Kobweb Site

This is a Kobweb project for generating the Kobweb site itself.

The goal of this site will be to highlight the features provided by the framework and the place to read documentation about it.

Build Docker image and push to GCR

• Make sure the Dockerfile is downloading the latest kobweb binary and do a export. For some reason export didn’t work inside docker container, so we do it here before building docker image
  kobweb export

• Build docker image
  docker build -t kobweb-site .

• Incase you first want to make sure the website runs locally
  docker run -p 8080:8080 -it kobweb-site

• Gcloud config to push the image to google cloud registry
  gcloud auth login
gcloud auth configure-docker

• Tag the image- kobweb-example-website-1 here is the GCP project id
  docker tag kobweb-site gcr.io/kobweb-example-website-1/kobweb-website

• Push the image
  docker push gcr.io/kobweb-example-website-1/kobweb-website
  
  

Deploy the docker container on Google Kubernetes Engine

Deploy for the first time

• Go to the project kobweb-example-website and open cloud shell OR set up gcloud locally. If you’re setting up locally on your computer, make sure
  gcloud auth list shows the correct active account

• Create GKE cluster in the specified zone and GCP project
  gcloud container clusters create kobweb-site-cluster --zone=us-west1-a --project=kobweb-example-website-1

• Fetch cluster endpoint and auth config
  gcloud container clusters get-credentials kobweb-site-cluster --zone us-west1-a --project=kobweb-example-website-1

• Create a new deployment
  kubectl apply -f gcp-deployment-config.yaml

• Verify deployment created
  kubectl get deployment

• Verfiy pod created
  kubectl get pods

• create a static IP address named kobweb-site-ip
  gcloud compute addresses create kobweb-site-ip --region us-west1 --project kobweb-example-website-1

• To find the static IP address you created, run the following command, Copy the 'address' to use as load-balancer-ip in the next command:
  gcloud compute addresses describe kobweb-site-ip --region us-west1 --project kobweb-example-website-1

• Copy pod name from previous command and create/expose the service on port 80, this will generate an external IP where we can access the website
  kubectl expose pod <POD_NAME> --port=80 --target-port 8080 --name=kobweb-site-service --type=LoadBalancer --load-balancer-ip=<STATIC_IP>

• Verfiy service created and copy the external IP. It can take a few seconds for this IP to show up
  kubectl get services

• Set horizontal autoscaling on the deployment, set the maximum number of replicas to 10 and the minimum to 2, with a CPU utilization target of 50% utilization
  kubectl autoscale deployment kobweb-site --max 10 --min 2 --cpu-percent 50

• Go to the web browser and open the external IP, it should show the website. It can take a few seconds to show up though because it's finishing up running kobweb run internally at this point. You can go to the GCP console to see the deployment logs.
