Am deploying springboot application in kubernets using Jib. When the service starting the memory usage is around 300MB but it grows up to 1.3gb over time. How to avoid this increase without any usage? The application is up and running. The API gateways are not open to user now still the memory is incrementing over time.

Do we need to configure anything to limit the memory usage to 1GB limit? Now the kubernets will kill the pod if it goes beyond 1GB.
am creating the image using the Jib.
mvn compile com.google.cloud.tools:jib-maven-plugin:3.3.0:dockerBuild -Dimage=login -DskipTests
