Kubernetes manifests to deploy a flask application with nginx reverse proxy, redis cache and mysql database on Google Kubernetes Engine ensuring high availability and scalablility

Deploying a Fullstack Application with 3-Tier Architecture on Google Kubernetes Engine (GKE)

Steps

1. Create a new project on Google Cloud Platform (GCP)

2. Enable the Kubernetes Engine API

3. Install the Google Cloud SDK on your local machine

4. Clone the repository and navigate to the backend directory

5. Login to Google Cloud SDK and set the project

   gcloud auth login
   gcloud config set project YOUR_PROJECT_ID
   

6. Enable/Install the required services

   gcloud services enable artifactregistry.googleapis.com
   gcloud auth configure-docker
   gcloud components install gke-gcloud-auth-plugin
   

7. Build the Docker image, replace HOST-NAME, PROJECT-ID, REPOSITORY, and IMAGE with your own values for

   docker build -t HOST-NAME/PROJECT-ID/REPOSITORY/IMAGE:latest .
   

8. Push the Docker image to Google Artifact Registry

   docker push HOST-NAME/PROJECT-ID/REPOSITORY/IMAGE
   

9. Create a Kubernetes cluster

10. Configure kubectl to use the new cluster

    gcloud container clusters get-credentials CLUSTER_NAME --zone ZONE --project PROJECT_ID
    

11. Enable Gateway API for the cluster

    gcloud container clusters update CLUSTER_NAME --location=ZONE --gateway-api=standard
    

12. Navigate to the root directory of project, replace <DOCKER_IMAGE>, <MYSQL_PASSWORD>, <MYSQL_DATABASE_NAME> with your own values, and deploy the configuration

    kubectl apply -f deploy.yml
