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
## 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.
## Configuring Credentials
Before using the SDK, ensure that you've configured credentials. The best
way to configure credentials on a development machine is to use the
`~/.aws/credentials` file, which might look like:
```
[default]
aws_access_key_id = AKID1234567890
aws_secret_access_key = MY-SECRET-KEY
```
You can learn more about the credentials file from this
[blog post](http://blogs.aws.amazon.com/security/post/Tx3D6U6WSFGOK2H/A-New-and-Standardized-Way-to-Manage-Credentials-in-the-AWS-SDKs).
Alternatively, you can set the following environment variables:
```
AWS_ACCESS_KEY_ID=AKID1234567890
AWS_SECRET_ACCESS_KEY=MY-SECRET-KEY
```
### AWS shared config file (`~/.aws/config`)
The AWS SDK for Go added support the shared config file in release [v1.3.0](https://github.com/aws/aws-sdk-go/releases/tag/v1.3.0). You can opt into enabling support for the shared config by setting the environment variable `AWS_SDK_LOAD_CONFIG` to a truthy value. See the [Session](https://github.com/aws/aws-sdk-go/wiki/sessions) wiki for more information about this feature.
## Using the Go SDK
To use a service in the SDK, create a service variable by calling the `New()`
function. Once you have a service client, you can call API operations which each
return response data and a possible error.
To list a set of instance IDs from EC2, you could run:
```go
package main
import (
"fmt"

/*
Package session provides configuration for the SDK's service clients.
Sessions can be shared across all service clients that share the same base
configuration. The Session is built from the SDK's default configuration and
request handlers.
Sessions should be cached when possible, because creating a new Session will
load all configuration values from the environment, and config files each time
the Session is created. Sharing the Session value across all of your service
clients will ensure the configuration is loaded the fewest number of times possible.
Concurrency
Sessions are safe to use concurrently as long as the Session is not being
modified. The SDK will not modify the Session once the Session has been created.
Creating service clients concurrently from a shared Session is safe.
Sessions from Shared Config
Sessions can be created using the method above that will only load the
additional config if the AWS_SDK_LOAD_CONFIG environment variable is set.
Alternatively you can explicitly create a Session with shared config enabled.
To do this you can use NewSessionWithOptions to configure how the Session will
be created. Using the NewSessionWithOptions with SharedConfigState set to
SharedConfigEnabled will create the session as if the AWS_SDK_LOAD_CONFIG
environment variable was set.
Creating Sessions
When creating Sessions optional aws.Config values can be passed in that will
override the default, or loaded config values the Session is being created
with. This allows you to provide additional, or case based, configuration
as needed.
By default NewSession will only load credentials from the shared credentials
file (~/.aws/credentials). If the AWS_SDK_LOAD_CONFIG environment variable is
set to a truthy value the Session will be created from the configuration
values from the shared config (~/.aws/config) and shared credentials
(~/.aws/credentials) files. See the section Sessions from Shared Config for
more information.
Create a Session with the default config and request handlers. With credentials
region, and profile loaded from the environment and shared config automatically.
Requires the AWS_PROFILE to be set, or "default" is used.
// Create Session
sess, err := session.NewSession()
// Create a Session with a custom region
sess, err := session.NewSession(&aws.Config{Region: aws.String("us-east-1")})
// Create a S3 client instance from a session
sess, err := session.NewSession()
if err != nil {
// Handle Session creation error
}
svc := s3.New(sess)
Create Session With Option Overrides
In addition to NewSession, Sessions can be created using NewSessionWithOptions.
This func allows you to control and override how the Session will be created
through code instead of being driven by environment variables only.
Use NewSessionWithOptions when you want to provide the config profile, or
override the shared config state (AWS_SDK_LOAD_CONFIG).
// Equivalent to session.New
sess, err := session.NewSessionWithOptions(session.Options{})
// Specify profile to load for the session's config
sess, err := session.NewSessionWithOptions(session.Options{
Profile: "profile_name",
})
// Specify profile for config and region for requests
sess, err := session.NewSessionWithOptions(session.Options{
Config: aws.Config{Region: aws.String("us-east-1")},
Profile: "profile_name",
})
// Force enable Shared Config support
sess, err := session.NewSessionWithOptions(session.Options{
SharedConfigState: SharedConfigEnable,
})
Deprecated "New" function
The New session function has been deprecated because it does not provide good
way to return errors that occur when loading the configuration files and values.
