# Google Cloud Client Libraries for Go
[![GoDoc](https://godoc.org/cloud.google.com/go?status.svg)](https://godoc.org/cloud.google.com/go)
Go packages for [Google Cloud Platform](https://cloud.google.com) services.
``` go
import "cloud.google.com/go"
```
To install the packages on your system, *do not clone the repo*. Instead use
```
$ go get -u cloud.google.com/go/...
```
**NOTE:** Some of these packages are under development, and may occasionally
make backwards-incompatible changes.
**NOTE:** Github repo is a mirror of [https://code.googlesource.com/gocloud](https://code.googlesource.com/gocloud).

## News
_7 August 2018_
As of November 1, the code in the repo will no longer support Go versions 1.8
and earlier. No one other than AppEngine users should be on those old versions,
and AppEngine
[Standard](https://groups.google.com/forum/#!topic/google-appengine-go/e7oPNomd7ak)
and
[Flex](https://groups.google.com/forum/#!topic/google-appengine-go/wHsYtxvEbXI)
will stop supporting new deployments with those versions on that date.
Changes have been moved to [CHANGES](https://github.com/GoogleCloudPlatform/google-cloud-go/blob/master/CHANGES.md).

> **Alpha status**: the API is still being actively developed. As a
> result, it might change in backward-incompatible ways and is not recommended
> for production use.
>
> **Beta status**: the API is largely complete, but still has outstanding
> features and bugs to be addressed. There may be minor backwards-incompatible
> changes where necessary.
>
> **Stable status**: the API is mature and ready for production use. We will
> continue addressing bugs and feature requests.

Visit or join the
[google-api-go-announce group](https://groups.google.com/forum/#!forum/google-api-go-announce)
for updates on these packages.
## Go Versions Supported
We support the two most recent major versions of Go. If Google App Engine uses
an older version, we support that as well.
## Authorization
By default, each API will use [Google Application Default Credentials][default-creds]
for authorization credentials used in calling the API endpoints. This will allow your
application to run in many environments without requiring explicit configuration.
[snip]:# (auth)
```go
client, err := storage.NewClient(ctx)
```
To authorize using a
[JSON key file](https://cloud.google.com/iam/docs/managing-service-account-keys),
pass
[`option.WithCredentialsFile`](https://godoc.org/google.golang.org/api/option#WithCredentialsFile)
to the `NewClient` function of the desired package. For example:
[snip]:# (auth-JSON)
```go
client, err := storage.NewClient(ctx, option.WithCredentialsFile("path/to/keyfile.json"))
```
You can exert more control over authorization by using the
[`golang.org/x/oauth2`](https://godoc.org/golang.org/x/oauth2) package to
create an `oauth2.TokenSource`. Then pass
[`option.WithTokenSource`](https://godoc.org/google.golang.org/api/option#WithTokenSource)
to the `NewClient` function:
[snip]:# (auth-ts)
```go
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
```

type Post struct {
Title string
Body string `datastore:",noindex"`
PublishedAt time.Time
}
keys := []*datastore.Key{
datastore.NameKey("Post", "post1", nil),
datastore.NameKey("Post", "post2", nil),
}
posts := []*Post{
{Title: "Post 1", Body: "...", PublishedAt: time.Now()},
{Title: "Post 2", Body: "...", PublishedAt: time.Now()},
}
if _, err := client.PutMulti(ctx, keys, posts); err != nil {

if err != nil {
log.Fatal(err)
}
```
[snip]:# (storage-2)
```go
// Read the object1 from bucket.
rc, err := client.Bucket("bucket").Object("object1").NewReader(ctx)
if err != nil {
log.Fatal(err)
}
defer rc.Close()
body, err := ioutil.ReadAll(rc)
if err != nil {
log.Fatal(err)
}
```

- [About Cloud Pubsub][cloud-pubsub]
- [API documentation][cloud-pubsub-docs]
- [Go client documentation](https://godoc.org/cloud.google.com/go/pubsub)
- [Complete sample programs](https://github.com/GoogleCloudPlatform/golang-samples/tree/master/pubsub)
### Example Usage
First create a `pubsub.Client` to use throughout your application:
[snip]:# (pubsub-1)
```go
client, err := pubsub.NewClient(ctx, "project-id")
if err != nil {
log.Fatal(err)
}
```
Then use the client to publish and subscribe:
[snip]:# (pubsub-2)
```go
// Publish "hello world" on topic1.
