Overview

This repository demonstrates how to manage the graceful termination with Cloud Run in Go and how to call the service to always keep one instance warm and thus to minimize the cold starts.

This code illustrates this article

Deployment

Build

To build the container, you have several solution

Cloud Build with Buildpack (Dockerfile is useless, you can delete it in this case)

# Update with your project ID
PROJECT_ID=<MY_PROKECT_ID>

cloud builds submit --pack image=gcr.io/${PROJECT_ID}/self-call-sigterm

Cloud Build with Dockerfile

# Update with your project ID
PROJECT_ID=<MY_PROKECT_ID>

gcloud builds submit -t gcr.io/${PROJECT_ID}/self-call-sigterm

Locally with docker

# Update with your project ID
PROJECT_ID=<MY_PROKECT_ID>

docker build -t gcr.io/${PROJECT_ID}/self-call-sigterm .
docker push gcr.io/${PROJECT_ID}/self-call-sigterm

Deployment

Simply deploy the service on Cloud Run

# Update with your project ID
PROJECT_ID=<MY_PROKECT_ID>

gcloud run deploy --platform=managed --region=us-central1 --image=gcr.io/${PROJECT_ID}/self-call-sigterm \
--allow-unauthenticated self-call-sigterm

And then call it to initialize.

curl $(gcloud run services describe --format="value(status.url)" self-call-sigterm)
