Run Coder in a self-hosted homelab

The author outgrew their little homelab consisting of ODROID-HC2 devices for serving files and experimenting with ARM assembly. They decided to expand their homelab to handle development projects as well, using a used Lenovo m92P Tiny with 16 GB RAM and upgraded its spinning disk with a 1 TB SSD. The author installed Debian and crammed Marvin into the homelab closet. They then installed Docker Engine for Debian and Coder on Marvin, which is a solution that allows self-hosting of projects and working on them wherever and however one wants. The author set up their first workspace using a Docker template and confirmed that Docker was running their workspace. With Coder's public access URL, they can now work on their homelab-hosted projects from anywhere.
