-## 开始部署
-
-1. 卸载就办 Docker
-
-   ```bash
-   sudo yum remove docker \
-       docker-client \
-       docker-client-latest \
-       docker-common \
-       docker-latest \
-       docker-latest-logrotate \
-       docker-logrotate \
-       docker-engine
-   ```
-
-2. 设置存储库
-
-   ```bash
-   yum install -y yum-utils
-   ```
-
-   ```bash
-   yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
-   ```
-
-   > 国内源
-   >
-   > ```bash
-   > yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
-   > ```
-
-3. 安装最新版
-
-   ```bash
-   yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
-   ```
-
-   > 安装特定版本
-   >
-   > - 查看版本库
-   >
-   >   ```bash
-   >   yum list docker-ce --showduplicates | sort -r
-   >   ```
-   >
-   > - 安装
-   >
-   >   ```bash
-   >   sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io docker-buildx-plugin docker-compose-plugin
-   >   ```
-
-4. 启动
-
-   ```bash
-   systemctl enable docker
-   systemctl start docker
-   ```

+# 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+#   to the expected version, resulting in outdated versions.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
+#
+# --setup-repo
+#
+# Use the --setup-repo option to configure Docker's package repositories without
+# installing Docker packages. This is useful when you want to add the repository
+# but install packages separately:
+#
+#   $ sudo sh install-docker.sh --setup-repo
+#
+# ==============================================================================

+
+# Git commit from https://github.com/docker/docker-install when
