Backing up docker volumes

In today’s I-can’t-believe-I’m-doing-this-in-2024

I needed to re-build my webserver because it kept hard-freezing every week (another post for another day). Since I use a docker setup for this, my setup is pretty turnkey - I just needed to copy over my docker volumes from the old host to the new host.

That turned out to be a lot more annoying than what I wanted. See, this functionality hasn’t existed for a long time. You had to use some DIY StackOverflow scripts. Apparently, this functionality is now built into Docker Desktop, but A. I’m ssh’d into a server and B. Docker Desktop is the trojan horse where they extort people for licenses. In either case, I just have access to the docker daemon.

Previously, we’ve covered terminating SSL connections and running cron jobs. Now it’s time to actually set up a wordpress installation. The two main ingredients are a web server, and a php server. All requests go through the web server (nginx, again in this case). If the filepath ends in a .php extension, then the request gets forwarded to the php-fpm (basically php with a FastCGI implementation) to do the server-side processing.

Today, I’m going to talk about running background jobs with docker. On a non-docker system, you can set up a server to do many things at once - for example run nginx AND update your SSL certs periodically. However, with Docker, you have to choose. You either need to run each process as a separate docker container, or you need to use some sort of supervisor process (supervisord, s6, systemd, etc) which will in-turn kick off the other processes you’re interested in.

Those segfaults I mentioned? Yeah, they proved unsolvable. Nginx Unit seems to be having a rough time and un-extracting Nginx Unit from the install script was more difficult than expected too.

Instead, I spent more time than that setting up my own cluster of docker containers. The benefit is that I can now run a whole copy locally, test changes, and then push to production. It also allows me to track what changes to all the various .conf files I’ve been making. Today, I’ll talk about setting up a SSL-terminating reverse-proxy, and how to host it with docker-compose.
