Crovel

Crovel is not Shovel but does almost the same, namely to forward messages from one RabbitMQ exchange to another. Only, it does this with a crovel instead of a shovel.

Usage

Set the following environment variables to wire things up

Environment	Description	Required	Default
CROVEL_SRC_EXCHANGE	Name of source exchange	yes
CROVEL_SRC_ROUTING_KEY	Source routing key	no	#
CROVEL_SRC_EXCHANGE_TYPE	Source exchange type	no	topic
CROVEL_DEST_EXCHANGE	Destination exchange	yes
CROVEL_DEST_EXCHANGE_TYPE	Destination exchange type	no	topic

Deploy

Deploy to Cloud Foundry and bind the RabbitMQ service to the app

Example manifest

---
applications:
- name: crovel
  docker:
    image: loafoe/crovel:latest
  instances: 1
  memory: 32M
  disk_quota: 128M
  health-check-type: process
  env:
    CROVEL_SRC_EXCHANGE: foo
    CROVEL_DEST_EXCHANGE: bar
  services:
  - rabbitmq

Example Terraform

resource "cloudfoundry_app" "crovel" {
  name         = "crovel"
  space        = data.cloudfoundry_space.space.id
  memory       = 32
  disk_quota   = 128
  docker_image = "loafoe/crovel:latest"
  health_check_type = "process"
  environment = {
    CROVEL_SRC_EXCHANGE  = "foo"
    CROVEL_DEST_EXCHANGE = "bar"
  }
  service_binding {
    service_instance = cloudfoundry_service_instance.rabbitmq.id
  }
}

Ideas

• Support forwarding to different RabbitMQ cluster
• Support mulitple exchange forwards per instance
• Configurable durability
