internal/metrics: fix detection of GCE environment

appengine.IsAppEngine mistakenly returns false, as it relies on the app
being built with the appenginevm build constraint. This is not set,
as we're supplying our own Docker image.

The playground is always running either locally or on appengine. We can
rely on metadata.OnGCE being correct.

Other calls that are made to the appengine library either use the
metadata server or environment variables, and do not rely on a
constraint being set. They also panic if the metadata server is
unavailable.

For golang/go#44822

playground

Go Reference

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

Building

# build the image
docker build -t golang/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
