Skaronator opened a new issue #7859: URL: https://github.com/apache/pulsar/issues/7859
**Is your enhancement request related to a problem? Please describe.** The current docker images are built with Java 8. According to the [2.3.0 - 2019-02-20](https://pulsar.apache.org/release-notes/#230-mdash-2019-02-20-a-id230a) changelog Pulsar supports Java 11 since version Java 8 and Docker doesn't work that well together. Some things got backported to Java 8 but only Java 10+ supports Memory and CPU limits inside Docker Containers correctly. More on that here: https://www.royvanrijn.com/blog/2018/05/java-and-docker-memory-limits/ **Describe the solution you'd like** I'd like to see Docker Images that use Java 11 & use the correct start parameters by default. The current images rely on openjdk:8 https://github.com/apache/pulsar/blob/b410274554508684f4a15cc1f5a98a71d85fbe2e/docker/pulsar/Dockerfile#L41 https://github.com/apache/pulsar/blob/b410274554508684f4a15cc1f5a98a71d85fbe2e/docker/pulsar-standalone/Dockerfile#L27 **Describe alternatives you've considered** Alternatively there could be a java11 version of the image, parallel to the current images. Like "2.7.0" and "2.7.0-java11" https://hub.docker.com/r/apachepulsar/pulsar/tags ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
