Dockers安装教程

一、正常安装

1、卸载旧版本

yum remove docker 
           docker-client 
           docker-client-latest 
           docker-common 
           docker-latest 
           docker-latest-logrotate 
           docker-logrotate 
           docker-engine

2、需要的安装包

yum install -y yum-utils

3、设置镜像的仓库

默认是从国外的！（不推荐）

yum-config-manager 
	--add-repo 
	https://download.docker.com/linux/centos/docker-ce.repo

使用阿里源（推荐）

yum-config-manager 
	--add-repo 
	http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

更新yum软件包索引

yum makecache fast

4、安装docker依赖

docker-ce：社区版
docker-ee：企业版

yum install docker-ce docker-ce-cli containerd.io

5.修改配置文件

路径： /etc/docker/daemon.json
没有daemon.json文件则新建

{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "features": {
    "buildkit": true
  },
  "live-restore": true,
  "registry-mirrors": [
    "https://docker.211678.top",
    "https://docker.1panel.live",
    "https://hub.rat.dev",
    "https://docker.m.daocloud.io",
    "https://do.nark.eu.org",
    "https://dockerpull.com",
    "https://dockerproxy.cn",
    "https://docker.awsl9527.cn/"
  ],
  "data-root":"/mnt/sdb/dockerdata"
}

注：“data-root”:“/mnt/sdb/dockerdata” 是镜像保存位置，可修改

6、启动docker

systemctl start docker

测试是否启动成功

docker version

7、拉取镜像

docker run hello-world

8、查看镜像

docker images

9、卸载docker

卸载docker依赖

yum remove docker-ce docker-ce-cli containerd.io

删除资源

rm -rf /var/lib/docker

二、脚本安装

新建一个sh文件，命名为get-docker.sh

#!/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 
# 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
#
# ==============================================================================


# Git commit from https://github.com/docker/docker-install when
# the script was uploaded (Should only be modified by upload job):

上传到服务器中
在此路径下执行

sudo sh get-docker.sh --mirror Aliyun

等到安装完成即可

修改配置文件

路径： /etc/docker/daemon.json
没有daemon.json文件则新建

{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "features": {
    "buildkit": true
  },
  "live-restore": true,
  "registry-mirrors": [
    "https://docker.211678.top",
    "https://docker.1panel.live",
    "https://hub.rat.dev",
    "https://docker.m.daocloud.io",
    "https://do.nark.eu.org",

    "https://dockerproxy.cn",
    "https://docker.awsl9527.cn/"
  ],
  "data-root":"/mnt/sdb/dockerdata"
}

注：“data-root”:“/mnt/sdb/dockerdata” 是镜像保存位置，可修改