Because of this, the NewWithError
Adding Handlers
You can add handlers to a session for processing HTTP requests. All service
clients that use the session inherit the handlers. For example, the following
handler logs every request and its payload made by a service client:
// Create a session, and add additional handlers for all service
// clients created with the Session to inherit. Adds logging handler.
sess, err := session.NewSession()
sess.Handlers.Send.PushFront(func(r *request.Request) {
// Log every request made and its payload
logger.Println("Request: %s/%s, Payload: %s",
r.ClientInfo.ServiceName, r.Operation, r.Params)
})
Deprecated "New" function
The New session function has been deprecated because it does not provide good
way to return errors that occur when loading the configuration files and values.
Because of this, NewSession was created so errors can be retrieved when
creating a session fails.
Shared Config Fields
By default the SDK will only load the shared credentials file's (~/.aws/credentials)
credentials values, and all other config is provided by the environment variables,
SDK defaults, and user provided aws.Config values.
If the AWS_SDK_LOAD_CONFIG environment variable is set, or SharedConfigEnable
option is used to create the Session the full shared config values will be
loaded. This includes credentials, region, and support for assume role. In
addition the Session will load its configuration from both the shared config
file (~/.aws/config) and shared credentials file (~/.aws/credentials). Both
files have the same format.
If both config files are present the configuration from both files will be
read. The Session will be created from configuration values from the shared
credentials file (~/.aws/credentials) over those in the shared credentials
file (~/.aws/config).
Credentials are the values the SDK should use for authenticating requests with
AWS Services. They arfrom a configuration file will need to include both
aws_access_key_id and aws_secret_access_key must be provided together in the
same file to be considered valid. The values will be ignored if not a complete
group. aws_session_token is an optional field that can be provided if both of
the other two fields are also provided.
aws_access_key_id = AKID
aws_secret_access_key = SECRET
aws_session_token = TOKEN
Assume Role values allow you to configure the SDK to assume an IAM role using
a set of credentials provided in a config file via the source_profile field.
Both "role_arn" and "source_profile" are required. The SDK does not support
assuming a role with MFA token Via the Session's constructor. You can use the
stscreds.AssumeRoleProvider credentials provider to specify custom
configuration and support for MFA.
role_arn = arn:aws:iam::<account_number>:role/<role_name>
source_profile = profile_with_creds
external_id = 1234
mfa_serial = not supported!
role_session_name = session_name
Region is the region the SDK should use for looking up AWS service endpoints
and signing requests.
region = us-east-1
Environment Variables
When a Session is created several environment variables can be set to adjust
how the SDK functions, and what configuration data it loads when creating
Sessions. All environment values are optional, but some values like credentials
require multiple of the values to set or the partial values will be ignored.
All environment variable values are strings unless otherwise noted.
Environment configuration values. If set both Access Key ID and Secret Access
Key must be provided. Session Token and optionally also be provided, but is
not required.
# Access Key ID
AWS_ACCESS_KEY_ID=AKID
AWS_ACCESS_KEY=AKID # only read if AWS_ACCESS_KEY_ID is not set.
# Secret Access Key
AWS_SECRET_ACCESS_KEY=SECRET
AWS_SECRET_KEY=SECRET=SECRET # only read if AWS_SECRET_ACCESS_KEY is not set.
# Session Token
AWS_SESSION_TOKEN=TOKEN
Region value will instruct the SDK where to make service API requests to. If is
not provided in the environment the region must be provided before a service
client request is made.
AWS_REGION=us-east-1
# AWS_DEFAULT_REGION is only read if AWS_SDK_LOAD_CONFIG is also set,
# and AWS_REGION is not also set.
AWS_DEFAULT_REGION=us-east-1
Profile name the SDK should load use when loading shared config from the
configuration files. If not provided "default" will be used as the profile name.
AWS_PROFILE=my_profile
# AWS_DEFAULT_PROFILE is only read if AWS_SDK_LOAD_CONFIG is also set,
# and AWS_PROFILE is not also set.
AWS_DEFAULT_PROFILE=my_profile
SDK load config instructs the SDK to load the shared config in addition to
shared credentials. This also expands the configuration loaded so the shared
credentials will have parity with the shared config file. This also enables
Region and Profile support for the AWS_DEFAULT_REGION and AWS_DEFAULT_PROFILE
env values as well.
AWS_SDK_LOAD_CONFIG=1
Shared credentials file path can be set to instruct the SDK to use an alternative
file for the shared credentials. If not set the file will be loaded from
$HOME/.aws/credentials on Linux/Unix based systems, and
%USERPROFILE%\.aws\credentials on Windows.
AWS_SHARED_CREDENTIALS_FILE=$HOME/my_shared_credentials
Shared config file path can be set to instruct the SDK to use an alternative
file for the shared config. If not set the file will be loaded from
$HOME/.aws/config on Linux/Unix based systems, and
%USERPROFILE%\.aws\config on Windows.

