Demo scenario

Create stagging-namespace

kubectl create ns stagging-namespace

Deploy app1 in stagging-namespace

export APP_NAME=mock-payment
export NAMESPACE=stagging-namespace
export ENV=stagging

helm upgrade --install -n ${NAMESPACE} ${APP_NAME}-${ENV} \
--values environments/${ENV}-values.yaml \
--values apps/${APP_NAME}/environments/${ENV}-values.yaml \
apps/${APP_NAME}/

Check app1 release is deployed in stagging-namespace

helm list --namespace ${NAMESPACE}

Check app1 resources are deployed in stagging-namespace

kubectl get deployment -n ${NAMESPACE}
kubectl get cm -n ${NAMESPACE}
kubectl get service -n ${NAMESPACE}

Curl app1 in stagging-namespace

export PORT=5000
export SERVICE_IP=$(kubectl get svc -n ${NAMESPACE} -l app=${APP_NAME} -ojsonpath='{.items[0].spec.clusterIP}')
curl -s http://${SERVICE_IP}:${PORT} -w "\n"

Update app1 image tag in stagging-namespace

vi apps/${APP_NAME}/environments/${ENV}-values.yaml

Upgrade app1 image in stagging-namespace

helm upgrade --install -n ${NAMESPACE} ${APP_NAME}-${ENV} \
--values environments/${ENV}-values.yaml \
--values apps/${APP_NAME}/environments/${ENV}-values.yaml \
apps/${APP_NAME}/

Curl ${APP_NAME} in stagging-namespace after upgrade

curl -s http://${SERVICE_IP}:${PORT} -w "\n"

Rollback app1 in to previous version stagging-namespace

helm rollback -n ${NAMESPACE} ${APP_NAME}-${ENV}

Check app1-stagging release values

helm get values -n ${NAMESPACE} ${APP_NAME}-${ENV}

Curl app1 in stagging-namespace after rollback

curl -s http://${SERVICE_IP}:${PORT} -w "\n"

Issue: in my GitRepo stored a verison but in my Cluster another version !!!

cat apps/${APP_NAME}/environments/${ENV}-values.yaml

Clean everything

helm uninstall -n ${NAMESPACE} ${APP_NAME}-${ENV}
kubectl delete ns ${NAMESPACE}
