Support for sandbox clusters with all feature gates open to allow for testing of new k8s features before they become supported.

Would be awesome to get support for this, looking specifically at the LoadBalancer with Mixed Protocol new feature already mentioned in #2193

Any updates? Ephemeral Containers would be nice, tbh.

Looking forward to use HPAScaleToZero once this is done..

For this you would need at least Containerd 1.5 which is coming only with AKS 1.22+ Clusters

We are also interested in being able to use feature gates to enable alpha features. In our case it's HostProcess container support on k8s 1.22 . Would be very convenient to have way of enabling alpha features.

Looking forward to have support for this, we need this to enable mixed protocols in load balancers.

same here, but i would like a solution where i have to specifically enable alpha feature gates instead of have all enabled.

i agree enabling all of them is way too much compare to selectively enabling individual ones such as MixedProtocolLBSVC hpa scale to zero and a few others.

Agree, we also only need the LoadBalancer with mixed protocols feature. Wouldn't want to also enable every other alpha feature.

I couldn't agree more about feature gates being desirable.

For example, I'd like to be able to start development work on supporting ephemeral containers (https://kubernetes.io/docs/concepts/workloads/pods/ephemeral-containers/) before AKS rolls it out as a fully supported option.

You can do this with AKS 1.23 which is public preview at the moment as ephemeral containers graduated to beta in 1.23

Excellent, thankyou @philwelz . I incorrectly thought beta features were still gated off by default, but upon rechecking I can see I was mistaken.

I already tested with AKS 😄

StatefulSetAutoDeletePVC useful in dev workloads so you don't have a bunch of orphaned pvc's while testing/developing.

back again, we got mixed protocol LB, but now we're interested in HPAContainerMetrics. this issue is really old at this point, it would be nice to either get some commentary from AKS about generally offering alpha-gated k8s features or simply be told "no" and have this issue closed.

thanks!

What are your thoughts if we were to support only latest stable version of AKS for alpha clusters? Would this meet your needs?

If you're wanting to try out alpha features it seems you'd more likely want to test them on the latest preview cluster.

@TilmanLacko-TomTom Is this still something you are interested in? Would like to learn more about your use case and why you are interested in this.

This is something I am interested in as well.
My use case is this:

My microservices work in a choreography architecture, so I only need them to be on if there are work for them to do.
We use devspace to develop, so we have many environments with idle pods running.

Additionally, one of our workloads require 200gb of memory, so if 5 developers each have their own environment they reserve 1 Tb of memory just to have their helm chart deployed, but without having any actual workload.

100% would meet our needs yes. we're happy to upgrade/roll-forward any time we need these things, also happy to flip a specific bit at cluster provisioning time and even totally rebuild our clusters to get features turned on.

This would be fine for me, it shouldn't be an issue to keep our cluster updates to the latest version.

@olsenme: this was added to the backlog on April 13 and then removed again completely on June 5. Does that mean that it's no longer planned?

I'd like to add one more aspect: besides enabling feature gates, sometimes a feature also needs API groups enabled in the apiserver. Example (my current use case): https://kubernetes.io/docs/concepts/scheduling-eviction/dynamic-resource-allocation/#enabling-dynamic-resource-allocation

CAPZ will support creating and joining alpha/beta worker nodes to AKS control plane. For more information see this PR and recorded demo from the community meeting.
If you're interested to use this, functionality please feel free to ping me or join CAPZ office hours or slack
