lotide installation

For production

Requirements: rustc, cargo, openssl, Migrant, and a PostgreSQL database

Set these environment variables:

• PGDATABASE, PGHOST, PGUSER, PGPASSWORD - Credentials for database connection, used by Migrant
• DATABASE_URL - Same credentials again, should be equivalent to postgres://$PGUSER:$PGPASSWORD@$PGHOST/$PGDATABASE. Used by lotide itself.
• HOST_URL_ACTIVITYPUB - If using the recommended proxy setup, set this to your root address (https://example.com)
• HOST_URL_API - e.g. https://example.com/api
• APUB_PROXY_REWRITES - Set to true to make signatures work with the proxy setup.
• BACKEND_HOST - (for hitide only) Set this to a URL which hitide can use to reach lotide

To build lotide, run cargo build --release in the lotide directory. A lotide binary will appear in ./target/release.

hitide can be built in the same way.

To set up the database, run migrant setup, then migrant apply -a.

Recommended proxy setup:

This is written for Nginx, but it should be possible to adapt it to other proxy servers. Replace c_backend_1 and c_hitide_1 with your actual hostnames.

location /api {
	proxy_pass http://c_backend_1:3333;
}
location /apub {
	proxy_pass http://c_backend_1:3333;
	proxy_set_header Host $host;
	proxy_set_header X-Forwarded-Path $request_uri;
}
location /.well-known {
	proxy_pass http://c_backend_1:3333;
}
location / {
	if ($http_accept ~* "application/activity\+json") {
		rewrite ^(.*)$ /apub$1;
	}
	if ($http_content_type = application/activity+json) {
		rewrite ^(.*)$ /apub$1;
	}
	proxy_pass http://c_hitide_1:4333;
}

For development

Requirements: rustc, cargo, openssl, Migrant, and a PostgreSQL database

The following environment variables are required (An environment variable manager like direnv is recommended in order to avoid these variables interfering with other programs.)

• PGDATABASE, PGHOST, PGUSER, PGPASSWORD - Credentials for database connection, used by Migrant
• DATABASE_URL - Same credentials again, should be equivalent to postgres://$PGUSER:$PGPASSWORD@$PGHOST/$PGDATABASE. Used by lotide itself.
• HOST_URL_ACTIVITYPUB - Typically http://localhost:3333/apub for dev instances
• HOST_URL_API - Typically http://localhost:3333/api for dev instances

Run migrant setup, then migrant apply -a to update the database schema.

To build and run lotide, run cargo run in the lotide directory.

Note that lotide itself does not contain a frontend, so you probably want to also setup hitide.
