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.
