Support for booting ROS on Proxmox VE by docker-machine

[pietrushnic]

RancherOS Version: v1.5.0

Where are you running RancherOS? (docker-machine, AWS, GCE, baremetal, etc.)

docker-machine with Proxmox VE driver.

I would like to boot Rancher OS from ISO and use persistent storage.

Unfortunately, by default Rancher OS does not have qemu-guest-agent enabled, because of that, provisioning through docker-machine cannot succeed.

Solutions that I can imagine at this point are:

1. build my own ISO with enabled qemu-guest-agent service - have no idea how to do that and documentation doesn't seem to help me much with that
2. find another way to determine state and configure machine (e.g. cloud-init?) which is enabled by default since this seems to be an approach of e.g. virtualbox

Please let me know if the above solutions make sense and if not, then I'm open for suggestions.

I didn't try the Proxmox VE driver, but if you want to have qemu-guest-agent enabled, here are my suggestions:

1. update the os-config.tpl.yml

  services_include:
  {{- if eq "true" .AZURE_SERVICE}}
    waagent: true
  {{end -}}
    qemu-guest-agent: true

2. run APPEND_SYSTEM_IMAGES="rancher/os-qemuguestagent:v1.4.0-rc1" make

@niusmallnan hmm, this works, but I was definitely not precise enough since that service have to be up to make any sense :), so one more question how to make it not only enabled but up by default?

[niusmallnan]

@pietrushnic You can cache the service yaml file so that ros can up this service.
Please refer to: https://github.com/rancher/os/blob/master/scripts/layout-initrd#L49-L83

Just add this to your custom branch:

cache_services "q/qemu-guest-agent.yml"

I assume this is hack, if there will be any best practices how those mods should be handled long term please let me know.

Reopen this issue.
I will make it work, but I need some time to try Proxmox VE. I don't know much about it.

[pietrushnic]

@niusmallnan ok, please let me know if I can help you somehow. Have you got Proxmox VE set up?

[niusmallnan]

@kingsd041 Here is something that you can refer to:
My testbranch: https://github.com/niusmallnan/os/tree/qga-enabled
Just run make qemuga

Launch ROS on Proxmox VE via docker-machine is already supported in v1.5.1-rc1
@pietrushnic Thank you for your feedback
