Docker on x86 / AMD64
Standard cloud VMs. Native, not emulated.
The z4jdev/z4j Docker image is built natively for linux/amd64, so it runs at full speed on any standard cloud VM (AWS EC2, GCP, Azure, Hetzner, DigitalOcean) without QEMU emulation. Same image works under docker compose, systemd, ECS, Cloud Run, Fly, Railway, and Kubernetes. The bare metrics endpoint, audit log verification, and notification channels are identical to the pip tier.
Ships with
- Multi-arch manifest under z4jdev/z4j; AMD64 is the default for all common cloud providers
- Single image carries brain + dashboard + migrations; one container is the whole control plane
- Postgres recommended in this tier; Z4J_DATABASE_URL points at any reachable Postgres
- Works behind Caddy, nginx, Traefik, Cloudflare Tunnel; auto-promotes to production mode when Z4J_PUBLIC_URL is HTTPS and Z4J_ALLOWED_HOSTS is set
Highlights
- Native AMD64 build; no QEMU translation overhead
- Versioned tags (z4jdev/z4j:1.5.0) plus rolling latest tag
- GitHub Actions release pipeline publishes new tags within minutes of a release
