As toISOString() will only return current UTC time , not local time. We have to make a date by using .toString() function to get date in yyyy-MM-dd format like

let now = new Date(new Date().toString().split('GMT')[0]+' UTC').toISOString().split('T')[0];
// 2019-10-04

To get date and time into in yyyy-MM-ddTHH:mm:ss format

ports

Activates the container to listen for specified port(s) from the world outside of the docker(can be same host machine or a different machine) AND also accessible world inside docker.
More than one port can be specified (that's is why ports not port)

expose

Activates container to listen for a specific port only from the world inside of docker AND not accessible world outside of the docker.
