Introduction> Introduction # Docker is an application that simplifies the process of managing application processes in containers. Containers let you run your applications in resource-isolated processes. They’re similar to virtual machines, but containers are more portable, more resource-friendly, and more dependent on the host operating system.

Introduction> Introduction # Over the past few years, Docker has become a frequently used solution for deploying applications thanks to how it simplifies running and deploying applications in ephemeral containers.

Introduction> Introduction # This tutorial shows how to deploy Nginx in a Docker container. By containerizing Nginx, we cut down on our sysadmin overhead. We will no longer need to manage Nginx through a package manager or build it from source.

Introduction> Introduction # Docker Compose makes dealing with the orchestration processes of Docker containers (such as starting up, shutting down, and setting up intra-container linking and volumes) really easy. This article provides a real-world example of using Docker Compose to install an application, in this case WordPress with PHPMyAdmin as an extra.

Introduction> Introduction # Containerization is the process of distributing and deploying applications in a portable and predictable way. It accomplishes this by packaging components and their dependencies into standardized, isolated, lightweight process environments called containers.

Introduction> Introduction # When you create a Docker container, it is assigned a universally unique identifier (UUID). These are essential to avoid naming conflicts and promote automation without human intervention. They effectively identify containers to the host and network.

Introduction> Introduction # In general, Docker containers are ephemeral, running just as long as it takes for the command issued in the container to complete. By default, any data created inside the container is only available from within the container and only while the container is running.

Introduction> Introduction # If you are actively developing an application, using Docker can simplify your workflow and the process of deploying your application to production. Working with containers in development offers the following benefits:

Introduction> Introduction # Docker is a great tool for automating the deployment of Linux applications inside software containers, but to really take full advantage of its potential it’s best if each component of your application runs in its own container.

Introduction> Introduction # Docker is a great tool for deploying your servers. Docker even has a public registry called Docker Hub to store Docker images. While Docker lets you upload your Docker creations to their Docker Hub for free, anything you upload is also public.

Introduction> Introduction # Docker Machine is a tool that makes it easy to provision and manage multiple Docker hosts remotely from your personal computer. Such servers are commonly referred to as Dockerized hosts, and as a matter of course, can be used to run Docker containers.

Introduction> Introduction # Docker simplifies the process of managing application processes in containers. While containers are similar to virtual machines in certain ways, they are more lightweight and resource-friendly. This allows developers to break down an application environment into multiple isolated services.

Introduction> Introduction # Kubernetes is a powerful open-source system, initially developed by Google and supported by the Cloud Native Computing Foundation (CNCF), for managing containerized applications in a clustered environment. It aims to provide better ways of managing related, distributed components and services across varied infrastructure.
