How to use Java container awareness in OpenShift 4
A brief foray into containerized Java, this article describes the usage and implications of container-aware Java application deployments, and how to use it to your advantage of fully containerized deployments. We also cover the risks of decoupling the heap (off-heap) from the container limits. Finally, we will explain Red Hat OpenShift Container Platform limit settings and specific container-aware troubleshooting tools.
Java is container-aware
When deploying Java inside a container, sometimes we see questions such as:
