// Package google provides support for making OAuth2 authorized and authenticated
|
|
// HTTP requests to Google APIs. It supports the Web server flow, client-side
|
|
// credentials, service accounts, Google Compute Engine service accounts,
|
|
// Google App Engine service accounts and workload identity federation
|
|
// from non-Google cloud platforms.
|
|
//
|
|
// A brief overview of the package follows. For more information, please read
|
|
// https://developers.google.com/accounts/docs/OAuth2
|
|
// and
|
|
// https://developers.google.com/accounts/docs/application-default-credentials.
|
|
// For more information on using workload identity federation, refer to
|
|
// https://cloud.google.com/iam/docs/how-to#using-workload-identity-federation.
|
|
//
|
|
// OAuth2 Configs
|
|
//
|
|
// Two functions in this package return golang.org/x/oauth2.Config values from Google credential
|
|
// data. Google supports two JSON formats for OAuth2 credentials: one is handled by ConfigFromJSON,
|
|
// the other by JWTConfigFromJSON. The returned Config can be used to obtain a TokenSource or
|
|
// create an http.Client.
|
|
//
|
|
// Workload Identity Federation
|
|
//
|
|
// Using workload identity federation, your application can access Google Cloud
|
|
// resources from Amazon Web Services (AWS), Microsoft Azure or any identity
|
|
// provider that supports OpenID Connect (OIDC).
|
|
// Traditionally, applications running outside Google Cloud have used service
|
|
// account keys to access Google Cloud resources. Using identity federation,
|
|
// you can allow your workload to impersonate a service account.
|
|
// This lets you access Google Cloud resources directly, eliminating the
|
|
// maintenance and security burden associated with service account keys.
|
|
//
|
|
// Follow the detailed instructions on how to configure Workload Identity Federation
|
|
// in various platforms:
|
|
//
|
|
// Amazon Web Services (AWS): https://cloud.google.com/iam/docs/access-resources-aws
|
|
// Microsoft Azure: https://cloud.google.com/iam/docs/access-resources-azure
|
|
// OIDC identity provider: https://cloud.google.com/iam/docs/access-resources-oidc
|
|
//
|
|
// For OIDC providers, the library can retrieve OIDC tokens either from a
|
|
// local file location (file-sourced credentials) or from a local server
|
|
// (URL-sourced credentials).
|
|
// For file-sourced credentials, a background process needs to be continuously
|
|
// refreshing the file location with a new OIDC token prior to expiration.
|
|
// For tokens with one hour lifetimes, the token needs to be updated in the file
|
|
// every hour. The token can be stored directly as plain text or in JSON format.
|
|
// For URL-sourced credentials, a local server needs to host a GET endpoint to
|
|
// return the OIDC token. The response can be in plain text or JSON.
|
|
// Additional required request headers can also be specified.
|
|
//
|
|
//
|
|
// Credentials
|
|
//
|
|
// The Credentials type represents Google credentials, including Application Default
|
|
// Credentials.
|
|
//
|
|
// Use FindDefaultCredentials to obtain Application Default Credentials.
|
|
// FindDefaultCredentials looks in some well-known places for a credentials file, and
|
|
// will call AppEngineTokenSource or ComputeTokenSource as needed.
|
|
//
|
|
// Application Default Credentials also support workload identity federation to
|
|
// access Google Cloud resources from non-Google Cloud platforms including Amazon
|
|
// Web Services (AWS), Microsoft Azure or any identity provider that supports
|
|
// OpenID Connect (OIDC). Workload identity federation is recommended for
|
|
// non-Google Cloud environments as it avoids the need to download, manage and
|
|
// store service account private keys locally.
|
|
//
|
|
// DefaultClient and DefaultTokenSource are convenience methods. They first call FindDefaultCredentials,
|
|
// then use the credentials to construct an http.Client or an oauth2.TokenSource.
|
|
//
|
|
// Use CredentialsFromJSON to obtain credentials from either of the two JSON formats
|
|
// described in OAuth2 Configs, above. The TokenSource in the returned value is the
|
|
// same as the one obtained from the oauth2.Config returned from ConfigFromJSON or
|
|
// JWTConfigFromJSON, but the Credentials may contain additional information
|
|
// that is useful is some circumstances.
