Replace ArgoCD with Flux, SealedSecrets with SOPS+age, add minikube CI workflow

[Copilot]

Migrate GitOps stack from ArgoCD to Flux v2 and from SealedSecrets to SOPS with age encryption. Strip to minimal working state (hello-world only) with a CI workflow that proves deployment end-to-end on minikube.

GitOps: ArgoCD → Flux

• Removed ArgoCD ApplicationSet, ConfigMap plugin, and all related config
• New Flux structure: clusters/homelab/ contains Kustomization CRDs pointing to apps/ and infrastructure/ directories
• SOPS decryption configured directly in Flux Kustomization via spec.decryption

Secrets: SealedSecrets → SOPS + age

• Removed Sealed Secrets controller and all SealedSecret manifests
• .sops.yaml updated with encrypted_regex: ^(data|stringData)$ for *.enc.yaml files
• Age key management documented (generation, import, backup, rotation)

App cleanup

• Removed ~20 apps (authentik, traefik, longhorn, velero, monitoring stack, etc.) and the generic-service/namespace Helm charts
• Single hello-world app with Deployment (exec probes, resource limits), Service, Namespace, SOPS-encrypted Secret

CI: minikube deployment test

# .github/workflows/test-flux-deployment.yaml
- Start minikube, install Flux + SOPS/age
- Generate ephemeral age key, replace encrypted secrets with plain equivalents
- kubectl apply -k kubernetes/apps/
- Verify rollout, port-forward, assert HTTP 200

Updated workflows & scripts

• verify-kustomize.yaml builds new paths (kubernetes/apps, kubernetes/infrastructure/*)
• validate_manifests.py excludes clusters/ dir (Flux-managed, not referenced in kustomization)
• new-Cluster.ps1 rewritten for flux bootstrap github + SOPS age secret creation
• Removed ArgoCD revision validator and SealedSecret helper scripts

README

Complete rewrite covering: repo structure, Flux reconciliation flow, SOPS secret lifecycle (create/edit/view), age key management (import/backup/rotate), adding new apps (plain manifests and HelmRelease), CI/CD matrix.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Create a test branch that replaces argocd with the latest version of flux following the best practices. I like my current helm + kustomize setup, but if there are better ways in flux , inplement it.

I like to move away from sealedsecret and use SOPS everywhere.

You may remove most apps and only show a working version with the bare minimum, like the hello world app.

Make a new workflow that launches a small throw away cluster ( I think it's called minikube?) to test if it deploys correctly.
Make the workflow test if the pods are up and the routes reachable.

Follow best practices 2026.

Update the readme, Make clear instructions how to add new apps and manage SOPs, how to import an age file for sops, how to backup the age key used in the cluster, etc.

Don't quit until the cluster deploys and the hello world is reachable for you, and everything I asked for is 100% working, secure, following best practices.
