Quickstart: Create an Ubuntu Linux virtual machine using a Bicep file
Applies to: ✔️ Linux VMs
This quickstart shows you how to use a Bicep file to deploy an Ubuntu Linux virtual machine (VM) in Azure.
Bicep is a domain-specific language (DSL) that uses declarative syntax to deploy Azure resources. It provides concise syntax, reliable type safety, and support for code reuse. Bicep offers the best authoring experience for your infrastructure-as-code solutions in Azure.
Prerequisites
If you don't have an Azure subscription, create a free account before you begin.
Review the Bicep file
The Bicep file used in this quickstart is from Azure Quickstart Templates.

Several resources are defined in the Bicep file:
- Microsoft.Network/virtualNetworks/subnets: create a subnet.
- Microsoft.Storage/storageAccounts: create a storage account.
- Microsoft.Network/networkInterfaces: create a NIC.
- Microsoft.Network/networkSecurityGroups: create a network security group.
- Microsoft.Network/virtualNetworks: create a virtual network.
- Microsoft.Network/publicIPAddresses: create a public IP address.
- Microsoft.Compute/virtualMachines: create a virtual machine.
Deploy the Bicep file
Save the Bicep file as main.bicep to your local computer.
Deploy the Bicep file using either Azure CLI or Azure PowerShell.
az group create --name exampleRG --location eastus az deployment group create --resource-group exampleRG --template-file main.bicep --parameters adminUsername=<admin-username>Note
Replace <admin-username> with a unique username. You'll also be prompted to enter adminPasswordOrKey.
When the deployment finishes, you should see a message indicating the deployment succeeded.
Cost information isn't presented during the virtual machine creation process for Bicep like it is for the Azure portal. If you want to learn more about how cost works for virtual machines, see the Cost optimization Overview page.
Review deployed resources
Use the Azure portal, Azure CLI, or Azure PowerShell to list the deployed resources in the resource group.
az resource list --resource-group exampleRG
Clean up resources
When no longer needed, use the Azure portal, Azure CLI, or Azure PowerShell to delete the VM and all of the resources in the resource group.
az group delete --name exampleRG
