My implementations while taking the Azure Bicep course on Microsoft Learn.

When having multiple sandbox subscriptions, first start by listing them using the following command:

az account list --refresh --query "[?contains(name, 'Concierge Subscription')].id" --output table

Then choose the subsciprion to use by calling:

az account set --subscription <id>

Lastly, specify the default resource group for deployment, which can be seen on the Azure portal:

az configure --defaults group=<id>

Then deploy a template by navigating into its directory and running:

az deployment group create -f .\main.bicep

If the template requires a parameter file, use this command:

az deployment group create -f .\main.bicep --parameters main.parameters.dev.json
