Linux 主流发行版 Docker 安装


1. 卸载旧版 Docker

1.1 CentOS 卸载

$ sudo yum remove docker \  
              docker-client \  
              docker-client-latest \  
              docker-common \  
              docker-latest \  
              docker-latest-logrotate \  
              docker-logrotate \  
              docker-engine

1.2 Ubuntu 以及 Debian 卸载

$ sudo apt-get remove docker docker-engine docker.io containerd runc

2. 安装 Docker 软件仓库

在新主机上首次安装 Docker Engine-Community 之前,需要设置 Docker 仓库。之后,您可以从仓库安装和更新 Docker。

2.1 CentOS 安装软件源

设置软件源

安装所需的软件包。yum-utils 提供了 yum-config-manager ,并且 device mapper 存储驱动程序需要 device-mapper-persistent-data 和 lvm2。

$ sudo yum install -y yum-utils \  
 	      device-mapper-persistent-data \  
 	       lvm2

使用以下命令来设置稳定的软件源。

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

2.2 Ubuntu 以及 Debian 安装软件源

设置软件源

更新 apt 包索引。

$ sudo apt-get update

安装 apt 依赖包,用于通过 HTTPS 来获取软件源:

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

添加 Docker 的官方 GPG 密钥:

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

9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 通过搜索指纹的后 8 个字符,验证您现在 >> 是否拥有带有指纹的密钥。

$ sudo apt-key fingerprint 0EBFCD88     

pub   rsa4096 2017-02-22 [SCEA]  
     9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88  
uid           [ unknown] Docker Release (CE deb) <docker@docker.com>  
sub   rsa4096 2017-02-22 [S]  

使用以下指令设置稳定版软件源

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

更新 apt 包索引。

$ sudo apt-get update

3. 安装 Docker Engine-Community

安装最新版本的 Docker Engine-Community 和 containerd

3.1 CentOS 安装

$ sudo yum install docker-ce docker-ce-cli containerd.io
  • 如果提示您接受 GPG 密钥,请选是。

3.2 Ubuntu 以及 Debian 安装

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

4. 验证安装成果

启动 Docker。

$ sudo systemctl start docker

测试 Docker 是否安装成功,输入以下指令,打印出以下信息则安装成功:

$ sudo docker run hello-world  

Unable to find image 'hello-world:latest' locally  
latest: Pulling from library/hello-world  
1b930d010525: Pull complete                                                                                                                                 Digest: sha256:c3b4ada4687bbaa170745b3e4dd8ac3f194ca95b2d0518b417fb47e5879d9b5f  
Status: Downloaded newer image for hello-world:latest  
 
 
Hello from Docker!  
This message shows that your installation appears to be working correctly.  
 
 
To generate this message, Docker took the following steps:  
1. The Docker client contacted the Docker daemon.  
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.  
  (amd64)  
3. The Docker daemon created a new container from that image which runs the  
   executable that produces the output you are currently reading.  
4. The Docker daemon streamed that output to the Docker client, which sent it  
   to your terminal.  
 
 
To try something more ambitious, you can run an Ubuntu container with:  

开机启动

$ sudo systemctl enable docker

禁用开机启动

$ sudo systemctl disable docker
