K8S microservices template

Architecture Diagram

Enable K8S for local development using Docker Desktop

Settings -> Kubernetes -> Enable Kubernetes -> Apply & Restart

Make sure to switch to the right context.

kubectl config get-contexts
kubectl config use-context docker-desktop

MongoDB Atlas Operator

chmod +x ./k8s/atlas/atlas-operator.sh
./k8s/atlas/atlas-operator.sh --org_id <org_id> --atlas_public_key <atlas_public_key> --atlas_private_key  <atlas_private_key> --mongo_pw <mongo_pw>

MongoDB connection string

Wait until the cluster spun up and run below command. kubectl get secret k8s-micro-cluster0-mongok8s -o json | jq -r '.data | with_entries(.value |= @base64d)'

RabbitMQ Cluster Operator

chmod +x ./k8s/rabbitmq/rabbitmq-operator.sh
./k8s/rabbitmq/rabbitmq-operator.sh --aws_access_key_id <aws_access_key_id> --aws_secret_access_key <aws_secret_access_key> --from_email <from_email>

username="$(kubectl get secret rabbitmq-cluster-default-user -o jsonpath='{.data.username}' | base64 --decode)"
password="$(kubectl get secret rabbitmq-cluster-default-user -o jsonpath='{.data.password}' | base64 --decode)"
echo "username: $username"
echo "password: $password"

Kill any process that listen on port 80

lsof -i :80
kill -9 <pid>

K8S resources

kubectl apply -f ./k8s
kubectl apply -f ./k8s/ingress/ingress-docker-desktop.yml
kubectl apply -f ./k8s/ingress/ingress-service.yml

Create the product in MongoDB

curl --location 'http://localhost/api/products' \
--header 'Content-Type: application/json' \
--data '{
    "name": "Hoodie",
    "description": "Nice to wear",
    "price": 20,
