  1. Support non-interactive login for AAD-integrated clusters

    Currently if your cluster is integrated with AAD, any kubectl command will prompt you for an interactive login, even after logging in via Azure CLI and obtaining Kubectl credentials using 'az aks get-credentials'.

    This won't work for anything using automation (e.g. a CI server such as Jenkins).

    Ideally one could log in using a service principal who is then mapped to roles using RBAC. Once you are logged in via the Azure CLI, you could obtain the credentials and execute Kubectl commands as normal.

    Original issue here: https://github.com/Azure/AKS/issues/556

    A similar issue was raised here, but I would like to be…

  2. Native integration between AKS and Azure Key Vault

    It makes sense to have some sort of smart integration between kubernetes secrets and azure key vault.

    I.e.
    containers:

        env:
    
    - name: CLIENT_ID
    valueFrom:
    azureSecretKeyRef:
    name: client-details
    key: client-id

  3. Support zero node clusters

    The number of nodes in AKS can not be zero.

    A same request has been opened on GitHub.
    https://github.com/Azure/AKS/issues/52

    Managed Kubenetes services on both of AWS and GCP have the feature. Only Azure does not allow zero node clusters.

    EKS
    https://eksctl.io/usage/autoscaling/#scaling-up-from-0
    https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/FAQ.md#how-can-i-scale-a-node-group-to-0

    GKE
    https://cloud.google.com/kubernetes-engine/docs/concepts/cluster-autoscaler?hl=en

    We can manually deallocate nodes to save money from the Azure portal but in case that we want the capacity increased/decreased automatically as a job scheduler, we expect that the number of nodes is set to zero when there is no use and the size is expanded systematically on demand. Manual operation is not acceptable.

  4. Support selection of nodes to remove when scaling down

    Support selection of nodes to remove when scaling down.
    At the moment when you scale down then the oldest nodes will always stay. Would be a nice feature to be able to remove a selected node when scaling down or maybe manually.

  5. Allow selecting disk type when creating AKS cluster

    There is no way to select disk type (Standard or Premium) when creating an AKS cluster via Portal or Azure CLI, by default Node OS disk type is derived from the selected VM size.

    To be more specific, I want a node StandardB2s with Standard disk. If I create a plain VM, I can select such configuration. If I create an AKS cluster with StandardB2s node, I can stop the node and change the disk type to Standard, but I cannot select Standard_B2s + Standard disk while creating AKS cluster.

  6. low priority VMs (and VMSS)

    It would be really nice if AKS could support low priority VM scale sets.

    It seems that support for VMSS is already in the works and available as a preview.

  7. Support PodPreset alpha feature

    https://kubernetes.io/docs/tasks/inject-data-application/podpreset/

    Some of my current workloads on acs-engine utilize PodPresets to add additional configuration to dynamically created Pods (e.g. by custom controllers which I'm not able to modify submission requests myself). It would be great if AKS would support this as well.

    The two steps required on the apiserver are:

    Adding "settings.k8s.io/v1alpha1=true" in the --runtime-config
    
    Adding PodPreset to --enable-admission-plugins.

    This feature request was moved from https://github.com/Azure/AKS/issues/450

  9. Cluster Autoscaler Integration in portal

    The Cluster Autoscaler(CA) feature which is currently in Preview has CLI support as in the documentation. Is there a backlog item that enables the CA integration in portal as to configure auto scaling policies either during creation of cluster(Day 0) or at a later point of time(Day N ops)?

  10. AKS has a high Log Analytics cost - Azure Monitor for Containers logs every container's perf metrics every 60s

    Enabling Azure Monitor for Containers provides very powerful and useful logging and metrics (e.g. available through Azure Portal). However performance metrics for nodes and every running container are gathered and reported every 60 seconds, which results in very high data ingestion costs in Log Analytics.

