The last time I talked about Docker, I mentioned several containers that I keep running 24/7. These are containers that I never spin down unless I'm updating them manually. Some readers had some fantastic suggestions for containers I hadn't tried yet. And for those who asked about containers that I don't actually keep running, I got to thinking about it, and there are definitely a few Docker containers that I only spin up when I need them. I was surprised to see that they're actually some of the most important containers I use.

I've been obsessed with Docker lately. I've been using it for a lot of things. I've also been getting back into Raspberry Pis over the last year or so. I was talking with a fellow writer here at HTG about different things to do with a Pi 4 in my budget home lab, and we got toDocker containers. I wondered if I could get them to work on this older SBC. It turned out I had some success with the project. It unlocked quite a few cool new ideas.

Pi-hole is one of my favorite services that solves an everyday problem without requiring expensive hardware. Install it on a Raspberry Pi, configure your devices to use it for DNS, and you can block unwanted domains while monitoring DNS activity across your network.

My homelab started with a single service, and before I knew it, I had a few dozen services running. In reality, I only use a handful of services every day—most of them sit idle or even offline.
