If you’ve used Docker Desktop on Windows for a while, you’ve probably hit the annoying problem when your free disk space slowly disappears. Even when you delete containers or images, the space never comes back. Docker just keeps growing until your drive is full.

Software principles form the foundation of systems that are clean, scalable, and easy to maintain. They serve as essential guidelines during design and development, helping create code that’s well-structured, readable, and adaptable. By following these principles, developers can reduce bugs and elevate the overall quality of their software.

In the previous article we configured Traefik to use magic domain name like traefik.me. In this article we configure it with your domain and Let’s Encrypt certificated authority.

Sometimes during development we want to use domain names instead of IP addresses and ports, proper domain certificates instead of self-signed to make local environment similar to production, etc.. This problem can be solved with any reverse proxy and magic domain names like traefik.me, nip.io, sslip.io, etc..

Recently, I’ve developed Android app that during the development requires access to the backend service that is run in the docker behind reverse-proxy with custom myservice.traefik.me domain name.
For sure, from emulator you can get access to your local service when connect to it by IP address with specified port. But this approach leads to some issues and ugly workarounds in a code.
There are several solutions to this problem like edit hosts file, run own DNS server etc. But the simplest one is just simply editing hosts file on emulator.
