What is Docker?

Docker is an open-source platform for automating the deployment of applications as lightweight, portable, and self-sufficient containers. It bundles applications and all of their dependent requirements into one package or “image” that can be used in different environments without fear of discrepancies between development, staging, and production environments.

Docker enables software to be quickly installed, tested, and deployed without needing to configure a server and configure each component. By deploying the same package or image everywhere, software systems become more resilient to failure, easier to maintain, and simpler to upgrade. As such, Docker has become a popular choice for developers and DevOps teams looking to quickly deploy, scale, and manage their applications.

Installing Docker

Installing Docker is very easy, but the process varies depending on your operating system. For Mac and Windows machines Docker can be installed using official installers, while for Linux machines, it’s best to install Docker using the official repositories.

To install Docker on Mac and Windows, you can download and run the official installers from the Docker website. The installers automatically configure Docker and its associated services, so all you have to do is give it permission and install the necessary components. Once the installers are complete, you should be able to run Docker in the background and access the Docker command-line interface.

To install Docker on Linux, you will need to install a package manager, such as apt-get or yum depending on which distribution you are running. Once the package manager is installed and updated, you can use it to install Docker and the necessary related packages. The exact command varies depending on your distribution. For example, on Ubuntu/Debian you could use the command:

sudo apt-get install docker

Once the packages are installed, you can then use the docker command-line interface to start and manage running containers.

Setting Up Nginx

Nginx is a popular web server and reverse proxy used by many sites and applications on the Internet. To get started, we need to first install Nginx using the same package manager you installed Docker with. For example, on Ubuntu/Debian you could use the command:

sudo apt-get install nginx

Once installed, we need to configure Nginx with our server’s configuration files. These files, which are usually located in the /etc/nginx/ directory, determine how requests are routed and handled by the web server. We can add our own configuration files to this directory or modify the existing files to match our desired setup. Once complete, start the Nginx service with the command:

sudo service nginx start

You should now be able to access your server on port 80. To test this, you can type in your server’s IP in a web browser and you should see the Nginx welcome page.

Installing MySQL

MySQL is a popular open-source relational database management system (RDBMS). To get started, we need to first install MySQL using the same package manager you used to install Docker and Nginx. For example, on Ubuntu/Debian you could use the command:

sudo apt-get install mysql-server

Once installed, you will need to configure the MySQL server. This is done using the mysqld configuration file, which is usually located in the /etc/mysql/ directory. Once configured, start the MySQL server with the command:

sudo service mysql start

You should now be able to log in to the MySQL server and run SQL queries. You can test this by logging in to the MySQL prompt with the command:

mysql -u root -p

Installing PHP

PHP is a popular scripting language used for creating dynamic websites and web applications. To get started, we need to first install PHP using the same package manager you used to install Docker, Nginx, and MySQL. For example, on Ubuntu/Debian you could use the command:

sudo apt-get install php

Once installed, you will need to configure the PHP server using the php.ini configuration file. This file contains settings related to PHP such as the location of the MySQL server and other database connections. Once configured, restart the PHP server with the command:

sudo service php7.0-fpm restart

You should now be able to access your server on port 80 and run PHP scripts in your web browser.

Configuring Docker

Now that we have installed all the necessary components, we can configure Docker to deploy our applications as containers. The exact configuration will depend on your application, but typically will involve creating a Dockerfile, which is used to define the steps for building a container. We can also use Docker Compose to define the steps for deploying a container in an environment. This allows for easy setting up of complex applications consisting of multiple containers.

Once our containers are configured, we can deploy them using the docker-compose command. This will create the necessary containers based on our configuration and deploy them in the desired environment. We can then monitor the containers using the docker command-line interface or a web-based monitoring tool such as cAdvisor.

Conclusion

Docker provides an easy and uniform way for deploying and managing applications in any environment. Installing and configuring Docker is a straightforward process that involves downloading the official installer and running the appropriate commands for the operating system you are using. With Docker, you can quickly and easily create, deploy, and manage applications using self-contained containers.
