#!/bin/sh set -e # Docker Engine for Linux installation 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# script to update an existing installation, dependencies may not be updated # to the expected version, resulting in outdated versions.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 # # Command-line options # ============================================================================== # # –version <VERSION> # Use the –version option to install a specific version, for example: # # $ sudo sh install-docker.sh –version 23.0 # # –channel <stable|test> # # 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 <Aliyun|AzureChinaCloud> # # 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 # # ============================================================================== # Git commit from https://github.com/docker/docker-install when # the script was uploaded (Should only be modified by upload job): SCRIPT_COMMIT_SHA=”6d9743e9656cc56f699a64800b098d5ea5a60020″ # strip “v” prefix if present VERSION=”${VERSION#v}” # The channel to install from: # * stable # * test # * edge (deprecated) # * nightly (deprecated) DEFAULT_CHANNEL_VALUE=”stable” if [ -z “$CHANNEL” ]; then CHANNEL=$DEFAULT_CHANNEL_VALUE fi DEFAULT_DOWNLOAD_URL=”https://download.docker.com” if [ -z “$DOWNLOAD_URL” ]; then DOWNLOAD_URL=$DEFAULT_DOWNLOAD_URL fi DEFAULT_REPO_FILE=”docker-ce.repo” if [ -z “$REPO_FILE” ]; then REPO_FILE=”$DEFAULT_REPO_FILE” fi mirror=” DRY_RUN=${DRY_RUN:-} while [ $# -gt 0 ]; do case “$1″ in –channel) CHANNEL=”$2″ shift ;; –dry-run) DRY_RUN=1 ;; –mirror) mirror=”$2″ shift ;; –version) VERSION=”${2#v}” shift ;; –*) echo “Illegal option $1” ;; esac shift $(( $# > 0 ? 1 : 0 )) done case “$mirror” in Aliyun) DOWNLOAD_URL=”https://mirrors.aliyun.com/docker-ce” ;; AzureChinaCloud) DOWNLOAD_URL=”https://mirror.azure.cn/docker-ce” ;; “”) ;; *) >&2 echo “unknown mirror ‘$mirror’: use either ‘Aliyun’, or ‘AzureChinaCloud’.” exit 1 ;; esac case “$CHANNEL” in stable|test) ;; edge|nightly) >&2 echo “DEPRECATED: the $CHANNEL channel has been deprecated and is no longer supported by this script.” exit 1 ;; *) >&2 echo “unknown CHANNEL ‘$CHANNEL’: use either stable or test.” exit 1 ;; esac command_exists() { command -v “$@” > /dev/null 2>&1 } # version_gte checks if the version specified in $VERSION is at least the given # SemVer (Maj.Minor[.Patch]), or CalVer (YY.MM) version.It returns 0 (success) # if $VERSION is either unset (=latest) or newer or equal than the specified # version, or returns 1 (fail) otherwise. # # examples: # # VERSION=23.0 # version_gte 23.0 // 0 (success) # version_gte 20.10 // 0 (success) # version_gte 19.03 // 0 (success) # version_gte 21.10 // 1 (fail) version_gte() { if [ -z “$VERSION” ]; then return 0 fi eval version_compare “$VERSION” “$1” } # version_compare compares two version strings (either SemVer (Major.Minor.Path), # or CalVer (YY.MM) version strings.
