Docker build does not copy keystores into container

Scenario:

You've configured your own docker image with a custom keystore. This keystore is now available in the environment files. However, during the docker build stages, the file is not copied into the container and the build fails. What could be wrong here?

Solution:

The keystore copying may be skipped when you have appServerType=skipAppServerCheck in the WAR file installer inside the downloaded distro for docker build. This needs to be set back to appServerType=tomcat after the keystore generation.
