In this section you will learn how to get information about docker, images, containers, container stats and processes inside a docker container:

For function reference and examples we assume, that we imported systeminformation as follows:

const si = require('systeminformation');

Container, Stats, Processes

All functions in this section return a promise or can be called with a callback function (parameter cb in the function reference)

const si = require('systeminformation');
si.dockerInfo().then(data => console.log(data));
