RabbitMQ

Instructions for setup of rabbitmq on local docker desktop

Configuration

Until requirements make more advanced configurations necessary, the following patterns shall be followed:

• All message producers and consumers shall use the default direct exchange, named 'amq.direct'

• Queues are created and bound to amq.direct by consumer microservices

  • In most cases the default routing is enough. Default routing states that the queue name and routing key are a direct match.

• Producers emit messages with documented routing keys

Running RabbitMQ on Docker Kubernetes

Required

• Docker Desktop with Kubernetes Enabled

• Fork/Clone the current Greenstand Greenstand Infrastructure Repo, the code for the Greenstand RabbitMQ infrastructure is in the RabbitMQ folder

• kubectl

How to run

In the deployment folder the deploy-dev.sh file contains the scripts to set up the RabbitMQ cluster and PodMonitor for the RabbitMQ pods.

Since we're running on local docker-desktop kubernetes cluster, we'll need to change the name cluster name in the deploy-dev.sh.

# kubectl config use-context do-sfo2-dev-k8s-treetracker
kubectl config use-context docker-desktop

Install CRDs

RabbitmqCluster CRD

kubectl apply -f https://github.com/rabbitmq/cluster-operator/releases/latest/download/cluster-operator.yml

PodMonitor CRD

LATEST=$(curl -s https://api.github.com/repos/prometheus-operator/prometheus-operator/releases/latest | jq -cr .tag_name) curl -sL https://github.com/prometheus-operator/prometheus-operator/releases/download/${LATEST}/bundle.yaml | kubectl create -f - 

Create Namespace

For Rabbitmq Greenstand is using the "rabbitmq-cluster" namespace, to create the namespace on your docker kubernetes cluster refer to the docs here.
