I use Docker to administer about 20 different services on a personal server hosted in Germany by Hetzner. I run my own instance of Nextcloud, which offers functionality similar to Dropbox but is open source and completely customizable. I administer the server and keep everything running smoothly through the use of monitoring tools such as Netdata and orchestration tools such as Portainer. I also have written my own directory which connects with UpTimeRobot to track service uptime.
