that certainly a way its used to build up fast deployable services Wheres @pjzedalis when you need him ? ---

With my spare machine, I have 3 partitions. 1 or data and 2 version partitions, so I can boot between the different OSes and still have all my data. My 2012 rMBP has started randomly dying (just goes dead) so it looks like I’ll end up buying back a 16" MBP ☹ Although I’ll just get the bottom of the range machine this time. I intend to apply the same methodology to this machine, split the drive into 3, two different OSes and one data. ---

> [@Meestor\_X](#): > > I don’t know shit about Docker, but what it LOOKs like to me is that it’s for building Linux VMs, not Windows or MacOS VMs? Hmmm. Kind of nope. Docker is a “containerizer”, you ship your app to it and your app gets an isolated userspace, kind of a sandbox. It’s much lighter than VMs. When you launch a VM you are launching an entire system, an OS (guest OS), AND your App that goes on top of this huge thing with a hypervisor enabling it to run at same time as your host OS. Your app will have access to the kernel space (a virtual one, but the kernel). In Docker you create a “bubble”, a “container” (or containers, many of them, if you want) directly on top of your host OS, there’s no guest OS. One OS runs multiple containers sharing it through docker. Between your OS and your App there is Docker tricking your app to think that it is talking to the OS, but it is in an isolated space, your app does not have access to the kernel space. So it can’t erase your C: and destroy your underlying windows (or / in a Unix and destroy it). Well, if you need to crash the OS, maybe ( 😂 ), security profiles define the isolation. But isolated, you can mess your container, and crash your app, but your other apps in other containers will still run without noticing it. When you deploy a windows app container, it needs a windows docker host machine, when you deploy a linux app container, it needs a linux docker host machine. When we deploy VMs, we usually are talking about gigabytes large files, when we deploy containers, maybe few megabytes. ---

Thanks, @Rick.A. I’m afraid, though, I’m still not grokking the docker thing. Or maybe I am, if you’re saying that running Docker will only allow a “bubble” of the host OS? I cannot run a bunch of different OS’s in their own “bubble”? ---

> [@Meestor\_X](#): > > I cannot run a bunch of different OS’s in their own “bubble”? In docker? No. As I said, there’s no guest OS, only a host OS. That’s why containers are thin and VMs are fat. That “bubble” contains only your application and it’s resources. ---

> [@npalardy](#): > > this could be a real pain in the butt It might also cost Apple a chunk of customers, I’ve seen some x-plat developers already state that they’re considering abandoning the Mac, because of weak demand for macOS support, but Apple’s change will mean they have to buy Apple and Brand-X machines to do their work. IMHO, unless Apple’s ARM Macs are inline or better than the competition when they ship, it’s all just marketing covering up for cost cutting. ---

Ok, just so I’m clear, it does not allow me to run multiple OSs, right? ---
