No, we're not switching everything over from Windows... we only need a single VM... to run a single Cyber Recovery application from Dell to manage our fancy new systems. I know, I don't want to hear it, all those decisions were made while I was either still in the hospital, or during the 8 following months when I wanted to die because I couldn't walk. Definitely not looking for a critique of the design or components.
That being said, here are the requirements Dell sent over:
The management host is a physical or VM host. existing hyper-v host
The management host requires the following:
● One of the following operating systems with the latest updates, patches, and security patches:
○ CentOS Linux 7.6, 7.7, 7.8, 7.9, and Stream 8
○ Red Hat Enterprise Linux Version 7.6, 7.7, 7.8, 7.9, and 8.x
○ SUSE Linux Enterprise Server Version 12 SP5● 4 GB RAM
● 200 GB disk space:
○ 1.5 GB free space to extract the Cyber Recovery software
○ 10 GB or more free space for installation of the Cyber Recovery software no problemThe following Docker components are required to install Cyber Recovery software:
● Docker Version 17.06.0, 18.09.7, 19.03.5, 19.03.8, 19.03.12, 19.03.13, 20.10.2, and 20.10.6
NOTE: Red Hat Linux and SUSE Linux Enterprise Server only support Docker Enterprise Edition (EE). CentOS Linux also
supports Docker Community Edition (CE).● Docker Compose Version 1.21, 1.24, 1.25.3,1.25.4, 1.26.2, 1.27.4, and 1.29.1
So my main questions are:
Which OS should I choose?
Where does Docker go in all this? Pre OS? Post OS?
Same question for Docker Compose? -
As I understand it, Docker comes into play after the OS. Between Docker Enterprise Edition and Community Edition, is one supported and not the other for Cyber Recovery? That answer will narrow which of the OSes you pick from the list you gave.
-
@rojoloco you install OS. Then you install Docker. Then you install the app inside docker.
That last step is basically a one line magic command if the developers created a proper docker install.

That's always a huge if in my experience.

Yes it is

So my main questions are:
Which OS should I choose?With those options and limitations, I'd use CentOS Stream 8.
Where does Docker go in all this? Pre OS? Post OS?
It's an application you install, so post OS.
Same question for Docker Compose?
Docker Compose gets installed after Docker. Whichever OS you choose, you should be able to use the Docker and Docker Compose included in the standard repository, but double check the version for yourself.
-
@travisdh1 I suppose the Docker version will whatever we are licensed for. I will double check with the Dell engineers helping with the deployment.

Thanks for the replies everyone. Another stupid question: Should I be installing the workstation version of the OS instead of server?

@rojoloco said in RojoLoco needs your Linux brains!!!:

Just stick with server.
If you do end up needing additional things that are included with the workstation, they can all be added latter. That is another one of those huge if things, very rarely would they be needed.

I'll try to confirm that with Dell. They are slow on the replies.

Keep in mind that these are not different versions as Microsoft treats different versions of things. All they are is a different set of applications/programs installed by default.

I did notice that on a test run of RHEL. Went with server, got no GUI (as expected). Would I have a GUI with workstation? I do need to be able to make it go and maintain it (it's production stuff), I will have server instances in my work lab for the ongoing learning.

You can choose to have a GUI with the server depending on chosen installation options. By default choosing workstation will include Gnome desktop.

I would personally use RHEL or Rocky Linux rather then Centos/Stream

I wouldn't... I prefer not to have ancient.

You are thinking of this wrong.
This is an appliance. Sure it is one you are assembling, but after assembled, it is an appliance.You don't do things to an appliance outside of their designed admin interface.
In this case, you are installing an operating system, and you can set that up to update automatically if you want.
Then you are installing the application's docker image. Once installed, you will only ever be access the application through it's designed interface. Most likely, a web interface.

Gotcha. Wasn't thinking of this as an appliance since it is managing an appliance.

Wow gross that you have to use a specific OS under the containers. You're stuck between a rock and a hard place. Suse needing docker EE (why?) And CentOS/RHEL trying to do their own docker thing. I guess I'd go with CentOS.
Does this have to be compose or can you do k8s?

Not sure, the requirements in the original post are all I know. I have emailed multiple Dell folks for clarification on some stuff, I'll throw that in too.
