Added Docker setup.

[jezdez]

This adds:

• a Dockerfile
• a Docker compose file for easy testing
• a Travis CI setup
  • so that it can build a Docker image and push to Docker Hub automatically
  • it does that on every Git tag as well and push a equally tagged version to Docker Hub
• extends the Makefile to add some helper tasks for docker (e.g. make docker-test)

Fix #80

@yohanboniface

• Could you please take a look at the settings file and if that's the env var names you like? Any settings missing?

Also, there are a few assumptions I've made:

• you'd have to enable Travis CI for the repo: https://travis-ci.org/

• sign up for Docker Hub and let me know the username so I can set the DOCKER_IMAGE_NAME env var name in the .travis.yml accordingly, as it consists of the username and project name you chose for uMap

• in addition you'll have to provide your Docker username and password to the Travis CI project settings as DOCKER_USERNAME and DOCKER_PASSWORD (don't paste them into .travis.yml)

sign up for Docker Hub and let me know the username so I can set the DOCKER_IMAGE_NAME env var name in the .travis.yml accordingly, as it consists of the username and project name you chose for uMap

My username is "yohanboniface". I've also added "umap" as organisation, and you as this organisation maintainer.

in addition you'll have to provide your Docker username and password to the Travis CI project settings as DOCKER_USERNAME and DOCKER_PASSWORD (don't paste them into .travis.yml)

No way to add in encrypted in the travis.yml?

[yohanboniface]

I'd suggest to keep in docker.py only the specific bits, so I'd move the env sniffing in base.py. Appart from the new depss, it does not hurt, and may even save someone's day :)

[yohanboniface]

Shouldn't we create the psql db to be able to run tests?

[yohanboniface]

Out of scope for this PR, but someone may want to run uMap with another OAuth provider. Not sure how to make this easy/possible with Docker.

Hello,
What is the status of this PR ?
I would be interested in this functionality, and it seems quit advanced :)

[jezdez]

Ugh, I forgot I did this, not sure. @yohanboniface Do you still want/need this?

[yohanboniface]

A uMap Docker image would of course be awesome!

But I'm missing Docker habits myself and time to join the effort. Mainly, I've bad (old) experience with data management when updating a docker image.

I'll try to have a deeper look anyway.

[xthursdayx]

I'm super interested in this as well. I had tried to figure out how to create a docker container of uMap myself, but the limits of my technical capacity quickly became apparent.

[drunkod]

I support it.
  It speeds up development!

Please merge! :-)

@yohanboniface @jezdez Any advance on this PR?

If you specify what does it lack to be able to be merged into master I may be able to help.

[jezdez]

No idea, I’m sorry, I haven’t had time to look into it and don’t have a need for it anymore.

[Duvel]

Maybe it could be an idea to split the travis part from the docker part and add that later?

@yohanboniface did add some comments, but I think that these also can be resolved later.

One of the things currently missing in the docker container is correct logging. I have version 0.8.2 running in docker, but version 1.1.2 is giving errors and I have no clue why, because of missing logging.

[Duvel]

I got logging working in my test now, thanks to docker.py in msgre/uwsgi_logging@4055e52.

So probably that is something we would want to add.

[Fi1osof]

Did try this. Many errors. Sad :(
@jezdez, thanks for trying!

[Duvel]

@Fi1osof I updated my fork with the files, that I used to get a working docker image. It is based on the work done by @jezdez and I updated it for the newer versions of uMap. I added a pull request #801 if we would like to have this as part of this project.

[jezdez]

Closing in favor of #801.
