DEPLOYMENT CHECKLIST

Pre-Deployment Setup

• Docker installed locally
• Kubernetes cluster available (EKS, AKS, GKE, or local)
• kubectl configured and authenticated
• Container registry access (GitHub Container Registry)
• GitHub Actions secrets configured:
  • KUBE_CONFIG (base64 encoded kubeconfig)
  • GITHUB_TOKEN (automatic)
• OAuth credentials ready (Microsoft)
• Domain name purchased (for ingress)
• cert-manager installed in cluster (for TLS)
• Prometheus installed (for monitoring)

Docker Deployment

# Local testing with Docker Compose

Kubernetes Deployment

# 1. Create cluster (if needed)
kind create cluster --name job-info

# 2. Install cert-manager
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.13.0/cert-manager.yaml

# 3. Create secrets
kubectl create secret generic oauth-credentials \
  --from-literal=client-id=YOUR_CLIENT_ID \
