Azure Aks Generate Ssh Keys
I work as part of a small team, and we would like to use our own ssh keys to administer the kubernetes cluster. I use -generate-ssh-keys which picks up on my idrsa.pub is /.ssh, and I.
All the time that i have tried deploying AKS Cluster i have used the 'node-count' in my command line. Az aks create -resource-group myResourceGroup -name myK8sCluster -node-count 1 -generate-ssh-keys. Nov 19, 2019 generate-ssh-keys; Using these parameters, Azure will create a three-node cluster, running Kubernetes version 1.14.6, with automatically generated ssh keys for the nodes. The ssh keys will be used for secure shell access to the worker nodes. The example below shows the command and its resulting output.
Kubernetes on Microsoft Azure Kubernetes Service (AKS)¶ You can create a Kubernetes cluster either through the Azure portal website, or using the Azure command line tools. This page describes the commands required to setup a Kubernetes cluster using the command line. Return to the terminal session to your container, update the permissions on the copied idrsa private SSH key so that it is user read-only: chmod 0600 idrsa Create an SSH connection to your AKS node. Again, the default username for AKS nodes is azureuser. Accept the prompt to continue with the connection as the SSH key is first trusted.
-->Kubernetes provides a distributed platform for containerized applications. With AKS, you can quickly create a production ready Kubernetes cluster. In this tutorial, part three of seven, a Kubernetes cluster is deployed in AKS. You learn how to:
- Deploy a Kubernetes AKS cluster that can authenticate to an Azure container registry
- Install the Kubernetes CLI (kubectl)
- Configure kubectl to connect to your AKS cluster
In additional tutorials, the Azure Vote application is deployed to the cluster, scaled, and updated.
Before you begin
In previous tutorials, a container image was created and uploaded to an Azure Container Registry instance. If you haven't done these steps, and would like to follow along, start at Tutorial 1 – Create container images.
This tutorial requires that you're running the Azure CLI version 2.0.53 or later. Run az --version to find the version. If you need to install or upgrade, see Install Azure CLI.
Create a Kubernetes cluster
AKS clusters can use Kubernetes role-based access controls (RBAC). These controls let you define access to resources based on roles assigned to users. Permissions are combined if a user is assigned multiple roles, and permissions can be scoped to either a single namespace or across the whole cluster. By default, the Azure CLI automatically enables RBAC when you create an AKS cluster.
Create an AKS cluster using az aks create. The following example creates a cluster named myAKSCluster in the resource group named myResourceGroup. This resource group was created in the previous tutorial. To allow an AKS cluster to interact with other Azure resources, an Azure Active Directory service principal is automatically created, since you did not specify one. Here, this service principal is granted the right to pull images from the Azure Container Registry (ACR) instance you created in the previous tutorial. Note that you can use a managed identity instead of a service principal for easier management.
You can also manually configure a service principal to pull images from ACR. For more information, see ACR authentication with service principals or Authenticate from Kubernetes with a pull secret.
After a few minutes, the deployment completes, and returns JSON-formatted information about the AKS deployment.
Note
To ensure your cluster to operate reliably, you should run at least 2 (two) nodes.
Install the Kubernetes CLI
To connect to the Kubernetes cluster from your local computer, you use kubectl, the Kubernetes command-line client.
If you use the Azure Cloud Shell, kubectl is already installed. You can also install it locally using the az aks install-cli command:
Connect to cluster using kubectl
To configure kubectl to connect to your Kubernetes cluster, use the az aks get-credentials command. The following example gets credentials for the AKS cluster named myAKSCluster in the myResourceGroup:
To verify the connection to your cluster, run the kubectl get nodes command to return a list of the cluster nodes:

In this tutorial, a Kubernetes cluster was deployed in AKS, and you configured kubectl to connect to it. You learned how to:
- Deploy a Kubernetes AKS cluster that can authenticate to an Azure container registry
- Install the Kubernetes CLI (kubectl)
- Configure kubectl to connect to your AKS cluster

-->With a secure shell (SSH) key pair, you can create virtual machines (VMs) in Azure that use SSH keys for authentication, eliminating the need for passwords to sign in. This article shows you how to quickly generate and use an SSH public-private key file pair for Linux VMs. You can complete these steps with the Azure Cloud Shell, a macOS or Linux host, the Windows Subsystem for Linux, and other tools that support OpenSSH.
Note
VMs created using SSH keys are by default configured with passwords disabled, which greatly increases the difficulty of brute-force guessing attacks.
For more background and examples, see Detailed steps to create SSH key pairs.

Supported SSH key formats
Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported.
Create an SSH key pair
Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the ~/.ssh directory. You can specify a different location, and an optional password (passphrase) to access the private key file. If an SSH key pair with the same name exists in the given location, those files are overwritten.
The following command creates an SSH key pair using RSA encryption and a bit length of 4096:
If you use the Azure CLI to create your VM with the az vm create command, you can optionally generate SSH public and private key files using the --generate-ssh-keys option. The key files are stored in the ~/.ssh directory unless specified otherwise with the --ssh-dest-key-path option. The --generate-ssh-keys option will not overwrite existing key files, instead returning an error. In the following command, replace VMname and RGname with your own values:
Provide an SSH public key when deploying a VM
To create a Linux VM that uses SSH keys for authentication, specify your SSH public key when creating the VM using the Azure portal, Azure CLI, Azure Resource Manager templates, or other methods:
If you're not familiar with the format of an SSH public key, you can display your public key with the following cat command, replacing ~/.ssh/id_rsa.pub with the path and filename of your own public key file if needed:
A typical public key value looks like this example:
If you copy and paste the contents of the public key file to use in the Azure portal or a Resource Manager template, make sure you don't copy any trailing whitespace. To copy a public key in macOS, you can pipe the public key file to pbcopy. Similarly in Linux, you can pipe the public key file to programs such as xclip.
The public key that you place on your Linux VM in Azure is by default stored in ~/.ssh/id_rsa.pub, unless you specified a different location when you created the key pair. To use the Azure CLI 2.0 to create your VM with an existing public key, specify the value and optionally the location of this public key using the az vm create command with the --ssh-key-values option. In the following command, replace VMname, RGname, and keyFile with your own values:
If you want to use multiple SSH keys with your VM, you can enter them in a space-separated list, like this --ssh-key-values sshkey-desktop.pub sshkey-laptop.pub.
SSH into your VM
Azure Aks Generate Ssh Keys Linux
With the public key deployed on your Azure VM, and the private key on your local system, SSH into your VM using the IP address or DNS name of your VM. In the following command, replace azureuser and myvm.westus.cloudapp.azure.com with the administrator user name and the fully qualified domain name (or IP address):

If you specified a passphrase when you created your key pair, enter that passphrase when prompted during the login process. The VM is added to your ~/.ssh/known_hosts file, and you won't be asked to connect again until either the public key on your Azure VM changes or the server name is removed from ~/.ssh/known_hosts.
If the VM is using the just-in-time access policy, you need to request access before you can connect to the VM. For more information about the just-in-time policy, see Manage virtual machine access using the just in time policy.
