playground: simplify latest go version logic

This changes the build process to use a newly-added latestgo command for
determining the latest version of Go. This simplifies the Cloud Build
deploy.json significantly.

latestgo fetches the latest supported Go releases from maintner,
returning the first one. The maintner API always returns at least 2
releases on success, with the first result being the latest supported Go
release.

Updates golang/go#32606

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 -d -p 8080:8080 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 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
