Azure VM Scale Sets

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.

Prerequisites

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. Restore NPM dependencies:

    $ npm install
    
  5. Run pulumi up to preview and deploy changes:

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

    $ pulumi stack output publicAddress
    dsuv3vqbgi.westeurope.cloudapp.azure.com
    $ curl http://$(pulumi stack output publicAddress)
    #nginx welcome screen HTML is returned
