拉取镜像报错信息如下：

ERROR: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

很多docker镜像源用不了，这些是我全网搜集的最新可用的镜像源，按照步骤配置就能正常使用了

修改Docker配置文件

vi /etc/docker/daemon.json

添加以下内容

{
"registry-mirrors"
: [
"https://docker.m.daocloud.io"
,
"https://noohub.ru"
,
"https://huecker.io"
,
"https://dockerhub.timeweb.cloud"
,
"https://0c105db5188026850f80c001def654a0.mirror.swr.myhuaweicloud.com"
,
"https://5tqw56kt.mirror.aliyuncs.com"
,
"https://docker.1panel.live"
,
"http://mirrors.ustc.edu.cn/"
,
"http://mirror.azure.cn/"
,
"https://hub.rat.dev/"
,
"https://docker.ckyl.me/"
,
"https://docker.chenby.cn"
,
"https://docker.hpcloud.cloud"
,
"https://docker.m.daocloud.io"
]
}

使之生效

systemctl daemon-reload

重启

systemctl restart docker

或者直接使用以下这个

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": [
    "https://2a6bf1988cb6428c877f723ec7530dbc.mirror.swr.myhuaweicloud.com",
    "https://docker.m.daocloud.io",
    "https://hub-mirror.c.163.com",
    "https://mirror.baidubce.com",
    "https://your_preferred_mirror",
    "https://dockerhub.icu",
    "https://docker.registry.cyou",
    "https://docker-cf.registry.cyou",
    "https://dockercf.jsdelivr.fyi",
    "https://docker.jsdelivr.fyi",
    "https://dockertest.jsdelivr.fyi",
    "https://mirror.aliyuncs.com",
    "https://dockerproxy.com",
    "https://mirror.baidubce.com",

    "https://docker.mirrors.ustc.edu.cn",
    "https://mirror.iscas.ac.cn",
    "https://docker.rainbond.cc"
  ]
}

EOF
