Managing Directories - Solution

  • Example kustomization.yaml file:
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

# kubernetes resources to be managed by kustomize
resources:
  - db/db-config.yaml
  - db/db-depl.yaml
  - db/db-service.yaml
  - message-broker/rabbitmq-config.yaml
  - message-broker/rabbitmq-depl.yaml
  - message-broker/rabbitmq-service.yaml
  - nginx/nginx-depl.yaml
  - nginx/nginx-service.yaml
  • An example of creating a kustomization.yaml file per directory: 
    controlplane ~/code ➜  tree
.
└── k8s
  ├── db
  │   └── kustomization.yaml
  ├── kustomization.yaml
  ├── message-broker
  │   └── kustomization.yaml
  └── nginx
      └── kustomization.yaml
4 directories, 12 files
  • What the kustomization.yaml file would look like for k8s/db for example: ``` resources:
    • db-depl.yaml
    • db-service.yaml
    • db-config.yaml ```
  • In the root k8s directory, what the kustomization.yaml file would also look like: ``` apiVersion: kustomize.config.k8s.io/v1beta1 kind: Kustomization

kubernetes resources to be managed by kustomize

resources:

  • db/
  • message-broker/

  • nginx/ #Customizations that need to be made ```

  • How you would then apply the customisations: 
    controlplane ~/code ➜  kubectl apply -k /root/code/k8s/
--------------OR---------------
controlplane ~/code ➜  kustomize build /root/code/k8s/ | kubectl apply -f -
