Step Snap 1 [docker compose installation]:

For Linux:

# Create the docker cli plugins directory if it doesn't exist
mkdir -p ~/.docker/cli-plugins/

# Download the latest stable version
curl -SL <https://github.com/docker/compose/releases/latest/download/docker-compose-linux-x86_64> -o ~/.docker/cli-plugins/docker-compose

# Make the binary executable
chmod +x ~/.docker/cli-plugins/docker-compose

# Verify the installation
docker compose version

For macOS:

• Docker Compose is included with Docker Desktop for Mac. Just install Docker Desktop from the official website.

For Windows:

• Docker Compose is included with Docker Desktop for Windows. Install Docker Desktop from the official website.

Alternative methods:

1. Using pip (Python package manager):

pip install docker-compose

1. Using apt (on Ubuntu/Debian):

sudo apt update
sudo apt install docker-compose

Note: The recommended way is to install Docker Compose V2 as a Docker CLI plugin (first method shown for Linux). The apt and pip methods might give you older versions.

To verify the installation, run:

docker compose version

Step Snap 2 [docker compose volumes]:

Let me explain the three different formats of Docker volume mounting:

1. hostPath:containerPath[:mode]
