Deploy to multiple environments

Docker images

Create two docker images first, one for nas, another for prod.

docker build -t jojozhuang/text-compare-angular-nas -f Dockerfile-nas .
docker build -t jojozhuang/text-compare-angular-prod -f Dockerfile-prod .

List all images and make sure jojozhuang/text-compare-angular-nas and jojozhuang/text-compare-angular-prod are there.

docker images
REPOSITORY                             TAG       IMAGE ID       CREATED         SIZE
jojozhuang/text-compare-angular-prod   latest    4a53306114f5   4 seconds ago   30.8MB
jojozhuang/text-compare-angular-nas    latest    ee561a5e50b3   5 hours ago     30.8MB
jojozhuang/text-compare-angular        latest    ee561a5e50b3   5 hours ago     30.8MB

Push to docker hub.

docker push jojozhuang/text-compare-angular-nas
docker push jojozhuang/text-compare-angular-prod

If you don't push them to hub.docker.com, you might get ErrImagePull error.

kubectl get all -n prod
NAME                                READY   STATUS              RESTARTS   AGE
pod/compare-helm-57f779585d-6c665   0/1     ErrImageNeverPull   0          5s
pod/compare-helm-6c5668997f-kzk9n   0/1     ErrImagePull        0          105s

Environment specified value files

Copy values.yaml and create for nas and prod env.

kubectl create namespace nas
kubectl create namespace prod

Check new namespaces nas and prod are created.

kubectl get namespaces
NAME                   STATUS   AGE
bit-developer          Active   70m
default                Active   6h24m
kube-node-lease        Active   6h24m
kube-public            Active   6h24m
kube-system            Active   6h24m
kubernetes-dashboard   Active   6h23m
nas                    Active   14s
prod                   Active   13s

Install for nas and prod namespaces.

helm install compare-helm-nas deployment --values deployment/values.yaml -f deployment/values-nas.yaml -n nas
helm install compare-helm-prod deployment --values deployment/values.yaml -f deployment/values-prod.yaml -n prod

List all namespaces.

helm ls --all-namespaces
NAME             	NAMESPACE	REVISION	UPDATED                             	STATUS  	CHART           	APP VERSION
compare-helm     	default  	6       	2024-01-07 21:49:34.420836 -0800 PST	deployed	deployment-0.1.0	1.16.0
compare-helm-nas 	nas      	1       	2024-01-07 22:10:09.473106 -0800 PST	deployed	deployment-0.1.0	1.16.0
compare-helm-prod	prod     	1       	2024-01-07 22:10:20.00086 -0800 PST 	deployed	deployment-0.1.0	1.16.0

kubectl get all -n prod
kubectl describe pod compare-helm-77ddc9bc6b-xf96c -n prod

helm upgrade compare-helm-nas deployment --values deployment/values.yaml -f deployment/values-nas.yaml -n nas
helm upgrade compare-helm-prod deployment --values deployment/values.yaml -f deployment/values-prod.yaml -n prod

Start nas service and prod service seperately and access http://localhost:8888/. You will see the env name on the home page is shown correctly, from nas to production.
