Running via Docker

Use the provided Dockerfile, supplying the following environment variables:

  • SITE_DOMAIN: the domain this will be hosted at, without the protocol. Example: journal.example.com.
  • DATABASE_URL: URL of a PostgreSQL database for the application to use. Example: postgres:https://journal:[email protected]/journal.
  • CIPHER_KEY: Secret key used in encrypting. It needs to be 32 bytes base 64 encoded. Generate with Base64.encode64(SecureRandom.random_bytes(32)).
  • SHARING_TOKEN_CIPHER_IV: This is to make sure sharing token IVs are the same so we can find posts from a public route parameter. It needs to be 16 bytes base 64 encoded. Generate with Base64.encode64(SecureRandom.random_bytes(16)).
  • SECRET_KEY_BASE: Secret key for verifying the integrity of signed cookies. Generate with SecureRandom.alphanumeric(30).

The initial user with username admin will be created on application start if there are no existing users in the database. The password will be printed to the standard output.

The container expects to be proxied to its real address. Here is example proxy configuration for nginx if the container is listening on port 12345 and nginx is terminating the HTTPS connection:

location / {
  proxy_pass https://localhost:12345;

  proxy_set_header Host $http_host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto $scheme;
  proxy_set_header X-Forwarded-Ssl on;
  proxy_set_header X-Forwarded-Port $server_port;
  proxy_set_header X-Forwarded-Host $http_host;
}
