all: fix build timeouts for std dependent snippets

This change addresses two issues that were causing the first build of a
snippet to be unusually slow.

One is to build the standard library with faketime, and CGO_ENABLED=0 in
our final container, which is more similar to our actual build
environment. This fixes staleness issues from std.

Another is to pre-vet std with --tags=faketime. The first vet of a
snippet that contained a significant std package such as net/http would
take 5-6 seconds, and frequently longer than our maxBuildTime of 10s.

Finally, execute vet with the correct tags when a user is vetting their
snippet.

Fixes 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.yaml, deploy/playground_trigger.yaml, and deploy/deploy.json.

Changes to the trigger configuration can be made to the YAML files, or in the GCP UI, which should be kept in sync using the push-cloudbuild-trigger and pull-cloudbuild-trigger make targets.

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
