Docker Installation on Ubuntu

We have described Docker widely. It is a by-product of Docker Fig. Docker is a tool that allows managing the distribution of Linux applications running in software containers. It is very difficult to run a Linux command that works with complex containers without putting a load on the system application.

It is an open-source tool with a better and improved version that comes out of the Docker Compose Fig app. In this guide, you will learn how to install Ubuntu Docker.

Why Ubuntu Docker Setup

Docker is highly compatible as it allows users to run tests, distribute and control results as much as they want. Docker is a laboratory that allows a user to fill the container and function in various tasks, allowing him to experiment with new commands.

This tool also supports very cloud computing services, is compatible with applications that use cloud computing services to store data on servers. For example, Microsoft Azure, Puppet, Ansible, OpenStack etc. we can give applications.

It is another Docker feature that attracts the attention of separate storage developers in an isolated environment. The only readable operating system like docker/sys and / proc also works with sensitive mount points.

Installing Docker on Ubuntu

First, update your machine with the latest version using the commands below.

sudo apt-get update
sudo apt-get update

 

sudo apt-get upgrade
sudo apt-get upgrade

 

In this step, you will create the new protocol over HTTPS. Enter the following command on the command line.

protocol over HTTPS
protocol over HTTPS

 

Now you need to import the command when using the correct GPG key with the curl command. To do this, use the following command:

GPG key
GPG key

 

Install Docker

Enter the following command in the terminal window to install Docker.

 install Docker.
install Docker.

 

The Docker service must be set up to run at startup. To do this, type the command below and then press enter.

systemctl start docker.service
systemctl start docker.service

 

systemctl enable docker.service
systemctl enable docker.service

 

Finally, verify that Docker Compose has been successfully installed.

systemctl status docker.serice
systemctl status docker.serice

 

You can start working now but before that, you can check the version with the following command:

docker -v
docker -v

How to Delete Docker?

There are two methods depending on the installation process.

If you installed Docker using the curl command as we showed in this guide, you can remove Docker by deleting its directory with the rm command.

Delete Docker
Delete Docker

 

If you installed Docker with the pip command.

Pip uninstall docker-compose
Pip uninstall docker-compose

Result

Docker is the most effective tool for running Linux commands, as it provides the flexibility to run and manipulate commands for multiple functions in mixed containers. Docker, you can rebuild and delete the containers if they have been changed before or no longer need them. Mixed container configuration with Docker becomes easy and error-free. It allows developers to create creative applications without many commands to deal with.
