These manifests define extra ingress routes, most notably routes that are proxied external to the cluster. To facilitate easier declaration, the manifests are generated by a simple templating script with YAML configuration through Jinja templating.

We decided on the templating solution over Helm because FluxCD, our GitOps tool, requires a Helm repository to apply a Helm chart. We don't have a Helm repository and it seems overkill to create even a simple Helm repository just for a single chart. Additionally, creating a Helm repository creates another point of failure and adds complexity in the GitOps pipeline.

Templating script

By default, templater/main.py sources the config from templater/values.yaml and emits the templated manifests into build/.

Run templater/main.py -h for a full list of arguments.
