Frame conditions

1. You have exact 2.5 hours of time - no minute longer.

   If you reach this time limit stop your work immediately. It is one part of the kata to respect this time limit. 🙂

2. There are no restrictions on how to use the provided time. If you want to code the entire time, take a break or a cigarette; it’s up to you.

3. This is a real world situation. You are allowed to consult the Internet, use every library you want, call a friend ...

4. It is fully up to you how you operate this one. If you choose an AWS EC2 instance, a Kubernetes cluster, your local machine, ...; you choose download the binary directly, build your own docker build pipeline, ...; everything could make sense.

5. Keep the following priorities in mind while you implementing - in the mentioned order:

   1. Reliability
   2. Maintainability
   3. Functionality

6. The service which should be operated itself can be found in pkg/service.

   1. It is fully functioning as it is.

   2. By default, it is listening to 127.0.0.1:8000. It can be overwritten using the environment variable KATA_SERVICE_ADDRESS.

   3. It is serving the following endpoints:

      • / a regular endpoint which prints out a simple response text.
      • /crash an endpoint which will let the service crash immediately.

   4. It is written in Go.

   5. It can be retrieved...

      • ...either as the latest binary retrieved directly from our pre-packaged releases
      • ...or building it yourself using (if at Go 1.19+ is installed):

        # Linux/macOS
        $ go build -o service ./pkg/service
        # Windows
        $ go build -o sevice.exe ./pkg/service

Acceptance criteria

1. The service is handling the endpoint / continuously.
2. The service is handling the endpoint /crash continuously.
