我正在尝试将图像从一个容器内部推送到同级容器中的注册表，以共享相同的覆盖网络。
我尝试过的例子：
erik@work ~ $ docker run --network mmmmm -it -v /var/run/docker.sock:/var/run/docker.sock ubuntu:latest sh -c "apt-get update ; apt-get install docker.io -y ; bash"
...
root@01574361ba59:/#
root@01574361ba59:/# docker ps -a

root@01574361ba59:/#
root@01574361ba59:/# docker push foobar.xxx.yy:5000/ubuntu
The push refers to a repository [foobar.xxx.yy:5000/ubuntu]
