The calculator service is a small microservice that provides an API to evaluate an mathematical expression. The backend is using math.js to calculate the result.
The service provides an API documentation where the API of the service can tested.
The service is published as a docker image on quay.io under the image name quay.io/kubernetes-workshop/calculator-backend:v1
The service has a major flaw, it will terminate when an invalid expression is passed in as an attribute.
For example the expression Hello World will kill the service.
The service is implemented using Typescript, express.js and node.
You can start the service locally by calling yarn dev.
The service is then running on localhost:8080.
