Hi, is there a way to: a) access the Alpine VM that comes with Docker for Mac (“Moby”) b) switch the used image? e.g. where can I find the sources for “Moby”? (GPL?) I’ll need a specific kernel module loaded in the (host) kernel. ---

Hi we plan to fully open source the Linux distro soon. We can of course provide all sources, any kernel patches will be in the distro in `/etc/`. The current beta is vanilla 4.4.6+aufs, you can get the kernel config with: `docker run --privileged --pid=host alpine zcat /proc/1/root/proc/config.gz` You can in theory replace the kernel image in the application bundle with a new one, but we won’t be able to help with bugs - we are trying to fix the issues with a vanilla setup… We can add more mainstream config options if they are generally appropriate - what do you need? ---

> [@justincormack](#): > > We can add more mainstream config options if they are generally appropriate - what do you need? Thanks for your help! Unfortunately it’s not a mainstream option and requires custom patching + custom userspace daemon. Currently we have a modified “boot2docker”-distro image and use VMWare Fusion with docker-machine but are very unhappy with the recent development of Fusion. So xhyve-based Docker for Mac looks very compelling. ---

We are not going to help with this type of request at present as we want to get the mainstream features working, but you should be able to run a daemon via a privileged container fairly easily, and you can change the kernel, or add modules, but you will have to work it out on your own. ---

As long as I know what I need to build, I can do it myself. That’s why I asked for the sources 😉 ---

You can get the full sources for all the code on the running VM in a directory called `output/` with: `docker run -it -v /etc:/hostetc -v /lib:/lib -v $(PWD)/output:/output justincormack/mobysources` The kernel patches at present are just the latest upstream aufs for the kernel version, this may change though next beta.
