Installation

[root@localhost /] # yum-y install docker-io

Start the docker service

[root@localhost /] # service docker start

Starting cgconfig service: [OK]

Starting docker: [OK]

Add docker to boot boot

Basic information view

Docker version: check the version number of docker, including client, server, dependent Go, etc.

Docker info: view system (docker) level information, including managed images, number of containers, etc.

Directory where docker files are stored

Docker puts everything under the / var/lib/docker path.

[root@localhost docker] # ls-F

Containers/ devicemapper/ execdriver/ graph/ init/ linkgraph.db repositories-devicemapper volumes/

Of course, the containers directory is the storage container (container), the graph directory stores the image, and the file layer (file system layer) is stored under the graph/imageid/layer path. You can view the file layer. You can use this hierarchical structure to see how the file layers are superimposed layer by layer.

View root password

The password of the root user when the docker container starts is randomly assigned. View command

Docker logs 5817938c3f6e 2 > & 1 | grep 'User:' | tail-N1
