Since Azul Zulu Prime JVM 19.07 Zing does not need the ZST component anymore which was required in earlier versions. To run Azul Zulu Prime JVM within a Container now you only need to extract the Azul Zulu Prime JVM tar.gz package inside the container. The Azul Zulu Prime JVM tar.gz is available on Azul Platform Prime downloads.
For setting the Java heap size on containers, see Heapsize Settings.
Alternatively, you can also install Azul Platform Prime from a package repository inside a container as explained on the following page which shows a Dockerfile example: Get Started with Azul Platform Prime in a Docker Container
