flynn-dev-docker

Provides an environment to run the flynn development code within a docker container. Source directories are shared between the host and the docker container.

Configuration

1. The prebuilt docker (step 1 below) container sets GOPATH to /root/flynn. The host machines GOPATH directory should be shared as a volume with the container.
2. The container is given the hostname flynn.

Steps to run

1. docker pull sidkurias/flynn-dev-docker.
   This will pull the prebuilt image to run a 'docker in docker' env that works with flynn.
2. Run the container.
   docker run -h flynn -privileged -v GOPATH on HOST:/root/flynn -i -t sidkurias/flynn-dev-docker
3. cd /root/flynn
4. go get github.com/sid-kurias/flynn-dev-docker
5. cd src/github.com/sid-kurias/flynn-dev-docker
6. Edit the Procfile. Change the ip address that lorne and shelf need to the ip address of the container's eth0 interface. This can be obtained by executing:
   ip addr show
7. make
8. cd nodejs-example
9. git push flynn master
10. Once the build is complete execute
    curl http://IPADDR:55000 (addr is got from step 6)

Steps to build the docker image yourself

Prerequisites

1. Docker is installed
2. godeb is installed
   wget -O godeb.tar.gz https://godeb.s3.amazonaws.com/godeb-amd64.tar.gz
   tar -zxvf godeb.tar.gz
3. The godeb, docker and wrapdocker binaries should be in the same directory as the Dockerfile.
4. docker build -t 'YOUR TAG NAME' .
