Summary: This guide covers managing Kubernetes configuration directories and using Kustomize for efficient deployments.

Key Notes

  • In this demo, we review how to efficiently manage your Kubernetes configuration directories. The example uses a structured “k8s” directory containing three subdirectories, each dedicated to a distinct application component:
  • api/
  • cache/
  • db/
  • Within each subdirectory, YAML files define deployments, services, config maps, and other Kubernetes resources. This guide describes the setup, key commands, and benefits of using Kustomize to streamline deployments.
  • MongoDB Deployment Example
  • MONGO_INITDB_ROOT_USERNAME
  • MONGO_INITDB_ROOT_PASSWORD
  • Service and ConfigMap Example
  • redis-cluster-ip-service
  • Additionally, before introducing Kustomize, the demo deploys resources using the standard method. Here is a sample ConfigMap for Redis credentials:
  • “redis”
  • “password123”
  • Kubernetes Documentation
  • Deploying the Configurations Without Kustomize
  • kubectl apply
  • k8s/
  • This command deploys all configurations within the “k8s” folder. Alternatively, you can apply each subdirectory individually:
  • k8s/api
  • k8s/cache
  • k8s/db
  • To remove these resources from your cluster, run:
  • Introducing Kustomize
  • kustomization.yaml
