How to install and give permission for docker in shell script

I try install docker like this on EC2 amazon linux and I found this error

# Install Docker
sudo yum install -y docker
sudo systemctl enable docker
sudo systemctl start docker
sudo usermod -aG docker ec2-user

permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.44/containers/json": dial unix /var/run/docker.sock: connect: permission denied

It can fix by control+C and ssh to instance again but I don’t want that method how can I completed one time in shellscript and make it can run without control+C and ssh again

    It looks like you’re outlining the correct steps to install Docker on an Amazon EC2 instance running Amazon Linux. Here’s a concise summary of the process, including some clarifications:

    Manual Installation Steps (If Not Using a Script)
    You can also run the commands manually:

    Remove existing Docker installation

    sudo yum autoremove docker -y

    Install Docker

    sudo yum install docker -y

    Start the Docker service

    sudo service docker start

    Add the ec2-user to the Docker group

    sudo usermod -aG docker ec2-user

    Enable Docker to start on boot

    sudo systemctl enable docker

    Check Docker version

    docker –version

    Important Note
    After running the usermod command, you will need to log out of the EC2 instance and log back in for the group changes to take effect. This is crucial because it allows the ec2-user to run Docker commands without sudo.

    What worked for me was :-

    sudo chmod 777 /var/run/docker.sock

    But before running the above command make sure the user is added in docker group

    sudo usermod -a -G docker <Your_User_Name>
