Nexus3, official docker image - how to persistenctly override -XX:MaxDirectMemorySize value?

[Danny Kulchinsky]

Hello,

In the process of deploying Nexus3 using the official docker image, I was able to adjust the Java heap min/max values using the INSTALL4J_ADD_VM_PARAMS env variable, however I don't see a way to persisently control -XX:MaxDirectMemorySize, this value is defined in /opt/sonatype/nexus/bin/nexus.vmoptions and it is not a persistent location (it is part of the docker image).


We have a 32GB server, and according to this we need to adjust this parameter to 17530M, however I don't see a striaghforward way to do it without creating a custom docker image.


Please advise,
Danny

Hi Danny,

This is a good point, our Docker image should allow customization of that value, since we do recommend increasing it on systems that have sufficient RAM to allow it.

I've filed an issue here for this:

Rich
