 .Filtering
 {plugin} filters given Dockerfile with Maven properties, much like the `maven-resource-plugin` does. Filtering is enabled by default and can be switched off with a build config `<filter>false</filter>`. Properties which we want to replace are specified with the `${..}` syntax.
-Replacement includes Maven project properties such as `${project.artifactId}`, properties set in the build, command-line properties, and system properties. Unresolved properties remain untouched.

 This partial replacement means that you can easily mix it with Docker build arguments and environment variable reference, but you need to be careful.
 If you want to be more explicit about the property delimiter to clearly separate Docker properties and Maven properties you can redefine the delimiter.
