Build stackgres images are fairly simple. You can build in two forms:
Compiles fast but has a higher memory footprint. So it useful for local environment testing
Go to the stackgres/stackgres-k8s/src folder and the execute:
./mvnw clean verify -P build-image-jvm
You can find the image in th stackgres/operator repository tagged as development-jvm
Takes long to compile but has a lower memory footprint. Is recommended for production workloads.
The native image use GraalVM but at the expense of some limitations. So once your development is ready, be sure to test it with the native image.
To generate a native image simpleme run:
./mvnw clean verify -P native,build-image-native
