Docker with Puppet Scaling a docker service

Question

I have a docker service named as "redis" there's a need to scale this service amounting to have atleast 10 of them. How can i use puppet to do container scaling? 

Answer 1

To scale a service, add the following code to the puppet manifest file:

docker::services {'redis_scale':
  create => false,
  scale => true,
  service_name => 'redis',
  replicas => '10',
}

To scale the service without creating a new one, include the the scale => true parameter and the create => false parameter.

In the code snippet given above, the service is scaled to 10.
