# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>&nbsp;[![Build Status](https://travis-ci.org/Sirupsen/logrus.svg?branch=master)](https://travis-ci.org/Sirupsen/logrus)&nbsp;[![godoc reference](https://godoc.org/github.com/Sirupsen/logrus?status.png)][godoc]
Logrus is a structured logger for Go (golang), completely API compatible with
the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
yet stable (pre 1.0). Logrus itself is completely stable and has been used in
many large deployments. The core API is unlikely to change much but please
version control your Logrus to make sure you aren't fetching latest `master` on
every build.**
Nicely color-coded in development (when a TTY is attached, otherwise just
plain text):
![Colored](http://i.imgur.com/PY7qMwd.png)
With `log.Formatter = new(logrus.JSONFormatter)`, for easy parsing by logstash
or Splunk:
```json
{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
{"level":"warning","msg":"The group's number increased tremendously!",
"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
{"animal":"walrus","level":"info","msg":"A giant walrus appears!",
"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}
{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
```
With the default `log.Formatter = new(&log.TextFormatter{})` when a TTY is not
attached, the output is compatible with the
[logfmt](http://godoc.org/github.com/kr/logfmt) format:
```text
time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8

```
#### Example
The simplest way to use Logrus is simply the package-level exported logger:
```go
package main
import (
log "github.com/Sirupsen/logrus"
)
func main() {
log.WithFields(log.Fields{
"animal": "walrus",
}).Info("A walrus appears")
}
```
Note that it's completely api-compatible with the stdlib logger, so you can
replace your `log` imports everywhere with `log "github.com/Sirupsen/logrus"`
and you'll now have the flexibility of Logrus. You can customize it all you
want:
```go
package main
import (
"os"
log "github.com/Sirupsen/logrus"
"github.com/Sirupsen/logrus/hooks/airbrake"
)
func init() {
// Log as JSON instead of the default ASCII formatter.
log.SetFormatter(&log.JSONFormatter{})
// Use the Airbrake hook to report errors that have Error severity or above to
// an exception tracker. You can create custom hooks, see the Hooks section.
log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development"))
// Output to stderr instead of stdout, could also be a file.
log.SetOutput(os.Stderr)
// Only log the warning severity or above.
log.SetLevel(log.WarnLevel)
}
func main() {
log.WithFields(log.Fields{
"animal": "walrus",
"size": 10,
}).Info("A group of walrus emerges from the ocean")
log.WithFields(log.Fields{
"omg": true,
"number": 122,
}).Warn("The group's number increased tremendously!")
log.WithFields(log.Fields{
"omg": true,
"number": 100,
}).Fatal("The ice breaks!")
// A common pattern is to re-use fields between logging statements by re-using
// the logrus.Entry returned from WithFields()
contextLogger := log.WithFields(log.Fields{
"common": "this is a common field",
"other": "I also should be logged always",
})
contextLogger.Info("I'll be logged with common and other field")
contextLogger.Info("Me too")
}
```
For more advanced usage such as logging to multiple locations from the same
application, you can also create an instance of the `logrus` Logger:
```go
package main
import (
"github.com/Sirupsen/logrus"
)
// Create a new instance of the logger. You can have any number of instances.
var log = logrus.New()
func main() {
// The API for setting attributes is a little different than the package level
// exported logger. See Godoc.
log.Out = os.Stderr
log.WithFields(logrus.Fields{
"animal": "walrus",
"size": 10,
}).Info("A group of walrus emerges from the ocean")
}
```
#### Fields
Logrus encourages careful, structured logging though logging fields instead of
long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
to send event %s to topic %s with key %d")`, you should log the much more
discoverable:
```go
log.WithFields(log.Fields{
"event": event,
"topic": topic,
"key": key,
}).Fatal("Failed to send event")
```
We've found this API forces you to think about logging in a way that produces
much more useful logging messages. We've been in countless situations where just
a single added field to a log statement that was already there would've saved us
hours. The `WithFields` call is optional.
In general, with Logrus using any of the `printf`-family functions should be
seen as a hint you should add a field, however, you can still use the
`printf`-family functions with Logrus.
#### Hooks
You can add hooks for logging levels. For example to send errors to an exception
tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
multiple places simultaneously, e.g. syslog.
Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
`init`:
```go
import (
log "github.com/Sirupsen/logrus"
"github.com/Sirupsen/logrus/hooks/airbrake"
logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
"log/syslog"
)
func init() {
log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development"))
hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
if err != nil {
log.Error("Unable to connect to local syslog daemon")
} else {
log.AddHook(hook)
}
}
```
| Hook | Description |
| ----- | ----------- |
| [Airbrake](https://github.com/Sirupsen/logrus/blob/master/hooks/airbrake/airbrake.go) | Send errors to an exception tracking service compatible with the Airbrake API. Uses [`airbrake-go`](https://github.com/tobi/airbrake-go) behind the scenes. |

