Creating and deploying a Java 8 runtime container image
Orignally posted at Red Hat Developers
A Java runtime environment should be able to run compiled source code, whereas a development kit, for example, OpenJDK, would include all the libraries/binaries to compile and run the source code. Essentially the latter is a superset of the runtime environment. More details on OpenJDK support and lifecycle can be found here.
Red Hat ships and supports container images with OpenJDK for both Java 8 and 11.
