Google Cloud for Go
NOTE: These packages are experimental, and may occasionally make
backwards-incompatible changes.
NOTE: Github repo is a mirror of https://code.googlesource.com/gocloud.
Go packages for Google Cloud Platform services. Supported APIs include:
- Google Cloud Datastore
- Google Cloud Storage
- Google Cloud Pub/Sub
- Google Cloud Container Engine
import "google.golang.org/cloud"
Documentation and examples are available at
https://godoc.org/google.golang.org/cloud.
Authorization
Authorization, throughout the package, is delegated to the godoc.org/golang.org/x/oauth2.
Refer to the godoc documentation
for examples on using oauth2 with the Cloud package.
Google Cloud Datastore
Google Cloud Datastore (docs) is a fully
managed, schemaless database for storing non-relational data. Cloud Datastore
automatically scales with your users and supports ACID transactions, high availability
of reads and writes, strong consistency for reads and ancestor queries, and eventual
consistency for all other queries.
Follow the activation instructions to use the Google
Cloud Datastore API with your project.
https://godoc.org/google.golang.org/cloud/datastore
type Post struct {
Title string
Body string `datastore:",noindex"`
PublishedAt time.Time
}
keys := []*datastore.Key{
datastore.NewKey(ctx, "Post", "post1", 0, nil),
datastore.NewKey(ctx, "Post", "post2", 0, nil),
}
posts := []*Post{
{Title: "Post 1", Body: "...", PublishedAt: time.Now()},
{Title: "Post 2", Body: "...", PublishedAt: time.Now()},
}
if _, err := datastore.PutMulti(ctx, keys, posts); err != nil {
log.Println(err)
}
Google Cloud Storage
Google Cloud Storage (docs) allows you to store
data on Google infrastructure with very high reliability, performance and availability,
and can be used to distribute large data objects to users via direct download.
https://godoc.org/google.golang.org/cloud/storage
rc, err := storage.NewReader(ctx, "bucket", "object1")
if err != nil {
log.Fatal(err)
}
slurp, err := ioutil.ReadAll(rc)
rc.Close()
if err != nil {
log.Fatal(err)
}
Google Cloud Pub/Sub (Alpha)
Google Cloud Pub/Sub is in Alpha status. As a result, it might change in
backward-incompatible ways and is not recommended for production use. It is not
subject to any SLA or deprecation policy.
Google Cloud Pub/Sub (docs) allows you to connect
your services with reliable, many-to-many, asynchronous messaging hosted on Google's
infrastructure. Cloud Pub/Sub automatically scales as you need it and provides a foundation
for building your own robust, global services.
https://godoc.org/google.golang.org/cloud/pubsub
msgIDs, err := pubsub.Publish(ctx, "topic1", &pubsub.Message{
Data: []byte("hello world"),
})
if err != nil {
log.Println(err)
}
msgs, err := pubsub.Pull(ctx, "subscription1", 1)
if err != nil {
log.Println(err)
}
