🚀 Deployment

Automatic Deployment (Current Setup)

The project uses Gitea Actions for CI/CD. Every push to main triggers:

1. Build: Docker image built for linux/arm64
2. Push: Image pushed to registry.infra.mintel.me
3. Deploy: SSH to production server, pull and restart containers

Workflow: .gitea/workflows/deploy.yml

Required Secrets (configure in Gitea repository settings):

• REGISTRY_USER - Docker registry username
• REGISTRY_PASS - Docker registry password
• ALPHA_SSH_KEY - SSH private key for deployment
• NEXT_PUBLIC_UMAMI_WEBSITE_ID - Analytics ID
• NEXT_PUBLIC_UMAMI_SCRIPT_URL - Analytics script URL
• SENTRY_DSN - Error tracking DSN

Manual Deployment

# SSH into production server
ssh deploy@alpha.mintel.me

# Navigate to project
cd /home/deploy/sites/klz-cables.com

# Pull latest image and restart
docker compose pull
docker compose up -d --force-recreate --remove-orphans
docker image prune -f

Or use the convenience script:

bash scripts/deploy-webhook.sh

Architecture

Client → Traefik (TLS) → Varnish (Cache) → Next.js App

Domains:

• klz-cables.com - Production
• www.klz-cables.com - Production (www)
• staging.klz-cables.com - Staging

Services:

• app: Next.js application (port 3000)
• varnish: HTTP cache layer
• traefik: Reverse proxy (external)

For detailed deployment documentation, see docs/DEPLOYMENT.md.
