Project structure

• env Folder containing the PostgreSQL env variables for the docker-compose deployment

• helm-config Helm chart values for PostgreSQL and ingress-nginx

• k8s Folder containing the kubernetes deployments, apps and services for the ingress, order, payment and stock services.

• order Folder containing the order application logic and dockerfile.

• payment Folder containing the payment application logic and dockerfile.

• stock Folder containing the stock application logic and dockerfile.

• test Folder containing some basic correctness tests for the entire system.

Port assignments

• order:5000
• payment:6000
• stock:7000

Deployment types:

docker-compose (local development)

Run docker-compose up --build in the base folder.

Requirements: You need to have docker and docker-compose installed on your machine.

minikube (local k8s cluster)

This setup is for local k8s testing to see if your k8s config works before deploying to the cloud.

To deploy the app on a minikube cluster run ./setup-minikube.sh (and minikube dashboard for monitoring). In case of an "insufficient cpu" error, pods 1-3 from k8s/order-app.yaml, k8s/payment-app.yaml and k8s/stock-app.yaml can be safely commented out.

The images of each service are also on dockerhub:

• bobdetest123/orderserivce:order
• bobdetest123/orderserivce:payment
• bobdetest123/orderserivce:stock

Requirements: You need to have minikube (with ingress enabled) and helm installed on your machine.

kubernetes cluster (managed k8s cluster in the cloud)

Similarly to the minikube deployment but run the deploy-charts-cluster.sh in the helm step to also install an ingress to the cluster.

Requirements: You need to have access to kubectl of a k8s cluster.
