I don’t know what your network setup is, but there are no ‘unusual’ requirements for MicroK8s/Kubeflow.
Hi, @evilnick
I am using microk8s 1.21/stable, and microk8s.juju(–version 2.9.10-ubuntu-amd64).
I am stucking in cmd “juju bootstrap microk8s”.
ERROR preferred storage “microk8s.io/hostpath” not available
Is there any config for juju bootstrap or something I missed out?
Hope to hear your suggestions.
Hello,
You’ll need to run microk8s enable storage dns
first, but you should install the latest juju snap using sudo snap install juju --classic
and use that, not the juju in microk8s.
Hi, @robgibbon
I have done that cmds.
And I have use microk8s.juju and juju(from snap).
But still stuck in
ERROR preferred storage “microk8s.io/hostpath” not available Is there anying I missed out?
Thanks for your reply.
Hello again,
Sometimes it can take a while until MicroK8s is ready after you run microk8s enable storage
. Did you run microk8s status --wait-ready
before bootstrapping juju? Maybe try just waiting a bit and then run juju bootstrap microk8s myk8s
again after a few minutes.
Thanks for your reply.@robgibbon All the prerequisite addons are enabled perfectly. But still have the problems.
I’m having problems with this tutorial, I tried to install it exactly with these steps but it seems some of the pods just crash all the time.

Could you please double check your distribution?
P.S. your forum sucks, it thinks those errors contain links so removed dots.
Hello @pttr are you running microk8s in the 1.21/stable
channel? Kubeflow currently doesn’t support any later versions. You can check with snap info microk8s
.
Edit: I’m sorry I was just able to reproduce this with our instructions, there might be something broken on our side, we will try and fix this as soon as possible.
@pttr after further investigation we have discovered that this is an issue with the latest juju version. To bypass this for now, during bootstrap you can do the following:
juju bootstrap microk8s --agent-version="2.9.22"
I have the kubeflow (following your quick guide with ubuntu 20.04) stucked facing this problem: registry.jujucharms.com/kubeflow-charmers/kfp-viz/oci-image@sha256:c90a5818043da47448c4230953b265a66877bd143e4bdd991f762cf47e2a16d6 is not uploding. Running the URL directly in the browser reveals a 404 error, also pinging the address it do not respond .
@alfax1962 thanks for the message. I just ran through everything from scratch again and the only thing I needed that was outside the tutorial was to patch a role for the istio-ingressgateway charm using:
kubectl patch role -n kubeflow istio-ingressgateway-operator -p '{"apiVersion":"rbac.authorization.k8s.io/v1","kind":"Role","metadata":{"name":"istio-ingressgateway-operator"},"rules":[{"apiGroups":["*"],"resources":["*"],"verbs":["*"]}]}'
Did you use the --agent-version="2.9.22"
as @dominik.f mentioned? Apart from that I’m not sure what else might be going wrong. If you could provide juju status
and juju debug-log
info for the failing charm there might be something helpful there. I’d also suggest doing a sudo snap remove microk8s --purge
and trying again - perhaps something was left in microk8s that interacted with this?
Thank you @ca-scribner very much for your prompt reply. All was solved. The problem was my network: the site didn’t answer in the timing required by kubernetes. After some hours the pod initialized correctly. Many regards
You’re welcome! Glad to hear it
The controller can work with different
models
, which map to namespaces in Kubernetes. It is recommended to set up a specific model for Kubeflow:
this is not in fact the case. if you pick any name besides kubeflow
for the model… the kubeflow desktop unit errors out… just heads up
Yeah sorry I thought we had that model name issue covered in this guide, but must have been an old one. Atm there’s a hard-coded assumption in the upstream kubeflow dashboard code that expects kubeflow to deployed in the k8s namespace kubeflow
.
ah, no worries…
Any idea on how or where to access spark in the full bundle ? Posted a ticket to the github here
https://github.com/canonical/bundle-kubeflow/issues/453
I am a total k8s newb so perhaps it’s in the full version but not called out explicitly in the application names or ?
We all start as newbs
I see @dominik.f replied on the issue, but I also subscribed to it so if his suggestion doesn’t work out reply and we can try to sort it out
thank you Andrew, I have actually hit a bug it seems… so I need to tear down the controller and start from scratch… once that’s done I will retry
the bug is described here Bug #1968105 “Juju+microk8s: very weird behaviour” : Bugs : juju
edit: I’ve reconnected my client / controller and done the juju deploy spark-k8s
from there I am a bit lost… going to try to just … load a basic pyspark session… there’s not much documentation on the charmhub about this tho
Edit2: hmmm I seem to have notebooks just scheduling but never getting completed… my juju status shows an error on dex-auth/2
hook failed: "ingress-relation-broken"
Im going to just tear down and start from scratch… and then at the end add juju deploy spark-k8s
and retry
Edit3: well after stopping and restarted the notebook it completed… I then tried a basic hello world NB with pyspark… I am assuming I need to set some… environment variables and point now to the spark-k8s application/unit in juju?
I’ve been trying to port forward or create tunnel to access this dashboard since I installed kubeflow on my server. with the socks tunnel I get an error about the hostname not having an ip associated with it and I don’t know exactly how to deal with it
Hey, try this tutorial for setting up remote access to Kubeflow - Set up remote access | Charmed Kubeflow - hopefully it will help get you going
