Interdiction :-

Docker has completely changed how we develop software by letting us make small, portable packages called containers. These containers bundle up our applications and all the stuff they need to run. This guide will show you how to install Docker and use its main features. It will help you work more smoothly on your software projects and deploy them faster.

Prerequisites

  • A computer with a 64-bit Ubuntu operating system

  • Administrator privileges (for installation)

  • Basic understanding of terminal commands (not necessary it’s helpful )

Steps :-

step 01 > Update Package Index

To ensure that your local package index is updated, it is recommended to perform this task prior to Docker installation. Simply open a terminal and execute the command below:

sudo apt update

step 02 > Install Dependencies

Before setting up Docker, the installation of a few necessary packages is mandatory. Execute the given command to install these dependencies.

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

step 03 >Add Docker's Official GPG Key

In order to guarantee the genuineness of Docker packages, execute the following command to add Docker's official GPG key onto your system:

curl -fsSL <https://download.docker.com/linux/ubuntu/gpg> | sudo apt-key add -

step 04 > Add Docker Repository

Next, add the Docker repository to your system's software sources

sudo add-apt-repository "deb [arch=amd64] <https://download.docker.com/linux/ubuntu> $(lsb_release -cs) stable"

Step 6 > Install Docker Engine

Finally, install the Docker Engine

sudo apt install docker-ce

Step 7 > Verify Docker Installation

After installing Docker, confirm its proper functioning by checking the version.

docker --version

Step 8 > Run Docker Without sudo (Optional)

In conclusion

Having successfully installed Docker on your Ubuntu system, you are now able to effortlessly containerize and deploy applications using its features.

By following this guide, you will be able to set up Docker on Ubuntu with ease and fully utilize containerization in your projects.
