Make a dockerfile to setup hook.io environment

[siuying]

The aim is finish the Dockerfile and docker-compose setup and make it one command deployable. It is not yet finished.

[Marak]

Seems like a good start.

Once you are able to get the Docker image going from zero to started, let me know and we can try to merge these changes.

[siuying]

Added a setup image in docker-compose to run the setup script ... now basic server can be started:

docker-compose run setup
docker-compose up

But they throw a lot of error like this:

worker_1 | (node) warning: possible EventEmitter memory leak detected. 21 listeners added. Use emitter.setMaxListeners() to increase limit.

had no idea what they mean.

@siuying -

Those are warning and can be ignored.

Did you try accessing the http services after starting?

I tried running docker-compose run setup, and got the following error:

Any ideas?

Okay. Made a bit of progress.

The build error is related to existing node_modules/ folder and cross-system env issue. npm is to blame for that one. rm -rf node_modules/ before building fixes that issue.

Almost got it working now but last command is hanging....going to double check a few things.

Starting hookio_redis_1...
Starting hookio_couch_1...
Starting hookio_worker_1...
Starting hookio_hookio_1...
Starting hookio_setup_1...
Attaching to 

[Marak]

Updated docker locally and made a few more changes.

Currently stuck at getting the admin user connected and configured for couch.

[Marak]

So I've mostly got the Dockerized version of the app working.

Currently the app will load, users can signup and create hooks, hooks can be run.

What is not working is a lot of the redirects and similar items related to knowing the ip address of the docker-machine. You would think that using link and creating a host would be sufficient, but it's not.

Certain parts of the app need to know the IP of the machine. I can solve this locally by modifying the hosts file on my computer ( not the docker machine ) to point to the ip address docker-machine ip returns, but that somewhat defeats the purpose of making a friendly portable Dockerfile.

I have a solution, but it will require I allow for dynamic configuration of hook.io's config.js file after process start. I can then send a command to the app to update the config.baseUrl variable based on the first entry of the docker hosts file.

awk 'NR==1 {print $1}' /etc/hosts

None of this is ideal, I don't see another way around it.

[Marak]

Docker is mostly working now.

I added a special admin route that must be hit after starting the app in order to update the IP address inside app.

Documentation is in the README.
