When using root@book:~# docker pull mysql
Download and download the MySQL image in the virtual machine The download speed is impressive, not to mention time-consuming, and I don’t know when it will stop moving, and the installation can’t be completed
Use the domestic mirror daocloud.io/library library to download
input command
docker pull daocloud.io/library/centos:latest
After completion, as shown in the figure, and then download the MySQL image, enter
docker pull daocloud.io/library/mysql:5.7
really fast
