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

This example lives in the pulumi/examples repository. Check out just this directory to use it:

$ git clone --filter=blob:none --sparse https://github.com/pulumi/examples pulumi-examples
$ git -C pulumi-examples sparse-checkout set azure-py-loadbalancer-vm
$ cd pulumi-examples/azure-py-loadbalancer-vm

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
