  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.

      • 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…

        • 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.

          • 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

            • Support for network policies with calico integration

              It would be awesome to have network policies support in AKS to control/restrict network traffic among the Pods and outside world.

              • 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…

                • 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.

                    • 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)?

                      • AKS-API Control Plane Audit Trail - Activity Logs

                        When a user authenticates successfully to the AKS-API we need an audit trail (security log) entry made as well as detail of what commands each user executed and when.
                        This is the type of information we would usually see in an Azure Activity Log, but K8s Master Node activity is not captured there.

                        A workaround for one small part (who is logging on) can be retrieved using AAD reports but this requires premium licensing and its limited to only who logged in, not what they did.

                          • 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:

                                While HTTP Application Routing feature brings a simple and managed ingress with domain management to AKS.

                                • 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

                                  • Ability to change password on Service Principal

                                    By default when AKS cluster is rolled out, default SP with password validity period of 1Y is created. Because masters are hidden for us, we are not able to change password, in order to change it for some sort of security breach, or just to create new one because old one has expired. So by now we have 2 options:
                                    1. Create SP with pass that never expires (not so preferable in terms of security),
                                    2. Create new AKS cluster. But, when you're in production, migrating everything from one cluster to another is not small step. And rolling out new…

                                    • 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.

                                      • 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…

                                            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.
