This commit makes it possible to override settings during tests, by
switching capsulflask/__init__.py to a "create_app" pattern, and using
`dotenv_values` instead of `load_dotenv`.
The create_app() method returns a Flask app instance, to give
more control over when to initialise the app. This allows setting
environment variables in test files.
Then, use dotenv_values to override loaded .env variables with ones from
the environment, so that tests can set `POSTGRES_CONNECTION_PARAMETERS`
and `SPOKE_MODEL` (possibly others in future..).
Inital tests for the "landing" pages, and login / activation, are
included.
The shell script which gets informations from libvirt incorrectly
matches virsh output lines which contain VMs' public IPv4 addresses.
It doesn't work when there are multiple address families which breaks
reporting of IPv4 address when a VM also has an IPv6 address and virsh
happen to output that one first.
This commit changes it to explicitely match the first ipv4 address instead.
Adds:
- a Docker image, which can be used in both development and production
- a `docker-compose.yml` file for local development (could probably be adapted for production deployments)
Testing:
- `git checkout docker`
- `docker-compose up`
- pray 🙏
- go to http://localhost:5000
## App architecture
I added the ability to load secret config variables (`HUB_TOKEN`, `STRIPE_SECRET_KEY` etc) from files, to support [Docker Secrets](https://docs.docker.com/engine/swarm/secrets/) natively. The code should probably log an error if a specified `HUB_TOKEN_FILE` doesn't exist instead of failing silently..
## Docker architecture
This uses a multi-stage build to reduce the size of the final image -- having pipenv install to a predefined virtualenv, and then copying that over.
The compose file doesn't include a definition for a cron runner service, and I haven't tested running one yet. Here be dragons!
You can rebuild the image locally using `docker-compose build`, but this isn't required for changes to the app code, only if you edit the `Dockerfile`, or want to publish your image for use on a swarm server (in which case you will need to edit the image name to put in your own Docker hub credentials).
Currently, the image is rebuilt (should set up auto-tagging..) and published with every push to this 3wordchant/capsul-flask fork.

Specify `THEME=yourtheme`, add some HTML files in `capsulflask/theme/yourtheme` 👌
We probably want to reduce copypasta in the current `yolocolo` theme by using template inheritance, at some point.

create.sh will now be passed two extra arguments from the web app:
network_name and public_ipv4_address
network_name will be virbr1 or virbr2 or whatever the network is called
and public_ipv4_address will be an ipv4 from that network which is not
currently being used
