  1. Support multiple node pool

    We are currently blocked to using a single node pool in AKS. It would be good to allow us to create new node pool (in different region) and to allow us to have a different VM size (per pool). Google and Amazon are already offering that feature.

  2. Secure AKS API from Public Internet

    Managed K8s in Azure makes the AKS API publically accessible via an Internet endpoint.
    This Master node access is separate from the Agent nodes we stand up inside a VNet and can protect with interior private IPs and NSGs.

    While access to the AKS-API is be protected using Azure DDOS, and integration to AAD and RBAC for user access, some customer security organizations demand either IP whitelisting on it, or some type of if firewalling to limit access to it to only their company. VNet Service Endpoint as another option although not certain can can work. But that kind of…

  4. Please create all the kubernetes related resources in the same resource group.

    The policies in the company don't allow custom naming for azure resource groups. This is really getting the way of using AKS for production use.

  5. Support multiple availability zones for HA (high-availability) clusters

    Allow k8s nodes/agent pool to be created in different/multiple availability zones, to support a highly-available (HA) cluster

  6. 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

  7. 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…

  8. Support for PodSecurityPolicy

    The PodSecurityPolicy admission controller does not seem to be supported. This is a key part of securing a cluster. I see it has previously been raised as an issue, but no feature request was raised. https://github.com/Azure/AKS/issues/327

  9. 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.

    The original request was mentioned here:
    https://github.com/Azure/AKS/issues/290

  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. 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.

  13. 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)?

  14. Changing Node Size in a kubernetes cluster

    Currently we are able to configure the count for Nodes using scale up option in Portal for AKS, Please add an option to change the size of the Nodes. So if required we can resize the node configuration.

  15. Allow changing the Service Principal associated with AKS

    Currently it's impossible to change the Service Principal associated with Azure Kubernetes Service.
    You might want to change the service principal if you're doing big changes in your Azure AD or moving your Azure Subscription to another directory.

  16. Make LsV2 series available on AKS

    Make LsV2 type available on AKS.

    We are creating an k8s operator for ScyllaDB and would like to leverage this powerful hardware (specially because of the NVMes). This would be beneficial not only to our database but to any NoSQL or applications that require fast I/O.

  17. 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.

  18. 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

  19. 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.

  20. 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…
