How/where you use Rancher OS? Please share your configuration?

[olljanat]

Rancher OS supports quite a lot of different kind of platforms and configurations. I don't want maintain anything which no one is using so please comment to this issue using template below (copy/paste it to comment and answer to questions) and share how you currently using Rancher OS and/or you are planning to use community maintained version if that configuration would be supported.

I will then based on this feedback remove those non-used parts at least from first version and enable them back later if someone request about them later.

**Where are you running/planning to run Rancher OS/Burmilla OS? (docker-machine, AWS, GCE, baremetal, etc.)**

**Which processor architecture you are using?**

**Do you use some extra hardware? (GPU, etc)?**

**Which console you use (default, ubuntu, centos, etc..)**

**Do you use some service(s) which are not enabled by default?**

**Have you installed some extra tools to console?**

**Do you use some other customizations?**

**Please share copy of your cloud-init (remember remove all sensitive data first)**
<replace with sudo ros config export output>

EDIT: Decisions made so far:

• BurmillaOS development happens on two tracks (decided on Does BurmillaOS need newer kernel version and how it can be provided? #5 (comment))
  • Version 1.9.0 will be running latest 4.14.x kernel and be fully compatible with RancherOS and production ready.
  • Version 2.0.0 will be running next LTS kernel (most probably 5.9.x) and Docker 20.10.x. It also might not be fully production ready because of big jump on versions. Production readiness comes then maybe on 2.1.0, etc.
• Debian console will be set as default and only console to simplify maintenance but still keep mostly used features (decided on Changing default console to Debian and include most common tools to it #9)

Where are you running/planning to run Rancher OS/community maintained version of it? (docker-machine, AWS, GCE, baremetal, etc.)
I would like to ultimately have Rancher run Docker and Kubernetes on a Raspberry PI Model B 8GB. I have initially tried installing everything on the Official Raspberry Pi OS Full (32-bit) from Raspberry Pi themselves.
Which processor architecture you are using?
ARM
Do you use some extra hardware? (GPU, etc)?
I don't believe so; trying to keep everything contained to this one Pi
Which console you use (default, ubuntu, centos, etc..)
ubuntu
Do you use some service(s) which are not enabled by default?
Eventually there would be a VPN service installed, Home Assistant, Pi-Hole, stuff like that
Have you installed some extra tools to console?
nope
Do you use some other customizations?
I don't believe so. Python, Ansible if those count

Special request for @x-jokay @Psayker @jrevillard @etrexel @pierre-emmanuelJ @jianghang8421 @bensallen @drpebcak @mmriis I can see that you have contributed to https://github.com/rancher/os during 2019/2020 and we would like to understand your use cases so we can make sure that those works on BurmillaOS (successor of RancherOS)?

You might be also interested to test our v1.9.0-beta2 version and report findings to #13

And if possible, would be great to have docker-compose as part of the OS available as well 👍🏼
