docker –version Docker version 18.09.0
1.进入docker 目录
root@Rightsec:~# cd /var/lib/docker root@Rightsec:/var/lib/docker# ls builder buildkit containers image network overlay2 plugins runtimes swarm tmp trust volumes
2.进入containers,每个序列号都是一个image
root@Rightsec:/var/lib/docker# cd containers/ root@Rightsec:/var/lib/docker/containers# ls e36d800f663b626aef2c625c48c353555d9b203e13e7e49093d15be2f3a0fb6e
3.进入镜像可以看到
root@Rightsec:/var/lib/docker/containers# cd e36d800f663b626aef2c625c48c353555d9b203e13e7e49093d15be2f3a0fb6e/ root@Rightsec:/var/lib/docker/containers/e36d800f663b626aef2c625c48c353555d9b203e13e7e49093d15be2f3a0fb6e# ls checkpoints hostconfig.json mounts config.v2.json hostname resolv.conf e36d800f663b626aef2c625c48c353555d9b203e13e7e49093d15be2f3a0fb6e-json.log hosts resolv.conf.hash
4.进入image文件夹，里面有repositories.json的文件，详细记录了各镜像的一些信息:
root@Rightsec:/var/lib/docker# cd image/ root@Rightsec:/var/lib/docker/image# ls overlay2 root@Rightsec:/var/lib/docker/image# cd overlay2/ root@Rightsec:/var/lib/docker/image/overlay2# ls distribution imagedb layerdb repositories.json
