HAProxy on Ubuntu 24.04 LTS

The de-facto standard software load balancer. This image boots HAProxy 3.0 on Ubuntu 24.04 LTS with sane, production-oriented defaults — TCP and HTTP load balancing, health checks, and TLS termination for whatever sits behind it.

Get it on Azure Marketplace Deploy on Azure Support & quick start

Version: HAProxy 3.0 (vbernat PPA)Platform: Ubuntu 24.04 LTSPorts: 80 (HTTP frontend), 443 (TCP pass-through frontend)Category: Web & Networking

What's included

HAProxy 3.0 with HTTP/2 and modern TLS support
Layer 4 (TCP) and layer 7 (HTTP) balancing modes
Built-in health checks; runtime API on /run/haproxy/admin.sock (add a loopback stats frontend if you want the HTML page)
Ubuntu 24.04 LTS with automatic security updates
Trusted Launch: Secure Boot + vTPM supported
Pairs with Azure Load Balancer for zone-redundant entry

Quick start

SSH into the VM with the username and key you chose at deploy.
HAProxy runs as a systemd service with a placeholder frontend bound on *:80 and *:443; the main config is /etc/haproxy/haproxy.cfg. The in-image ufw allows 80/443 — open them in the NSG to publish.
Add your frontend/backend definitions, validate with `haproxy -c -f /etc/haproxy/haproxy.cfg`, then `sudo systemctl reload haproxy`. No stats frontend ships — add one bound to 127.0.0.1:8404 if you want it (the runtime API socket is /run/haproxy/admin.sock).

Common use cases

TLS termination and HTTP routing for VM fleets
Blue/green and canary traffic splitting
TCP balancing for databases and brokers
Rate limiting and connection shaping at the edge

Why our images

Freshly rebuilt against the latest security advisories, no shared default credentials, Trusted Launch support, and automatic OS security updates — everything runs in your own Azure subscription under your governance.
