Cloud Run
Deploy a container to serverless environment using a single command.
Cloud Run is a fully managed container runtime environment, where you can deploy any HTTP serving container, and Cloud Run will automatically scale out the number of instances as needed, and scale down to zero when no one is using it.
Getting Started - Click to Deploy
You can deploy a Hello World Application simply by click on the Run on Google Cloud button below!
Getting Started - Manual Deployment
Clone
cd $HOME
git clone https://github.com/saturnism/jvm-helloworld-by-example
cd jvm-helloworld-by-example/helloworld-springboot-tomcat
Build
./mvnw package
Containerize
Enable API
Enable the Container Registry API so that you can push container images to Container Registry.
gcloud services enable containerregistry.googleapis.com
Jib
Use Jib to containerize the application:
PROJECT_ID=$(gcloud config get-value project)
./mvnw compile com.google.cloud.tools:jib-maven-plugin:2.4.0:build \
-Dimage=gcr.io/${PROJECT_ID}/helloworld
Deploy
Enable API
# To use Cloud Run
gcloud services enable run.googleapis.com
Deploy Container
PROJECT_ID=$(gcloud config get-value project)
gcloud run deploy helloworld \
--region=us-central1 \
--platform=managed \
--allow-unauthenticated \
--image=gcr.io/${PROJECT_ID}/helloworld
Connect
Once deployed, Cloud Run will display the HTTPs URL. You can also find the URL with the command line:
gcloud run services describe helloworld \
--region=us-central1 \
--platform=managed
You can curl
the URL:
URL=$(gcloud run services describe helloworld \
--region=us-central1 \
--platform=managed \
--format='value(status.address.url)')
curl ${URL}
Additional Configurations
By default, Cloud Run will deploy with the smallest 1CPU 256MB instance. You can specify a larger instance, and configure environment variables with the gcloud
CLI:
PROJECT_ID=$(gcloud config get-value project)
gcloud run deploy helloworld --platform=managed --allow-unauthenticated \
--cpu=2 --memory=512M --set-env-vars="SPRING_PROFILES_ACTIVE=prod" \
--image=gcr.io/${PROJECT_ID}/helloworld
