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+# script to update an existing installation, dependencies may not be updated +# to the expected version, resulting in outdated versions.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 +# +# Command-line options +# ============================================================================== +# +# --version +# Use the --version option to install a specific version, for example: +# +# $ sudo sh install-docker.sh --version 23.0 +# +# --channel +# +# Use the --channel option to install from an alternative installation channel. +# The following example installs the latest versions from the "test" channel, +# which includes pre-releases (alpha, beta, rc): +# +# $ sudo sh install-docker.sh --channel test +# +# Alternatively, use the script at https://test.docker.com, which uses the test +# channel as default. +# +# --mirror +# +# Use the --mirror option to install from a mirror supported by this script. +# Available mirrors are "Aliyun" (https://mirrors.aliyun.com/docker-ce), and +# "AzureChinaCloud" (https://mirror.azure.cn/docker-ce), for example: +# +# $ sudo sh install-docker.sh --mirror AzureChinaCloud +# +# --setup-repo +# +# Use the --setup-repo option to configure Docker's package repositories without +# installing Docker packages.
