GKE Terraform

This project aims to deploy a Kubernetes cluster on Google Cloud Platform (GCP) using Terraform. The infrastructure will include a load balancer for ingress, instances, and instance groups. Additionally, it will showcase the integration of a basic Next.js application, containerized with a small program rendering the Cohere logo on page load.

Requirements

TOOL	VERSION
Terraform	v1.7.4
Python	3.12.2
GCloud	Google Cloud SDK 466.0.0
Node	v20.11.1

Build & Push

$ chmod +x ci/scripts/build-and-push-app.sh
$ python3 ci/scripts/build-and-push-all.py  --config ci/configs/pipeline-config.json --gitsha [GIT SHA] --registry gcr.io/[PROJECT_ID]

Run App

The App is a simple nextjs app for k8s cluster access testing purposes.

• npm install

Build

This command builds the app for production

$ npm run build

Start

This command launches app with build configuration and files

$ npm run dev # runs in development mode and does not require pre-build
$ npm run start

Infrastructure as Code

IaC is setup with Terraform. resouce modules are build in the terraform/modules directory and consumed when building each sub environment in environment/[env]

Plan

$ python3 ci/scripts/execute-terraform.py --command plan --config ci/configs/pipeline-config.json --env dev

Apply

$ python3 ci/scripts/execute-terraform.py --command apply --config ci/configs/pipeline-config.json --env dev
