Opening P2Panda ports with Traefik

Supporting P2Panda apps like lores-node requires a change to the default Co-Op Cloud Traefik config.

You might recall that when we setup Accessing our Pi from the internet, we learned about how TCP and UDP both use ports, and we setup port forwarding on our router for the ports we need for web traffic, and also for UDP ports 2022 and 2023 for P2Panda.

Now that we’re installing lores-node, we need traffic to those ports to be accepted and routed by Traefik to the correct app. Even if you aren’t doing port forwarding on your router (perhaps because you’re just using your node on a local network), you still need to do this step.

Edit Traefik config

It’s time to edit our Traefik config with abra again:

abra app config traefik.YOUR_SERVER_DOMAIN

You should find a line in that file that says P2PANDA_ENABLED=1, but it’ll be commented out (there’s a hash character # in front of it). Remove the hash to enable this line.

Re-deploy Traefik

Re-deploy Traefik with:

abra app deploy -f traefik.YOUR_SERVER_DOMAIN

The -f stands for force, and you’ll need this if it’s already deployed and you’ve made config changes.

Push our changes to git

If we’re happy that our changes to the Traefik config, we can push them to git.
