Kubernetes Cluster & Terraform

Goal:

Lets see if I can deploy a web app to my EKS cluster & Terraform. After EKS cluster is deployed w/Terraform I’ll provision the cluster & run Node.js & use MongoDB as the backend DB.

Basically it goes like this:

• Web Browser – – – EKS Cluster – – – Public Endpoint
• Namespace – – – Node.js – – – Docker Image Repository – – – MongoDB

Lessons Learned:

• Deploy EKS Cluster w/Terraform:
• Complete Terraform Configuration:
• Deploy Web App w/Terraform:
• Scale Kubernetes Web App:

Deploy EKS Cluster w/Terraform:

• Cloud User – – – Security Credz – – – Access Keys

• Add key details in CLI

Couple Commands to Leverage for Sanity Check:

• LS files
• Unzip
• LS
• CD
• LS
  • Now can see all TF files

Terraform – init, fmt, apply:

Complete Terraform Configuration:

Double Check its Running:

Couple Commands:

Vim modules/pac-man/pac-man-deployment.tf:

Vim pac-man.tf:

Terraform – Fmt, Init, & Apply:

Deploy Web App w/Terraform:

Scale Kubernetes Web App:

Change Deployment Files

• MongoDB = 2
• Pacman Pods = 3
