Amazon Web Services (AWS) provider

The Amazon Web Services (AWS) resource provider for Pulumi lets you use AWS resources in your cloud programs. To use
this package, please install the Pulumi CLI first. For a streamlined Pulumi walkthrough, including language runtime installation and AWS configuration, click “Get Started” below.


This package is available in many languages in the standard packaging formats.

Node.js (Java/TypeScript)

To use from JavaScript or TypeScript in Node.js, install using either npm:

$ npm install @pulumi/aws

or yarn:

$ yarn add @pulumi/aws


To use from Python, install using pip:

$ pip install pulumi_aws


To use from Go, use go get to grab the latest version of the library

$ go get


To use from .NET, install using dotnet add package:

$ dotnet add package Pulumi.Aws


The @pulumi/aws package provides a strongly-typed means to create cloud applications that create and interact closely
with AWS resources. Resources are exposed for the entirety of AWS resources and their properties, including (but not
limited to), ‘apigateway’, ‘cloudformation’, ‘EC2’, ‘ECS’, ‘iam’, ‘lambda’, etc. Many convenience APIs have also been
added to make development easier and to help avoid common mistakes, and to get stronger typing.

Serverless Functions

The aws.lambda.CallbackFunction class allows you to create an AWS lambda function directly out of a JavaScript/TypeScript
function object of the right signature. This allows a Pulumi program to simply define a lambda using a simple lambda in
the language of choice, while having Pulumi itself do the appropriate transformation into the final AWS Lambda resource.

This makes many APIs easier to use, such as defining a Lambda to execute when an S3 Bucket is manipulated,
or a CloudWatch timer is fired. To see some examples of this in action, please refer to the examples/ directory.

The pulumi/pulumi-cloud repo offer higher level abstractions that build on top
of this underlying capability.


The following configuration points are available:

  • aws:region – (Required) This is the AWS region.

  • aws:accessKey – (Optional) This is the AWS access key. It can also be sourced from the
    AWS_ACCESS_KEY_ID environment variable, or via a shared credentials file if aws:profile is specified.

  • aws:secretKey – (Optional) This is the AWS secret key. It can also be sourced from the
    AWS_SECRET_ACCESS_KEY environment variable, or via a shared credentials file if aws:profile is specified.

  • aws:profile – (Optional) This is the AWS profile name as set in the shared credentials file.

  • aws:sharedCredentialsFile – (Optional) This is the path to the shared credentials file. If this is not set and
    aws:profile is specified, ~/.aws/credentials will be used.

  • aws:token – (Optional) Session token for validating temporary credentials. Typically provided after successful
    identity federation or Multi-Factor Authentication (MFA) login. With MFA login, this is the session token provided
    afterward, not the 6 digit MFA code used to get temporary credentials. It can also be sourced from the
    AWS_SESSION_TOKEN environment variable.

  • aws:maxRetries – (Optional) This is the maximum number of times an API call is retried, in the case where requests
    are being throttled or experiencing transient failures. The delay between the subsequent API calls increases
    exponentially. If omitted, the default value is 25.

  • aws:allowedAccountIds – (Optional) List of allowed AWS account IDs to prevent you from mistakenly using an incorrect
    one. Conflicts with aws:forbiddenAccountIds.

  • aws:forbiddenAccountIds – (Optional) List of forbidden AWS account IDs to prevent you from mistakenly using the wrong
    one. Conflicts with aws:allowedAccountIds.

  • aws:assumeRole – (Optional) Supports the following (optional) arguments:
    durationSections: Number of seconds to restrict the assume role session duration.
    externalId: External identifier to use when assuming the role.
    policy: IAM Policy JSON describing further restricting permissions for the IAM Role being assumed.
    policyArns: Set of Amazon Resource Names (ARNs) of IAM Policies describing further restricting permissions for the role.
    roleArn: Amazon Resource Name (ARN) of the IAM Role to assume.
    sessionName: Session name to use when assuming the role.
    tags: Map of assume role session tags.

  • aws:insecure – (Optional) Explicitly allow the provider to perform “insecure” SSL requests. If omitted, the default value is false.

  • aws:skipCredentialsValidation – (Optional) Skip the credentials validation via the STS API. Useful for AWS API implementations that do not have STS available or implemented. Default value is true.

  • aws:skipGetEc2Platforms – (Optional) Skip getting the supported EC2 platforms. Used by users that don’t have ec2:DescribeAccountAttributes permissions. Default value is true.

  • aws:skipRegionValidation – (Optional) Skip validation of provided region name. Useful for AWS-like implementations that use their own region names or to bypass the validation for regions that aren’t publicly available yet. Default value is true.

  • aws:skipRequestionAccountId – (Optional) Skip requesting the account ID. Useful for AWS API implementations that do not have the IAM, STS API, or metadata API. Default value is false. When specified, the use of ARNs is compromised as there is no accountID available to construct the ARN.

  • aws:skipMetadataApiCheck – (Optional) Skip the AWS Metadata API check. Useful for AWS API implementations that do not have a metadata API endpoint. This provider from authenticating via the Metadata API by default. You may need to use other authentication methods like static credentials, configuration variables, or environment variables. Default is true.

  • aws:s3ForcePathStyle – (Optional) Set this to true to force the request to use path-style addressing, i.e., By default, the S3 client will use virtual hosted bucket addressing,, when possible. Specific to the Amazon S3 service. Default is false.

Authenticating pulumi-aws via EC2 Instance Metadata?

As of pulumi-aws v3.28.1, the default behaviour for the provider was changed to disable MetadataApiCheck by default. This means,
you need to do either of the following

  1. When using the default provider:

pulumi config set aws:skipMetadataApiCheck false
  1. When using a named provider

const myProvider = new aws.Provider("named-provider", {
  // other config
  skipMetadataApiCheck: false,

var provider = new Aws.Provider("named-provider", new Aws.ProviderArgs
  // other config
  SkipMetadataApiCheck = false,

provider, err := aws.NewProvider(ctx, "named-provider", &aws.ProviderArgs{
    // other config
    SkipMetadataApiCheck: pulumi.Bool(false),

provider = pulumi_aws.Provider('named-provider', skip_metadata_api_check=False)
