How to install and enable a service in amazon Elastic Beanstalk?

Question

I'm banging my head against a wall trying to both install and then enable a service in elastic beanstalk. What I want to do is:

1. Install a service in /etc/init.d that points to my python app in /opt/python/current/app/

2. Have Elastic Beanstalk start and keep-alive the service, as specified in an .ebextensions/myapp.config file.

(Reference: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-ec2.html#customize-containers-format-services)

Here's my .ebextensions/myapp.config file:

container_commands:
  01_copy_service:
    command: "cp /opt/python/ondeck/app/my_service /etc/init.d/"
  02_chmod_service:
    command: "chmod +x /etc/init.d/my_service"

services:
  sysvinit:
    my_service:
      enabled: true
      ensureRunning: true
      files : [/etc/init.d/my_service]

This fails because services are run before container_commands. If I comment out services, deploy, then uncomment services, then deploy again, it will work. But I want to have a single-step deploy, because this will be an auto-scaling node.

Is there a solution? Thanks!

Nate, I have the exact same scenario as you and I solved it this way:

Drop the "services" section and add a "restart" command.

container_commands:
  ...
  03_restart_service:
    command: /sbin/service my_service restart

You can cause the service to restart after a command is run by using a commands: key under the services: key. The documentation for the services: key is here:
