Hello readers, in this article we are going to discuss about docker compose and building LAMP Architecture with Docker Compose.

What is Docker Compose

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

YAML File

YAML stands for YAML ain't markup language, which is a data serialization language that is often used for writing configuration files. YAML will store data in key value pairs, YAML file is a space indented.

Docker Compose Installation

To install docker compose on the Linux machine, please follow the steps below

• Connect to your Linux Machine

• Get root privilege's => sudo su -

• Run the following commands

• curl -SL https://github.com/docker/compose/releases/download/v2.11.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
  

• ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
  

• To verify docker-compose installation, run the following command

# docker compose --version

LAMP Architecture

LAMP stands for Linux, Apache, MySQL, and PHP. Together, they provide a proven set of software for delivering high-performance web applications.

• Create a docker compose file for setting up LAMP Architecture

# vim docker-compose.yml

---

version: '3'

services:
 mysql:
  image: mysql
  environment:
   MYSQL_ROOT_PASSWORD: sql
  networks:
    - host
 apache:

• To run the docker-compose.yml file in a detached mode, run the following command

# docker-compose up -d
