Azure v6.28.0 published on Friday, Oct 3, 2025 by Pulumi
pulumi/pulumi-azure

    Use this data source to access information about an existing Subnet within a Virtual Network.

    Example Usage

    import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure";

const example = azure.network.getSubnet({
    name: "backend",
    virtualNetworkName: "production",
    resourceGroupName: "networking",
});
export const subnetId = example.then(example => example.id);

    import pulumi
import pulumi_azure as azure

example = azure.network.get_subnet(name="backend",
    virtual_network_name="production",
    resource_group_name="networking")
pulumi.export("subnetId", example.id)

    package main

import (
	"github.com/pulumi/pulumi-azure/sdk/v6/go/azure/network"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		example, err := network.LookupSubnet(ctx, &network.LookupSubnetArgs{
			Name:               "backend",
			VirtualNetworkName: "production",
			ResourceGroupName:  "networking",
		}, nil)
		if err != nil {
			return err
		}
		ctx.Export("subnetId", example.Id)
		return nil
	})
}

    using System.Collections.Generic;
using System.Linq;
using Pulumi;
using Azure = Pulumi.Azure;

return await Deployment.RunAsync(() => 
{
    var example = Azure.Network.GetSubnet.Invoke(new()
    {
        Name = "backend",
        VirtualNetworkName = "production",
        ResourceGroupName = "networking",
    });

    return new Dictionary<string, object?>
    {
        ["subnetId"] = example.Apply(getSubnetResult => getSubnetResult.Id),

    API Providers

    This data source uses the following Azure API Providers:

    • Microsoft.Network - 2024-05-01

    Using getSubnet

    Two invocation forms are available. The direct form accepts plain arguments and either blocks until the result value is available, or returns a Promise-wrapped result. The output form accepts Input-wrapped arguments and returns an Output-wrapped result.

    function getSubnet(args: GetSubnetArgs, opts?: InvokeOptions): Promise<GetSubnetResult>
function getSubnetOutput(args: GetSubnetOutputArgs, opts?: InvokeOptions): Output<GetSubnetResult>
    def get_subnet(name: Optional[str] = None,
               resource_group_name: Optional[str] = None,
               virtual_network_name: Optional[str] = None,
               opts: Optional[InvokeOptions] = None) -> GetSubnetResult
def get_subnet_output(name: Optional[pulumi.Input[str]] = None,
               resource_group_name: Optional[pulumi.Input[str]] = None,
               virtual_network_name: Optional[pulumi.Input[str]] = None,
               opts: Optional[InvokeOptions] = None) -> Output[GetSubnetResult]
    func LookupSubnet(ctx *Context, args *LookupSubnetArgs, opts ...InvokeOption) (*LookupSubnetResult, error)
func LookupSubnetOutput(ctx *Context, args *LookupSubnetOutputArgs, opts ...InvokeOption) LookupSubnetResultOutput

    > Note: This function is named LookupSubnet in the Go SDK.
