Simple application to parse an error log file to aggregate total errors produced by instances of a replicated application as well as total number of errors per replica.

The application is designed with the spcified requirements and some additional assumptions in mind:

• There's multiple applications errors in a log
• We want to target specific application
• We want to target specific instances

Hot reloading is enabled to facilitate rapid testing and tight-feedback during development. Follow the steps below to being developing additional features:

CI/CD

Brings up the containers, executes the integration test and shut down.

make test

Development

Brings up the containers (app & test) for development purposes. The code gets mounted into the contianer and the application hot-reloads to pick up changes -- same applies to the test container.

make dev

API Only

Bring up just the API by running the following command:

make up

Browser Testing

Below are endpoints that you can test via your browser. Note that you may need to change the port if 3000 is already allocated on your machine.

• All application errors
• Application specific errors
• Instance specific errors
• OpenAPI Editor

Shutting down

To kill the running containers, run:

make down

Validating and testing API payload request and responses is done via OpenAPI 3 specification. See api.yaml to better understand the API contract.
