Installing n8n in Docker with HAProxy: A Clear Guide for Beginners

2025-07-02

Hi friends! Today, we’re diving into the world of automation and deploying n8n — a powerful workflow automation tool. We’ll install it in Docker, and use HAProxy as a reliable reverse proxy to expose it to the internet.

This guide is created especially for beginners. We’ll go step by step, explaining every command so you not only do it, but also understand how everything works.

Why do we even need HAProxy?

You could just expose n8n’s ports to the internet, right? Yes, but that’s unsafe and inconvenient. HAProxy acts as both a guard and a dispatcher:

Redirecting All Container Traffic via SOCKS Proxy Using tun2socks

2025-06-17

Sometimes it becomes necessary to route all outgoing traffic from a specific container through a proxy server. This can be useful for ensuring anonymity, bypassing geo-restrictions, or for testing network configurations. In this article, we’ll look at how to set up such a system using the tun2socks utility and iptables rules, as well as how to manage this process with systemd.

What is tun2socks?

tun2socks is a powerful tool that allows you to redirect network traffic intended for a TUN device through a SOCKS proxy. It creates a virtual network interface (TUN device), and all traffic flowing through it is encapsulated into a SOCKS connection. This is especially convenient when direct application-level proxying is impossible or undesirable.

Response: Thanks for the review! Glad to help

I want to express my deep gratitude to the specialist who set up SEO-friendly URLs for me on OpenCart. Configuring them turned out to be easy and simple, and I'm glad I finally found a professional who did everything well and without unnecessary complications. Before this I went through four specialists, and each time there were issues with the setup, but this person handled the task perfectly.

I needed to resolve an SSL certificate issue on a server where the certificate had been issued through Nginx Proxy Manager. Mikhail clarified all the details of my setup and requested access to assess the feasibility of solving the issue, since he hadn't worked with that service before. He quickly figured it out and fixed my problem. Perfect cooperation)
