Summary
In this chapter, we learned how to run and debug Node.js, Python, Java, and .NET code running inside a container. We started by mounting the source code from the host into the container to avoid the container image being rebuilt each time the code changes. Then, we smoothed out the development process further by enabling automatic application restarts inside the container upon code changes. Next, we learned how to configure VS Code to enable full interactive code debugging when code is running inside a container.
Finally, we learned how we can instrument our applications so that they generate logging information that can help us do root cause analysis on failures of misbehaving applications or application services running in production. We started by instrumenting our code using a logging library. Then, we used the Open Tracing standard for distributed tracing and the Jaeger tool to instrument a Java and Spring Boot application and gain valuable insight into the application...
