Add customized config: use /mnt (the ephemeral/temp drive) for pod volumes about aks-engine

[m1o1]

Also looking for ephemeral drive support (related: Azure/AKS#105), but we're using AKS, not AKS-engine. I assume the feature would be added somewhere in AKS-engine though

[mwieczorek]

@jackfrancis @CecileRobertMichon any thoughts on that? Is it possible to add it as a customized config?

[mwieczorek]

I tried with:

"kubeletConfig": {
                    "--root-dir": "/mnt"
                }

and it worked (cluster was up and running) (v0.16.1, k8s 1.9.6).
But still kubeconfig and pki folder are left on /var/lib/kubelet

[andyzhangx]

@mwieczorek It's not safe to put kubelet service config into /mnt, since it's a temp disk, the config could be lost after restart.

[mwieczorek]

@andyzhangx true
that's why for me setting "--root-dir" is enough ( I just want to get emptyDir on ephemeral/temp drive)

Is that possible to take a look at this since it's a very common practice on AKS right now. I'm doing it manually on pretty much all of my aks clusters, since 2017 ;) plz guys, add this to ACS Engine.

btw It's also giving a big performance boost to the Docker daemon and logically to the kubernetes cluster in general (thanks to the ephemeral SSD I/O perfs) without any compromises !

We need this ! <3

👋 Thanks for opening your first issue here! If you're reporting a 🐞 bug, please make sure you include steps to reproduce it.

Hi @theobolo, as you may have noticed, the acs-engine project has moved and is now located at https://github.com/Azure/aks-engine. I've transferred your issue to the new issue queue.

[theobolo]

@CecileRobertMichon Thanks Cecile, i wasn't sure ;) since none of thoses related issues seem to have been moved on AKS issue thread, that's a great start !

Is that possible to transfer also all the issues related to this listed on the @andyzhangx page : https://github.com/andyzhangx/Demo/tree/master/acs-engine#change-varlibdocker-to-mnt-which-has-100gb-disk-space

• Azure/acs-engine#1307
• Azure/acs-engine#543

Looking forward for this, cheers.

@theobolo just FYI, AKS Engine is different from AKS see https://github.com/Azure/aks-engine/blob/master/docs/faq.md

[theobolo]

@CecileRobertMichon Thanks, i'm using AKS btw, and i used ACS, but i tought that ACS was used by AKS underlyingly.

There is a lot of issues on the ACS issue thread that are still relevant for AKS today, i just try to dig some of them :P

[CecileRobertMichon]

@theobolo by ACS do you mean acs-engine (the open source project)? acs-engine (now aks-engine) is open source, while ACS (deprecated) and AKS are services, not open source. See the FAQ I sent above for more details.

You should file AKS specific issues (not aks-engine) at https://github.com/Azure/AKS/issues.

[theobolo]

@CecileRobertMichon Yes, to be clear i used ACS-Engine before AKS-engine, now i use AKS-engine but still thoses issues are relevant. I know that ACS-engine is deprecated but the underlying running processes are the same on the new AKS-engine. I think thoses issues are more proposals for additionnal features more than just issues, so i think that the correct git repo to transfer them is AKS-engine repo and not the AKS issue repo.

I'm sorry i was misleading you with my messages but i wasn't aware of all the AKS git repos ... :/
