# Docker Install Script This script is intended as a convenient way to configure docker's package # repositories and to install Docker Engine, This script is not recommended # for production environments. Before running this script, make yourself familiar # with potential risks and limitations, and refer to the installation manual # at [https://docs.docker.com/engine/install/](https://docs.docker.com/engine/install/) for alternative installation methods. \# # The script: \- Requires `root` or `sudo` privileges to run. \- Attempts to detect your Linux distribution and version and configure your package management system for you. \- Doesn't allow you to customize most installation parameters. \- Installs dependencies and recommendations without asking for confirmation. \- Installs the latest stable release (by default) of Docker CLI, Docker Engine, Docker Buildx, Docker Compose, containerd, and runc. When using this script to provision a machine, this may result in unexpected major version upgrades of these packages. Always test upgrades in a test environment before # deploying to your production systems. \- Isn't designed to upgrade an existing Docker installation. When using the script to update an existing installation, dependencies may not be updated to the expected version, resulting in outdated versions. \# # Source code is available at [https://github.com/docker/docker-install/](https://github.com/docker/docker-install/) \# # Usage # ============================================================================== # # To install the latest stable versions of Docker CLI, Docker Engine, and their # dependencies: 1\. download the script # # $ curl -fsSL [https://get.docker.com](https://get.docker.com) -o install-docker.sh 2\. verify the script's content $ cat install-docker.sh 3\. run the script with --dry-run to verify the steps it executes $ sh install-docker.sh --dry-run 4\. run the script either as root, or using sudo to perform the installation. $ sudo sh install-docker.sh
