Installing Docker on AWS EC2 Ubuntu Instance

Steps-:

To install Docker on an AWS EC2 Ubuntu instance, follow these steps:

1. Connect to your EC2 instance via SSH or the EC2 console.

2. Update the package list:

sudo apt update && sudo apt upgrade -y

1. Install prerequisite packages:

sudo apt install ca-certificates curl gnupg lsb-release

1. Add Docker's GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

1. Add the Docker repository:

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

1. Install Docker:

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

1. Check the Docker version:

docker -v

1. Add your user to the docker group:

sudo usermod -aG docker $USER

1. Log out and back in or run:

newgrp docker

1. Test Docker by running a container:

docker run hello-world

This installs Docker on your AWS EC2 Ubuntu instance and allows you to run Docker commands without sudo. Let me know if you have any other questions!
