Introduction

This module allows one to deal with docker-compose file in a directory.

This is a first version only, the following commands are missing at the moment but will be built later on if the community is interested in this module:

• run
• logs
• port
• scale

Installation Prerequisites

This execution module requires at least version 1.4.0 of both docker-compose and Docker. docker-compose can easily be installed using pip.install:

salt myminion pip.install docker-compose>=1.5.0

How to use this module?

In order to use the module if you have no docker-compose file on the server you can issue the command create, it takes two arguments the path where the docker-compose.yml will be stored and the content of this latter:

# salt-call -l debug dockercompose.create /tmp/toto '
database:
image: mongo:3.0
command: mongod --smallfiles --quiet --logpath=/dev/null
'

Then you can execute a list of method defined at the bottom with at least one argument (the path where the docker-compose.yml will be read) and an optional python list which corresponds to the services names:

# salt-call -l debug dockercompose.up /tmp/toto
# salt-call -l debug dockercompose.restart /tmp/toto '[database]'
# salt-call -l debug dockercompose.stop /tmp/toto
# salt-call -l debug dockercompose.rm /tmp/toto

Detailed Function Documentation
