The Docker client contacted the Docker daemon.2. The Docker daemon pulled the hello-world image fromthe Docker Hub.(amd64)3. The Docker daemon created a new container fromthat image which runs theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.Totrysomething more ambitious, you can run an Ubuntu container with:$ docker run-it ubuntu bashShare images, automate workflows, and more with a free Docker ID:https://hub.docker.com/For more examples and ideas, visit:https://docs.docker.com/get-started/5、重新登录docker hubdocker login -u xxx -p xxxlogin Suceeded可以看到已经成功解决问题参考自官方文档https://docs.docker.com/engine/admin/systemd/
