The whole idea of CoreOS is to be the host for a bunch of containers. |
8 |
The host is completely generic - other than maybe configuring things |
9 |
like the network or hardware or things actually related to hosting |
10 |
(what containers to run/how/etc) you aren't suppose to really touch |
11 |
it. You don't install packages on the host. All the stuff you care |
12 |
about goes into the containers. |
13 |
|
14 |
Think of it like VMWare on bare metal, except it is linux and you're |
15 |
running containers and not VMs (so much more efficient, and less |
16 |
secure). |

Again, the point of CoreOS is that you don't care how the host works. |
23 |
You won't add/remove services from the host. As such you won't care |
24 |
what init implementation it runs. |
25 |
|
26 |
The containers are a completely different beast. You might just run |
27 |
your application in the container as PID 1. Or, maybe you run |
28 |
something like sysvinit+openrc or systemd inside a container. You |
29 |
could have one of each running on the same host. |

I have no idea if CoreOS is Gentoo-derived, but it is very much a |
39 |
special-purpose distro. The whole concept is that you put all the |
40 |
value-add in the containers, and then you just want a really standard |
41 |
and lightweight distro to host your containers in. Maybe you run |
42 |
CentOS in one container, and Gentoo in another container, and Debian |
43 |
in another container. |
