playground: slurp binary to memory in gvisor mode Slurp the binary to memory before POSTing it. This simplifies retries a bit (doesn't need to re-open the file) and sets a Content-Length header, and checks the file size early, rather than having the backend complain. None of this should matter for correctness (and unnecessarily uses more memory than before), but we're sometimes seeing timeout errors followed by this frontend returning (and caching!) an empty response where the backend never sees a binary arrive, so this is somewhat a shot in the dark for now. Something's up with our internal load balancer, perhaps. Still debugging. Also update/add some comments.

This subrepository holds the source for the Go playground: https://play.golang.org/
# build the image docker build -t playground .
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
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:
The Cloud Build configuration will always build and deploy with the latest supported release of Go.
gcloud builds submit --config deploy/deploy.json .
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 --firstname.lastname@example.org app deploy app.yaml --image-url=gcr.io/golang-org/playground:latest
gcloud --project=golang-org --email@example.com app deploy app.yaml
