Cluster Configuration Manifests clusters/clusterone

This directory contains the primary manifests for a cluster named clusterone in Edka. Any YAML manifest added here will be applied to the cluster.

Note: Kustomization is used to manage resource dependencies and installation order.

• cluster-secrets-store.yaml: Integrates External Secrets to sync secrets from providers like Doppler, avoiding hardcoded secrets in Git. Its resources are located in clusters/resources/clusterone/secrets.

• namespaces.yaml: Defines Kubernetes namespaces for organizing resources and add-ons (e.g., production, preview, etc.).

• postgres.yaml: Configures a PostgreSQL Cluster using the Cloud Native PostgreSQL operator with HA, backups, and PITR from AWS S3. Its resources are located in clusters/resources/clusterone/postgres.

• shared.yaml: Sets up shared configurations that usually are the same for all your clusters. It references shared manifests in clusters/shared.

Resources clusters/resources

This directory holds the detailed resource configurations, organized by cluster name. These are referenced by the manifests within each cluster's specific directory (e.g., clusters/clusterone).

Shared Configurations clusters/shared

This directory contains shared configurations that can be used across multiple clusters. For example, the helmrepository.yaml file defines a Helm repository to allow pulling private Helm charts from a private repository.
