jelmer / redirect-webfinger

Simple webfinger redirect implementation (to e.g. another Mastodon server)

Simple redirecting webfinger implementation

This simple webfinger implementation just redirects a single webfinger address to another server. I use it to allow people to find my mastodon profile via my personal server.

Example usage:

$ redirect-webfinger [email protected] \
     --mastodon-server=mastodon.cloud \
     --mastodon-user=jelmer

The only URL it exposes is /.well-known/webfinger, which you would probably want to expose via your reverse HTTP proxy.

Or using docker/podman:

$ podman run ghcr.io/jelmer/redirect-webfinger \
     -e [email protected] \
     -e MASTODON_SERVER=mastodon.cloud \
     -e MASTODON_USER=jelmer

redirect-webfinger's Issues

argparse nargs=1 actually generates a single-element list

From my local testing, I couldn't get the webfinger endpoint to match properly.

I think parser.add_argument(..., nargs=1, ...) actually causes args.acct (etc.) to be single-element lists, so then app['acct'] becomes e.g. ['[email protected]'] rather than '[email protected]' so then the supported_resource check never matches.

Does not appear to pick up environment variables running on Docker on WSL

It throws this error with the correct account specified:

WARNING:root:Unknown resource: 'acct:[email protected]'

When started with

docker run --name webfinger -p 8080:8080 -e [email protected] -e MASTODON_SERVER=mastodon.social -e MASTODON_USER=user ghcr.io/jelmer/redirect-webfinger:latest

If started with

docker run --name webfinger -p 8080:8080 ghcr.io/jelmer/redirect-webfinger:latest [email protected] --mastodon-server=mastodon.social --mastodon-user=user

It correctly returns the expected JSON response.

It looks like it is failing to pick up the environment variable as specified at https://github.com/jelmer/redirect-webfinger/blob/main/redirect_webfinger/__main__.py#L39

    parser.add_argument(
        '--acct', type=str, help='Example: [email protected]', nargs='*',
        default=os.environ.get('ACCT'))

I confirmed that the environment variables were correctly set.

Docker Desktop 4.13.1 on Ubuntu 22.04.1 LTS (GNU/Linux 5.10.102.1-microsoft-standard-WSL2 x86_64) on Windows 11 Pro.

Suggested run for Docker on WSL as shown above in second example passing in arguments as command line, rather than setting as environment variables.
