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 the advanced bug fixing tasks about DevSecOps in Terraform manifests for GitLab CI/CD pipelines, now with concrete example snippets and solutions:

1. Production Pipeline: Misconfigured Terraform State Backends

Problem:
The terraform apply step in your production GitLab CI pipeline fails with errors related to locked state files or concurrent access conflicts.

Example and Solution:

In your Terraform manifest (e.g., backend.tf), configure the backend with proper state locking using AWS S3 and DynamoDB for locking:

Here are three advanced bug examples and solutions related to modern GitLab CI/CD DevSecOps pipelines with security best practices and explanations. These focus on common pitfalls and necessary configurations for secure, robust pipelines using .gitlab-ci.yml.

Advanced Bug Example 1: Secrets Leakage via Unprotected Variables

Buggy .gitlab-ci.yml snippet:
