1. Search for mirrors
Use [docker search keyword] to search for shared images. The default search is for images in the official repository.
1. Search the mirror of mysql
The returned information has 5 columns, which represent: image name, image description, number of times it has been favorited, whether it is an official product, and whether it supports automatic creation.
2. Search for mysql mirrors that have been bookmarked more than 2 times
2. Get the mirror
Use [docker pull image name] to download the image from the network.
1. Download the mysql image
Use [docker pull image name] to download the latest tag image of the image set.

3. List local mirrors
Use [docker images] to list images owned on the local host.
The returned information has 5 columns, which represent: image name, image tag, image unique image id, creation time, and size.
Fourth, delete the local mirror
Use [docker rmi image id] to delete the local image, which cannot be deleted when there are still containers using the image.
1. Delete the ubuntu:14.04 image
When we delete the ubuntu:14.04 image, it removes all the AUFS layers that this image came with.
2. Delete the image with the container running
When we try to delete the ubuntu image, we are prompted that there are still containers using the image and cannot be deleted. To delete, you need to stop the container and use the -f parameter to force delete the image.
Five, upload the local mirror
Use [docker push image name] to upload the local image to the official repository.
You can also log in to Docker Hub to see the image just pushed.
6. Create a mirror
