Microsoft Azure CLI kubectl plugin

kubectl-az is a set of commands used to troubleshoot Kubernetes clusters in Azure.

Going through the following documentation will help you to understand each available command and which one is the most suitable for your case:

• run-command
• check-apiserver-connectivity

Consider kubectl-az expects the cluster to use virtual machine scale sets. And, commands that allow using --node flag requires the Kubernetes API server to up and running because it is used to retrieve the VMSS instance information of nodes.

However, in case of issues with the Kubernetes API server, we can retrieve the VMSS instance information from the Azure portal and pass it to the commands using the --id flag or separately with the --subscription, --node-resource-group, --vmss and --instance-id flags.

Install

$ git clone https://github.com/Azure/kubectl-az.git
$ cd kubectl-az
# Build and copy the resulting binary in $HOME/.local/bin/
$ make install

Notice it requires Go version 1.17.

Usage

$ kubectl az --help
Microsoft Azure CLI kubectl plugin

Usage:
  kubectl-az [command]

Available Commands:
  check-apiserver-connectivity  Check connectivity between the nodes and the Kubernetes API Server
  completion                    Generate the autocompletion script for the specified shell
  help                          Help about any command
  run-command                   Run a command in a node
  version                       Show version

Flags:
  -h, --help   help for kubectl-az

Use "kubectl-az [command] --help" for more information about a command.

It is necessary to sign in to Azure to run any kubectl-az 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-az will open the default browser and load the Azure sign-in page where you need to authenticate.

Future

• kubectl-az does not store the access token as Azure CLI does. Therefore, unless you sign in using Azure CLI, kubectl-az will request you to authenticate with the default web browser at every execution.
