Implementation Notes - Issues #416, #413, #424, #419

Summary

This document summarizes the DevOps infrastructure implementations completed for the AnchorPoint project.

Task 1 - Issue #416: Kubernetes Worker Deployment Manifest

File Location: infra/k8s/workers/deployment.yaml

What Was Implemented

  • ConfigMap: Non-sensitive configuration (LOG_LEVEL, QUEUE_CONCURRENCY, STELLAR_NETWORK, REQUEST_TIMEOUT_MS, METRICS_PORT)
  • Secret: Sensitive credentials template (empty values - must be populated via kubectl create secret or external secret operators)
  • Deployment:
    • RollingUpdate strategy with maxSurge/maxUnavailable
    • Resource requests (100m CPU, 128Mi memory) and limits (500m CPU, 512Mi memory)
    • Liveness probe (/health on port 3002, 30s delay, 10s period)
    • Readiness probe (/health on port 3002, 5s delay, 5s period)
    • Security context (non-root user, no privilege escalation, read-only root filesystem)
  • Service: ClusterIP service exposing HTTP (3002) and metrics (9464) ports

Labels Applied

  • app: anchorpoint
  • component: worker
  • environment: testnet

Manual QA Steps

# 1. Validate YAML syntax
yamllint infra/k8s/workers/deployment.yaml

# 2. Create namespace
kubectl create namespace anchorpoint-testnet --dry-run=client -o yaml | kubectl apply -f -

# 3. Create secrets (replace with actual values)
kubectl create secret generic worker-secrets -n anchorpoint-testnet \
  --from-literal=REDIS_URL='redis://:password@redis:6379' \
  --from-literal=DATABASE_URL='postgresql://...' \
  --from-literal=STELLAR_PASSPHRASE='Test SDF Network ; September 2015' \
  --from-literal=STELLAR_DEPLOYER_SECRET='S...' \
  --from-literal=JWT_SECRET='...'

# 4. Deploy
kubectl apply -f infra/k8s/workers/deployment.yaml -n anchorpoint-testnet

# 5. Verify
kubectl get pods -n anchorpoint-testnet -l app=anchorpoint,component=worker
kubectl get svc -n anchorpoint-testnet anchorpoint-worker-svc
kubectl logs -n anchorpoint-testnet -l app=anchorpoint,component=worker

Task 2 - Issue #413: Terraform AWS RDS PostgreSQL

File Location: infra/terraform/rds/

Files Created

File Description
main.tf RDS instance, security group, subnet group, Secrets Manager integration
variables.tf All configurable parameters with validation
outputs.tf Non-sensitive outputs and Secrets Manager references
terraform.tfvars.example Example configuration (no secrets)

Features Implemented

  • Variables: project_name, environment, region, db_instance_class, db_name, db_username, allocated_storage, max_allocated_storage, subnet CIDRs
  • Multi-AZ: Enabled by default for high availability
  • Automated Backups: 7-day retention, daily backup window
  • Encryption: storage_encrypted = true for data at rest
  • Security Groups: Restricted to app/worker subnet CIDRs only
  • Secrets Manager: Password and endpoint stored securely, never in tfstate
  • Monitoring: CloudWatch logs, Performance Insights enabled

Manual QA Steps

# 1. Initialize
cd infra/terraform/rds
terraform init

# 2. Validate
terraform validate

# 3. Plan
terraform plan -out=tfplan

# 4. Apply
terraform apply tfplan

# 5. Verify RDS
aws rds describe-db-instances --db-instance-identifier anchorpoint-testnet

# 6. Retrieve credentials from Secrets Manager
aws secretsmanager get-secret-value --secret-id anchorpoint/testnet/db-credentials

