Questions around environment variables ($JAVA_TOOL_OPTIONS)

Hi Team,

I have a question:

Can anyone give-me a full example of this issue: https://github.com/GoogleContainerTools/jib/issues/1592

I trie to deploy my jib-api on kubernetes, but in my workspace we use JAVA_OPTS on kubernetes deployment, like this:

      - name: JAVA_OPTS
          value: -noverify -XX:TieredStopAtLevel=1 -XshowSettings:vm -XX:MaxRAMPercentage=55
            -XX:InitialRAMPercentage=50 -XX:MinRAMPercentage=30 -XX:+UseContainerSupport

I can’t understand the JAVA_OPTIONS_TOOLS, like FAQ example, or how i configure these variable on POM.

Thanks !

I have to say it is JAVA_TOOL_OPTIONS, not

JAVA_TOOLS_OPTIONS (wrong) JAVA_TOOL_OPTS (wrong) JAVA_TOOLS_OPTS (wrong) JAVA_OPTIONS_TOOLS (wrong)

Most of the JVMs I know will honor JAVA_TOOL_OPTIONS. The Oracle JDK/OpenJDK will print out the message that the environment variable is picked up:

$ JAVA_TOOL_OPTIONS=-Xmx1024m java -Xms256m -Xmx512m -version
Picked up JAVA_TOOL_OPTIONS: -Xmx1024m
openjdk version "1.8.0_212"
...

oh I see: JAVA_TOOL_OPTIONS is automatically picked up by java, you do not have to specify it on the command line. As long as the environment variable is defined, it will incorporate it.
