Azure AKS cluster is in Failed state.

Question

J.Tom 26

Hi team,
I was trying to start my cluster (version 1.23.5) but after waiting for 3 hour the process threw an error. ![231863-image.png ]1

Can anyone help or resolve this issue. Currently, I'm unable to find out the real reason behind this issue. Please help.

Regards,
Jiri

Thank you for your heads up.

As per your case description, I would like to say that there are few settings that you can review in order to get this done as it is intended.

-Insufficient subnet (networking) resources

-Insufficient compute (CRP) quota

-Virtual Disk capacity

Is this Windows node or Linux nodes? (Depends on it you may be able to use the Basic Network or Calico like VXLAN)

I hope this can be helpful for you.

Looking forward to hear back from you.

Cheers,

We use Linux nodes.
Those three point seems without problem.
Yesterday if i restarted cluster, one node stucked in pending status with insufficient memory, but at monday AKS started good and everything worked fine.

Hi @J.Tom

Thanks for the answer!

Other settings that be taken in consideration could be the ones that I am about to mention below:

Persistent Volume Claim (PVC)

More nodes in the cluster

Old PODs in stuck or terminating stated can be removed

VMSS using autoscale option

Max number of pods per node OR networking issue due to dynamic allocation IP(Any stuck or terminating pod state not release IP's)

VM sizing issue/Sizing upgrade needed,
