How to check which directory the pull image is in docker

Method: 1. Use the "cd var/lib/docker/" command to enter the docker directory; 2. Use the "cd containers/" command to enter containers. Each serial number is an image; 3. Use the cd command Just enter one of the mirrors to view the directory structure.

The operating environment of this tutorial: linux7.3 system, docker-1.13.1 version, Dell G3 computer.

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/

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:
