I have been using Seafile for years to host and synchronise files on my own server. It’s fast and reliable, especially when dealing with a large number and size of files. But making reliable backups of all its files isn’t so trivial. This is because the files are stored in a layout similar to bare Git repositories, and Seafile’s headless tool, seafile-cli, is… suboptimal. So I created what started out as a wrapper for it and ended up as a full-blown tool for automatically synchronising your libraries to a backup location: Seafile Mirror.
So you have a number of Docker containers running web services which you would like to expose to the outside? Well, you probably will at least have considered a reverse proxy already. Doing this manually for one, two or even five containers may be feasible, but everything above that will be a PITA for sure. At the FSFE we ran into the same issue with our own distributed container infrastructure at and crafted a neat solution that I would like to present to you in the next few minutes.
