Inception is a system administration project focused on containerization using Docker.
The goal is to build a small infrastructure composed of multiple services running in isolated containers and orchestrated with Docker Compose.

The project consists of:

• A MariaDB database container
• A WordPress container running with PHP-FPM
• An Nginx container acting as a reverse proxy with SSL (HTTPS)
• Persistent volumes for database and website data
• Docker secrets for sensitive credentials

The entire stack runs inside Docker containers without using pre-built images (except base OS images), ensuring full control over configuration and security.

The infrastructure is composed of three main services:

• Nginx (HTTPS only, port 443)
• WordPress + PHP-FPM
• MariaDB

Each service:

• Has its own Dockerfile
• Runs in its own container
• Communicates through a Docker bridge network
• Uses persistent volumes for data storage

Sensitive information (database passwords, admin passwords) is managed using Docker secrets.

Docker allows lightweight containerization compared to traditional virtual machines.
It ensures reproducibility, isolation, and portability of services.

Docker is more efficient for microservice-based architectures like this project.

In this project:

• Database passwords use Docker secrets
• Configuration values use environment variables

This project uses a custom bridge network to isolate services and allow internal communication between containers.

In this project:

• Database and WordPress data use bind mounts for persistence.
• This ensures data remains available even if containers are removed.

• Docker
• Docker Compose
• Linux environment
