@Mojo(name="docker-crac",
      requiresDependencyResolution=COMPILE_PLUS_RUNTIME)
public class DockerCracMojo
extends AbstractDockerMojo

Implementation of the docker-crac packaging.

WARNING: this goal is not intended to be executed directly. Instead, specify the packaging type using the packaging property, eg:

mvn package -Dpackaging=docker-crac

This is a two stage process. First a docker image is built that runs the application under a CRaC enabled JDK. Then the application is warmed up via a shell script. And then a checkpoint is taken via a signal using jcmd.

The second stage takes this checkpoint, and creates the final image containing it plus a run script which passes the correct flags to the CRaC enabled JDK.

Since:

3.5.0
