Introduction to Hercules CI, NixOps and a step by step demonstration of setting up a continuous delivery pipeline with these tools. Hercules CI is a continuous integration service that coordinates build agents on your own infrastructure. It is built around Nix for the best developer user experience. NixOps is the Nix ecosystem's primary deployment tool, supporting multiple clouds through its Nix-based input format. By integrating the two, we achieve a continuous delivery pipeline that is configured entirely with Nix.
