Where is OpenJDK 12 JRE version image?

[XhstormR]

OpenJDK 12 image on Docker Hub only has JDK version, is there a plan for the JRE version?

Our builds for OpenJDK 12 come from https://jdk.java.net/12/, and as you can see they're JDK only. I don't believe they publish an associated JRE artifact, nor am I aware of any official documentation on what to do with that JDK artifact to turn it into a generic JRE.

What I would recommend though, is that you use a multi-stage build and the jlink utility to create for yourself a minimal JRE that only includes the specific standard library classes your application requires (so that you essentially end up creating your own hyper-optimized JRE image). 👍

For further assistance, I'd recommend trying the Docker Community Forums, the Docker Community Slack, or Stack Overflow.
