Done
As the home server I use the Raspberry Pi 3b with heat sink and Ubuntu MATE.
Docker runs above the operating system and all other web services are in docker containers.
The first container is traefik. This is a proxy-service which allows me to address the individual containers via simple subdomains. It also supports Letsencrypt, which secures SSL usage.
The second most important container is Pi Hole. It describes the whole network of advertising and malware by matching every DNS request with the domains-blacklists. If there is a request to a blacklisted domain, the Pi Hole responses with an empty answer. To do this, Pi Hole is set in all router as the default DNS server.
Once the network's usability and security are in sight, the container can be installed with the applications, which can then be used by the users / my family.
At the moment, the services Nextcloud and GitLab are running with an external hard disk for more memory.