package loader
// This file handles cgo preprocessing of files containing `import "C"`.
//
// DESIGN
//
// The approach taken is to run the cgo processor on the package's
// CgoFiles and parse the output, faking the filenames of the
// resulting ASTs so that the synthetic file containing the C types is
// called "C" (e.g. "~/go/src/net/C") and the preprocessed files
// have their original names (e.g. "~/go/src/net/cgo_unix.go"),
// not the names of the actual temporary files.
//
// The advantage of this approach is its fidelity to 'go build'. The
// downside is that the token.Position.Offset for each AST node is
// incorrect, being an offset within the temporary file. Line numbers
// should still be correct because of the //line comments.
//
// The logic of this file is mostly plundered from the 'go build'
// tool, which also invokes the cgo preprocessor.
//
//
// REJECTED ALTERNATIVE
//
// An alternative approach that we explored is to extend go/types'
// Importer mechanism to provide the identity of the importing package
// so that each time `import "C"` appears it resolves to a different
// synthetic package containing just the objects needed in that case.
// The loader would invoke cgo but parse only the cgo_types.go file
// defining the package-level objects, discarding the other files
// resulting from preprocessing.
//
// The benefit of this approach would have been that source-level
// syntax information would correspond exactly to the original cgo
// file, with no preprocessing involved, making source tools like
// godoc, oracle, and eg happy. However, the approach was rejected
// due to the additional complexity it would impose on go/types. (It
// made for a beautiful demo, though.)
//
// cgo files, despite their *.go extension, are not legal Go source
// files per the specification since they may refer to unexported
// members of package "C" such as C.int. Also, a function such as
// C.getpwent has in effect two types, one matching its C type and one
// which additionally returns (errno C.int). The cgo preprocessor
// uses name mangling to distinguish these two functions in the
// processed code, but go/types would need to duplicate this logic in
// its handling of function calls, analogous to the treatment of map
// lookups in which y=m[k] and y,ok=m[k] are both legal.

// The package defines two primary types: Config, which specifies a

// call to Load() to actually load and type-check the program.

// prog, err := conf.Load()
//
// See examples_test.go for examples of API usage.
//
//
// CONCEPTS AND TERMINOLOGY
//
// The WORKSPACE is the set of packages accessible to the loader. The
// workspace is defined by Config.Build, a *build.Context. The
// default context treats subdirectories of $GOROOT and $GOPATH as
// packages, but this behavior may be overridden.
//
// An AD HOC package is one specified as a set of source files on the
// command line. In the simplest case, it may consist of a single file
// such as $GOROOT/src/net/http/triv.go.
//
// EXTERNAL TEST packages are those comprised of a set of *_test.go
// files all with the same 'package foo_test' declaration, all in the
// same directory. (go/build.Package calls these files XTestFiles.)
//
// An IMPORTABLE package is one that can be referred to by some import
// spec. Every importable package is uniquely identified by its
// PACKAGE PATH or just PATH, a string such as "fmt", "encoding/json",
// or "cmd/vendor/golang.org/x/arch/x86/x86asm". A package path
// typically denotes a subdirectory of the workspace.
//
// An import declaration uses an IMPORT PATH to refer to a package.
// Most import declarations use the package path as the import path.
//
// Due to VENDORING (https://golang.org/s/go15vendor), the
// interpretation of an import path may depend on the directory in which
// it appears. To resolve an import path to a package path, go/build
// must search the enclosing directories for a subdirectory named
// "vendor".
//
// ad hoc packages and external test packages are NON-IMPORTABLE. The
// path of an ad hoc package is inferred from the package
// declarations of its files and is therefore not a unique package key.
// For example, Config.CreatePkgs may specify two initial ad hoc
// packages, both with path "main".
//
// An AUGMENTED package is an importable package P plus all the
// *_test.go files with same 'package foo' declaration as P.
// (go/build.Package calls these files TestFiles.)
//
// The INITIAL packages are those specified in the configuration. A
// DEPENDENCY is a package loaded to satisfy an import in an initial
// package or another dependency.
//
package loader
// IMPLEMENTATION NOTES
//
// 'go test', in-package test files, and import cycles
// ---------------------------------------------------
//
// An external test package may depend upon members of the augmented
// package that are not in the unaugmented package, such as functions
// that expose internals. (See bufio/export_test.go for an example.)
// So, the loader must ensure that for each external test package
// it loads, it also augments the corresponding non-test package.
