2.1 Docker Compose on Windows
Docker Compose is a tool for defining and running multi-container Docker applications. Installing Docker Compose depends on the operating system you are using. In this lecture, we'll go through the steps for installing Docker Compose on different operating systems: Linux, macOS, and Windows.
Installing Docker Compose on Windows
Step 1: Install Docker Desktop
On Windows, Docker Compose is also installed alongside Docker Desktop. So ideally, it's already installed. If for some reason you're reading this lecture without having Docker installed, go download Docker Desktop from the official Docker website and install it.
Step 2: Launch Docker Desktop
Launch Docker Desktop from the "Start" menu. After installing and starting Docker Desktop, Docker Compose will be available from the command line.
Step 3: Verify the Installation
Open the Command Prompt or PowerShell and check that Docker Compose is installed and works correctly.
docker compose --version
Note! Other command variants:
docker-compose --version
docker compose version
You should see the version information for Docker Compose.
2.2 Docker Compose on macOS
Installing Docker Compose on macOS
Step 1: Install Docker Desktop
On macOS, Docker Compose is installed together with Docker Desktop. So ideally it’s already installed. If for some reason you are reading this lecture without having Docker installed, go ahead and download Docker Desktop from Docker’s official website and install it.
Step 2: Launch Docker Desktop
Launch Docker Desktop from your applications. After that, Docker Compose will be available from the command line.
Step 3: Verify Installation
Make sure Docker Compose is installed and working correctly.
docker compose --version
You should see the version information of Docker Compose.
Caution! Alternative commands:
docker-compose --version
docker compose version
2.3 Docker Compose on Linux
Installing Docker Compose on Linux
Step 1: Install Docker
Before installing Docker Compose, make sure Docker is already installed on your system. If Docker is not installed, run the following commands:
sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install -y docker-ce
Step 2: (Optional) Configure Docker to run without sudo
To avoid using sudo for every Docker command, add the current user to the Docker group:
sudo usermod -aG docker $USER
Step 3: Install Docker Compose
Just run the command
sudo apt-get install docker-compose-plugin
Step 4: Verify Installation
Make sure Docker Compose is installed and functioning correctly.
docker compose --version
You should see something like:
Docker Compose version v2.12.2
