Instructions⌗

Step 1: Build a Packer image⌗

1. To create Azure principle service:⌗

az ad sp create-for-rbac --role contributor --scopes /subscriptions/mySubscriptionID

Take note “appId” and “password” output for next step

2. Create a Resource group:⌗

az group create --name "PackerImage-rg" --location eastus

3. Build Packer template⌗

Open file server.json with your text editor, update these value (from previous):

"client_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx",
"client_secret": "ppppppp-pppp-pppp-pppp-ppppppppppp",
"tenant_id": "zzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz",
"subscription_id": "yyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyy",

Save server.json and run:

packer build server.json

To verify Image has been created, run:

az image list

Step 2: To deploy server cluster⌗

Edit following variables in vars.tf

variables name	default value	description
prefix	azurelabs-nd082	to create resource name, ex: azurelabs-nd082-resource
location	eastus	region of Azure Datacenter
vm_count	2	define how many VM was created (between 2 and 5)

Run:

terraform plan -output solution.plan
terraform apply -auto-approve

Output⌗

The result will output an Public IP Address of Load balancer, open it and you will see nginx default homepage. Well done!

Cleanup Resources⌗

To remove resources, run following command:

terraform destroy -auto-approve
az image delete -g PackerImage-rg -n myPackerImage
az group delete --name PackerImage-rg
