Docker

There was a task to get n8n, redis and the database working. I had previously ordered from another contractor, it kept breaking all the time. Ordered from Mikhail, the next day everything started working fast, like clockwork!

In the previous article, we deployed a basic Jitsi Meet server using Docker.
Now let’s look at how to secure your server, enable authentication, and optimize performance for stable video calls.

Authentication: Invite-Only Access

By default, Jitsi Meet allows anyone to create rooms. To restrict access — enable Secure Domain.

1. Open the .env file and find the Prosody (XMPP server) section.

   ENABLE_AUTH=1
   AUTH_TYPE=internal
   

Here, internal means that users will be stored locally.

Want to set up your own fully private video conferencing server?
Jitsi Meet is a great choice, and installing it with Docker is the fastest and most reliable way. This article provides a step-by-step guide to get your server up and running in just a few minutes.

Step 1: Preparation

Before installing, make sure you have:

• A Linux server (e.g., Ubuntu).
• A domain name pointing to your server’s IP (e.g., meet.your-domain.com).
• Installed Docker and Docker Compose.

👉 If Docker isn’t installed yet — use the instructions from the previous article.

Thank you for the quick and good work. Everything was done promptly and as needed!

Introduction

Unlike Caddy, which focuses on simplicity, Traefik (pronounced Traffic) was built to solve one specific task: routing traffic in dynamic environments.

It is a reverse proxy and load balancer designed specifically for Docker, Kubernetes, and other orchestrators. The main difference from Nginx is not static configuration, but the ability to automatically discover and serve services.

Key Concepts: Dynamic Configuration

The philosophy of Traefik is built on the principle of Service Discovery.

Introduction

Logrotate is a powerful tool for log management in Linux, but its interaction with Docker has its own specifics. This guide explains how to properly use logrotate with Docker containers and when it’s better to rely on Docker’s built-in log management tools.

Docker Containers and Logs

Docker collects logs from the standard output streams (stdout and stderr) of containers and, by default, stores them as JSON files:

/var/lib/docker/containers/\<container\_id>/\<container\_id>-json.log

If a container generates a lot of logs, these files can take up gigabytes and quickly consume all available disk space.

Introduction

In a world where setting up a web server often requires studying complex configuration files, Caddy offers a radically different approach. It is a modern, multifunctional web server, reverse proxy, and certificate authority in one package.

Caddy was created with a single goal: to provide maximum simplicity. If you are tired of the redundancy of Nginx or Apache, then Caddy is what you’re looking for. Its main “killer feature” is fully automatic SSL certificate management, making it an indispensable tool for developers.

Quick fix for the problem, I recommend Mikhail as a contractor to everyone! I tried to assemble a similar configuration myself and following advice from neural networks, which resulted in a lot of wasted effort and money (due to server downtime). So my advice in the end — turn to professionals, it will be cheaper =) Thanks to Mikhail for his professionalism.

Response: Thank you for the review! Glad to help!

Mikhail completed the setup of another VPS. Quickly, professionally bypassing certain limitations of hosting providers.

Introduction: A Hidden Network Issue

Developers and system administrators using servers on the OpenStack platform (for example, the C*-M*-D* hosting plans from reg.ru) sometimes encounter mysterious network problems. The internet seems to work, but when trying to transfer large amounts of data or establish connections to certain services, requests may hang or fail due to timeouts.

The provider explains this issue as a feature of their infrastructure:

Servers on the OpenStack platform use VxLAN technology, which reserves 50 bytes for service information. Because of this, the maximum transmission unit (MTU) on the server’s main network interface (ens3) is 1450 bytes.
