工作日记：Dockers安装教程（centOS）
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 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
