In this article, we will be installing and setting up Docker on a Debian 9 VPS.
Docker is an open-source application that provides lightweight operating-system-level virtualization through the use of containers. It is specially designed to increase the productivity of most IT operations by making virtualization easy to use. Containers are in essence a set of software packages that run as one application that’s isolated from other applications. Developers, System Administrators, and the like take advantage of this feature by spawning containers wherein they can create, deploy, and run applications without needing to create another virtual machine, which greatly affects productivity and cost.
Here are the top reasons why organizations and businesses use Docker:
- Increased developer productivity
- Increased deployment velocity
- Increased IT operation efficiency
- Faster resolution of issues that may arise
- Reduction in IT infrastructure cost
Docker is currently developed and maintained by Docker Inc. and is written using the mainstream Go programming language. It is licensed under Apache License 2.0. As of writing, the latest stable version of Docker is 18.09.5.
There are currently two editions of Docker:
- Docker CE – Community Edition – Open Source Software supported by the community and Docker Inc.
- Docker EE – Enterprise Edition – certified and supported by Docker Inc.
Let’s start installing Docker.
