🚀 Deployment

Automatic Deployment (Current Setup)

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

1. Build: Docker image built for linux/arm64 with branch-specific build args
2. Push: Image pushed to registry.infra.mintel.me with commit SHA tag
3. Deploy: SSH to production server, pull and restart containers using branch-specific .env files

Workflow: .gitea/workflows/deploy.yml

Branch Deployments:

• main branch: Deploys to production using .env.prod
• staging branch: Deploys to staging using .env.staging

Environment Overrides: The CI/CD workflow supports STAGING_-prefixed secrets (e.g., STAGING_NEXT_PUBLIC_BASE_URL) to override default secrets when deploying the staging branch.

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_BASE_URL - Application base URL (e.g., https://klz-cables.com)
• UMAMI_WEBSITE_ID - Analytics ID
• UMAMI_API_ENDPOINT - Analytics API endpoint (formerly NEXT_PUBLIC_UMAMI_SCRIPT_URL)
• SENTRY_DSN - Error tracking DSN
• MAIL_HOST, MAIL_PORT, MAIL_USERNAME, MAIL_PASSWORD, MAIL_FROM, MAIL_RECIPIENTS - Email configuration

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) → 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)
• traefik: Reverse proxy (external)

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

• Clear .next cache: rm -rf .next

Missing Modules

• Run npm install --legacy-peer-deps
• Check package.json dependencies
