1. Install Docker Compose on Ubuntu. As I said previously, in this guide I am going to use Docker compose to simplify installation of home server apps and reduce commandline work. Docker compose is in the Ubuntu repositories but it is quite old, as is the case most of the time. So let's install the latest version of Docker compose on Ubuntu.
  2. 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.

The following config will guide you through a process of changing the docker's default /var/lib/docker storage disk space to another directory. There are various reasons why you may want to change docker's default directory from which the most obvious could be that ran out of disk space. Docker is an application that simplifies the process of managing application processes in containers. In this tutorial, you'll install and use Docker Community Edition (CE) on Ubuntu 18.04. The Docker Weekly is a email newsletter with the latest content on Docker and the event agenda for the upcoming weeks. Meet the Captains Select members of the community that are both experts in their field and are passionate about sharing their Docker knowledge with others.

Build and run container images with Docker.



  • This build can only access files in the home directory. So Dockerfiles and all other files used in commands like docker build, docker save and docker load need to be in $HOME.
  • You can change the configuration of this build by modifying the files in /var/snap/docker/current/.
  • Additional certificates used by the Docker daemon to authenticate with registries need to be added in /var/snap/docker/common/etc/certs.d (instead of /etc/docker/certs.d).

By default, Docker is only accessible with root privileges (sudo). If you want to use docker as a regular user, you need to add your user to the docker group.

Let’s dive into Docker installation steps on Ubuntu 20.04 /20.10 Step 1) Install prerequisites packages for docker Login to Ubuntu 20.04 /20.10 system and run the following apt commands to install docker dependencies. Ubuntu is a Debian-based Linux operating system based on free software. Due to that, docker-compose matchs the docker package version, but is outdated respect to That's why, in Ubuntu 20.04, a docker-compose.yml file with version 3.8 is rejected by the docker-compose Ubuntu package; however, docker-compose file format 3.8 is right one respect to the version. – Peregring-lk Jun 8 '20 at 0:12. Because Docker is open source software it’s not only free to use, but free to adapt, extend, hack, or build on. In this guide I cover installing Docker on Ubuntu 20.04 LTS (Focal Fossa), but the same steps may also work on older versions of Ubuntu, including Ubuntu 18.04 LTS. Step 1 - Install Docker on Ubuntu 20.04. Before creating a Dockerfile, we will install the Docker to our Ubuntu 20.04 system, which is available by default on Ubuntu FocalFossa repository. Update all packages list on the Ubuntu repository and install Docker using the apt command below. Sudo apt update sudo apt install Docker ubuntu 20.04 lts image.

Warning: if you add your user to the docker group, it will have similar power as the root user. For details on how this impacts security in your system, see
