Check details of image, container, node, service configuration in Docker

Docker inspect is used to low level information on docker object like container, image, volume, network, task, node, service etc.

It will provide the detail of information like Ip address, name or anything specific in detail needed before start the image: I am checking information of image by providing image name:

Command: docker inspect image-name/servicename/containername/

root@Oracle1:/home/sunny/Desktop# docker inspect image-oracle
