docker run报错

1.背景

CentOS安装好docker后，测试时报错

[root@cloud ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Head "https://registry-1.docker.io/v2/library/hello-world/manifests/latest": dial tcp: lookup registry-1.docker.io on 192.168.1.1:53: no such host.
See 'docker run --help'.

2.步骤

# 新建daemon.json文件
sudo vim /etc/docker/daemon.json

# 添加以下内容
{
  "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

# 重启docker
systemctl daemon-reload
sudo systemctl restart docker

仍然报错

[jacob@cloud network-scripts]$ sudo docker pull hello-world
Using default tag: latest
Error response from daemon: Head "https://registry-1.docker.io/v2/library/hello-world/manifests/latest": dial tcp: lookup registry-1.docker.io on 8.8.8.8:53: no such host

# 1、找到可用IP
dig @114.114.114.114 registry-1.docker.io
# 2、找到任一可用ip，添加至hosts文件
vim /etc/hosts
