Prerequisites

Docker must be installed
Docker-Compose must be installed

Installation

Download docker-compose-wrapper script to /usr/local/bin folder:

sudo wget https://raw.githubusercontent.com/chrisipa/docker-compose-wrapper/master/docker-compose-wrapper -O /usr/local/bin/docker-compose-wrapper

Make docker-compose-wrapper script executable:

sudo chmod +x /usr/local/bin/docker-compose-wrapper

Create sample init script /etc/init.d/my-app-stack for your application stack:

#!/bin/bash
### BEGIN INIT INFO
# Provides:          my-app-stack
# Required-Start:    docker
# Required-Stop:
# Default-Start:     3 5
# Default-Stop:      0 1 2 6
# Description:       My App Stack Init Script
### END INIT INFO

# set environment variables
export TZ="Europe/Berlin"

# set compose file location
composeFile="/opt/my-app-stack/docker-compose.yml"

# include docker-compose-wrapper script
source /usr/local/bin/docker-compose-wrapper

Make init script executable:
```
sudo chmod +x /etc/init.d/my-app-stack
```
Register init script for autostart:
```
sudo chkconfig my-app-stack on
```
Now you can use your init script to control docker-compose in a convenient way:
```
sudo service my-app-stack
```