topic := client.Topic("topic1")
res := topic.Publish(ctx, &pubsub.Message{
Data: []byte("hello world"),
})
// The publish happens asynchronously.
// Later, you can get the result from res:
...
msgID, err := res.Get(ctx)
if err != nil {
log.Fatal(err)
}
// Use a callback to receive messages via subscription1.
sub := client.Subscription("subscription1")
err = sub.Receive(ctx, func(ctx context.Context, m *pubsub.Message) {
fmt.Println(m.Data)
m.Ack() // Acknowledge that we've consumed the message.
})
if err != nil {
log.Println(err)
}
```
## BigQuery [![GoDoc](https://godoc.org/cloud.google.com/go/bigquery?status.svg)](https://godoc.org/cloud.google.com/go/bigquery)
- [About BigQuery][cloud-bigquery]
- [API documentation][cloud-bigquery-docs]
- [Go client documentation][cloud-bigquery-ref]
- [Complete sample programs](https://github.com/GoogleCloudPlatform/golang-samples/tree/master/bigquery)
### Example Usage
First create a `bigquery.Client` to use throughout your application:
[snip]:# (bq-1)
```go
c, err := bigquery.NewClient(ctx, "my-project-ID")
if err != nil {
// TODO: Handle error.
}
```
Then use that client to interact with the API:
[snip]:# (bq-2)
```go
// Construct a query.
q := c.Query(`
SELECT year, SUM(number)
FROM [bigquery-public-data:usa_names.usa_1910_2013]
WHERE name = "William"
GROUP BY year
ORDER BY year
`)
// Execute the query.
it, err := q.Read(ctx)
if err != nil {
// TODO: Handle error.
}
// Iterate through the results.
for {
var values []bigquery.Value
err := it.Next(&values)
if err == iterator.Done {
break
}
if err != nil {
// TODO: Handle error.
}
fmt.Println(values)
}
```

[snip]:# (logging-1)
```go
ctx := context.Background()
client, err := logging.NewClient(ctx, "my-project")
if err != nil {
// TODO: Handle error.
}
```
Usually, you'll want to add log entries to a buffer to be periodically flushed
(automatically and asynchronously) to the Stackdriver Logging service.
[snip]:# (logging-2)
```go
logger := client.Logger("my-log")
logger.Log(logging.Entry{Payload: "something happened!"})
```
Close your client before your program exits, to flush any buffered log entries.
[snip]:# (logging-3)
```go
err = client.Close()
if err != nil {
// TODO: Handle error.
}
```

[]interface{}{"alice", "a@example.com"})})
if err != nil {
log.Fatal(err)
}

spanner.Key{"alice"}, []string{"email"})
if err != nil {
log.Fatal(err)
}

//
// In Go 1.2, the format of the data changed so that there is a single LineTable
// for the entire program, shared by all Funcs, and there are no absolute line
// numbers, just line numbers within specific files.

// detail of the package; callers should use the methods on Table instead.

# Compose on Kubernetes
[![CircleCI](https://circleci.com/gh/docker/compose-on-kubernetes/tree/master.svg?style=svg)](https://circleci.com/gh/docker/compose-on-kubernetes/tree/master)
Compose on Kubernetes allows you to deploy Docker Compose files onto a
Kubernetes cluster.