# 7. Test database connection
psql -h $(terraform output -raw db_endpoint) -U anchorpoint_admin -d anchorpoint

# 8. Cleanup
terraform destroy -auto-approve

Task 3 - Issue #424: Soroban Testnet Deployment Script

File Location: scripts/deploy-soroban-testnet.sh

Features Implemented

  • Environment Variables: SOROBAN_NETWORK_PASSPHRASE, SOROBAN_RPC_URL, SOROBAN_DEPLOYER_SECRET
  • Dry-Run Mode: --dry-run flag validates prerequisites without deploying
  • Contract Build: Builds WASM for all contracts in ./contracts/
  • Deployment: Uses soroban contract deploy with persistent durability
  • Output: Saves deployed contract IDs to deployed-contracts.json
  • Error Handling: set -euo pipefail, logging, exit on failure

Manual QA Steps

# 1. Set environment variables
export SOROBAN_NETWORK_PASSPHRASE="Test SDF Network ; September 2015"
export SOROBAN_RPC_URL="https://soroban-testnet.stellar.org"
export SOROBAN_DEPLOYER_SECRET="S..."

# 2. Validate prerequisites (dry-run)
./scripts/deploy-soroban-testnet.sh --dry-run

# 3. Run deployment
./scripts/deploy-soroban-testnet.sh

# 4. Verify output file
cat deployed-contracts.json

# 5. Check contracts on explorer
curl "https://stellar.expert/explorer/soroban.json?$CONTRACT_ID"

Task 4 - Issue #419: Cert-Manager Let's Encrypt TLS

File Location: infra/k8s/cert-manager/

Files Created

File Description
cert-manager-values.yaml Helm values for cert-manager installation
cluster-issuer.yaml Let's Encrypt staging ClusterIssuer (ACME HTTP-01)
cluster-issuer-prod.yaml Let's Encrypt production ClusterIssuer
certificates.yaml Certificate resources for all hostnames
ingress-tls-annotations.yaml Annotations reference for Ingress TLS
README.md Documentation and QA steps

Features Implemented

  • Staging Issuer: For testing without production rate limits
  • Production Issuer: Ready for live traffic (commented switch instructions)
  • HTTP-01 Challenge: Works with NGINX Ingress Controller
  • Certificates: API, worker/metrics, dashboard, and soroban endpoints
  • HSTS: Security headers included in annotations
  • 90-day certificates: With 15-day renewal window

Manual QA Steps

# 1. Add Helm repo and install cert-manager
helm repo add jetstack https://charts.jetstack.io
helm install cert-manager jetstack/cert-manager \
  -n cert-manager --create-namespace \
  -f infra/k8s/cert-manager/cert-manager-values.yaml

# 2. Apply ClusterIssuer
kubectl apply -f infra/k8s/cert-manager/cluster-issuer.yaml

# 3. Apply Certificates
kubectl apply -f infra/k8s/cert-manager/certificates.yaml

# 4. Check certificate status
kubectl get certificates -n anchorpoint-testnet

# 5. Check cert-manager logs
kubectl logs -n cert-manager -l app=cert-manager

# 6. Verify HTTPS
curl -v https://api.anchorpoint-testnet.example.com

# 7. Switch to production (after testing)
# Update issuerRef.name to 'anchorpoint-prod-issuer' in certificates.yaml

Security Verification

All files have been reviewed to ensure:

  • ✅ No hardcoded secrets, passwords, or credentials in any file
  • ✅ All sensitive values use environment variables or Kubernetes secrets
  • ✅ Terraform uses Secrets Manager instead of exposing in tfstate
  • ✅ Shell script validates all required env vars before running
  • ✅ Kubernetes secrets are empty placeholders (must be created separately)

Lint and Validation Commands

# YAML linting (install yamllint if needed)
yamllint infra/k8s/workers/deployment.yaml
yamllint infra/k8s/cert-manager/*.yaml

# Shell linting (install shellcheck if needed)
shellcheck scripts/deploy-soroban-testnet.sh

# Terraform validation
terraform -chdir=infra/terraform/rds validate

# Kubernetes dry-run (requires kubectl)
kubectl apply --dry-run=client -f infra/k8s/workers/deployment.yaml
