1. Secure SSH Key Management for Azure VMs

    Python

    When managing SSH keys for Azure Virtual Machines, it's important to handle keys securely and efficiently. Azure provides a service to store these keys known as SSH Public Keys. The azure-native.compute.SshPublicKey resource in Pulumi allows you to manage these credentials, ensuring your virtual machines are accessible and secure.

    The first step before creating an SSH public key is to ensure that you have a public key to use. This public key is typically generated on your local machine using a tool like ssh-keygen and is the part of the key pair that can be safely shared publicly. The private key, which you should guard carefully, is what you will use to establish secure SSH connections to your VMs.

    Below, you will find a Pulumi program written in Python that provisions an Azure SSH public key resource. This resource will store your public key and can then be associated with Azure Virtual Machines so you can access them using SSH.

    import pulumi import pulumi_azure_native as azure_native # Define the resource group where the SSH public key will reside resource_group = azure_native.resources.ResourceGroup('my-resource-group') # Provision an Azure SSH PublicKey # Note that `public_key` should be the actual SSH public key string. # For example: "ssh-rsa AAAAB3Nza.... your_email@example.com" ssh_public_key = azure_native.compute.SshPublicKey('my-ssh-key', resource_group_name=resource_group.name, location=resource_group.location, public_key="<Your actual SSH public key string here>" ) # Export the id of the SSH public key, which can be useful for other operations, such as # associating it with a specific virtual machine. pulumi.export('ssh_public_key_id', ssh_public_key.id)

    In this program, we create a resource group to house our SSH public key. The azure_native.resources.ResourceGroup class creates a new resource group with the specified name.

    Next, we use the azure_native.compute.SshPublicKey class to create the SSH public key. We provide it a name, associate it with our resource group, specify the location from the resource group, and set the actual public key value.

    Keep in mind that you need to replace <Your actual SSH public key string here> with your actual public key string. This key will be used to authenticate to Azure VMs that you associate this public key with.

    Finally, we export the ID of the SSH public key. This ID can be used in other Pulumi programs or scripts that may need to refer to this SSH public key, perhaps for the creation of VMs that will use this key for authentication.

    Please ensure that you have the Pulumi CLI installed and configured for Azure, and replace the placeholder with your actual SSH public key before running this program.