//
// The import graph over n unaugmented packages must be acyclic; the
// import graph over n-1 unaugmented packages plus one augmented
// package must also be acyclic. ('go test' relies on this.) But the
// import graph over n augmented packages may contain cycles.
//
// First, all the (unaugmented) non-test packages and their
// dependencies are imported in the usual way; the loader reports an
// error if it detects an import cycle.
//
// Then, each package P for which testing is desired is augmented by
// the list P' of its in-package test files, by calling
// (*types.Checker).Files. This arrangement ensures that P' may
// reference definitions within P, but P may not reference definitions
// within P'. Furthermore, P' may import any other package, including
// ones that depend upon P, without an import cycle error.
//
// Consider two packages A and B, both of which have lists of
// in-package test files we'll call A' and B', and which have the
// following import graph edges:
// B imports A
// B' imports A
// A' imports B
// This last edge would be expected to create an error were it not
// for the special type-checking discipline above.
// Cycles of size greater than two are possible. For example:
// compress/bzip2/bzip2_test.go (package bzip2) imports "io/ioutil"
// io/ioutil/tempfile_test.go (package ioutil) imports "regexp"
// regexp/exec_test.go (package regexp) imports "compress/bzip2"
//
//
// Concurrency
// -----------
//
// Let us define the import dependency graph as follows. Each node is a
// list of files passed to (Checker).Files at once. Many of these lists
// are the production code of an importable Go package, so those nodes
// are labelled by the package's path. The remaining nodes are
// ad hoc packages and lists of in-package *_test.go files that augment
// an importable package; those nodes have no label.
//
// The edges of the graph represent import statements appearing within a
// file. An edge connects a node (a list of files) to the node it
// imports, which is importable and thus always labelled.
//
// Loading is controlled by this dependency graph.
//
// To reduce I/O latency, we start loading a package's dependencies
// asynchronously as soon as we've parsed its files and enumerated its
// imports (scanImports). This performs a preorder traversal of the
// import dependency graph.
//
// To exploit hardware parallelism, we type-check unrelated packages in
// parallel, where "unrelated" means not ordered by the partial order of
// the import dependency graph.
//
// We use a concurrency-safe non-blocking cache (importer.imported) to
// record the results of type-checking, whether success or failure. An
// entry is created in this cache by startLoad the first time the
// package is imported. The first goroutine to request an entry becomes
// responsible for completing the task and broadcasting completion to
// subsequent requestors, which block until then.
//
// Type checking occurs in (parallel) postorder: we cannot type-check a
// set of files until we have loaded and type-checked all of their
// immediate dependencies (and thus all of their transitive
// dependencies). If the input were guaranteed free of import cycles,
// this would be trivial: we could simply wait for completion of the
// dependencies and then invoke the typechecker.
//
// But as we saw in the 'go test' section above, some cycles in the
// import graph over packages are actually legal, so long as the
// cycle-forming edge originates in the in-package test files that
// augment the package. This explains why the nodes of the import
// dependency graph are not packages, but lists of files: the unlabelled
// nodes avoid the cycles. Consider packages A and B where B imports A
// and A's in-package tests AT import B. The naively constructed import
// graph over packages would contain a cycle (A+AT) --> B --> (A+AT) but
// the graph over lists of files is AT --> B --> A, where AT is an
// unlabelled node.
//
// Awaiting completion of the dependencies in a cyclic graph would
// deadlock, so we must materialize the import dependency graph (as
// importer.graph) and check whether each import edge forms a cycle. If
// x imports y, and the graph already contains a path from y to x, then
// there is an import cycle, in which case the processing of x must not
// wait for the completion of processing of y.
//
// When the type-checker makes a callback (doImport) to the loader for a
// given import edge, there are two possible cases. In the normal case,
// the dependency has already been completely type-checked; doImport
// does a cache lookup and returns it. In the cyclic case, the entry in
// the cache is still necessarily incomplete, indicating a cycle. We
// perform the cycle check again to obtain the error message, and return
// the error.
//
// The result of using concurrency is about a 2.5x speedup for stdlib_test.
// TODO(adonovan): overhaul the package documentation.

Feature: S3 Integration Crypto Tests
Scenario: Get all plaintext fixtures for symmetric masterkey aes cbc
When I get all fixtures for "aes_gcm" from "aws-s3-shared-tests"
Then I decrypt each fixture against "Java" "version_2"
And I compare the decrypted ciphertext to the plaintext
Scenario: Uploading Go's SDK fixtures
When I get all fixtures for "aes_gcm" from "aws-s3-shared-tests"
Then I encrypt each fixture with "kms" "AWS_SDK_TEST_ALIAS" "us-west-2" and "aes_gcm"
And upload "Go" data with folder "version_2"
