Demonstration of using Kustomize to deploy to multiple namespaces/environments with different Images and Configurations. Which can be combined with CI/CD Tools triggered by Git Tags for automated deployments.
Using the upstream Kustomize - requiring to 'build | apply' - over version included with 'kubectl' due to it lagging with current version causing issues and not fully compatible with current Kustomize documentation.
Install Kustomize:
https://kubectl.docs.kubernetes.io/installation/kustomize/
Create namespace(s):
kubectl create namespace [staging|uat|live]Apply manifests:
kustomize build [staging|uat|live] | kubectl apply -f - Clean up:
kustomize build [staging|uat|live] | kubectl delete -f -
