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/ 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the script to update an existing installation, dependencies may not be updated to the expected version, resulting in outdated versions.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/

# # 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 -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
