What is the process to set memory limit for Java 11 inside Docker?
Which JDK to use for production environment?

- As java 11 (10+) can automatically detect the container's memory you can set memory limit on your container and it should WAI:
docker run -m 512 ....
- As for the choice of JDK, you can either use oracle JDK which is licensed or open source OpenJDK.
More details in this article: https://www.docker.com/blog/improved-docker-container-integration-with-java-10/
You can set the maximum heap size using the hotspot JVM -Xmx option (see java 11 options)
You may use AdoptOpenJDK for production as they are kept up tp date.
