Update package repository information
sudo apt-get update
Running sudo apt-get update is an important step before installing or upgrading packages on your system because it ensures that you have the most up-to-date information about available packages.
Without updating the package index, you might not see the latest versions of software or be able to install new packages that have been added to the repositories since the last update.
Download Docker-compose binary
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
Output:
The command downloads the Docker Compose binary for your specific operating system and architecture from GitHub and places it in the /usr/local/bin directory, making it accessible system-wide.
Make it executable
sudo chmod +x /usr/local/bin/docker-compose
Output
The command sudo chmod +x /usr/local/bin/docker-compose is making the Docker Compose binary executable.
This step is necessary because, by default, files downloaded from the internet are not executable for security reasons.
By granting execute permission, you enable the system to run the Docker Compose binary as a program when you use it in the command line.
Verify the installation
Version
docker-compose --version
Output
Through executable path
which docker-compose
Output
Test
docker-compose up
Since I did not provide any arguments after the preposition up, it should return something like this.
Done

You've made it!