# Table of contents
- [Get started](#get-started)
- [Developing Compose on Kubernetes](#developing-compose-on-kubernetes)
More documentation can be found in the [docs/](./docs) directory. This includes:
- [Architecture](./docs/architecture.md)
- [Mapping of stack to Kubernetes objects](./docs/mapping.md)
- [Compatibility matrix](./docs/compatibility.md)
# Get started
Compose on Kubernetes comes installed on
[Docker Desktop](https://www.docker.com/products/docker-desktop) and
[Docker Enterprise](https://www.docker.com/products/docker-enterprise).
On Docker Desktop you will need to activate Kubernetes in the settings to use
Compose on Kubernetes.
## Check that Compose on Kubernetes is installed
You can check that Compose on Kubernetes is installed by checking for the
availability of the API using the command:
```console
$ kubectl api-versions | grep compose
compose.docker.com/v1beta1
compose.docker.com/v1beta2
```
## Deploy a stack
To deploy a stack, you can use the Docker CLI:
```console
$ cat docker-compose.yml
version: '3.3'
services:
db:
build: db
image: dockersamples/k8s-wordsmith-db
words:
build: words
image: dockersamples/k8s-wordsmith-api
deploy:
replicas: 5
web:
build: web
image: dockersamples/k8s-wordsmith-web
ports:
- "33000:80"
$ docker stack deploy --orchestrator=kubernetes -c docker-compose.yml hellokube
```
# Developing Compose on Kubernetes
See the [contributing](./CONTRIBUTING.md) guides for how to contribute code.
## Pre-requisites
- `make`
- [Docker Desktop](https://www.docker.com/products/docker-desktop) (Mac or Windows) with engine version 18.09 or later
- Enable Buildkit by setting `DOCKER_BUILDKIT=1` in your environment
- Enable Kubernetes in Docker Desktop settings
### For live debugging
- Debugger capable of remote debugging with Delve API version 2
- Goland run-configs are pre-configured
## Debug quick start
### Debug install
To build and install a debug version of Compose on Kubernetes onto Docker
Desktop, you can use the following command:
```console
$ make -f debug.Makefile install-debug-images
```
This command:
- Builds the images with debug symbols
- Runs the debug installer:
- Installs debug versions of API server and Compose controller in the `docker` namespace
- Creates two debugging _LoadBalancer_ services (unused in this mode)
You can verify that Compose on Kubernetes is running with `kubectl` as follows:
```console
$ kubectl get all -n docker
NAME READY STATUS RESTARTS AGE
pod/compose-7c4dfcff76-jgwst 1/1 Running 0 59s
pod/compose-api-759f8dbb4b-2z5n2 2/2 Running 0 59s
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/compose-api ClusterIP 10.98.42.151 <none> 443/TCP 59s
service/compose-api-server-remote-debug LoadBalancer 10.101.198.179 localhost 40001:31693/TCP 59s
service/compose-controller-remote-debug LoadBalancer 10.101.158.160 localhost 40000:31167/TCP 59s
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
deployment.apps/compose 1 1 1 1 59s
deployment.apps/compose-api 1 1 1 1 59s
NAME DESIRED CURRENT READY AGE
replicaset.apps/compose-7c4dfcff76 1 1 1 59s
replicaset.apps/compose-api-759f8dbb4b 1 1 1 59s
```
If you describe one of the deployments, you should see `*-debug:latest` in the
image name.
### Live debugging install
To build and install a live debugging version of Compose on Kubernetes onto
Docker Desktop, you can use the following command:
```console
$ make -f debug.Makefile install-live-debug-images
```
This command:
- Builds the images with debug symbols
- Sets the image entrypoint to run a [Delve server](https://github.com/derekparker/delve)
- Runs the debug installer
- Installs debug version of API server and Compose controller in the `docker` namespace
- Creates two debugging _LoadBalancer_ services
- `localhost:40000`: Compose controller
- `localhost:40001`: API server
- The API server and Compose controller only start once a debugger is attached
To attach a debugger you have multiple options:
- Use [GoLand](https://www.jetbrains.com/go/): configuration can be found in `.idea` of the repository
- Select the `Debug all` config, setup breakpoints and start the debugger
- Set your Delve compatible debugger to point to use `locahost:40000` and `localhost:40001`
- Using a terminal: `dlv connect localhost:40000` then type `continue` and hit enter
To verify that the components are installed, you can use the following command:
```console
$ kubectl get all -n docker
```
To verify that the API server has started, ensure that it has started logging:
```console
$ kubectl logs -f -n docker deployment.apps/compose-api compose
API server listening at: [::]:40000
ERROR: logging before flag.Parse: I1207 15:25:13.760739 11 plugins.go:158] Loaded 2 mutating admission controller(s) successfully in the following order: NamespaceLifecycle,MutatingAdmissionWebhook.
