Docker its a stack of products there using OS-level virtualization to delivery software we called containers. Every single docker container is isolated from others docker containers.
Docker is open source and free to install and use, the software you installed on your host called Docker Engine, You can get data from Docker Engine based on Docker Socket there allow you to use the Docker Engine API to get data from the Docker Engine host.
