Hands-On Microservices with Spring Boot and Spring Cloud

Changes in the test script for use with Kubernetes

To test the deployment we will, as usual, run the test script, that is, test-em-all.bash. To work with Kubernetes, the circuit breaker tests have been slightly modified. Take a look at the testCircuitBreaker() function for more details. The circuit breaker tests call the actuator endpoints on the product-composite service to check their health state and get access to circuit breaker events. The actuator endpoints are not exposed externally, so the test script needs to use different techniques to access the internal endpoints when using Docker Compose and Kubernetes:

• When using Docker Compose, the test script will launch a Docker container using a plain docker run command that calls the ...
