[Feature] Cluster automatic upgrade for K8s versions

[jluk]

What happened: Today, cluster upgrades require manual intervention and explicit setting of the major.minor.patch versions for Kubernetes. This process must be done at semi-regular intervals to stay within the supported window of Kubernetes versions and would benefit from reduced friction.

What you expected to happen: User is able to opt-in to using automatic upgrades for a given AKS clusterl. The cluster set for auto-upgrade would be upgraded with a newer Kubernetes version in-line with a setting defined by the user which dictates frequency and what the target version should be.

Hi @jluk ,
This is very good news , this will make customer's life easier.
May I suggest that this new feature proposes as well some options to set some upgrade schedule rules , for instance not to perform upgrade/reboot during business hours on production cluster running mission critical apps ? The idea is similar to Kured PR-66 giving new arguments to set a schedule :
--reboot-days, --start-time, --end-time, and --time-zone.

Thanks,
Steve

I came across this issue and saw the announcement in Jan of 2019 (https://azure.microsoft.com/en-us/updates/aks-cluster-auto-upgrade/) that this is being worked on, but the feature isn't even in preview yet, correct?

it seems the current preview version doesn't support setting the timeslot to enable the upgrade? like, I only want to upgrade during weekend.

[tantweiler]

Is there a way to verify to which upgrade channel the cluster has been set?

That seems to be covered by this feature: https://docs.microsoft.com/en-us/azure/aks/planned-maintenance

The document page here doesn't have the "preview" keyword in the title.. does it mean this is GA?

Adding to the last few comments, I'd love to know when this is expected to be GA if it isn't already.

@palma21 Do you know if this in GA? The doc doesn't have preview in the title.

[bergmeister]

@wangyira
Apparently still in preview as of 4 days ago but they plan to GA soon, see #1486 (comment)
