How to check which directory the pull image is in docker

1. Enter the docker directory, as follows:

root@iZuf6axmuekh1n14dwcufmZ:/# cd var/lib/docker/ root@iZuf6axmuekh1n14dwcufmZ:/var/lib/docker# ls aufs containers image network plugins swarm tmp trust volumes

2. Enter containers, each serial number is an image , as follows:

cd containers/ 2addde372f5b4850ab167f1067db525313e1569e7117074841cc171acca7621d 4ce1634ce6f17474c8e6696bcf428e621f8c9572e1387316cf8183c97f4ad271

3. Enter one of the mirrors and find that the directory structure is as follows. This is the content of this mirror, as follows:

cd 2addde372f5b4850ab167f1067db525313e1569e7117074841cc171acca7621d/ 2addde372f5b4850ab167f1067db525313e1569e7117074841cc171acca7621d-json.log checkpoints config.v2.json hostconfig.json hostname hosts resolv.conf resolv.conf.hash shm

4. In the directory at the same level as containers, there is a directory called image folder, enter as follows:

cd images/aufs distribution imagedb layerdb repositories.json

There is a repositories.json file inside, which records some information about the image in detail:

(if image If there is no aufs directory, it may be like this

[root@izbp163wlhi02tcaxyu image]# ls overlay2 [root@izbp163wlhi02tcaxyu image]# cd overlay2/ [root@izbp163wlhi02tcaxyu overlay2]# ls distribution imagedb layerdb repositories.json

The command line is as follows:
