argocd-cmp-hk-deployment

Docker base image for the Hoverkraft ArgoCD custom CMP (Config Management Plugin) deployment integration.

Overview

  • Image purpose: Provides a containerized environment for ArgoCD to render and manage Hoverkraft deployments using Helm and Kustomize, with support for multi-source and single-source workflows.
  • Key scripts:
    • entrypoint.sh: call correct script depending of the argocd context
    • single-source.sh: Renders a Helm chart and applies Kustomize overlays, outputting the final Kubernetes manifests. Supports injection of deployment ID and ArgoCD environment variables.
    • multi-sources.sh: Generates a ConfigMap manifest for multi-source deployments, propagating the deployment ID.
  • Kustomize template: kustomize-template.tpl is used by the scripts to inject deployment-specific configuration.
