Prerequisites

To ensure that all of the key prerequisites are met:

  • Verify that your system is running a Linux-based operating system. Recommended distributions include Red Hat Enterprise Linux (RHEL), Rocky Linux, and Ubuntu.

  • Verify the Docker installation. If Docker is not installed, run:

    curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

  • Verify the Docker Compose installation:

    Note

    If you are using Docker Compose v1, replace all instances of docker compose with docker-compose in the relevant steps of the installation procedure.

    docker compose

    If the command returns help information, Docker Compose is already installed. Otherwise, install Docker Compose:

    sudo curl -L "https://github.com/docker/compose/releases/download/$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep 'tag_name' | cut -d '"' -f 4)/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
