Learning how to use HELM charts
- To Create
dev and prod namespaces
$kubectl create namespace dev
$kubectl create namespace prod
- To install the Helm chart for the multiple environments
# for default environment
$helm install go-sample-app-release ./go-docker-sample-app \
--values ./go-docker-sample-app/values.yaml
# for dev environment
$helm install go-sample-app-release ./go-docker-sample-app \
--values ./go-docker-sample-app/values.yaml \
-f ./go-docker-sample-app/values-dev.yaml -n dev
# for prod environment
$helm install go-sample-app-release ./go-docker-sample-app \
--values ./go-docker-sample-app/values.yaml \
-f ./go-docker-sample-app/values-prod.yaml -n prod
- To list the installed Helm charts for all namespaces
$helm list --all-namespaces
- To view the created deployment, pods, and services for a namespace i.e. dev,prod
$kubectl get pods --namespace <namespace>
$kubectl get deployment --namespace <namespace>
$kubectl get service --namespace <namespace>
- To access the server via your local network
$minikube tunnel
# i.e. for the service in the 'dev' namespace
$kubectl port-forward service/go-sample-app :5045 --namespace dev
