Azure VM Scale Sets | Python

View Code Deploy

This example provisions a Scale Set of Linux web servers with nginx deployed, configured the auto-scaling based on CPU load, puts a Load Balancer in front of them, and gives it a public IP address.


  1. Install Pulumi
  2. Configure Pulumi for Azure
  3. Configure Pulumi for Python

Running the App

  1. Create a new stack:

    $ pulumi stack init dev
  2. Configure the app deployment.

    $ pulumi config set azure:location westus    # any valid Azure region will do

    Optionally, configure the username and password for the admin user. Otherwise, they will be auto-generated.

    $ pulumi config set adminUser webmaster
    $ pulumi config set adminPassword <your-password> --secret

    Note that --secret ensures your password is encrypted safely.

  3. Login to Azure CLI (you will be prompted to do this during deployment if you forget this step):

    $ az login
  4. Run pulumi up to preview and deploy changes:

    $ pulumi up
    Previewing update:
        13 created
    Update duration: 2m19s
  5. Check the domain name of the PIP:

    $ pulumi stack output publicAddress
    $ curl http://$(pulumi stack output publicAddress)
    #nginx welcome screen HTML is returned
