How to install docker in ubuntu 18.04 : Easy method!

Are you looking for how to install docker in Ubuntu 18.04? Here’s how we do it. 

Docker is an application that simplifies the process of managing application processes in containers.

At Bobcares, we often get requests from our customers to install docker in Ubuntu as part of our Server Management Services.

Today, let’s get into the details on how our Support Engineers install and fix related errors.


How we install docker in Ubuntu?

Frequently many customers approach us for installing docker in Ubuntu. Our Support engineers help the customers in installing it and fix any related errors.

Now, let’s see how our Support Engineers install the docker in Ubuntu.


Using Default Repositories

Initially, we updated software repositories by running the following command in the terminal.

sudo apt-get update

After that, we uninstalled any old Docker software before proceeding via the below command.

sudo apt-get remove docker docker-engine

Thereafter, we installed Docker on Ubuntu by running the command in the terminal.

sudo apt install

Then we started and enabled the docker service.

sudo systemctl start docker
sudo systemctl enable docker

Finally, we verified the installed Docker version number.

docker --version


Install Docker from Official Repository

Another alternate method in which we install the docker is as following

After updating the local database using the following command,

sudo apt-get update

We then download Dependencies.

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

Here the dependencies are :

  • apt-transport-https: Allow package manager to transfer files and data over https.
  • ca-certificates: Allows to check security certificates.
  • curl: tool for transferring data.
  • software-properties-common: Adds necessary scripts for managing software.

Thereafter Add Docker’s GPG Key. GPG key is a security feature.

curl -fsSL | sudo apt-key add –

Then, installed the Docker repository via the following command.

sudo add-apt-repository "deb [arch=amd64] $(lsb_release -cs) stable"

We then Updated the repositories that we just added.

sudo apt-get update

To install the latest version of docker:

sudo apt-get install docker-ce

For installing a particular version, add the version in place of the following command.

sudo apt-get install docker-ce=<VERSION>

Thus, we easily installed the docker.
