Installing Docker on Ubuntu 18

Installing Docker on Ubuntu 18

Having a docker runtime saves a lot of time for developers while they setup their personal pc. Once the docker runtime is available, services for database, cache, messaging can be just started in couple of seconds instead of reading though individual documentation & following a step-by-step guide. This post is about installing the docker on ubuntu:

Update Software Repositories

It is recommended to update the local repo with latest revisions of the software before we start with any installation. This is done so that we get access to the latest bug fixes & security updates:

sudo apt-get update

Install Docker

If you already have docker installed, it is better to uninstall the same before going ahead with installation of the newer version:

sudo apt-get remove docker docker-engine
sudo apt install

Start Docker Service

Let's start the service now:

$ sudo systemctl start docker
$ sudo systemctl enable docker
Synchronizing state of docker.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable docker

$ docker --version
Docker version 18.09.7, build 2d0083d
