docker 问题集锦

 

docker-compse 安装报错

docker-compose安装 - 简书 (jianshu.com)

 

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

 

 

vi /etc/resolv.conf

 

nameserver 114.114.114.114

search localdomain

 

添加 国内镜像源

vim /etc/docker/daemon.json

 

{

"registry-mirrors":[

"https://docker.mirrors.ustc.edu.cn",

"https://cr.console.aliyun.com/",

"https://reg-mirror.qiniu.com",

"https://hub-mirror.c.163.com/"

]

}

 

 

systemctl start docker & systemctl daemon-reload

 

出现 守护者进程挂了 就需要先关闭 docker 再启动 systemctl daemon-reload

sudo systemctl stop docker.socket

 

 

 

 

 

Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io: Temporary failure in name resolution

命令

nmtui

 

出现这种情况是我编辑完IP没有设置网关和DNS

设置完毕保存 重启 就能连接外网了

 

 

 

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

 vi /etc/docker/daemon.json 添加 下面镜像源

"https://hub-mirror.c.163.com",
    "https://registry.aliyuncs.com",
    "https://registry.docker-cn.com",
    "https://docker.mirrors.ustc.edu.cn"

　

 

 

b 重新加载docker的配置文件

　sudo systemctl daemon-reload

　c 重启docker

　sudo systemctl restart docker

 

docker开机自启设置   
命令：systemctl enable docker.service   
docker容器的开机自启   

在使用docker run启动容器时，使用--restart参数来设置

例：#  docker run -d --name mysql -p 3306:3306 --restart=always

always - 无论退出状态是如何，都重启容器

 

如果创建时未指定 --restart=always ,可通过update 命令设置

命令：docker update --restart=always 容器ID    
例：docker update --restart=always 9bb3df5a70bf

docker设置开机启动 docker设置容器开机自启
