FastAPI and Uvicorn Logging

When running FastAPI app, all the logs in console are from Uvicorn and they do not have timestamp and other useful information. As Uvicorn applies python logging module, we can override Uvicorn logging formatter by applying a new logging configuration.

Meanwhile, it's able to unify the your endpoints logging with the Uvicorn logging by configuring all of them in the config file log_conf.yaml.

Before overriding:

uvicorn main:app --reload

WireGuard Site-to-Site

Accessing a subnet that is behind a WireGuard client using a site-to-site setup

Problem Summary

We want to access a local subnet remotely, but it is behind a NAT firewall and we can't setup port forwarding. Outgoing connections work, but all incoming connections get DROPPED by the ISP's routing policy.

Solution Summary

atlasloewenherz

# All other flavors inherit the `common' config snippet
common: &common
    issue: '"docker-registry server"'
    # Default log level is info
    loglevel: _env:LOGLEVEL:info
    # Enable debugging (additional informations in the output of the _ping endpoint)
    debug: _env:DEBUG:true
    # By default, the registry acts standalone (eg: doesn't query the index)
    standalone: _env:STANDALONE:true