| [Syslog](https://github.com/Sirupsen/logrus/blob/master/hooks/syslog/syslog.go) | Send errors to remote syslog server. Uses standard library `log/syslog` behind the scenes. |
| [BugSnag](https://github.com/Sirupsen/logrus/blob/master/hooks/bugsnag/bugsnag.go) | Send errors to the Bugsnag exception tracking service. |
| [Sentry](https://github.com/Sirupsen/logrus/blob/master/hooks/sentry/sentry.go) | Send errors to the Sentry error logging and aggregation service. |
| [Hiprus](https://github.com/nubo/hiprus) | Send errors to a channel in hipchat. |
| [Logrusly](https://github.com/sebest/logrusly) | Send logs to [Loggly](https://www.loggly.com/) |
| [Slackrus](https://github.com/johntdyer/slackrus) | Hook for Slack chat. |
| [Journalhook](https://github.com/wercker/journalhook) | Hook for logging to `systemd-journald` |
| [Graylog](https://github.com/gemnasium/logrus-hooks/tree/master/graylog) | Hook for logging to [Graylog](http://graylog2.org/) |
| [Raygun](https://github.com/squirkle/logrus-raygun-hook) | Hook for logging to [Raygun.io](http://raygun.io/) |
| [LFShook](https://github.com/rifflock/lfshook) | Hook for logging to the local filesystem |
| [Honeybadger](https://github.com/agonzalezro/logrus_honeybadger) | Hook for sending exceptions to Honeybadger |
| [Mail](https://github.com/zbindenren/logrus_mail) | Hook for sending exceptions via mail |
| [Rollrus](https://github.com/heroku/rollrus) | Hook for sending errors to rollbar |
| [Fluentd](https://github.com/evalphobia/logrus_fluent) | Hook for logging to fluentd |
| [Mongodb](https://github.com/weekface/mgorus) | Hook for logging to mongodb |
#### Level logging
Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic.
```go
log.Debug("Useful debugging information.")
log.Info("Something noteworthy happened!")
log.Warn("You should probably take a look at this.")
log.Error("Something failed but I'm not quitting.")
// Calls os.Exit(1) after logging
log.Fatal("Bye.")
// Calls panic() after logging
log.Panic("I'm bailing.")
```
You can set the logging level on a `Logger`, then it will only log entries with
that severity or anything above it:
```go
// Will log anything that is info or above (warn, error, fatal, panic). Default.
log.SetLevel(log.InfoLevel)
```
It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
environment if your application has that.
#### Entries
Besides the fields added with `WithField` or `WithFields` some fields are
automatically added to all logging events:
1. `time`. The timestamp when the entry was created.
2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
the `AddFields` call. E.g. `Failed to send event.`
3. `level`. The logging level. E.g. `info`.
#### Environments
Logrus has no notion of environment.
If you wish for hooks and formatters to only be used in specific environments,
you should handle that yourself. For example, if your application has a global
variable `Environment`, which is a string representation of the environment you
could do:
```go
import (
log "github.com/Sirupsen/logrus"
)
init() {
// do something here to set environment depending on an environment variable
// or command-line flag
if Environment == "production" {
log.SetFormatter(&log.JSONFormatter{})
} else {
// The TextFormatter is default, you don't actually have to do this.
log.SetFormatter(&log.TextFormatter{})
}
}
```
This configuration is how `logrus` was intended to be used, but JSON in
production is mostly only useful if you do log aggregation with tools like
Splunk or Logstash.
#### Formatters
The built-in logging formatters are:
* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
without colors.
* *Note:* to force colored output when there is no TTY, set the `ForceColors`
field to `true`. To force no colored output even if there is a TTY set the
`DisableColors` field to `true`
* `logrus.JSONFormatter`. Logs fields as JSON.
* `logrus_logstash.LogstashFormatter`. Logs fields as Logstash Events (http://logstash.net).
```go
logrus.SetFormatter(&logrus_logstash.LogstashFormatter{Type: “application_name"})
```
Third party logging formatters:
* [`zalgo`](https://github.com/aybabtme/logzalgo): invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
You can define your formatter by implementing the `Formatter` interface,
requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
`Fields` type (`map[string]interface{}`) with all your fields as well as the
default ones (see Entries section above):
```go
type MyJSONFormatter struct {
}
log.SetFormatter(new(MyJSONFormatter))
func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) {
// Note this doesn't include Time, Level and Message which are available on
// the Entry. Consult `godoc` on information about those fields or read the
// source of the official loggers.
serialized, err := json.Marshal(entry.Data)
if err != nil {
return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err)
}
return append(serialized, '\n'), nil
}
```
#### Logger as an `io.Writer`
Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
```go
w := logger.Writer()
defer w.Close()
srv := http.Server{
// create a stdlib log.Logger that writes to
// logrus.Logger.
ErrorLog: log.New(w, "", 0),
}
```
Each line written to that writer will be printed the usual way, using formatters
and hooks. The level for those entries is `info`.
#### Rotation
Log rotation is not provided with Logrus. Log rotation should be done by an
external program (like `logrotate(8)`) that can compress and delete old log
entries. It should not be a feature of the application-level logger.

