How to check the version of docker image

You can use the docker images command to view the image version:

The docker images command can list all local image information, where TAG represents the image version information.

Example:

runoob@runoob:~$ docker images

REPOSITORY: Which warehouse it comes from;

TAG: The tag information of the image, such as 5.7 and latest represent different version information;

IMAGE ID: The ID of the image. If you see the two IDs are exactly the same, then in fact, they point to the same image, just with different tag names;

CREATED: The last of the image Update time;

SIZE: Image size, excellent images are generally smaller in size, which is why I prefer to use the lightweight alpine version;
