Load Balancer and Web Server Using Azure Load Balancer and Virtual Machine

View Code

This example deploys an Azure Load Balancer fronting an Azure Virtual Machine and starts an HTTP server on the VM.

Prerequisites

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

Deploying and running the program

1. Create a new stack:

   $ pulumi stack init dev
   

2. Set the required configuration for this example. This example requires you to supply a username and password to the virtual machine that we are going to create.

   $ pulumi config set azure-native:location westus    # any valid Azure region will do
   $ pulumi config set username webmaster
   $ pulumi config set password --secret <your-password>
   

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

3. Run pulumi up to preview and deploy the changes:

   $ pulumi update

4. Get the IP address of the newly-created Load Balancer from the stack’s outputs:

   $ pulumi stack output lb-ip
   137.117.15.111
   

5. Get the FQDN of the newly-created Load Balancer from the stack’s outputs:

   $ pulumi stack output fqdn
   http://azure-py-loadbalancer-vm-n3jtn905.westus2.cloudapp.azure.com
   

6. Check to see that your server is now running:

   $ curl "http://$(pulumi stack output lb-ip)"
   Hello, World!
   
   $ curl "$(pulumi stack output fqdn)"
   Hello, World!
   

7. Destroy the stack:

   $ pulumi destroy --yes