/*
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

// 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.

// Package endpoints provides the types and functionality for defining regions
// and endpoints, as well as querying those definitions.
//
// The SDK's Regions and Endpoints metadata is code generated into the endpoints
// package, and is accessible via the DefaultResolver function. This function
// returns a endpoint Resolver will search the metadata and build an associated
// endpoint if one is found. The default resolver will search all partitions
// known by the SDK. e.g AWS Standard (aws), AWS China (aws-cn), and
// AWS GovCloud (US) (aws-us-gov).
// .
//
// Enumerating Regions and Endpoint Metadata
//
// Casting the Resolver returned by DefaultResolver to a EnumPartitions interface
// will allow you to get access to the list of underlying Partitions with the
// Partitions method. This is helpful if you want to limit the SDK's endpoint
// resolving to a single partition, or enumerate regions, services, and endpoints
// in the partition.
//

// fmt.Println("Services for", p.ID())
// for id, _ := range p.Services() {
// fmt.Println("*", id)
// }
// }
//
// Using Custom Endpoints
//
// The endpoints package also gives you the ability to use your own logic how
// endpoints are resolved. This is a great way to define a custom endpoint
// for select services, without passing that logic down through your code.
//
// If a type implements the Resolver interface it can be used to resolve
// endpoints. To use this with the SDK's Session and Config set the value
// of the type to the EndpointsResolver field of aws.Config when initializing
// the session, or service client.
//
// In addition the ResolverFunc is a wrapper for a func matching the signature
// of Resolver.EndpointFor, converting it to a type that satisfies the

/*
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
SharedConfigEnable 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 := session.Must(session.NewSession())
// Create a Session with a custom region
sess := session.Must(session.NewSession(&aws.Config{
Region: aws.String("us-east-1"),
}))
// Create a S3 client instance from a session
sess := session.Must(session.NewSession())
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.NewSession()
sess := session.Must(session.NewSessionWithOptions(session.Options{
// Options
}))
// Specify profile to load for the session's config
sess := session.Must(session.NewSessionWithOptions(session.Options{
Profile: "profile_name",
}))
// Specify profile for config and region for requests
sess := session.Must(session.NewSessionWithOptions(session.Options{
Config: aws.Config{Region: aws.String("us-east-1")},
Profile: "profile_name",
}))
// Force enable Shared Config support
sess := session.Must(session.NewSessionWithOptions(session.Options{
SharedConfigState: session.SharedConfigEnable,
}))
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 := session.Must(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 config 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 supports assuming
a role with MFA token if the session option AssumeRoleTokenProvider
is set.
role_arn = arn:aws:iam::<account_number>:role/<role_name>
source_profile = profile_with_creds
external_id = 1234
mfa_serial = <serial or mfa arn>
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
Assume Role with MFA token
To create a session with support for assuming an IAM role with MFA set the
session option AssumeRoleTokenProvider to a function that will prompt for the
MFA token code when the SDK assumes the role and refreshes the role's credentials.
This allows you to configure the SDK via the shared config to assumea role
with MFA tokens.
In order for the SDK to assume a role with MFA the SharedConfigState
session option must be set to SharedConfigEnable, or AWS_SDK_LOAD_CONFIG
environment variable set.
The shared configuration instructs the SDK to assume an IAM role with MFA
when the mfa_serial configuration field is set in the shared config
(~/.aws/config) or shared credentials (~/.aws/credentials) file.
If mfa_serial is set in the configuration, the SDK will assume the role, and
the AssumeRoleTokenProvider session option is not set an an error will
be returned when creating the session.
sess := session.Must(session.NewSessionWithOptions(session.Options{
AssumeRoleTokenProvider: stscreds.StdinTokenProvider,
}))
// Create service client value configured for credentials
// from assumed role.
svc := s3.New(sess)
To setup assume role outside of a session see the stscrds.AssumeRoleProvider
documentation.
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
$HOME/.aws/config on Linux/Unix based systems, and
%USERPROFILE%\.aws\config on Windows.
AWS_CONFIG_FILE=$HOME/my_shared_config
Path to a custom Credentials Authority (CA) bundle PEM file that the SDK
will use instead of the default system's root CA bundle. Use this only
if you want to replace the CA bundle the SDK uses for TLS requests.
AWS_CA_BUNDLE=$HOME/my_custom_ca_bundle
Enabling this option will attempt to merge the Transport into the SDK's HTTP

returned. If the Transport's TLS config is set this option will cause the SDK
to overwrite the Transport's TLS config's RootCAs value. If the CA bundle file
contains multiple certificates all of them will be loaded.
The Session option CustomCABundle is also available when creating sessions
to also enable this feature. CustomCABundle session option field has priority
over the AWS_CA_BUNDLE environment variable, and will be used if both are set.
Setting a custom HTTPClient in the aws.Config options will override this setting.
To use this option and custom HTTP client, the HTTP client needs to be provided
when creating the session. Not the service client.

// Package v4 implements signing for AWS V4 signer
//
// Provides request signing for request that need to be signed with
// AWS V4 Signatures.
//
// Standalone Signer
//
// Generally using the signer outside of the SDK should not require any additional
// logic when using Go v1.5 or higher. The signer does this by taking advantage
// of the URL.EscapedPath method. If your request URI requires additional escaping
// you many need to use the URL.Opaque to define what the raw URI should be sent
// to the service as.
//
// The signer will first check the URL.Opaque field, and use its value if set.
// The signer does require the URL.Opaque field to be set in the form of:
//
// "//<hostname>/<path>"
//
// // e.g.
// "//example.com/some/path"
//
// The leading "//" and hostname are required or the URL.Opaque escaping will
// not work correctly.
//
// If URL.Opaque is not set the signer will fallback to the URL.EscapedPath()
// method and using the returned value. If you're using Go v1.4 you must set
// URL.Opaque if the URI path needs escaping. If URL.Opaque is not set with
// Go v1.5 the signer will fallback to URL.Path.
//
// AWS v4 signature validation requires that the canonical string's URI path
// element must be the URI escaped form of the HTTP request's path.
// http://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html
//
// The Go HTTP client will perform escaping automatically on the request. Some
// of these escaping may cause signature validation errors because the HTTP
// request differs from the URI path or query that the signature was generated.
// https://golang.org/pkg/net/url/#URL.EscapedPath
//
// Because of this, it is recommended that when using the signer outside of the
// SDK that explicitly escaping the request prior to being signed is preferable,
// and will help prevent signature validation errors. This can be done by setting
// the URL.Opaque or URL.RawPath. The SDK will use URL.Opaque first and then
// call URL.EscapedPath() if Opaque is not set.
//
// If signing a request intended for HTTP2 server, and you're using Go 1.6.2
// through 1.7.4 you should use the URL.RawPath as the pre-escaped form of the
// request URL. https://github.com/golang/go/issues/16847 points to a bug in
// Go pre 1.8 that fails to make HTTP2 requests using absolute URL in the HTTP
// message. URL.Opaque generally will force Go to make requests with absolute URL.
// URL.RawPath does not do this, but RawPath must be a valid escaping of Path
// or url.EscapedPath will ignore the RawPath escaping.
//
// Test `TestStandaloneSign` provides a complete example of using the signer
// outside of the SDK and pre-escaping the URI path.
