I also started with a simple shell script. Upload sources, build on the target system (golang) and restart the systemd service(es). Then, I needed to make another machine like this, so enter Ansible. This worked well for a long time, and was relatively content with it. Along the way, I leaned about nix (and enough of it) to adopt a simple flake to pull out my tools (like golang, ansible, terraform) through. For a long time, I used it like this (e.g. still ansible, but I started building locally) Finally, I learned enough nix to adopt NixOS. Now, I've converted my project to a nix package and a NixOS module, which allows me to totally describe the state of the machine I want. With this, remote builds and colmena (mostly for pushing secrets), I deploy a complete system, including my own software.