    For our Azure bill, the highest cost is VMs (expected), the second highest cost is Log Analytics. We pay far more for logging than we do for SQL Server and CosmosDB data storage and processing combined(!) Looking into this, the main culprit is the Perf table in Log Analytics which is filled with node and…

  11. Support for Azure Monitor Autoscale

    Provide support for Azure Monitor Autoscale that automatically adds instances based on a metric.

    This would allow us to mitigate issues and create awareness about them without any manual action.

    Bonus points if we can remove instances as well.

  12. Make Kubernetes Dashboard available through Azure Portal

    It would be nice if the Kubernetes Dashboard could be reached directly through the Azure Portal instead of creating a local tunnel using kubectl portforward command.

  13. Add a "Start/Stop Cluster" button to the AKS panel and CLI

    To stop an AKS cluster, it is needed to stop all running VM instances in the AKS availability group. Right now there's no way to do this "on the click of a button", to solve this I needed to write a ShellScript (attached to the idea), which stops all running VMs. And this takes a while...

    The idea is to add a "Stop/Start Cluster" button so we can better control the flow of our AKS cluster.

  14. Allow integrating with pre-existing route table

    When deploying AKS with kubenet, you are able to select a pre-existing VNet but are not able to specify a pre-existing route-table. Most organizations require the use of a firewall via a network virtual appliance and thus require use of custom route tables.

    AKS with kubenet deploys a route-table that it creates/manages and updates with new routes for nodes on scale out that it needs.

    Ideally would be better if AKS can optionally integrate with a pre-existing route table associated with the existing VNet, and simply add/remove its routes.

  15. Please add an option to deploy k8s cluster with cpuManagerPolicy static.

    https://kubernetes.io/docs/tasks/administer-cluster/cpu-management-policies/#static-policy

    This option allows cpu pinning to be enabled on containers so that applications that are sensitive to context switches and require strong cpu isolation can benefit from this k8s feature.

    Please check my article regarding performance differences in ScyllaDB for a better understanding of the performance impact.

  16. Add way to query which Feature-Flags are enabled

    From: https://github.com/Azure/AKS/issues/187

    There are workloads that are starting to show up that require certain Kube-api, controller-manager, Scheduler feature flags to be enabled to deploy a specific way. Examples:
    Istio with auto side-car injection - aggregated-API flag
    RBAC - RBAC Flag
    HPA based on customer metrics - aggregated API
    Auditing - audit policy flags

    Perhaps a cli that can list the different flags enabled on the control plane components that are running on a specific cluster:

    az aks get feature-flags -n <aks-resource-name> -g <resourceGroup Name>

    Agin this would just be to query and not change so in selecting possible workloads it…

  17. Custom Domain names or Zones with HTTP Application Routing Feature

    While HTTP Application Routing feature brings a simple and managed ingress with domain management to AKS. Being able to define a custom domain name or a preexisting Azure Zone to be used with the HTTP Application Routing feature would bring more flexibility to the product.

  18. Allow LoadBalancers to bind to Static IPs, created in the AKS Resource Group

    At the moment LoadBalancers can only bind to IPs, created in the automatically created AKS ResourceGroup (the one starting with MC_).

    As I'm not a fan of manually editing automatically created resources. I would like to be able create IPs besides the AKS resource and let my LoadBalancers bind to them.

    Kubernetes federation is not mature at this point. The v1 solution remains in an alpha state, with no path to GA. There is discussion around a V2 approach in sig-multicluster but it is still nascent. As a result, we have no near-term plans to enable it in AKS. If your goal is simply to run the same app across multiple clusters with traffic routing between them, you can mostly accomplish that with a good CI/CD pipeline and Azure Traffic Manager.

  20. IPv6 Container Support in AKS Cluster in Private Azure VNet

    Once K8s has a final release of IPv6 (https://github.com/kubernetes/features/issues/508) I would expect it can be packaged into Azure AKS with integration in CNI, but of this I am not certain.

    I wanted to put this request here formally to track a request to support IPv6 Containers inside an Azure Dual Stack VNet and Subnet.
