Add Docker support

[amcsi]

Cool project you have.

I helped Dockerize it for you.

I'd suggest you create an account on https://hub.docker.com/ for creating automated builds of the project, so users wouldn't have to build the project themselves. Also you could add yourself as the MAINTAINER of the Dockerfile which I left out, because I don't know your name/email ( like what I did in my project: https://github.com/amcsi/szeremi/blob/master/Dockerfile#L2 ).

Hey Attila, thanks for your contribution! It works like a charm. Found just some minor improvements. Other than that, I think this is good to go. 👍

• Add lib folder to .dockerignore, which is generated when you build the project locally

[amcsi]

Understood. I have made the commit with what you said and it seems to still work.

I'm still investigating how you can control Docker from within a container. I want to use your project to auto-pull and restart Docker containers with the help of Docker Hub webhooks, but I want to run hooka from within a container, because my server uses CoreOS where everything has to be in a container.

I was able to get docker ps to run within the container this way: docker run --rm -v ~/hooka/webhooks.json:/src/webhooks.json -p 3000:3000 --name hooka -v /var/run/docker.sock:/var/run/docker.sock -v /usr/bin/docker:/usr/bin/docker -v /lib/x86_64-linux-gnu:/lib/x86_64-linux-gnu -v /usr/lib/x86_64-linux-gnu/:/usr/lib/x86_64-linux-gnu/ hooka docker ps

I'm concerned of the last two lib mounts might be platform dependent, so I'm investigating a better way.

[danistefanovic]

I think there is no one-size-fits-all solution. I had to do this acrobatics to make it work under OSX with boot2docker:

docker run -v ~/Workspace/hooka/webhooks.json:/src/webhooks.json -v /usr/local/bin/docker:/usr/bin/docker -v $DOCKER_CERT_PATH:/certs -e "DOCKER_HOST=$DOCKER_HOST" -e "DOCKER_CERT_PATH=/certs" -e "DOCKER_TLS_VERIFY=1" hooka docker ps

[amcsi]

Oh crap i didnt realize i committed that change that removes the Expose command from the dockerfile. I think that command may be needed for things like random port binding to work

[danistefanovic]

No problem. I've fixed it d53b719
