An Apache Airflow server, with Colors

Use this skill to initialize or operate an airflow project in the user's current directory. Compute and its R2 or S3 state use the directly pinned colors-compute library. It provisions one VPS running Airflow, a host Postgres archiving continuously to object storage, and a Caddy that terminates TLS and holds the only login. DAGs are pushed to it from a GitHub Actions workflow.

Requirements

uv runs the launcher. create and delete also need OpenTofu, Ansible and the gh CLI. Provider credentials use COLORS_PAR_* variables, except OCI, which uses the profile named in ~/.oci/config, and S3, which uses OpenTofu's ambient AWS credential chain.
