002、配置 Docker 镜像加速

 

我的环境为:VMWare + Ubuntu 20.04.1

配置镜像加速的过程:

1、进入文件夹 /etc/docker;   

cd /etc/docker

2、切换到 root 用户( 输入密码 )来进行操作;

sudo su

3、创建daemon.json  (如果存在该文件,无需创建,编辑即可。)

touch daemon.json

4、接下来,如果不会使用 vi 或者 vim 的用户,可能需要先用 exit 退出 root 用户的Bash,然后再用 gedit 打开可视化文本编辑软件:

exit
sudo gedit daemon.json

     这样会在 Ubuntu 系统打开一个类似 Windows 下记事本的对话框。

5、填写镜像地址:
      如果你不知道怎么搞阿里云镜像,你可以在 daemon.json 中填写以下内容:

{
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]
}

科大镜像:https://docker.mirrors.ustc.edu.cn

6、保存并退出。

7、docker hello-world ,检查 镜像加速是否配置成功 ;

root@ubuntu:/etc/docker# docker run hello-world
Unable to find image 'hello-world:latest' locally    # 本地找不到 hello-world
latest: Pulling from library/hello-world    # 从配置的镜像仓库找
2db29710123e: Pull complete     # 拉取完成
Digest: sha256:37a0b92b08d4919615c3ee023f7ddb068d12b8387475d64c622ac30f45c29c51
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.
