Configuration

For development, I recommend setting environment variables with direnv.

MIX_ENV=dev

In dev mode, Cannery will listen for these environment variables on compile.

• 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 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.
• ECTO_IPV6: Controls if Ecto should use ipv6 to connect to PostgreSQL. Defaults to false.
• POOL_SIZE: Controls the pool size to use with PostgreSQL. Defaults to 10.
• SECRET_KEY_BASE: Secret key base used to sign cookies. Must be generated with mix phx.gen.secret and set for server to start.
• REGISTRATION: Controls if user sign-up should be invite only or set to public. Set to public to enable public registration. Defaults to invite.
