COPY files to “Program Files (x86)” folder in a Windows container?
  • From my personal experience, Django projects running inside and outside docker containers behave the same way when file changes are detected.

  • Can't access mounted volume in docker
  • .NET Core 1.1, Docker Build encounters Couldn't find 'project.json' with csproj
  • Will istio add support for docker swarm?
  • Tomcat freezes in Docker container when starting
  • Multi command with docker in a script
  • How to get exact date for docker images?

    I think the problem here is that the files don’t change inside the docker-container, only on the host-filesystem. Your source-directory is added in the Dockerfile (when the container-image is built). If you change the files later, the container is not automatically rebuilt.

    To solve this issue (for development-purposes) you could mount the source-directory from your host-system into the docker-container. with this trick, source-changes are automatically added to the container.

    To to this, add

    volumes:
      - .:/go/src
    
    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
