ft_services is an individual school project at 42 Paris campus. The purpose of this project is to use Kubernetes to virtualize a network and set a production environment.

For learning purposes only, not intended for production.

• Alpine Linux
• Kubernetes
• Docker
• MetalLB
• Nginx
• FTPS
• WordPress
• phpMyAdmin
• MariaDB (MySQL)
• Grafana
• InfluxDB

We run our project on Linux Alpine which uses the Linux kernel.
Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busybox.
This distribution is particularly suitable, due to its lightness, for the creation of Docker container images.
More details here.

Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.
More details here Or Here.

Kubernetes resource objects is a high-level overview of the basic types of resources provide by the Kubernetes API and their primary functions.
For a better understanding of Kubernetes Object Management, you'll find More informations here.
This link will be helpful for create your own YAML files.
Check the kubernetes objects usage of this project here.

Minikube is a tool to facilitate the local execution of Kubernetes. Minikube runs a single-node Kubernetes cluster in a virtual machine (VM) on your laptop.
More details here.

Nginx is open source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. It started out as a web server designed for maximum performance and stability. In addition to its HTTP server capabilities, NGINX can also function as a proxy server for email (IMAP, POP3, and SMTP) and a reverse proxy and load balancer for HTTP, TCP, and UDP servers.

MetalLB allows access to your Kubernetes services from outside the Kubernetes cluster. You configure access by creating a collection of rules that define which inbound connections reach which services.

if you have difficulty to understand the interaction between Kubernetes MetalLB, please look at this link.

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. More details here.
For more informations, you can also check my project ft_server about docker containers and docker files usage Here.

WordPress (WordPress.org) is a content management system (CMS) based on PHP and MySQL that is usually used with the MySQL or MariaDB database.

PhpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the Web. It will help to link our databases with the rest ouf our services.

MySQL is a freely available open source Relational Database Management System(RDBMS) that uses Structured Query Language (SQL). WordPress requires MySQL to store and retrieve all of its data including post content, user profiles, and custom post types.

FTPS is a name used to encompass a number of ways in which FTP software can perform secure file transfers. Each involves the use of a security layer below the standard FTP protocol to encrypt data.

Grafana is a multi-platform open source solution for running data analytics, pulling up metrics that make sense of the massive amount of data, and monitoring apps through customizable dashboards. Available since 2014, the interactive visualization software provides charts, graphs, and alerts when the service is connected to supported data sources.

InfluxDB is an open-source time series database(TSDB) developed by InfluxData. It is written in Go and optimized for fast, high-availability storage and retrieval of time series data in fields such as operations monitoring, application metrics, Internet of Things sensor data, and real-time analytics. It also has support for processing data from Graphite. In our project, InfluxDB will stock the necessairy data for running Grafana application.

Telegraf is a metric collection agent, only one agent is required per VM. This agent knows how to collect metrics exposed in Prometheus format and offers two methods of retrieving metrics, via:

push : the metric is pushed into Telegraf by the component that exposes it pull : Telegraf retrieves the metric by interrogating the component that exposes it (the most used mode)3

The setup script check if : Docker, VirtualBox, minikube and kubectl are installed for the VM. If not the script installs it for you. For running the script one 42 Mac, run ini_docker.sh script.

• Setup :

# Start the setup for 42Mac
bash setup.sh 42mac

# Start the setup for VM
bash setup.sh vm

# Remove all containers
./setup.sh clean

• FTPS on port 21
• MySQL on port 3306
• Wordpress on port 5050
• Phpmyadmin on port 5000
• Grafana on port 3000
• InfluxDB on port 8086
• Nginx on port 80(HTTP), 443 (SSL) and 22 (SSH)

School project done at 42 Paris.
