RandomPet

The resource random.RandomPet generates random pet names that are intended to be used as unique identifiers for other resources.

This resource can be used in conjunction with resources that have the create_before_destroy lifecycle flag set, to avoid conflicts with unique names during the brief period where both the old and new resources exist concurrently.

Example Usage

using Pulumi;
using Aws = Pulumi.Aws;
using Random = Pulumi.Random;

class MyStack : Stack
{
    public MyStack()
    {
        var serverRandomPet = new Random.RandomPet("serverRandomPet", new Random.RandomPetArgs
        {
            Keepers =

                { "ami_id", @var.Ami_id },
            },
        });
        var serverInstance = new Aws.Ec2.Instance("serverInstance", new Aws.Ec2.InstanceArgs
        {
            Ami = serverRandomPet.Keepers.Apply(keepers => keepers.AmiId),
            Tags = 
            {

def RandomPet(resource_name, opts=None, keepers=None, length=None, prefix=None, separator=None, __props__=None);

func NewRandomPet(ctx *Context, name string, args *RandomPetArgs, opts ...ResourceOption) (*RandomPet, error)

public RandomPet(string name, RandomPetArgs? args = null, CustomResourceOptions? opts = null)

name string: The unique name of the resource.
args RandomPetArgs: The arguments to resource properties.
opts CustomResourceOptions: Bag of options to control resource's behavior.

resource_name str: The unique name of the resource.
opts ResourceOptions: A bag of options that control this resource's behavior.

ctx Context: Context object for the current deployment.
name string: The unique name of the resource.
args RandomPetArgs: The arguments to resource properties.

RandomPet Resource Properties

To learn more about resource properties and how to use them, see Inputs and Outputs in the Programming Model docs.

Inputs

The RandomPet resource accepts the following input properties:

Keepers Dictionary<string, object>: Arbitrary map of values that, when changed, will trigger a new id to be generated.
Length int: The length (in words) of the pet name.
Prefix string: A string to prefix the name with.
Separator string: The character to separate words in the pet name.

Keepers map[string]interface{}: Arbitrary map of values that, when changed, will trigger a new id to be generated.
Length int: The length (in words) of the pet name.

length number: The length (in words) of the pet name.
prefix string: A string to prefix the name with.
separator string: The character to separate words in the pet name.

length float: The length (in words) of the pet name.
prefix str: A string to prefix the name with.
