This project has been created as part of the 42 curriculum by ybenchel

Description:

Inception is a project made to make students of 42 network familiar with the concepts of containerization (the ops in Devops), This project asks us to establish a bunch of containers that run in parallel using docker to build a WordPress website with its own mariadb database and an nginx webserv, as i said this project uses docker and there for were gonna be familiar with most things docker by the end of this project from dockerfiles to docker compose to PID 1 and containers as a concept.

Instructions:

The starting process is very straight forward, Just as in previous projects just use make in this sequence:

1. To build the containers and run them you can type the command "make up".

2. To stop all containers for this environment run "make stop" or "make down" to stop and removed them.

3. To run containers that you stopped using make stop just run "make start".

4. To check the status of all running containers just run "make status".

5. To check the logs file just run "make logs".

Resources:

For the resources i used for this project these are a few of them, Since i didn't rely on one or two things for the whole project:

1. This article right here by youssef is very useful to get most of the needed infos to the start the project like what is a container what is docker etc https://medium.com/@imyzf/inception-3979046d90a0.
2. This one is very helpful to learn containerization by the details the how and why of it, its very helpful https://iximiuz.com/en/posts/container-learning-path/.

Project description:

1. Virtual Machines vs Docker:

First, of-course the difference lies in the fact that Docker is a tool designed to allow us to build, deploy, and run applications in an isolated space, Unlike virtual machines which are more than a tool, they are software made to virtualize everything an OS needs to run, meaning virtualizing the hardware that the OS is going to use.
This is done with a hypervisor, which manages the hardware needed for all virtual machines to run in their own isolated space.
Unlike containers, such as in Docker containers, which need an existing OS to run, containers are lightweight and only use the bare minimum from the kernel while containing all the dependencies and code the application needs to run.

2. Secrets vs Environment Variables:

The main difference is that secrets are designed for sensitive data, such as passwords because they encrypt data, unlike environment variables, which are intended for non-sensitive data.

3.  Docker Network vs Host Network:

Docker network (Bridge) is an isolated network requiring port mapping, while the host network makes containers share the hosts network directly.

4. Docker Volumes vs Bind Mounts:

The main deference is that bind mounts use existing volumes on the host machine to store data, unlike docker volumes which use pre-made default docker paths on the host like /var/lib/docker/volumes/ to store data.
