How to Install Docker and Docker-Compose To Ubuntu 20.04, Azure VM and AWS EC2 instances

First, update your existing list of packages

sudo apt update

Installing Docker

Install the necessary packages to allow apt to use a repository over HTTPS:

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

Add Docker’s official GPG key:

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

Add the Docker repository to your system:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Update the apt package index again:

sudo apt-get update

Finally, install Docker:

sudo apt-get install docker-ce docker-ce-cli containerd.io

Once the installation is complete, you can check the version of Docker that you installed by running:

docker --version

That’s it! Docker should now be installed on your Ubuntu 20.04 system.

Installing Docker Compose

Download the Docker Compose binary into the /usr/local/bin directory with the following command:

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

This command will download the latest version of Docker Compose

Make the Docker Compose binary executable:

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

Verify that Docker Compose was installed correctly by running:

docker-compose --version

That’s it! Docker Compose should now be installed on your Ubuntu 20.04 system.
