Cloud Functions
Deploy a simple HTTP function.
​Cloud Function is a scalable, pay as you go, Functions-as-a-Service (FaaS).
Spring Cloud Functions has pre-GA support for Cloud Functions for Java 11. See Spring Cloud Functions Reference Documentation for more details.
This guide currently uses a non-Spring example for Cloud Functions.
cd $HOMEgit clone https://github.com/GoogleCloudPlatform/java-docs-samplescd java-docs-samples/functions/helloworld/helloworld
mvn package
mvn function:run​# In a different tab, trigger the function:curl localhost:8080
gcloud services enable cloudfunctions.googleapis.com
gcloud functions deploy helloworld --trigger-http \--runtime=java11 \--entry-point=functions.HelloWorld \--allow-unauthenticated
Once a HTTP function is deployed, you can connect to it using curl. You can also find the URL:
gcloud functions describe helloworld --format='value(httpsTrigger.url)'
Trigger the function with curl:
URL=$(gcloud functions describe helloworld --format='value(httpsTrigger.url)')​curl ${URL}
Alternatively, you can also use gcloud:
gcloud functions call helloworld
By default, Cloud Functions will deploy to the smallest 256MB instance. You can specify a larger instance and configure environment variables with the gcloud CLI:
gcloud functions deploy helloworld --trigger-http \--runtime=java11 \--memory=512M--entry-point=functions.HelloWorld \--allow-unauthenticated
