Conclusion
To be able to successfully run your software at scale in production, a good understanding of the instrumentation that surrounds the software stack is required. OpenShift is a modern platform that provides all of the capabilities required to observe and, in a lot of cases, automatically heal your applications while they're running.
In this chapter, we have discussed many common technical patterns that allow application developers to make use of these common platform capabilities. For example, one of the simplest patterns is to always log to STDOUT so the platform logging mechanisms can be leveraged. With containers, it becomes an antipattern to log to specific files mounted in a temporary filesystem within your container, because they are not clearly visible.
More complex patterns are also important to keep your business service applications running, even during disruption and change. Correctly configuring liveness, readiness, and startup probes so that your application...
