envoy-configs

Envoy configuration overlays applied on top of the shared base resources.

Deployment Scope

  • Cluster scope: global or site
  • Values keys: global.envoy_configs, site.envoy_configs
  • ArgoCD Application template: charts/argocd-understack/templates/application-envoy-configs.yaml

How ArgoCD Builds It

  • ArgoCD renders Kustomize path components/envoy-configs.
  • The deploy repo contributes values.yaml for this component.
  • The deploy repo overlay directory for this component is applied as a second source, so kustomization.yaml and any referenced manifests are part of the final Application.

How to Enable

Enable this component under the scope that matches your deployment model:

$CLUSTER_NAME/deploy.yaml
global:
  envoy_configs:
    enabled: true
site:
  envoy_configs:
    enabled: true

Deployment Repo Content

Use any secret delivery mechanism you prefer. The contract that matters is the final Kubernetes Secret or manifest shape described below.

Required or commonly required items:

  • values.yaml: Provide the configuration values consumed by the shared Envoy config base.
  • kustomization.yaml: Add any extra Gateway API, EnvoyPatchPolicy, or ConfigMap resources that your environment requires.

Optional additions:

  • No extra manifests are present in the current example overlay, but this directory is wired into ArgoCD and is the right place for site-specific Envoy resources.
