About Lesson
On macOS and Windows, you should already have Docker Compose installed – it’s set up together with Docker there.
On Linux machines, you need to install it separately.
These steps should get you there:
1. sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
2. sudo chmod +x /usr/local/bin/docker-compose
3. sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
4. to verify: docker-compose --version
