aws.ec2.DefaultSubnet

Provides a resource to manage a default subnet in the current region.

This is an advanced resource and has special caveats to be aware of when using it. Please read this document in its entirety before using this resource.

The aws.ec2.DefaultSubnet resource behaves differently from normal resources in that if a default subnet exists in the specified Availability Zone, this provider does not create this resource, but instead “adopts” it into management. If no default subnet exists, this provider creates a new default subnet. By default, pulumi destroy does not delete the default subnet but does remove the resource from the state. Set the force_destroy argument to true to delete the default subnet.

Example Usage

using System.Collections.Generic;
using Pulumi;
using Aws = Pulumi.Aws;

return await Deployment.RunAsync(() => 
{
    var defaultAz1 = new Aws.Ec2.DefaultSubnet("defaultAz1", new()
    {
        AvailabilityZone = "us-west-2a",
        Tags = 
        {
            { "Name", "Default subnet for us-west-2a" },
        },
    });

});
