AWS v6.81.0 published on Tuesday, May 20, 2025 by Pulumi
pulumi/pulumi-aws

    Provides an AWS EIP Association as a top level resource, to associate and disassociate Elastic IPs from AWS Instances and Network Interfaces.

    NOTE: Do not use this resource to associate an EIP to aws.lb.LoadBalancer or aws.ec2.NatGateway resources. Instead use the allocation_id available in those resources to allow AWS to manage the association, otherwise you will see AuthFailure errors.

    NOTE: aws.ec2.EipAssociation is useful in scenarios where EIPs are either pre-existing or distributed to customers or users and therefore cannot be changed.

    Example Usage

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

const web = new aws.ec2.Instance("web", {
    ami: "ami-21f78e11",
    availabilityZone: "us-west-2a",
    instanceType: aws.ec2.InstanceType.T2_Micro,
    tags: {
        Name: "HelloWorld",
    },
});
const example = new aws.ec2.Eip("example", {domain: "vpc"});
const eipAssoc = new aws.ec2.EipAssociation("eip_assoc", {
    instanceId: web.id,
    allocationId: example.id,
});
