待我称王封你为后i 2023-07-20 05:45 35阅读 0赞

我的ubuntu 版本是 18.04.1   ，刚才安装 好的，干净的系统，如有同学之前安装过，必须卸载后，才能重新安装

具体安装步骤如下

# 一、设置仓库 #

为了设置仓库，需要有几个前置步骤，完成之后才是真正设置仓库，具体如下

##   1、更新 apt 包索引。 ##

sudo apt-get update

执行结果如下

## 2、安装 apt 依赖包，用于通过HTTPS来获取仓库: ##

sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

执行结果如下

##  3、添加 Docker 的官方 GPG 密钥：   ##

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

执行结果如下

结果为ok，表示成功了

9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 这个官方密钥，可验证刚才设置的结果

具体如下

sudo apt-key fingerprint 0EBFCD88      （注： sudo apt-key fingerprint 后面是官方密钥后面的8位）

执行结果如下

这个表示验证成功

## 4、设置稳定版仓库 ##

sudo add-apt-repository "deb \[arch=amd64\] https://download.docker.com/linux/ubuntu $(lsb\_release -cs) stable"

执行结果如下

# 二、安装 Docker Engine-Community #

##    1、更新 apt 包索引 ##

sudo apt-get update

执行结果如下

##   2、安装最新版本的 Docker Engine-Community 和 containerd ，或者转到下一步安装特定版本： ##

sudo apt-get install docker-ce docker-ce-cli containerd.io

执行结果如下

# 3、列出可用版本（注：这里安装特定版本，所以安装前需要列出可用版本） #

apt-cache madison docker-ce

执行结果如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3liNTQ2ODIyNjEy_size_16_color_FFFFFF_t_70 1][]

## 4、安装 ##

这里选择 5:19.03.8~3-0~ubuntu-bionic 列表中第一个版本，这只是个人建议，这个版本不是最新也不是最旧，其实使用起来差距不大，

sudo apt-get install docker-ce=5:18.09.0~3-0~ubuntu-bionic docker-ce-cli=5:18.09.0~3-0~ubuntu-bionic containerd.io

执行结果如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3liNTQ2ODIyNjEy_size_16_color_FFFFFF_t_70 2][]

## 5、测试是否成功 ##

sudo docker run hello-world

执行结果如下，说明安装成功了
