Package processcreds is a credential Provider to retrieve `credential_process`
credentials.
WARNING: The following describes a method of sourcing credentials from an external
process. This can potentially be dangerous, so proceed with caution. Other
credential providers should be preferred if at all possible. If using this
option, you should make sure that the config file is as locked down as possible
using security best practices for your operating system.
You can use credentials from a `credential_process` in a variety of ways.
One way is to setup your shared config file, located in the default
location, with the `credential_process` key and the command you want to be
called. You also need to set the AWS_SDK_LOAD_CONFIG environment variable
(e.g., `export AWS_SDK_LOAD_CONFIG=1`) to use the shared config file.
[default]
credential_process = /command/to/call
Creating a new session will use the credential process to retrieve credentials.
NOTE: If there are credentials in the profile you are using, the credential
process will not be used.
// Initialize a session to load credentials.
sess, _ := session.NewSession(&aws.Config{
Region: aws.String("us-east-1")},
)
// Create S3 service client to use the credentials.
svc := s3.New(sess)
Another way to use the `credential_process` method is by using
`credentials.NewCredentials()` and providing a command to be executed to
retrieve credentials:
// Create credentials using the ProcessProvider.
creds := processcreds.NewCredentials("/path/to/command")
// Create service client value configured for credentials.
svc := s3.New(sess, &aws.Config{Credentials: creds})
You can set a non-default timeout for the `credential_process` with another
constructor, `credentials.NewCredentialsTimeout()`, providing the timeout. To
set a one minute timeout:
// Create credentials using the ProcessProvider.
creds := processcreds.NewCredentialsTimeout(
"/path/to/command",
time.Duration(500) * time.Millisecond)
If you need more control, you can set any configurable options in the
credentials using one or more option functions. For example, you can set a two
minute timeout, a credential duration of 60 minutes, and a maximum stdout
buffer size of 2k.
creds := processcreds.NewCredentials(
"/path/to/command",
func(opt *ProcessProvider) {
opt.Timeout = time.Duration(2) * time.Minute
opt.Duration = time.Duration(60) * time.Minute
opt.MaxBufSize = 2048
})
You can also use your own `exec.Cmd`:
// Create an exec.Cmd
myCommand := exec.Command("/path/to/command")
// Create credentials using your exec.Cmd and custom timeout
creds := processcreds.NewCredentialsCommand(
myCommand,
func(opt *processcreds.ProcessProvider) {
opt.Timeout = time.Duration(1) * time.Second
})

/*
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")

// Package csm provides Client Side Monitoring (CSM) which enables sending metrics
// via UDP connection. Using the Start function will enable the reporting of
// metrics on a given port. If Start is called, with different parameters, again,
// a panic will occur.
//
// Pause can be called to pause any metrics publishing on a given port. Sessions
// that have had their handlers modified via InjectHandlers may still be used.
// However, the handlers will act as a no-op meaning no metrics will be published.
//
// Example:
// r, err := csm.Start("clientID", ":31000")
// if err != nil {
// panic(fmt.Errorf("failed starting CSM: %v", err))
// }
//
// sess, err := session.NewSession(&aws.Config{})

// Start returns a Reporter that is used to enable or disable monitoring. If

// 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.
