STEPS

Step 1: Create a Docker image and store the Dockerfile

gsutil cat gs://cloud-training/gsp318/marking/setup_marking.sh | bash

gcloud source repos clone valkyrie-app

cd valkyrie-app

cat > Dockerfile <<EOF

FROM golang:1.10

WORKDIR /go/src/app

COPY source .

RUN go install -v

ENTRYPOINT ["app","-single=true","-port=8080"]

EOF

docker build -t valkyrie-app:v0.0.1 .

cd ..

cd marking

./step1.sh

Step 2:Test the created Docker image

cd ..

cd valkyrie-app

docker run -p 8080:8080 valkyrie-app:v0.0.1 &

cd ..

cd marking

./step2.sh  

Step 3: Push the Docker image in the Container Repository

make sure you are out of the marking folder... to get out of the marking folder run: cd ..

cd valkyrie-app

docker tag valkyrie-app:v0.0.1 gcr.io/$GOOGLE_CLOUD_PROJECT/valkyrie-app:v0.0.1

docker push gcr.io/$GOOGLE_CLOUD_PROJECT/valkyrie-app:v0.0.1

sed -i s#IMAGE_HERE#gcr.io/$GOOGLE_CLOUD_PROJECT/valkyrie-app:v0.0.1#g k8s/deployment.yaml

Step 4: Create and expose a deployment in Kubernetes 

sed -i s#IMAGE_HERE#gcr.io/$GOOGLE_CLOUD_PROJECT/valkyrie-app:v0.0.1#g k8s/deployment.yaml

gcloud container clusters get-credentials valkyrie-dev --zone us-east1-d

kubectl create -f k8s/deployment.yaml

kubectl create -f k8s/service.yaml

git merge origin/kurt-dev

kubectl edit deployment valkyrie-dev

Step 5: Update the deployment with a new version of valkyrie-app

docker build -t gcr.io/$GOOGLE_CLOUD_PROJECT/valkyrie-app:v0.0.2 . 

docker push gcr.io/$GOOGLE_CLOUD_PROJECT/valkyrie-app:v0.0.2

kubectl edit deployment valkyrie-dev

docker ps

Step 6: Create a pipeline in Jenkins to deploy your app

docker kill [container_id]

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
