We need to obtain the subscription ID, tenant ID, client ID, and secrets in order for the Open Service Broker to launch Azure services on our behalf:

1. Run the following command to obtain the required lists:

az account list -o table

2. Copy your subscription ID and save it in an environment variable:

export AZURE_SUBSCRIPTION_ID="<SubscriptionId>"

3. Create a service principal with RBAC enabled so that it can launch Azure services:

az ad sp create-for-rbac --name osba-quickstart -o table

4. Save the values from the command output in the environment variable:

export AZURE_TENANT_ID=<Tenant>
export AZURE_CLIENT_ID=<AppId>
export AZURE_CLIENT_SECRET=<Password>

5. Now we can deploy the Open Service Broker, as follows:

helm repo add azure https://kubernetescharts.blob.core.windows.net/azure
helm install azure/open-service-broker-azure --name osba --namespace osba 
  --set azure.subscriptionId=$AZURE_SUBSCRIPTION_ID 
  --set azure.tenantId=$AZURE_TENANT_ID 
  --set azure.clientId=$AZURE_CLIENT_ID 
  --set azure.clientSecret=$AZURE_CLIENT_SECRETD
