# Overview
|
|
|
|
**Docker** is a container technology that uses the hosts kernel while putting the userland applications into a sandbox.
|
|
It is much more lightweight than a full-fledged virtual machine, but can only run stuff that can run on host.
|
|
|
|
**Compose** is a Docker tool that allows defining containers using a YAML file and run them with a single command.
|
|
|
|
The purpose of docker and docker-compose is either development or deployment.<br>
|
|
Most of the stuff around here is about deployment, how to deploy others people work<br>

# Basics
|
|
|
|
tag - not just version number, tags are not even present on local docker..
|
|
|
|
ports quotes - always in quotes because in low number it might try to interpret ports as base 60
