Automatically renew Mumble TLS certificate
Problem to solve
Currently Mumble is using a Let's Encrypt certificate, that is manually copied from the Traefik certificate store. Because of the short lifetime of the certificates, it will expire after only 3 month. If the certificate is not changed in this period, users connecting to Mumble will receive a warning message about the expired certificate. Therefore the error prone manual certificate exchange should be automated.
Proposal
There are some scripts, that can watch Traefiks certificate store for changes and automatically extract changed certs. We can use this feature and combine it with a custom script, that exchanges the cert of Mumble and restarts the Mumble server.
