Self-Hosted S3 Static Website with Garage, Nginx, and GitLab CI/CD

Learn how to set up your own S3-compatible static website hosting using Garage, Nginx, and automate deployments with GitLab CI/CD. This guide uses Ansible for infrastructure automation and demonstrates everything with the domain molokov.de.

Prerequisites

• Debian/Ubuntu server with root access
• Domain name (we’ll use molokov.de)
• Ansible installed locally
• GitLab account (for CI/CD)

1. Install Docker with Ansible

First, create an Ansible playbook to install Docker:

Here are production-tested, real-world DevOps automation examples in Python and Bash from reputable DevOps resources.

1. System Resource Monitoring

Monitor CPU and memory usage, sending alerts if thresholds are exceeded:

import psutil

def check_system_resources():
    cpu_usage = psutil.cpu_percent(interval=1)
    memory_usage = psutil.virtual_memory().percent
    if cpu_usage > 80:
        print(f"High CPU usage: {cpu_usage}%")
    if memory_usage > 80:
        print(f"High Memory usage: {memory_usage}%")

check_system_resources()

This type of monitoring is fundamental for production reliability.[1][2]

2. AWS Automation (List S3 Buckets)

Automate AWS tasks like listing all S3 buckets with boto3:

Long time ago we had simple instalation procedure for docker. It can be installed by root or by unpriveleged user. There was some differences.

For now, installing Docker is even simplier than couple years ago. There are 2 main ways:

• 1. Setup a repository for easy update in future (recomended)
• 2. By hand for difficult update in future

Recomended way

Update index of package database:

sudo apt update

Install required packages:

sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

Add Docker’s official GPG key:
