## Description
> Package rconfig implements a CLI configuration reader with struct-embedded defaults, environment variables and posix compatible flag parsing using the [pflag](https://github.com/spf13/pflag) library.
## Installation
Install by running:
```
go get -u github.com/Luzifer/rconfig
```
OR fetch a specific version:
```
go get -u gopkg.in/luzifer/rconfig.v1
```
Run tests by running:
```
go test -v -race -cover github.com/Luzifer/rconfig
```
## Usage
A very simple usecase is to just configure a struct inside the vars section of your `main.go` and to parse the commandline flags from the `main()` function:
```go
package main
import (
"fmt"
"github.com/Luzifer/rconfig"
)
var (
cfg = struct {
Username string `default:"unknown" flag:"user" description:"Your name"`
Details struct {
Age int `default:"25" flag:"age" env:"age" description:"Your age"`
}
}{}
)
func main() {
rconfig.Parse(&cfg)
fmt.Printf("Hello %s, happy birthday for your %dth birthday.",
cfg.Username,
cfg.Details.Age)
}
```
### Provide variable defaults by using a file
Given you have a file `~/.myapp.yml` containing some secrets or usernames (for the example below username is assumed to be "luzifer") as a default configuration for your application you can use this source code to load the defaults from that file using the `vardefault` tag in your configuration struct.
The order of the directives (lower number = higher precedence):
1. Flags provided in command line
1. Environment variables
1. Variable defaults (`vardefault` tag in the struct)
1. `default` tag in the struct
```go
var cfg = struct {
Username string `vardefault:"username" flag:"username" description:"Your username"`
}
func main() {
rconfig.SetVariableDefaults(rconfig.VarDefaultsFromYAMLFile("~/.myapp.yml"))
rconfig.Parse(&cfg)
fmt.Printf("Username = %s", cfg.Username)
// Output: Username = luzifer
}
```
## More info
You can see the full reference documentation of the rconfig package [at godoc.org](https://godoc.org/github.com/Luzifer/rconfig), or through go's standard documentation system by running `godoc -http=:6060` and browsing to [http://localhost:6060/pkg/github.com/Luzifer/rconfig](http://localhost:6060/pkg/github.com/Luzifer/rconfig) after installation.

feedback and contributions from our community. Whether it's a bug report,
new feature, correction, or additional documentation, we welcome your issues
and pull requests. Please read through this document before submitting any
issues or pull requests to ensure we have all the necessary information to
effectively respond to your bug report or contribution.
## Filing Bug Reports
You can file bug reports against the SDK on the [GitHub issues][issues] page.
If you are filing a report for a bug or regression in the SDK, it's extremely
helpful to provide as much information as possible when opening the original
issue. This helps us reproduce and investigate the possible bug without having
to wait for this extra information to be provided. Please read the following
guidelines prior to filing a bug report.
1. Search through existing [issues][] to ensure that your specific issue has
not yet been reported. If it is a common issue, it is likely there is
already a bug report for your problem.
2. Ensure that you have tested the latest version of the SDK. Although you
may have an issue against an older version of the SDK, we cannot provide
bug fixes for old versions. It's also possible that the bug may have been
fixed in the latest release.
3. Provide as much information about your environment, SDK version, and
relevant dependencies as possible. For example, let us know what version
of Go you are using, which and version of the operating system, and the
the environment your code is running in. e.g Container.
4. Provide a minimal test case that reproduces your issue or any error
information you related to your problem. We can provide feedback much
more quickly if we know what operations you are calling in the SDK. If
you cannot provide a full test case, provide as much code as you can
to help us diagnose the problem. Any relevant information should be provided
as well, like whether this is a persistent issue, or if it only occurs
some of the time.
## Submitting Pull Requests
We are always happy to receive code and documentation contributions to the SDK.
Please be aware of the following notes prior to opening a pull request:
1. The SDK is released under the [Apache license][license]. Any code you submit
will be released under that license. For substantial contributions, we may
ask you to sign a [Contributor License Agreement (CLA)][cla].
2. If you would like to implement support for a significant feature that is not
yet available in the SDK, please talk to us beforehand to avoid any
duplication of effort.
3. Wherever possible, pull requests should contain tests as appropriate.
Bugfixes should contain tests that exercise the corrected behavior (i.e., the
test should fail without the bugfix and pass with it), and new features
should be accompanied by tests exercising the feature.
4. Pull requests that contain failing tests will not be merged until the test
failures are addressed. Pull requests that cause a significant drop in the
SDK's test coverage percentage are unlikely to be merged until tests have
been added.
5. The JSON files under the SDK's `models` folder are sourced from outside the SDK.
Such as `models/apis/ec2/2016-11-15/api.json`. We will not accept pull requests
directly on these models. If you discover an issue with the models please
create a [GitHub issue][issues] describing the issue.
### Testing
To run the tests locally, running the `make unit` command will `go get` the
SDK's testing dependencies, and run vet, link and unit tests for the SDK.
```
make unit
```
Standard go testing functionality is supported as well. To test SDK code that
is tagged with `codegen` you'll need to set the build tag in the go test
command. The `make unit` command will do this automatically.
```
go test -tags codegen ./private/...
```
See the `Makefile` for additional testing tags that can be used in testing.
To test on multiple platform the SDK includes several DockerFiles under the
`awstesting/sandbox` folder, and associated make recipes to to execute
unit testing within environments configured for specific Go versions.
```
make sandbox-test-go18
```
To run all sandbox environments use the following make recipe
```
# Optionally update the Go tip that will be used during the batch testing
make update-aws-golang-tip
# Run all SDK tests for supported Go versions in sandboxes
make sandbox-test
```
In addition the sandbox environment include make recipes for interactive modes
so you can run command within the Docker container and context of the SDK.
```
make sandbox-go18
```
### Changelog
You can see all release changes in the `CHANGELOG.md` file at the root of the
repository. The release notes added to this file will contain service client
updates, and major SDK changes.

# AWS SDK for Go
aws-sdk-go is the official AWS SDK for the Go programming language.
Checkout our [release notes](https://github.com/aws/aws-sdk-go/releases) for information about the latest bug fixes, updates, and features added to the SDK.
## Installing
If you are using Go 1.5 with the `GO15VENDOREXPERIMENT=1` vendoring flag, or 1.6 and higher you can use the following command to retrieve the SDK. The SDK's non-testing dependencies will be included and are vendored in the `vendor` folder.
go get -u github.com/aws/aws-sdk-go
Otherwise if your Go environment does not have vendoring support enabled, or you do not want to include the vendored SDK's dependencies you can use the following command to retrieve the SDK and its non-testing dependencies using `go get`.
go get -u github.com/aws/aws-sdk-go/aws/...
go get -u github.com/aws/aws-sdk-go/service/...
If you're looking to retrieve just the SDK without any dependencies use the following command.
go get -d github.com/aws/aws-sdk-go/
These two processes will still include the `vendor` folder and it should be deleted if its not going to be used by your environment.
rm -rf $GOPATH/src/github.com/aws/aws-sdk-go/vendor
## Getting Help
Please use these community resources for getting help. We use the GitHub issues for tracking bugs and feature requests.

## Reference Documentation
[`Getting Started Guide`](https://aws.amazon.com/sdk-for-go/) - This document is a general introduction how to configure and make requests with the SDK. If this is your first time using the SDK, this documentation and the API documentation will help you get started. This document focuses on the syntax and behavior of the SDK. The [Service Developer Guide](https://aws.amazon.com/documentation/) will help you get started using specific AWS services.
[`SDK API Reference Documentation`](https://docs.aws.amazon.com/sdk-for-go/api/) - Use this document to look up all API operation input and output parameters for AWS services supported by the SDK. The API reference also includes documentation of the SDK, and examples how to using the SDK, service client API operations, and API operation require parameters.
[`Service Developer Guide`](https://aws.amazon.com/documentation/) - Use this documentation to learn how to interface with an AWS service. These are great guides both, if you're getting started with a service, or looking for more information on a service. You should not need this document for coding, though in some cases, services may supply helpful samples that you might want to look out for.
[`SDK Examples`](https://github.com/aws/aws-sdk-go/tree/master/example) - Included in the SDK's repo are a several hand crafted examples using the SDK features and AWS services.
## Overview of SDK's Packages
The SDK is composed of two main components, SDK core, and service clients.
The SDK core packages are all available under the aws package at the root of
the SDK. Each client for a supported AWS service is available within its own
package under the service folder at the root of the SDK.
* aws - SDK core, provides common shared types such as Config, Logger,
and utilities to make working with API parameters easier.
* awserr - Provides the error interface that the SDK will use for all
errors that occur in the SDK's processing. This includes service API
response errors as well. The Error type is made up of a code and message.
Cast the SDK's returned error type to awserr.Error and call the Code
method to compare returned error to specific error codes. See the package's
documentation for additional values that can be extracted such as RequestID.
* credentials - Provides the types and built in credentials providers
the SDK will use to retrieve AWS credentials to make API requests with.
Nested under this folder are also additional credentials providers such as
stscreds for assuming IAM roles, and ec2rolecreds for EC2 Instance roles.
* endpoints - Provides the AWS Regions and Endpoints metadata for the SDK.
Use this to lookup AWS service endpoint information such as which services
are in a region, and what regions a service is in. Constants are also provided
for all region identifiers, e.g UsWest2RegionID for "us-west-2".
* session - Provides initial default configuration, and load
configuration from external sources such as environment and shared
credentials file.
* request - Provides the API request sending, and retry logic for the SDK.
This package also includes utilities for defining your own request
retryer, and configuring how the SDK processes the request.
* service - Clients for AWS services. All services supported by the SDK are
available under this folder.
## How to Use the SDK's AWS Service Clients
The SDK includes the Go types and utilities you can use to make requests to
AWS service APIs. Within the service folder at the root of the SDK you'll find
a package for each AWS service the SDK supports. All service clients follows
a common pattern of creation and usage.
When creating a client for an AWS service you'll first need to have a Session
value constructed. The Session provides shared configuration that can be shared
between your service clients. When service clients are created you can pass
in additional configuration via the aws.Config type to override configuration
provided by in the Session to create service client instances with custom
configuration.
Once the service's client is created you can use it to make API requests the
AWS service. These clients are safe to use concurrently.
## Configuring the SDK
In the AWS SDK for Go, you can configure settings for service clients, such
as the log level and maximum number of retries. Most settings are optional;
however, for each service client, you must specify a region and your credentials.
The SDK uses these values to send requests to the correct AWS region and sign
requests with the correct credentials. You can specify these values as part
of a session or as environment variables.
See the SDK's [configuration guide][config_guide] for more information.
See the [session][session_pkg] package documentation for more information on how to use Session
with the SDK.
See the [Config][config_typ] type in the [aws][aws_pkg] package for more information on configuration
options.
[config_guide]: https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html
[session_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/session/
[config_typ]: https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config
[aws_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/
### Configuring Credentials
When using the SDK you'll generally need your AWS credentials to authenticate
with AWS services. The SDK supports multiple methods of supporting these
credentials. By default the SDK will source credentials automatically from
its default credential chain. See the session package for more information
on this chain, and how to configure it. The common items in the credential
chain are the following:
* Environment Credentials - Set of environment variables that are useful
when sub processes are created for specific roles.
* Shared Credentials file (~/.aws/credentials) - This file stores your
credentials based on a profile name and is useful for local development.
* EC2 Instance Role Credentials - Use EC2 Instance Role to assign credentials
to application running on an EC2 instance. This removes the need to manage
credential files in production.
Credentials can be configured in code as well by setting the Config's Credentials
value to a custom provider or using one of the providers included with the
SDK to bypass the default credential chain and use a custom one. This is
helpful when you want to instruct the SDK to only use a specific set of
credentials or providers.
This example creates a credential provider for assuming an IAM role, "myRoleARN"
and configures the S3 service client to use that role for API requests.
```go
// Initial credentials loaded from SDK's default credential chain. Such as
// the environment, shared credentials (~/.aws/credentials), or EC2 Instance
// Role. These credentials will be used to to make the STS Assume Role API.
sess := session.Must(session.NewSession())
// Create the credentials from AssumeRoleProvider to assume the role
// referenced by the "myRoleARN" ARN.
creds := stscreds.NewCredentials(sess, "myRoleArn")
// Create service client value configured for credentials
// from assumed role.
svc := s3.New(sess, &aws.Config{Credentials: creds})
```
See the [credentials][credentials_pkg] package documentation for more information on credential
providers included with the SDK, and how to customize the SDK's usage of
credentials.
The SDK has support for the shared configuration file (~/.aws/config). This
support can be enabled by setting the environment variable, "AWS_SDK_LOAD_CONFIG=1",
or enabling the feature in code when creating a Session via the
Option's SharedConfigState parameter.
```go
sess := session.Must(session.NewSessionWithOptions(session.Options{
SharedConfigState: session.SharedConfigEnable,
}))
```
[credentials_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/credentials
### Configuring AWS Region
In addition to the credentials you'll need to specify the region the SDK
will use to make AWS API requests to. In the SDK you can specify the region
either with an environment variable, or directly in code when a Session or
service client is created. The last value specified in code wins if the region
is specified multiple ways.
To set the region via the environment variable set the "AWS_REGION" to the
region you want to the SDK to use. Using this method to set the region will
allow you to run your application in multiple regions without needing additional
code in the application to select the region.
AWS_REGION=us-west-2
The endpoints package includes constants for all regions the SDK knows. The
values are all suffixed with RegionID. These values are helpful, because they
reduce the need to type the region string manually.
To set the region on a Session use the aws package's Config struct parameter
Region to the AWS region you want the service clients created from the session to
use. This is helpful when you want to create multiple service clients, and
all of the clients make API requests to the same region.
```go
sess := session.Must(session.NewSession(&aws.Config{
Region: aws.String(endpoints.UsWest2RegionID),
}))
```
See the [endpoints][endpoints_pkg] package for the AWS Regions and Endpoints metadata.
In addition to setting the region when creating a Session you can also set
the region on a per service client bases. This overrides the region of a
Session. This is helpful when you want to create service clients in specific
regions different from the Session's region.
```go
svc := s3.New(sess, &aws.Config{
Region: aws.String(endpoints.UsWest2RegionID),
})
```
See the [Config][config_typ] type in the [aws][aws_pkg] package for more information and additional
options such as setting the Endpoint, and other service client configuration options.
[endpoints_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/endpoints/
## Making API Requests
Once the client is created you can make an API request to the service.
Each API method takes a input parameter, and returns the service response
and an error. The SDK provides methods for making the API call in multiple ways.
In this list we'll use the S3 ListObjects API as an example for the different
ways of making API requests.
* ListObjects - Base API operation that will make the API request to the service.
* ListObjectsRequest - API methods suffixed with Request will construct the
API request, but not send it. This is also helpful when you want to get a
presigned URL for a request, and share the presigned URL instead of your
application making the request directly.
* ListObjectsPages - Same as the base API operation, but uses a callback to
automatically handle pagination of the API's response.
* ListObjectsWithContext - Same as base API operation, but adds support for
the Context pattern. This is helpful for controlling the canceling of in
flight requests. See the Go standard library context package for more
information. This method also takes request package's Option functional
options as the variadic argument for modifying how the request will be
made, or extracting information from the raw HTTP response.
* ListObjectsPagesWithContext - same as ListObjectsPages, but adds support for
the Context pattern. Similar to ListObjectsWithContext this method also
takes the request package's Option function option types as the variadic
argument.
In addition to the API operations the SDK also includes several higher level
methods that abstract checking for and waiting for an AWS resource to be in
a desired state. In this list we'll use WaitUntilBucketExists to demonstrate
the different forms of waiters.
* WaitUntilBucketExists. - Method to make API request to query an AWS service for
a resource's state. Will return successfully when that state is accomplished.
* WaitUntilBucketExistsWithContext - Same as WaitUntilBucketExists, but adds
support for the Context pattern. In addition these methods take request
package's WaiterOptions to configure the waiter, and how underlying request
will be made by the SDK.
The API method will document which error codes the service might return for
the operation. These errors will also be available as const strings prefixed
with "ErrCode" in the service client's package. If there are no errors listed
in the API's SDK documentation you'll need to consult the AWS service's API
documentation for the errors that could be returned.
```go
ctx := context.Background()
result, err := svc.GetObjectWithContext(ctx, &s3.GetObjectInput{
Bucket: aws.String("my-bucket"),
Key: aws.String("my-key"),
})
if err != nil {
// Cast err to awserr.Error to handle specific error codes.
aerr, ok := err.(awserr.Error)
if ok && aerr.Code() == s3.ErrCodeNoSuchKey {
// Specific error code handling
}
return err
}
// Make sure to close the body when done with it for S3 GetObject APIs or
// will leak connections.
defer result.Body.Close()
fmt.Println("Object Size:", aws.StringValue(result.ContentLength))
```
### API Request Pagination and Resource Waiters
Pagination helper methods are suffixed with "Pages", and provide the
functionality needed to round trip API page requests. Pagination methods
take a callback function that will be called for each page of the API's response.
```go
objects := []string{}
err := svc.ListObjectsPagesWithContext(ctx, &s3.ListObjectsInput{
Bucket: aws.String(myBucket),
}, func(p *s3.ListObjectsOutput, lastPage bool) bool {
for _, o := range p.Contents {
objects = append(objects, aws.StringValue(o.Key))
}
return true // continue paging
})
if err != nil {
panic(fmt.Sprintf("failed to list objects for bucket, %s, %v", myBucket, err))
}
fmt.Println("Objects in bucket:", objects)
```
Waiter helper methods provide the functionality to wait for an AWS resource
state. These methods abstract the logic needed to to check the state of an
AWS resource, and wait until that resource is in a desired state. The waiter
will block until the resource is in the state that is desired, an error occurs,
or the waiter times out. If a resource times out the error code returned will
be request.WaiterResourceNotReadyErrorCode.
```go
err := svc.WaitUntilBucketExistsWithContext(ctx, &s3.HeadBucketInput{
Bucket: aws.String(myBucket),
})
if err != nil {
aerr, ok := err.(awserr.Error)
if ok && aerr.Code() == request.WaiterResourceNotReadyErrorCode {
fmt.Fprintf(os.Stderr, "timed out while waiting for bucket to exist")
}
panic(fmt.Errorf("failed to wait for bucket to exist, %v", err))
}
fmt.Println("Bucket", myBucket, "exists")
```
## Complete SDK Example
This example shows a complete working Go file which will upload a file to S3
and use the Context pattern to implement timeout logic that will cancel the
request if it takes too long. This example highlights how to use sessions,
create a service client, make a request, handle the error, and process the
response.
```go
package main
import (
"context"
"flag"
"fmt"
"os"
"time"
"github.com/aws/aws-sdk-go/aws"
"github.com/aws/aws-sdk-go/aws/awserr"
"github.com/aws/aws-sdk-go/aws/request"
"github.com/aws/aws-sdk-go/aws/session"
"github.com/aws/aws-sdk-go/service/s3"
)
// Uploads a file to S3 given a bucket and object key. Also takes a duration
// value to terminate the update if it doesn't complete within that time.
//
// The AWS Region needs to be provided in the AWS shared config or on the
// environment variable as `AWS_REGION`. Credentials also must be provided
// Will default to shared config file, but can load from environment if provided.
//
// Usage:
// # Upload myfile.txt to myBucket/myKey. Must complete within 10 minutes or will fail
// go run withContext.go -b mybucket -k myKey -d 10m < myfile.txt
func main() {
var bucket, key string
var timeout time.Duration
flag.StringVar(&bucket, "b", "", "Bucket name.")
flag.StringVar(&key, "k", "", "Object key name.")
flag.DurationVar(&timeout, "d", 0, "Upload timeout.")
flag.Parse()
// All clients require a Session. The Session provides the client with
// shared configuration such as region, endpoint, and credentials. A
// Session should be shared where possible to take advantage of
// configuration and credential caching. See the session package for
// more information.
sess := session.Must(session.NewSession())
// Create a new instance of the service's client with a Session.
// Optional aws.Config values can also be provided as variadic arguments
// to the New function. This option allows you to provide service
// specific configuration.
svc := s3.New(sess)
// Create a context with a timeout that will abort the upload if it takes
// more than the passed in timeout.
ctx := context.Background()
var cancelFn func()
if timeout > 0 {
ctx, cancelFn = context.WithTimeout(ctx, timeout)
}
// Ensure the context is canceled to prevent leaking.
// See context package for more information, https://golang.org/pkg/context/
defer cancelFn()
// Uploads the object to S3. The Context will interrupt the request if the
// timeout expires.
_, err := svc.PutObjectWithContext(ctx, &s3.PutObjectInput{
Bucket: aws.String(bucket),
Key: aws.String(key),
Body: os.Stdin,
})
if err != nil {
if aerr, ok := err.(awserr.Error); ok && aerr.Code() == request.CanceledErrorCode {
// If the SDK can determine the request or retry delay was canceled
// by a context the CanceledErrorCode error code will be returned.
fmt.Fprintf(os.Stderr, "upload canceled due to timeout, %v\n", err)
} else {
fmt.Fprintf(os.Stderr, "failed to upload object, %v\n", err)
}
os.Exit(1)
}
fmt.Printf("successfully uploaded file to %s/%s\n", bucket, key)
}
```

// +build go1.8
// Package plugincreds implements a credentials provider sourced from a Go
// plugin. This package allows you to use a Go plugin to retrieve AWS credentials
// for the SDK to use for service API calls.
//
// As of Go 1.8 plugins are only supported on the Linux platform.
//
// Plugin Symbol Name
//
// The "GetAWSSDKCredentialProvider" is the symbol name that will be used to
// lookup the credentials provider getter from the plugin. If you want to use a
// custom symbol name you should use GetPluginProviderFnsByName to lookup the
// symbol by a custom name.
//
// This symbol is a function that returns two additional functions. One to
// retrieve the credentials, and another to determine if the credentials have
// expired.
//
// Plugin Symbol Signature
//
// The plugin credential provider requires the symbol to match the
// following signature.
//
// func() (RetrieveFn func() (key, secret, token string, err error), IsExpiredFn func() bool)
//
// Plugin Implementation Exmaple
//
// The following is an example implementation of a SDK credential provider using
// the plugin provider in this package. See the SDK's example/aws/credential/plugincreds/plugin
// folder for a runnable example of this.
//
// package main
//
// func main() {}
//
// var myCredProvider provider
//
// // Build: go build -o plugin.so -buildmode=plugin plugin.go
// func init() {
// // Initialize a mock credential provider with stubs
// myCredProvider = provider{"a","b","c"}
// }
//
// // GetAWSSDKCredentialProvider is the symbol SDK will lookup and use to
// // get the credential provider's retrieve and isExpired functions.
// func GetAWSSDKCredentialProvider() (func() (key, secret, token string, err error), func() bool) {
// return myCredProvider.Retrieve, myCredProvider.IsExpired
// }
//
// // mock implementation of a type that returns retrieves credentials and
// // returns if they have expired.
// type provider struct {
// key, secret, token string
// }
//
// func (p provider) Retrieve() (key, secret, token string, err error) {
// return p.key, p.secret, p.token, nil
// }
//
// func (p *provider) IsExpired() bool {
// return false;
// }
//
// Configuring SDK for Plugin Credentials
//
// To configure the SDK to use a plugin's credential provider you'll need to first
// open the plugin file using the plugin standard library package. Once you have
// a handle to the plugin you can use the NewCredentials function of this package
// to create a new credentials.Credentials value that can be set as the
// credentials loader of a Session or Config. See the SDK's example/aws/credential/plugincreds
// folder for a runnable example of this.
//
// // Open plugin, and load it into the process.
// p, err := plugin.Open("somefile.so")
// if err != nil {
// return nil, err
// }
//
// // Create a new Credentials value which will source the provider's Retrieve
// // and IsExpired functions from the plugin.
// creds, err := plugincreds.NewCredentials(p)
// if err != nil {

/*
Package stscreds are credential Providers to retrieve STS AWS credentials.
STS provides multiple ways to retrieve credentials which can be used when making
future AWS service API operation calls.
The SDK will ensure that per instance of credentials.Credentials all requests
to refresh the credentials will be synchronized. But, the SDK is unable to
ensure synchronous usage of the AssumeRoleProvider if the value is shared
between multiple Credentials, Sessions or service clients.
Assume Role
To assume an IAM role using STS with the SDK you can create a new Credentials
with the SDKs's stscreds package.
// Initial credentials loaded from SDK's default credential chain. Such as
// the environment, shared credentials (~/.aws/credentials), or EC2 Instance
// Role. These credentials will be used to to make the STS Assume Role API.
sess := session.Must(session.NewSession())
// Create the credentials from AssumeRoleProvider to assume the role
// referenced by the "myRoleARN" ARN.
creds := stscreds.NewCredentials(sess, "myRoleArn")
// Create service client value configured for credentials
// from assumed role.
svc := s3.New(sess, &aws.Config{Credentials: creds})
Assume Role with static MFA Token
To assume an IAM role with a MFA token you can either specify a MFA token code
directly or provide a function to prompt the user each time the credentials
need to refresh the role's credentials. Specifying the TokenCode should be used
for short lived operations that will not need to be refreshed, and when you do
not want to have direct control over the user provides their MFA token.
With TokenCode the AssumeRoleProvider will be not be able to refresh the role's
credentials.
// Create the credentials from AssumeRoleProvider to assume the role
// referenced by the "myRoleARN" ARN using the MFA token code provided.
creds := stscreds.NewCredentials(sess, "myRoleArn", func(p *stscreds.AssumeRoleProvider) {
p.SerialNumber = aws.String("myTokenSerialNumber")
p.TokenCode = aws.String("00000000")
})
// Create service client value configured for credentials
// from assumed role.
svc := s3.New(sess, &aws.Config{Credentials: creds})
Assume Role with MFA Token Provider
To assume an IAM role with MFA for longer running tasks where the credentials
may need to be refreshed setting the TokenProvider field of AssumeRoleProvider
will allow the credential provider to prompt for new MFA token code when the
role's credentials need to be refreshed.
The StdinTokenProvider function is available to prompt on stdin to retrieve
the MFA token code from the user. You can also implement custom prompts by
satisfing the TokenProvider function signature.
Using StdinTokenProvider with multiple AssumeRoleProviders, or Credentials will
have undesirable results as the StdinTokenProvider will not be synchronized. A
single Credentials with an AssumeRoleProvider can be shared safely.
// Create the credentials from AssumeRoleProvider to assume the role
// referenced by the "myRoleARN" ARN. Prompting for MFA token from stdin.
creds := stscreds.NewCredentials(sess, "myRoleArn", func(p *stscreds.AssumeRoleProvider) {
p.SerialNumber = aws.String("myTokenSerialNumber")
p.TokenProvider = stscreds.StdinTokenProvider
})
// Create service client value configured for credentials
// from assumed role.
svc := s3.New(sess, &aws.Config{Credentials: creds})

// Package aws provides the core SDK's utilities and shared types. Use this package's
// utilities to simplify setting and reading API operations parameters.
//
// Value and Pointer Conversion Utilities
//
// This package includes a helper conversion utility for each scalar type the SDK's
// API use. These utilities make getting a pointer of the scalar, and dereferencing
// a pointer easier.
//
// Each conversion utility comes in two forms. Value to Pointer and Pointer to Value.
// The Pointer to value will safely dereference the pointer and return its value.
// If the pointer was nil, the scalar's zero value will be returned.
//
// The value to pointer functions will be named after the scalar type. So get a
// *string from a string value use the "String" function. This makes it easy to
// to get pointer of a literal string value, because getting the address of a
// literal requires assigning the value to a variable first.
//
// var strPtr *string
//
// // Without the SDK's conversion functions
// str := "my string"
// strPtr = &str
//
// // With the SDK's conversion functions
// strPtr = aws.String("my string")
//
// // Convert *string to string value
// str = aws.StringValue(strPtr)
//
// In addition to scalars the aws package also includes conversion utilities for
// map and slice for commonly types used in API parameters. The map and slice
// conversion functions use similar naming pattern as the scalar conversion
// functions.
//
// var strPtrs []*string
// var strs []string = []string{"Go", "Gophers", "Go"}
//
// // Convert []string to []*string
// strPtrs = aws.StringSlice(strs)
//
// // Convert []*string to []string
// strs = aws.StringValueSlice(strPtrs)
//
// SDK Default HTTP Client
//
// The SDK will use the http.DefaultClient if a HTTP client is not provided to
// the SDK's Session, or service client constructor. This means that if the
// http.DefaultClient is modified by other components of your application the
// modifications will be picked up by the SDK as well.
//
// In some cases this might be intended, but it is a better practice to create
// a custom HTTP Client to share explicitly through your application. You can
// configure the SDK to use the custom HTTP Client by setting the HTTPClient
// value of the SDK's Config type when creating a Session or service client.
