You can start from the scratch on Amazon Linux ec2 instance for installing Docker by following the step:

Copysudo yum update -y 

sudo amazon-linux-extras install docker 

sudo yum install docker 

sudo service docker start 

sudo usermod -a -G docker ec2-user 

Then logout from the instance and login again to verify the installation of Docker

Copydocker info 

To install Docker-compose follow the below steps:

Copysudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

docker-compose version

This is how I did it, only way I know how: sudo mkdir -p /usr/libexec/docker/cli-plugins sudo curl -SL https://github.com/docker/compose/releases/latest/download/docker-compose-linux-$(uname -m) -o /usr/libexec/docker/cli-plugins/docker-compose sudo chmod +x /usr/libexec/docker/cli-plugins/docker-compose

I looked around for a while before finally tracking this down.
It's here for anyone who finds themselves in the same boat.
The plugin was not installed along with docker. Here is a one-liner:

Edited:

sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-linux-$(uname -m) -o /usr/bin/docker-compose && sudo chmod 755 /usr/bin/docker-compose && docker-compose --version

Affected versions include `<= v25.0.5` and `<= v27.1.0` You can refer to Amazon Linux Security Center ALAS-2024-674 which mentions `AWS is aware of CVE-2024-41110, an issue affecting the Moby open source project, packaged in Amazon Linux as "docker".
