all: support Go 1.16 in the Go Playground

This makes a number of changes in order to support modules being on by
default in Go 1.16.

- Change default Go version in Dockerfile to go1.16
- Change default Go version in sandbox/Dockerfile to go1.16
- Build playground web server with GO_VERSION instead of
GO_BOOTSTRAP_VERSION (for golang/go#40319)
- Drop code related to non-module codepaths. This should keep us
future-proof for later versions of Go.

This works for me testing locally with gVisor's runsc.

Fixes golang/go#44389
Fixes golang/go#40319

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
