Docker-Registry

Create the configuration

cp config_sample.yml config.yml

Edit the configuration with your information.

Each key in the configuration (except "common") is flavor. You can specify the flavor by setting the environment variable "SETTINGS_FLAVOR". If there is no variable set, the default one is "dev".

Run the Registry

Install the system requirements for building a Python library:

sudo apt-get install build-essential libpython-dev libevent-dev

Then install the Registry app:

pip install -r requirements.txt

And run it (for a dev environment):

gunicorn --access-logfile - --debug -k gevent -b 0.0.0.0:5000 -w 1 wsgi:application

The recommended setting to run the Registry in a prod environment is gunicorn behind a nginx server which supports chunked transfer-encoding (nginx >= 1.3.9).

You could use for instance supervisord to spawn the Registry using this command:

gunicorn -k gevent --max-requests 100 --graceful-timeout 3600 -t 3600 -b localhost:5000 -w 8 wsgi:application

The nginx configuration will look like:

location / {
  proxy_pass        http://localhost:5000;
  proxy_set_header  X-Real-IP  $remote_addr;
}

And you might want to add Basic auth on Nginx to protect it (if you're not using it on your local network):

Run tests

$ cd test
$ python -m unittest discover

The file workflow.py is bit special since it's a functional test (not a unit test). It requires a server to be running in order to succeed.

$ DOCKER_CREDS="user:password" python -m unittest workflow

DOCKER_CREDS contains user credentials information to connect to the staging index server.

How to contribute

If you want to submit a pull request, an important point is to clear up all flake8 warning you could introduce (ignore the one about registry/init.py).

$ pip install flake8
$ find . -name '*.py' -exec flake8 {} \;