ERROR: logging before flag.Parse: I1207 15:25:13.763211 11 plugins.go:161] Loaded 1 validating admission controller(s) successfully in the following order: ValidatingAdmissionWebhook.

ERROR: logging before flag.Parse: I1207 15:25:13.998154 11 serve.go:116] Serving securely on [::]:9443
```
To verify that the Compose controller has started, ensure that it is logging:
```console
kubectl logs -f -n docker deployment.apps/compose
API server listening at: [::]:40000
Version: v0.4.16-dirty
Git commit: b2e3a6b-dirty
OS/Arch: linux/amd64
Built: Fri Dec 7 15:18:13 2018
time="2018-12-07T15:25:19Z" level=info msg="Controller ready"
```
## Reinstall default
To reinstall the default Compose on Kubernetes on Docker Desktop, simply restart
your Kubernetes cluster. You can do this by deactivating and then reactivating
Kubernetes or by restarting Docker Desktop.
See the [contributing](./CONTRIBUTING.md) and [debugging](./DEBUGGING.md) guides.

# OAuth2 for Go
[![Build Status](https://travis-ci.org/golang/oauth2.svg?branch=master)](https://travis-ci.org/golang/oauth2)
[![GoDoc](https://godoc.org/golang.org/x/oauth2?status.svg)](https://godoc.org/golang.org/x/oauth2)
oauth2 package contains a client implementation for OAuth 2.0 spec.
## Installation
~~~~
go get golang.org/x/oauth2
~~~~
Or you can manually git clone the repository to
`$(go env GOPATH)/src/golang.org/x/oauth2`.
See godoc for further documentation and examples.
* [godoc.org/golang.org/x/oauth2](http://godoc.org/golang.org/x/oauth2)
* [godoc.org/golang.org/x/oauth2/google](http://godoc.org/golang.org/x/oauth2/google)
## App Engine
In change 96e89be (March 2015), we removed the `oauth2.Context2` type in favor
of the [`context.Context`](https://golang.org/x/net/context#Context) type from
the `golang.org/x/net/context` package
This means it's no longer possible to use the "Classic App Engine"
`appengine.Context` type with the `oauth2` package. (You're using
Classic App Engine if you import the package `"appengine"`.)
To work around this, you may use the new `"google.golang.org/appengine"`
package. This package has almost the same API as the `"appengine"` package,
but it can be fetched with `go get` and used on "Managed VMs" and well as
Classic App Engine.
See the [new `appengine` package's readme](https://github.com/golang/appengine#updating-a-go-app-engine-app)
for information on updating your app.
If you don't want to update your entire app to use the new App Engine packages,
you may use both sets of packages in parallel, using only the new packages
with the `oauth2` package.
```go
import (
"golang.org/x/net/context"
"golang.org/x/oauth2"
"golang.org/x/oauth2/google"
newappengine "google.golang.org/appengine"
newurlfetch "google.golang.org/appengine/urlfetch"
"appengine"
)
func handler(w http.ResponseWriter, r *http.Request) {
var c appengine.Context = appengine.NewContext(r)
c.Infof("Logging a message with the old package")
var ctx context.Context = newappengine.NewContext(r)
client := &http.Client{
Transport: &oauth2.Transport{
Source: google.AppEngineTokenSource(ctx, "scope"),
Base: &newurlfetch.Transport{Context: ctx},
},
}
client.Get("...")
}
```
