React App on Google Kubernetes Engine (GKE)

A reference project to deploy a React app onto Google Kubernetes Engine (GKE)

Referencing this GCP documentation

Pre-requisites

• Google Cloud SDK already installed locally
• Install the kubectl CLI tool:

gcloud components install kubectl # installs the kubectl CLI tool

Build/Push the Docker image

• Create a GCP project. Then, run the following commands:

docker build -t gcr.io/<your_project_id>/gcp-k8-react-app:v1 . # builds the Docker image
docker run --rm -p 8080:8080 gcr.io/<your_project_id>/gcp-k8-react-app:v1 # runs the image in a container at http://localhost:8080/
gcloud auth configure-docker # configure Docker CLI tool to authenticate with Container Registry
docker push gcr.io/<your_project_id>/gcp-k8-react-app:v1 # pushes image to Container Registry!

Deploy app to GKE

• Create a GKE cluster:

gcloud config set project <your_project_id> # set your gcloud project ID
gcloud config set compute/zone europe-west2-a # set your gcloud compute zone
gcloud container clusters create gcp-k8-react-cluster # create a GKE cluster
gcloud container clusters get-credentials gcp-k8-react-cluster --zone europe-west2-a --project <your_project_id> # set your local kubectl command to run against the GKE environment

• Create a deployment:

kubectl create deployment gcp-k8-react-cluster --image=gcr.io/<your_project_id>/gcp-k8-react-app:v1 # creates a deployment
kubectl expose deployment gcp-k8-react-cluster --name=gcp-k8-react-app-service --type=LoadBalancer --port 80 --target-port 8080 # exposes the deployment via a load balancer
kubectl get service # lists services. Find app URL in EXTERNAL-IP

• Clean-up:

kubectl delete service gcp-k8-react-app-service # deletes service
gcloud container clusters delete gcp-k8-react-cluster # deletes cluster
gcloud container images delete gcr.io/<your_project_id>/gcp-k8-react-app:v1  --force-delete-tags --quiet # deletes image
