Split DNS forwarding from Unifi gateway
Posted on December 28, 2021 Leave a Comment
When using Traefik, or any other reverse proxy, in front of docker containers you need a proper domain to get an SSL certificate from LetsEncrypt. You also need a proper public DNS for the domain to allow LetsEncrypt to verify ownership via DNS or web requests. If you want to use this for internal systems […]
Traefik reverse proxy with docker swarm
Posted on September 28, 2020 2 Comments
A reverse proxy is used to distribute the traffic over a scalable application running in several containers. This is needed since you can’t publish the port for all the containers. Traefik is a docker aware reverse proxy that can route and distribute all the incoming traffic to the correct containers. We are going to solve […]
MySQL on Docker Swarm revisited

If you ever ended up with a broken Unifi Controller or Cloud Key you know the hassle it is to re-adopt and re-provision all your network gear to get back to square one. You should really keep track of the automatic backups from […]

For several applications around the house, I need a MySQL backend. The biggest database I run is about 60Mb of data for my Kodi media players. By using centralized storage like this I only need to update one of them when I add new media. Also convenient if I watch a movie in the living […]
Raspberry Pi Docker Swarm

For small home server applications like Hassio, Plex and headless BitTorrent boxes Raspberry Pi has been a great solution for years. I came to a point where I was running several ones with different software on it depending on it’s intended use. This, however, isn’t ideal for a number of reasons. Even though Raspberry Pis […]
