Collection of Packer templates used for various infrastructure layers.
Each Packer template JSON file is generated from a corresponding ERB-filtered YAML file. The primary reason for this is YAML's support for comments, references, and generally more flexible data structures. That being said, the structure of the single YAML document is analogous to the JSON structure expected by packer, and no further magic or indirection is expected or supported.
Editing a given JSON file directly is doing it wrong 🚫.
Instead, edit the YAML file and then run make, or alternatively use inline fd
docs for a slightly faster feedback loop, e.g.:
packer build - <(bin/yml2json < ci-minimal.yml)Most of the templates in here require some env vars. Take a look at
.example.env for an example.
