Cloud Run
​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.
You can deploy a Hello World Application simply by click on the Run on Google Cloud button below!
​​
​​
cd $HOMEgit clone https://github.com/saturnism/jvm-helloworld-by-examplecd jvm-helloworld-by-example/helloworld-springboot-tomcat
./mvnw package
Enable the Container Registry API so that you can push container images to Container Registry.
gcloud services enable containerregistry.googleapis.com
Use Jib to containerize the application:
PROJECT_ID=$(gcloud config get-value project)​./mvnw compile com.google.cloud.tools:jib-maven-plugin:2.4.0:build \-Dimage=gcr.io/${PROJECT_ID}/helloworld
Learn different ways to containerize a Java application in the Container Image section.
# To use Cloud Rungcloud services enable run.googleapis.com
PROJECT_ID=$(gcloud config get-value project)​gcloud run deploy helloworld \--region=us-central1 \--platform=managed \--allow-unauthenticated \--image=gcr.io/${PROJECT_ID}/helloworld
Once deployed, Cloud Run will display the HTTPs URL. You can also find the URL with the command line:
gcloud run services describe helloworld \--region=us-central1 \--platform=managed
You can curl the URL:
URL=$(gcloud run services describe helloworld \--region=us-central1 \--platform=managed \--format='value(status.address.url)')​curl ${URL}
By default, Cloud Run will deploy with the smallest 1CPU 256MB instance. You can specify a larger instance, and configure environment variables with the gcloud CLI:
PROJECT_ID=$(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
