Add new internal upload target for Google Cloud Platform and osbuild-upload-gcp CLI tool which uses the API. Supported features are: - Authenticate with GCP using explicitly provided JSON credentials file or let the authentication be handled automatically by the Google cloud client library. The later is useful e.g. when the worker is running in GCP VM instance, which has associated permissions with it. - Upload an existing image file into existing Storage bucket. - Verify MD5 checksum of the uploaded image file against the local file's checksum. - Import the uploaded image file into Compute Node as an Image. - Delete the uploaded image file after a successful image import. - Delete all cache files from storage created as part of the image import build job. - Share the imported image with a list of specified accounts. GCP-specific image type is not yet added, since GCP supports importing VMDK and VHD images, which the osbuild-composer already supports. Update go.mod, vendor/ content and SPEC file with new dependencies. Signed-off-by: Tomas Hozza <thozza@redhat.com>

Package cloud is the root of the packages used to access Google Cloud
|
|
Services. See https://godoc.org/cloud.google.com/go for a full list
|
|
of sub-packages.
|
|
|
|
|
|
Client Options
|
|
|
|
All clients in sub-packages are configurable via client options. These options are
|
|
described here: https://godoc.org/google.golang.org/api/option.
|
|
|
|
|
|
Authentication and Authorization
|
|
|
|
All the clients in sub-packages support authentication via Google Application Default
|
|
Credentials (see https://cloud.google.com/docs/authentication/production), or
|
|
by providing a JSON key file for a Service Account. See the authentication examples
|
|
in this package for details.
|
|
|
|
|
|
Timeouts and Cancellation
|
|
|
|
By default, non-streaming methods, like Create or Get, will have a default deadline applied to the
|
|
context provided at call time, unless a context deadline is already set. Streaming
|
|
methods have no default deadline and will run indefinitely. To set timeouts or
|
|
arrange for cancellation, use contexts. See the examples for details. Transient
|
|
errors will be retried when correctness allows.
|
|
|
|
To opt out of default deadlines, set the temporary environment variable
|
|
GOOGLE_API_GO_EXPERIMENTAL_DISABLE_DEFAULT_DEADLINE to "true" prior to client
|
|
creation. This affects all Google Cloud Go client libraries. This opt-out
|
|
mechanism will be removed in a future release. File an issue at
|
|
https://github.com/googleapis/google-cloud-go if the default deadlines
|
|
cannot work for you.
|
|
|
|
Do not attempt to control the initial connection (dialing) of a service by setting a
|
|
timeout on the context passed to NewClient. Dialing is non-blocking, so timeouts
|
|
would be ineffective and would only interfere with credential refreshing, which uses
|
|
the same context.
|
|
|
|
|
|
Connection Pooling
|
|
|
|
Connection pooling differs in clients based on their transport. Cloud
|
|
clients either rely on HTTP or gRPC transports to communicate
|
|
with Google Cloud.
|
|
|
|
Cloud clients that use HTTP (bigquery, compute, storage, and translate) rely on the
|
|
underlying HTTP transport to cache connections for later re-use. These are cached to
|
|
the default http.MaxIdleConns and http.MaxIdleConnsPerHost settings in
|
|
http.DefaultTransport.
|
|
|
|
For gRPC clients (all others in this repo), connection pooling is configurable. Users
|
|
of cloud client libraries may specify option.WithGRPCConnectionPool(n) as a client
|
|
option to NewClient calls. This configures the underlying gRPC connections to be
|
|
pooled and addressed in a round robin fashion.
|
|
|
|
|
|
Using the Libraries with Docker
|
|
|
|
Minimal docker images like Alpine lack CA certificates. This causes RPCs to appear to
|
|
hang, because gRPC retries indefinitely. See https://github.com/googleapis/google-cloud-go/issues/928
|
|
for more information.
|
|
|
|
|
|
Debugging
|
|
|
|
To see gRPC logs, set the environment variable GRPC_GO_LOG_SEVERITY_LEVEL. See
|
|
https://godoc.org/google.golang.org/grpc/grpclog for more information.
|
|
|
|
For HTTP logging, set the GODEBUG environment variable to "http2debug=1" or "http2debug=2".
|
|
|
|
|
|
Client Stability
|
|
|
|
Clients in this repository are considered alpha or beta unless otherwise
|
|
marked as stable in the README.md. Semver is not used to communicate stability
|
|
of clients.
|
|
|
|
Alpha and beta clients may change or go away without notice.
|
|
|
|
Clients marked stable will maintain compatibility with future versions for as
|
|
long as we can reasonably sustain. Incompatible changes might be made in some
|
|
situations, including:
|
|
|
|
- Security bugs may prompt backwards-incompatible changes.
|
|
|
|
- Situations in which components are no longer feasible to maintain without
|
|
making breaking changes, including removal.
|
|
|
|
- Parts of the client surface may be outright unstable and subject to change.
|
|
These parts of the surface will be labeled with the note, "It is EXPERIMENTAL
|
|
and subject to change or removal without notice."
