// Package ssocreds provides a credential provider for retrieving temporary AWS
|
|
// credentials using an SSO access token.
|
|
//
|
|
// IMPORTANT: The provider in this package does not initiate or perform the AWS
|
|
// SSO login flow. The SDK provider expects that you have already performed the
|
|
// SSO login flow using AWS CLI using the "aws sso login" command, or by some
|
|
// other mechanism. The provider must find a valid non-expired access token for
|
|
// the AWS SSO user portal URL in ~/.aws/sso/cache. If a cached token is not
|
|
// found, it is expired, or the file is malformed an error will be returned.
|
|
//
|
|
// # Loading AWS SSO credentials with the AWS shared configuration file
|
|
//
|
|
// You can use configure AWS SSO credentials from the AWS shared configuration file by
|
|
// specifying the required keys in the profile and referencing an sso-session:
|
|
//
|
|
// sso_session
|
|
// sso_account_id
|
|
// sso_role_name
|
|
//
|
|
// For example, the following defines a profile "devsso" and specifies the AWS
|
|
// SSO parameters that defines the target account, role, sign-on portal, and
|
|
// the region where the user portal is located. Note: all SSO arguments must be
|
|
// provided, or an error will be returned.
|
|
//
|
|
// [profile devsso]
|
|
// sso_session = dev-session
|
|
// sso_role_name = SSOReadOnlyRole
|
|
// sso_account_id = 123456789012
|
|
//
|
|
// [sso-session dev-session]
|
|
// sso_start_url = https://my-sso-portal.awsapps.com/start
|
|
// sso_region = us-east-1
|
|
// sso_registration_scopes = sso:account:access
|
|
//
|
|
// Using the config module, you can load the AWS SDK shared configuration, and
|
|
// specify that this profile be used to retrieve credentials. For example:
|
|
//
|
|
// config, err := config.LoadDefaultConfig(context.TODO(), config.WithSharedConfigProfile("devsso"))
|
|
// if err != nil {
|
|
// return err
|
|
// }
|
|
//
|
|
// # Programmatically loading AWS SSO credentials directly
|
|
//
|
|
// You can programmatically construct the AWS SSO Provider in your application,
|
|
// and provide the necessary information to load and retrieve temporary
|
|
// credentials using an access token from ~/.aws/sso/cache.
|
|
//
|
|
// ssoClient := sso.NewFromConfig(cfg)
|
|
// ssoOidcClient := ssooidc.NewFromConfig(cfg)
|
|
// tokenPath, err := ssocreds.StandardCachedTokenFilepath("dev-session")
|
|
// if err != nil {
|
|
// return err
|
|
// }
|
|
//
|
|
// var provider aws.CredentialsProvider
|
|
// provider = ssocreds.New(ssoClient, "123456789012", "SSOReadOnlyRole", "https://my-sso-portal.awsapps.com/start", func(options *ssocreds.Options) {
|
|
// options.SSOTokenProvider = ssocreds.NewSSOTokenProvider(ssoOidcClient, tokenPath)
|
|
// })
|
|
//
|
|
// // Wrap the provider with aws.CredentialsCache to cache the credentials until their expire time
|
|
// provider = aws.NewCredentialsCache(provider)
|
|
//
|
|
// credentials, err := provider.Retrieve(context.TODO())
|
|
// if err != nil {
|
|
// return err
|
|
// }
|
|
//
|
|
// It is important that you wrap the Provider with aws.CredentialsCache if you
|
|
// are programmatically constructing the provider directly. This prevents your
|
|
// application from accessing the cached access token and requesting new
|
|
// credentials each time the credentials are used.
