GitOps Baseline with Flux v2

GitOps on EKS — Flux Bootstrapped, GitHub Connected, Notifications Wired

Flux is powerful and surprisingly quick to set up badly. This baseline gives you a Terraform-managed Flux install with GitHub integration, image update automation, and Slack deployment notifications — the complete picture, not just the getting-started tutorial.

What is Included

• Terraform module bootstrapping Flux v2 onto an EKS cluster via the Flux provider
• GitHub repository connection with deploy key management
• Image update automation: Flux polls ECR for new image tags and commits updated manifests automatically
• Slack notification provider with alerts for successful reconciliations and failures
• Multi-environment structure: separate clusters/staging/ and clusters/production/ directories in the GitOps repo

Developer Experience

Run Terraform, Flux bootstraps itself, connects to your repo, and starts reconciling. Push a new image tag to ECR and watch Flux update the manifest and deploy — with a Slack message confirming it.

What You Get

• terraform/ — Flux bootstrap module with GitHub and EKS inputs
• flux-repo/ — example GitOps repository structure ready to push to GitHub
• image-automation/ — ImageRepository, ImagePolicy, and ImageUpdateAutomation manifests
• notifications/ — Slack Provider and Alert manifests
• README.md covering the bootstrap sequence, repo structure, and day-2 operations

Requirements

• EKS cluster with IRSA and an accessible GitHub repository
• Terraform >= 1.3, Flux CLI for verification
• ECR registry for image update automation (adaptable to DockerHub or GHCR)
• Slack webhook URL for deployment notifications
