sandbox: add gvisor runsc-based sandbox

This creates a VM (running Container-Optimized OS) with configuration
such that it boots up and downloads/configures the runsc Docker
runtime, reloading the existing Docker daemon on the VM, and then
creates a new privileged Docker container with the host's
/var/run/docker.sock available to the container. From within that
container it's then possible for the new sandbox HTTP server to create
its own Docker containers running under gvisor (using docker run
--runtime=runsc).

This then adds a regional us-central1 load balancer and instance group
manager & instane template to run these VMs automatically across
us-central1. Then the play.golang.org frontend can hit that URL
(http://sandbox.play-sandbox-fwd.il4.us-central1.lb.golang-org.internal)

Fixes golang/go#25224
Updates golang/go#30439 (remove nacl)
Updates golang/go#33629 (this CL makes the playground support 2 versions)

playground

This subrepository holds the source for the Go playground: https://play.golang.org/

Building

# build the image
docker build -t playground .

Running

docker run --name=play --rm -p 8080:8080 golang/playground &
# run some Go code
cat /path/to/code.go | go run client.go | curl -s --upload-file - localhost:8080/compile

Deployment

Deployment Triggers

Playground releases automatically triggered when new Go repository tags are pushed to GitHub, or when master is pushed on the playground repository.

For details, see deploy/go_trigger.json, deploy/playground_trigger.json, and deploy/deploy.json.

After making changes to trigger configuration, update configuration by running the following Make target:

make update-cloudbuild-trigger

Deploy via Cloud Build

The Cloud Build configuration will always build and deploy with the latest supported release of Go.

gcloud builds submit --config deploy/deploy.json .

Deploy via gcloud app deploy

Building the playground Docker container takes more than the default 10 minute time limit of cloud build, so increase its timeout first (note, app/cloud_build_timeout is a global configuration value):

gcloud config set app/cloud_build_timeout 1200  # 20 mins

Alternatively, to avoid Cloud Build and build locally:

make docker
docker tag golang/playground:latest gcr.io/golang-org/playground:latest
docker push gcr.io/golang-org/playground:latest
gcloud --project=golang-org --account=you@google.com app deploy app.yaml --image-url=gcr.io/golang-org/playground:latest

Then:

gcloud --project=golang-org --account=you@google.com app deploy app.yaml
