# rabbitmq-kubernetes-worker

## what is it?

a proof of concept application that shows how one can autoscale rabbitmq consumers on kubernetes

## components

### scaler

scales the number of consumers available based on the queue length.

### producer

produces 50 strings of random length strings filled with periods and submits them to a rabbitmq queue ie:

........

.............

.........

......

### consumer

consumes the string sin the queue, timing out for one second for every '.' in the string

### setup

1. copy your `kubeconfig` file to the application directory ie `cp $KUBECONFIG .`

2. `helm install stable/rabbitmq`, follow the instructions to reveal the user and password

3. base64 the user, and password. fill in the appropriate field in `rabbit-secret.yaml`

4. kubectl create -f rabbit-secret.yaml

5. !IMPORTANT¡ create an ACR (or some other private) registry. follow the instructions here to get it configured into your cluster

6. build docker images for each of the components:

    * consumer: `docker build . -t consumermq-k8s -f consumer/Dockerfile`

    * scaler: `docker build . -t scalermq-k8s -f scaler/Dockerfile`

7. tag the images:

    * consumer: `docker tag consumermq-k8s my-private-registry.azurecr.io/consumermq-k8s`

    * scaler: `docker tag scalermq-k8s my-private-registry/azurecr.io/scalermq-k8s`

8. push the images:

    * consumer: `docker push my-private-registry.azurecr.io/consumermq-k8s`

    * scaler: `docker push my-private-registry/azurecr.io/scalermq-k8s`
