Exercises

In this chapter, we have covered a lot of new aspects of the CD pipeline. To help you understand these concepts, we recommend that you complete the following exercises:

1. Add a performance test that tests the hello world service:
   1. The hello world service can be taken from the previous chapter.
   2. Create a performance-test.sh script that makes 100 calls and checks whether the average request-response time is less than 1 second.
