When a MUMBLE_CONFIG var is set, mumble will use it even if it is empty.
This caused problems e.g. when USERNAME="" caused all usernames to be
rejected.
One option to resolve this would be to keep unset-in-config variables
unset in the container. The other option is to supply mumble's default
values to the .env (which also makes the values more explicit).
This commit also removes a few config variables:
SSL would require more work to set up, as the server would need access
to the cert files
REGISTER is skipped for now as it would require an extra secret
LOG_DAYS is skipped because I'm not sure the logs are visible to the
user
Most of the options from mumble-server.ini have been added to .env
No documentation for these settings, since they're described elsewhere.
The exceptions which were not included are:
- *ssl* : adding support for custom certs needs more work
- database, *db*, *sqlite* : as above, for databases
- *ice* : unclear how ZeroC Ice works, decided to skip for now
- logfile, pidfile, *log* : would need to expose these files outside the
container
- port, host, uname : unneccessary in a container
- legacypasswordhash : unsecure, therefore requires custom compose file
- forceExternalAuth : undocumented
