> How does this allocate on the given LUNS or storage ? By default, it allocates all data in /var/lib/docker. You should start the container pointing it somewhere else, or you will end up filling up /var/lib/docker with the database, and it's not good nor performing. You will probably want to mount a FCP device somewhere on the host and use the --volume parameter to attach it inside the container.
> Can I customise a existing docker image ? Sort of. There are 2 main ways of getting an image: the exported image (like a program binary), and the Dockerfile (like the program source code). The latter is preferred, as you can easily change anything you want, and a Dockerfile is very small (few kb at most). The downside is that not every image will have the Dockerfile available. And most Dockerfiles depend on another Dockerfile, that depends on another Dockerfile... and you got it. To build everything, you must track all Dockerfiles and build each one. But it's doable. Updating the image is easy too: just run docker build again and it creates an updated image. The exported image is larger, multi-GB images are common, and they are more troublesome to customize. You need to deploy the image as a container, change whatever you need, save the container as a new image, and export it if you want to share. Updating it is complicated too: you need to spin up the image on a container, run yum or apt or zypper to update it, and save again. The upside is that you don't need to track dependent Dockerfiles, just export the image and it's done.
