eclipse-temurin:17-jdk-* VS eclipse-temurin:17-jre-*

[chibenwa]

Hello there.

I see eclipse-temurin:17-jdk-* on docker hub and no eclipse-temurin:17-jre-*.

Is there any reason? Any plan to support those in the future?

But it looks like they follow the same support matrix as us docker-library/openjdk#272

Essentially upstream only publishes the JDK
docker-library/openjdk#302 (comment)

Upstream does not distribute an official JRE package that I am aware of, nor do they have documentation for either what bits from the official downloads should be kept or what bits should be removed to create an official JRE package, so this will not involve that. (Folks wishing to create a JRE based on OpenJDK 12+ are likely better off playing with jlink anyhow to create their own custom minimal JRE via a multi-stage build or similar -- I've personally done so via the existing Oracle Linux image with a multi-stage build copying the resulting minimal JRE into a Debian-based image with great success.)
