Docker Compose Reference

Compose File Version 3 Cheat Sheet

Please remember to check your Docker version along with the file version if you run into any
issues. You can find more here:

https://docs.docker.com/compose/compose-file/compose-versioning/

The following commands can be found at ​https://docs.docker.com/compose/reference/

A list of core commands include the following:

Docker-compose up
#​Builds, (re)creates, starts, and attaches to containers for a service.

Docker-compose start
Starts existing containers for a service.

Docker-compose stop
#Stops running containers without removing them. They can be started again with ​docker-compose
start​.

Docker-compose ps
#This command will list containers

#Docker-compose down
#Stops containers and removes containers, networks, volumes, and images created by ​up​.
For a Compose file, we are building a YML or YAML (.yml or .yaml both work) to define our services,
networks, and volumes. The default path for a Compose file is ./docker-compose.yml.

Version 3 Example

For examples of version 3 please see:
