# Contributing
1. Sign one of the contributor license agreements below.
1. `go get golang.org/x/review/git-codereview` to install the code reviewing tool.
1. Get the cloud package by running `go get -d google.golang.org/cloud`.
1. If you have already checked out the source, make sure that the remote git
origin is https://code.googlesource.com/gocloud:
git remote set-url origin https://code.googlesource.com/gocloud
1. Make changes and create a change by running `git codereview change <name>`,
provide a command message, and use `git codereview mail` to create a Gerrit CL.
1. Keep amending to the change and mail as your recieve feedback.
## Integration Tests
Additional to the unit tests, you may run the integration test suite.
To run the integrations tests, creating and configuration of a project in the
Google Developers Console is required. Once you create a project, set the
following environment variables to be able to run the against the actual APIs.
- **GCLOUD_TESTS_GOLANG_PROJECT_ID**: Developers Console project's ID (e.g. bamboo-shift-455)
- **GCLOUD_TESTS_GOLANG_KEY**: The path to the JSON key file.
Create a storage bucket with the same name as the project id set in **GCLOUD_TESTS_GOLANG_PROJECT_ID**.
The storage integration test will create and delete some objects in this bucket.
Install the [gcloud command-line tool][gcloudcli] to your machine and use it
to create the indexes used in the datastore integration tests with indexes
found in `datastore/testdata/index.yaml`:
From the project's root directory:
``` sh
# Install the app component
$ gcloud components update app
# Set the default project in your env
$ gcloud config set project $GCLOUD_TESTS_GOLANG_PROJECT_ID
# Authenticate the gcloud tool with your account
$ gcloud auth login
# Create the indexes
$ gcloud preview datastore create-indexes datastore/testdata/index.yaml
```
You can run the integration tests by running:
``` sh
$ go test -v -tags=integration google.golang.org/cloud/...
```

# Google Cloud for Go
[![Build Status](https://travis-ci.org/GoogleCloudPlatform/gcloud-golang.svg?branch=master)](https://travis-ci.org/GoogleCloudPlatform/gcloud-golang)
**NOTE:** These packages are experimental, and may occasionally make
backwards-incompatible changes.
**NOTE:** Github repo is a mirror of [https://code.googlesource.com/gocloud](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
``` go
import "google.golang.org/cloud"
```
Documentation and examples are available at
[https://godoc.org/google.golang.org/cloud](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](https://godoc.org/golang.org/x/oauth2)
for examples on using oauth2 with the Cloud package.
## Google Cloud Datastore
[Google Cloud Datastore][cloud-datastore] ([docs][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][cloud-datastore-activation] to use the Google
Cloud Datastore API with your project.
[https://godoc.org/google.golang.org/cloud/datastore](https://godoc.org/google.golang.org/cloud/datastore)
```go
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][cloud-storage] ([docs][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](https://godoc.org/google.golang.org/cloud/storage)
```go
// Read the object1 from bucket.
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][cloud-pubsub] ([docs][cloud-pubsub-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](https://godoc.org/google.golang.org/cloud/pubsub)
```go
// Publish "hello world" on topic1.
msgIDs, err := pubsub.Publish(ctx, "topic1", &pubsub.Message{
Data: []byte("hello world"),
})
if err != nil {
log.Println(err)
}
// Pull messages via subscription1.
msgs, err := pubsub.Pull(ctx, "subscription1", 1)
if err != nil {
log.Println(err)
}
```
