I run quite a few applications in Docker as part of my home network - there’s a small selection below, but at any one time there might be 10-15 more apps I’m playing around with:
plex - Streaming media server unifi - Ubiquiti Network Controller homebridge - Apple Homekit compatible smart home integration influxdb - Open source time series database grafana - Data visualization & Monitoring pihole - internet tracking and ad blocker vault - Hashicorp secret management Until recently a single PhotonOS VM with Docker was all I needed to run - everything shared the same host IP, stored it’s configuration locally or on an NFS mount and generally ran fine.
