Docker is a combination of platform as a service products that use virtualization to provide software in packages called containers which can communicate with each other through well-defined channels. This tutorial focuses on Installing the latest Docker release on Ubuntu 20.04 LTS Focal Fossa.
In this tutorial you will learn:
This tutorial will provide you with simple to follow steps on how to install Docker on Fedora 31 Linux.
In this tutorial you will learn:
Install the latest Docker release on Ubuntu 18.04
Ubuntu 18.04 Bionic Beaver
A working install of Ubuntu 18.04 with root privileges
sudo commandDocker has revolutionized how web applications are hosted and servers are run. Docker containers allow server administrators to compartmentalize their applications like virtual machines, but containers are much lighter weight, are easier to manager, and add less overhead.
Installing Docker on Ubuntu is very simple. Because Ubuntu is a popular choice for the cloud, the entire process has been streamlined to a science.
Following this tutorial you will be able to create a LAMP environment using the Docker technology.

Docker is an open source project aimed at providing software inside containers. You can think of a container as a sort of “package”, an isolated environment which shares the kernel with the host machine and contains everything the application needs. All containers are built using images (the central images repository for them being Dockerhub).
In this tutorial, we will see how to create a LAMP stack based on dockerized components: following the “one service per container” philosophy, we will assemble the environment using docker-compose, a tool to orchestrate container compositions.
The objective is to install Kubernetes on Ubuntu 18.04 Bionic Beaver Linux
Privileged access to your Ubuntu System as root or via sudo command is required.
In this guide we will be configuring the simplest possible Kubernetes cluster consisting of two nodes. The first node with hostname kubernetes-master will act as the master node.
The second node with hostname kubernetes-master also running Ubuntu 18.04 will be a slave node simply joining the Kuberneets cluster. Once we get the Kubernetes cluster up and running as a proof of concept we will deploy a Nginx server container.
The latest release of the RHEL 8 / CentOS 8. Red Hat has built its own tools, buildah and podman, which aim to be compatible with existing docker images and work without relying on a daemon, allowing the creation of containers as normal users, without the need of special permissions (with some limitations: e.g. at the moment of writing, it’s still not possible to map host ports to the container without privileges).
Some specific tools, however, are still missing: an equivalent of docker-compose, for example does not exists yet. In this tutorial we will see how to install and run the original Docker CE on Rhel8 by using the official Docker repository for CentOS7.
In this tutorial you will learn:
Even if Red Hat has developed podman and buildah, its own tools to work with containers, which come with some important advantages like a daemonless architecture, you may want to continue using the original Docker software on Fedora. In this tutorial we will explore the options we have on the latest release of the distribution to do so, and will see how to apply the needed fixes for Docker to work correctly.

LAMP is the software stack on which probably the majority of websites run. Linux represents the foundation of the stack, and the traditional implementation includes Apache as the web server, the MySQL database, and PHP as the server-side programming language. There are, however, many possible variations: MariaDB, for example, is often used in place of MySQL, of which it is a fork, and other programming languages, as Python or Perl can be used instead of PHP. In this article we will see how to implement a basic LAMP stack using docker and the docker-compose utility.
In this tutorial you will learn:
Compose is a feature for setting up and running multi-container Docker applications. With a single command, you can create and start all the services from your configuration. To learn more about Compose see How To Launch Containers With Docker Compose. The objective of this short guide is to install docker-compose on Ubuntu 20.04 Focal Fossa Linux Server/Desktop.
