Kipoi Webapp Kubernetes Setup

Requirements: You should have:

Download the repositories

Clone Kipoi Webapp Backend, Kipoi Webapp Frontend and Kipoi Webapp Router repositories. Ideally, they should be in the same

Copy the kubernetes folder inside kipoi-webapp-backend directory into the same parent folder.

Building and Publishing Backend Apps

Since there are two Kipoi environments, we have two different Flask apps to use those. Another app does the routing between them.

  • Navigate into kipoi-webapp-backend
  • Build the keras2 environment app: docker build -f Dockerfile -t YOUR_DOCKER_USERNAME/kipoi-backend-keras2:latest .
  • Push the keras2 environment app: docker push YOUR_DOCKER_USERNAME/kipoi-backend-keras2:latest
  • Build the keras1 environment app: docker build -f Dockerfile2 -t YOUR_DOCKER_USERNAME/kipoi-backend-keras1:latest .
  • Push the keras1 environment app: docker push YOUR_DOCKER_USERNAME/kipoi-backend-keras1:latest

Deploying Backend Pods on Kubernetes

  • Navigate into kubernetes folder.
  • Change goktugerce in kipoi-backend-keras1-deployment.yaml and kipoi-backend-keras2-deployment.yaml with YOUR_DOCKER_USERNAME.
  • Deploy the Flask apps on pods:
    • kubectl apply -f kipoi-backend-keras2-deployment.yaml --record
    • kubectl apply -f kipoi-backend-keras1-deployment.yaml --record
  • Check container statuses with kubectl get pods and wait until both containers are running.
  • Deploy the load balancer services:
    • kubectl apply -f service-kipoi-backend-keras2-lb.yaml
    • kubectl apply -f service-kipoi-backend-keras1-lb.yaml
  • Find the IPs of services with minikube service list

Building and Publishing Router App

  • Navigate into kipoi-webapp-router
  • Build the Docker image:
    • docker build -f Dockerfile -t YOUR_DOCKER_USERNAME/kipoi-router:latest .
  • Publish the Docker image:
    • docker push YOUR_DOCKER_USERNAME/kipoi-router:latest
  • Edit kipoi-backend-router.yaml accordingly with IPs of environment services.
  • Replace goktugerce with YOUR_DOCKER_USERNAME in the same file.
  • Deploy it in a pod:
    • kubectl apply -f kipoi-backend-router.yaml --record
  • Deploy the load balancer service:
    • kubectl apply -f service-kipoi-router-lb.yaml
  • Find the IP of service with minikube service list

Building and Publishing Frontend App

  • Navigate into demo-webapp-frontend folder.
  • Edit src/helpers/URL.js file with IP address of the router service.
  • Run yarn install to install necessary packages.
  • Run yarn build to package the frontend app.
  • Build the Docker image:
    • docker build -f Dockerfile -t YOUR_DOCKER_USERNAME/kipoi-frontend:latest .
  • Publish the Docker image:
    • docker push YOUR_DOCKER_USERNAME/kipoi-frontend
  • Deploy the frontend app in a pod:
    • kubectl apply -f kipoi-frontend-deployment.yaml --record
  • Deploy the load balancer service
    • kubectl apply -f service-kipoi-frontend-lb.yaml
  • Find the IP of frontend app with minikube service list
  • Navigate to the IP and start using the app.
