Tanks for response. But my questions is : >From the tomee image https://docs.docker.com/samples/library/tomee/
Inside the docker file i see that the tomee binaries are downloaded. So into the tomee/conf dir is already present a tomee.xml when from the image the tomee is downloaded. So i ask: how i can ads the configuration of darasource into the tomee.xml? I can pit a new tomee.xml using option -v of docker volume . But in this case i have to erase the already preaent tomee.xml downloaded into the image ? I hope i explained my problem.
