STEPS

Go to kraken-jumphost ssh

gcloud config set compute/zone us-east1-b

git clone https://source.developers.google.com/p/$DEVSHELL_PROJECT_ID/r/sample-app

gcloud container clusters get-credentials jenkins-cd

kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=$(gcloud config get-value account)

helm repo add stable https://kubernetes-charts.storage.googleapis.com/  → this might not work… use the next line of code instead…

helm repo add stable https://charts.helm.sh/stable

helm repo update

helm install cd stable/jenkins

Go to cloudshell

export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/component=jenkins-master" -l "app.kubernetes.io/instance=cd" -o jsonpath="{.items[0].metadata.name}") kubectl port-forward $POD_NAME 8080:8080 >> /dev/null & printf $(kubectl get secret cd-jenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode);echo

open web portal on 8080

login

go to manage credentials

add credential

select "google service account from metadata"

select your project id

Go to ssh of kraken-jumphost

cd sample-app

open editor

open main.go and replace the version with the version mentioned

open html.go and replace the color with the color mentioned

go back to cloud shell

kubectl create ns production

kubectl apply -f k8s/production -n production

kubectl apply -f k8s/canary -n production

kubectl apply -f k8s/services -n production

go back to jenkins

new item

multibranch pipeline

add source --> git

go back to command shell and implement the two commands:

kubectl get svc

kubectl get service gceme-frontend -n production

Go back to Jenkins

put the git link

##Branch Sources: Git

            - Project Repository: https://source.developers.google.com/p/[PROJECT_ID]/r/sample-app

click Periodically if not...... 1 min

git init

git config credential.helper gcloud.sh

git remote add origin https://source.developers.google.com/p/$DEVSHELL_PROJECT_ID/r/sample-app

git config --global user.email "<user email>"

git config --global user.name "<user name>"

git add .

git commit -m "initial commit"

git push origin master

#save

git checkout -b new-feature

git add Jenkinsfile html.go main.go

git commit -m "Version 2.0.0"

git push origin new-feature

curl http://localhost:8001/api/v1/namespaces/new-feature/services/gceme-frontend:80/proxy/version kubectl get service gceme-frontend -n production git checkout -b canary git push origin canary export FRONTEND_SERVICE_IP=$(kubectl get -o \ jsonpath="{.status.loadBalancer.ingress[0].ip}" --namespace=production services gceme-frontend) git checkout master git push origin master

export FRONTEND_SERVICE_IP=$(kubectl get -o \ jsonpath="{.status.loadBalancer.ingress[0].ip}" --namespace=production services gceme-frontend) while true; do curl http://$FRONTEND_SERVICE_IP/version; sleep 1; done

kubectl get service gceme-frontend -n production

git merge canary git push origin master export FRONTEND_SERVICE_IP=$(kubectl get -o \ jsonpath="{.status.loadBalancer.ingress[0].ip}" --namespace=production services gceme-frontend)
