kubectl-aks is a kubectl plugin that provides a set of commands that enable
users to interact with an AKS cluster even when the control plane is not
functioning as expected. For example, users can still use the plugin to debug
their cluster if the API server is not working correctly. This plugin allows
users to perform various tasks, retrieve information, and execute commands
against the cluster nodes, regardless of the control plane's state.
It's important to note that this plugin does not replace the Azure CLI,
az.
Instead, it complements it by offering additional commands and providing users
with a kubectl-like experience. In practice, users will use az to create and
delete their AKS cluster, and then use kubectl and kubectl-aks to interact
with and debug it.
Going through the following documentation will help you to understand each available command and which one is the most suitable for your case:
Take into account that kubectl-aks expects the cluster to use virtual machine
scale sets, which is the case of an AKS cluster.
You can get the node information needed to execute the commands directly from
the Azure portal or you can let kubectl-aks get
that information for you. If you already have such a information, you can pass
it using the flags or environment variables. If you don't have it, kubectl-aks
can retrieve it either from the Azure API or the Kubernetes API server. If you
expect to use the same node multiple times, it is recommended to import the node
information in the configuration file and set it as the default node, see the
config command for further details.
There is multiple ways to install the kubectl-aks.
krew is the recommended way to install kubectl-aks.
You can follow the krew's
quickstart to install it
and then install kubectl-aks by executing the following command:
kubectl krew install aks
kubectl aks versionIt can be uninstalled using the following command:
kubectl krew uninstall aksIt is possible to download the asset for a given release and platform from the
releases page, uncompress and
move the kubectl-aks executable to any folder in your $PATH.

kubectl aks versionIt can be uninstalled by using the following command:
rm ${HOME}/.local/bin/kubectl-aksTo build kubectl-aks from source, you'll need to have a Golang version 1.17
or higher installed:
git clone https://github.com/Azure/kubectl-aks.git
cd kubectl-aks
# Build and copy the resulting binary in $HOME/.local/bin/
make install

It is necessary to sign in to Azure to run any kubectl-aks command. To do so,
you can use any authentication method provided by the Azure
CLI using the az login command; see
further details
here.
However, if you do not have the Azure CLI or have not signed in yet,
kubectl-aks will open the default browser and load the Azure sign-in page where
you need to authenticate.
In order to run kubectl-aks commands, the user/service principal must have the permissions to perform the
following operations:
- Run command on the instances:
Microsoft.Compute/virtualMachineScaleSets/virtualmachines/runCommand/action - List Virtual Machine Scale Sets (VMSS):
Microsoft.Compute/virtualMachineScaleSets/virtualMachines/read - List Virtual Machine Scale Set Instances (VMSS Instances):
Microsoft.Compute/virtualMachineScaleSets/read
Normally if you are using built-in roles e.g Contributor, you should have the above permissions. However, if you are using custom roles for a service principal, you need to make sure that the permissions are granted.
- az:
kubectl-aksis inspired by the Azure CLI. - azure-sdk-for-net: it is used to interact with the Azure API.
- krew: it is used to distribute
kubectl-aksas a kubectl plugin. - InnovationEngine: it is used to ensure that the documentation is always up to date.
