# Features
- User Registration/Sign in via `phx_gen_auth`
- `Dockerfile` and example `docker-compose.yml`
- Automatic migrations in `MIX_ENV=prod` or Docker image
- JS linting with [standard.js](https://standardjs.com), HEEx linting with
[heex_formatter](https://github.com/feliperenan/heex_formatter)
- Customizable invite tokens or public registration via `REGISTRATION`
- Create containers to store your ammunition, and tag them with custom tags
- Add ammunition types to Cannery, and then ammunition to your containers
- Customizable invite tokens or public registration via the `REGISTRATION`
environment variable.
# Installation
1. Install [Docker Compose](https://docs.docker.com/compose/install/) or alternatively [Docker Desktop](https://docs.docker.com/desktop/) on your machine.
1. Copy the example `docker-compose.yml` into your local machine where you want
1. Copy the example `docker-compose.yml` into your local machine where you want.
Bind mounts are created in the same directory by default.
1. Use `docker-compose up` or `docker-compose up -d` to start the container.
# Local Development
## Reverse proxy
1. Clone the repo
2. Run `mix setup`
3. Run `mix phx.server` to start the development server
Finally, reverse proxy to port `80` of the container. If you're using a reverse proxy in another docker container, you can reverse proxy to `http://cannery:80`. Otherwise, you'll need to modify the `docker-compose.yml` to bind the port to your local machine.
For instance, instead of
```
expose:
- "80"
```
use
```
ports:
- "127.0.0.1:80:80"
```
and reverse proxy to `http://localhost:80`.
# Configuration
For development, I recommend setting environment variables with [direnv](https://direnv.net).
## `MIX_ENV=dev`
In `dev` mode, Cannery will listen for these environment variables on compile.
You can use the following environment variables to configure Cannery in
`docker-compose.yml`.
- `HOST`: External url to generate links with. Set these especially if you're
behind a reverse proxy. Defaults to `localhost`.
- `PORT`: External port for urls. Defaults to `443`.
- `DATABASE_URL`: Controls the database url to connect to. Defaults to
`ecto://postgres:postgres@localhost/cannery_dev`.
- `REGISTRATION`: Controls if user sign-up should be invite only or set to public. Set to `public` to enable public registration. Defaults to `invite`.
## `MIX_ENV=prod`
In `prod` mode (or in the Docker container), Cannery will listen for these environment variables at runtime.
- `HOST`: External url to generate links with. Set these especially if you're
behind a reverse proxy. Defaults to `localhost`.
- `PORT`: Internal port to bind to. Defaults to `4000` and attempts to bind to
- `PORT`: Internal port to bind to. Defaults to `80` and attempts to bind to
`0.0.0.0`. Must be reverse proxied!
- `DATABASE_URL`: Controls the database url to connect to. Defaults to
`ecto://postgres:postgres@cannery-db/cannery`.
