Docker代理配置以及导入导出

代理

关于http代理服务器的搭建,如果有外(国)网机器,直接用squid建就行了 使用Squid3搭建Docker镜像下载代理 。如果已有shadowsocks的代理,可以用privoxy转成http代理服务器。

Edit /etc/sysconfig/docker and add the following lines:
HTTP_PROXY='http://user:password@proxy-host:proxy-port'
HTTPS_PROXY='http://user:password@proxy-host:proxy-port'

For those settings to be taken into account, you’ll need to restart your docker daemon:
# systemctl restart docker

[root@k8s docker.service.d]# pwd
/etc/systemd/system/docker.service.d
[root@k8s docker.service.d]# cat http-proxy.conf 
[Service]
Environment="HTTP_PROXY=http://127.0.0.1:8118/" "NO_PROXY=localhost,127.0.0.1"



查看配置的环境变量是否生效
$ sudo systemctl daemon-reload
$ sudo service docker start
$ sudo systemctl show --property Environment docker

配置代理后下载google容器杠杠的
[root@k8s docker-multinode]# docker pull gcr.io/google_containers/etcd-amd64:3.0.4

如果是自己编译的docker,自启动配置可以参考:https://github.com/docker/docker/blob/master/contrib/init/systemd/docker.socket

导入导出

https://tuhrig.de/difference-between-save-and-export-in-docker/

对于已经通过代理下载的docker,可以通过导入导出到另外的机器。
