Ruby Client for the Grafeas API
API Client library for the Grafeas API
The Grafeas API stores, and enables querying and retrieval of, critical metadata about all of your software artifacts.
Actual client classes for the various versions of this API are defined in
versioned client gems, with names of the form
grafeas is the main client library that brings the
verisoned gems in as dependencies, and provides high-level methods for
constructing clients. More information on versioned clients can be found below
in the section titled Which client should I use?.
View the Client Library Documentation for this library, grafeas, to see the convenience methods for constructing client objects. Reference documentation for the client objects themselves can be found in the client library documentation for the versioned client gems: grafeas-v1.
See also the Product Documentation for more usage information.
$ gem install grafeas
Migrating from 0.x versions
The 1.0 release of the grafeas client is a significant upgrade based on a next-gen code generator, and includes substantial interface changes. Existing code written for earlier versions of this library will likely require updates to use this version. See the MIGRATING.md document for more information.
To enable logging for this library, set the logger for the underlying gRPC library.
The logger that you set may be a Ruby stdlib
Logger as shown below,
that will write logs to Cloud Logging. See grpc/logconfig.rb
and the gRPC spec_helper.rb for additional information.
Configuring a Ruby stdlib logger:
require "logger" module MyLogger LOGGER = Logger.new $stderr, level: Logger::WARN def logger LOGGER end end # Define a gRPC module-level logger method before grpc/logconfig.rb loads. module GRPC extend MyLogger end
Supported Ruby Versions
This library is supported on Ruby 2.6+.
Google provides official support for Ruby versions that are actively supported by Ruby Core—that is, Ruby versions that are either in normal maintenance or in security maintenance, and not end of life. Older versions of Ruby may still work, but are unsupported and not recommended. See https://www.ruby-lang.org/en/downloads/branches/ for details about the Ruby support schedule.
Which client should I use?
Most modern Ruby client libraries for Google APIs come in two flavors: the main
client library with a name such as
and lower-level versioned client libraries with names such as
In most cases, you should install the main client.
What's the difference between the main client and a versioned client?
A versioned client provides a basic set of data types and client classes for a single version of a specific service. (That is, for a service with multiple versions, there might be a separate versioned client for each service version.) Most versioned clients are written and maintained by a code generator.
The main client is designed to provide you with the recommended client interfaces for the service. There will be only one main client for any given service, even a service with multiple versions. The main client includes factory methods for constructing the client objects we recommend for most users. In some cases, those will be classes provided by an underlying versioned client; in other cases, they will be handwritten higher-level client objects with additional capabilities, convenience methods, or best practices built in. Generally, the main client will default to a recommended service version, although in some cases you can override this if you need to talk to a specific service version.
Why would I want to use the main client?
We recommend that most users install the main client gem for a service. You can
identify this gem as the one without a version in its name, e.g.
The main client is recommended because it will embody the best practices for
accessing the service, and may also provide more convenient interfaces or
tighter integration into frameworks and third-party libraries. In addition, the
documentation and samples published by Google will generally demonstrate use of
the main client.
Why would I want to use a versioned client?
You can use a versioned client if you are content with a possibly lower-level
class interface, you explicitly want to avoid features provided by the main
client, or you want to access a specific service version not be covered by the
main client. You can identify versioned client gems because the service version
is part of the name, e.g.
What about the google-apis-
Client library gems with names that begin with
google-apis- are based on an
older code generation technology. They talk to a REST/JSON backend (whereas
most modern clients talk to a gRPC backend) and they may
not offer the same performance, features, and ease of use provided by more
google-apis- clients have wide coverage across Google services, so you
might need to use one if there is no modern client available for the service.
However, if a modern client is available, we generally recommend it over the
