mount

• when you have some codes that don't want to upload to docker registry.
• Suffix your command with -v <full path>.

docker compose

• Incase you have to type a long command like docker run -d -p 7200:3000 -v /Users/xxxxx/Documents/ddddd/workingfolder:/hello trust/helloworld
• You can replace that command with an .yml file.
• docker-compose.yml

version: '3.1'

services: 
    helloworld:
        image: trust/helloworld
        ports:
         - 7200:3000
        container_name: helloworld
        volumes:
         - /Users/xxxxx/Documents/ddddd/workingfolder:/hello
    

• and run with docker-compose up -d within the directory that .yml exists.
