the wildfly-maven-plugin builds a docker image generating a DockerFile on the fly but I need to customize the build to change jboss unix user id (to avoid problems with docker volumes permissions)

The simplest solution consists to pass to <image/> a user defined Dockerfile as shown below
 
<image>
<build>true</build>
<jdk-version>17</jdk-version>
...
<dockerfile>${basedir}/docker/Dockerfile</dockerfile>
...
</image>
 

At this time I build the docker running the docker build command without using maven but should be very useful to use only maven
