# Introduction

Docker (opens new window) is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. Docker can also be used for defining and running multi-container Docker applications using the Docker Compose tool.

With the help of Docker Compose, you can define containers to be built, their configuration, links, volumes, ports, etc., in a single file, and it gets launched by a single command. You can also add multiple servers and services just by adding them to the Docker Compose configuration file. This configuration file is in YAML (opens new window) format.

# Application Data and Database Volume Persistence

It is recommended to keep your application files and database data volume on the Docker host and mount them on the running container. This ensures that the application and database data persistence even in the case of containers' failure or termination. In this way, even if you destroy containers, your data won't get lost unless you remove them forcefully. This compose configuration file mounts the application directory app and database volume dbvolume from the host to running Docker containers at the time of containers' launch.

# Docker Setup for Krayin

You can configure Krayin using Docker in two different ways:

Using Krayin Docker Image from Docker Hub
Using Krayin GitHub Docker Repository

Both approaches allow you to set up the application quickly, managing all system requirements like Apache, MySQL, and PHPMyAdmin within isolated containers. Below is a detailed guide for each method.

# 1. Using Krayin Docker Image from Docker Hub

Follow the steps below to set up Krayin using Docker Hub. This approach provides a pre-configured Docker image of Krayin, allowing for a quick and easy installation.

# Step 1: Pull Krayin Docker Image

To pull the Krayin Docker image from Docker Hub, use the following command:

docker pull webkul/krayin:2.0.1

# Step 2: Run a New Container

Once the image is pulled, you can run a new Docker container using the command below. This will bind your local port 80 to the container’s port 80, so Krayin can be accessed via the browser.

docker run -it -d -p 80:80 webkul/krayin:2.0.1

Note: If port 80 is already in use, you can try using a different port. For example, you can map port 8082 on your local machine to port 80 in the container by running the following command:
docker run -it -d -p 8082:80 webkul/krayin:2.0.1
After this, you can access the application at http://localhost:8082/ instead of http://localhost:80

# Step 3: Access Krayin in Your Browser

After the container is up and running, open your browser and navigate to http://localhost. This will load the Krayin setup.

Use the following credentials to log in to the Krayin admin panel:

Admin Username: [email protected]
Admin Password: admin123

# 2. Using Krayin GitHub Docker Repository

# System Requirements

The Krayin GitHub Docker repository automatically handles the system requirements for running Krayin, including the necessary Apache and MySQL configurations. Before proceeding, ensure that you have the latest version of Docker and Docker Compose installed. You can find installation instructions for your operating system at the following links:

# Docker Configuration

Adjust Ports and Paths
Open the docker-compose.yml file and configure the ports for Apache, MySQL, and PHPMyAdmin. You can also specify the volumes and MySQL credentials. Here's an example configuration:

version: '3.1'

 services:
     krayin-php-apache:
         build:
             args:
                 container_project_path: /var/www/html/
                 uid: 1000 # add your uid here
                 user: $USER
             context: .
             dockerfile: ./Dockerfile
         image: krayin-php-apache
         ports:
             - 80:80 # adjust your port here, if you want to change
         volumes:
             - ./workspace/:/var/www/html/

     krayin-mysql:
         image: mysql:8.0
         command: --default-authentication-plugin=mysql_native_password
         restart: always
         environment:
             MYSQL_ROOT_HOST: '%'
             MYSQL_ROOT_PASSWORD: root
         ports:
             - 3306:3306 # adjust your port here, if you want to change
         volumes:
             - ./.configs/mysql-data:/var/lib/mysql/

     krayin-phpmyadmin:
         image: phpmyadmin:latest
         restart: always
         environment:
             PMA_HOST: krayin-mysql
             PMA_USER: root
             PMA_PASSWORD: root
         ports:
             - 8080:80 # adjust your port here, if you want to change

 volumes:
     mysql-data:

Running the Setup
After adjusting the configurations, execute the following command to start the Docker containers:
```
sh setup.sh
```
