ALC 4 Cloud Challenge Phase II using GCP Virtual Machine

Prerequisites:

  1. Cloud SDK installed and setup on your local machine
  2. Windows Professional version
  3. Administrative rights on your local machine
  4. Google Cloud Account
  5. Internet
  1. Create the virtual machine,
  2. Install node and docker,
  3. Create your application and docker image,
  4. Push the created image to google container registry ,
  5. Create Kubernetes cluster,
  6. Deploy the gcr container to the cluster, and
  7. Expose the deployment using a LoadBalancer.
gcloud beta compute --project=spikey-bigtable-new instances create challenge-vm --zone=us-central1-a --machine-type=g1-small --tags=http-server,https-server --image=ubuntu-1604-xenial-v20191010 --image-project=ubuntu-os-cloud --boot-disk-size=10GB --boot-disk-type=pd-standard --boot-disk-device-name=ubuntu-vm
  • “ — machine-type” of “g1-small” to reduce cost
  • “ — image” of “ubuntu-1604-xenial” for the simple reason that I am a lover of Ubuntu
  1. Stop the instance
  2. Click the Edit button at the top of the page.
  3. Under Custom metadata, click Add item.
  4. Add your startup script using one of the following keys:
  • startup-script: Supply the startup script contents directly with this key.
  • startup-script-url: Supply a Cloud Storage URL to the start script file with this key.

  1. Install yarn,
sudo npm install -g yarn
yarn add global create-react-app
# windows users
yarn create-react-app challenge-app
cd challenge-app
yarn start
# for Ubuntu users
create-react-app challenge-app
cd challenge-app

  1. Set up the instance to allow pushing of docker images to google container registry:
gcloud compute instances stop challenge-vm --zone=us-central1-a
gcloud compute instances set-service-account challenge-vm --scopes=storage-rw --zone=us-central1-a
gcloud compute instances start challenge-vm
gcloud auth configure-docker
sudo chown $USER:$USER ~/.docker/config.json

tar xvf google-cloud-sdk-267.0.0-linux-x86_64.tar.gz
cd google-cloud-sdk && ./install.sh
sudo rm -rf /usr/lib/google-cloud-sdk
gcloud components install docker-credential-gcr
gcloud auth print-access-token | sudo docker login -u oauth2accesstoken --password-stdin https://gcr.io
gcloud compute firewall-rules create docker-rule-out --allow=tcp --direction=EGRESS --destination-ranges="0.0.0.0/0"
docker login --username <your_username>
sudo docker tag udoyen/challenge-image gcr.io/spikey-bigtable-new/challengeapp:ubuntu-version
sudo docker push gcr.io/spikey-bigtable-new/challengeapp:ubuntu-version
gcloud beta container --project "spikey-bigtable-new" clusters create "challenge-cluster" --zone "us-central1-a"  --machine-type "g1-small" --num-nodes "3"
gcloud components install kubectl

kubectl create deployment challenge-deploy --image=gcr.io/spikey-bigtable-new/challengeapp:ubuntu-version
kubectl expose deployment challenge-deploy --type=LoadBalancer --port 80 --target-port 80
