Google Cloud Storage

PROJECT_ID=`gcloud config get-value project`

create a bucket

gsutil mb -c multi_regional gs://${BUCKET}

copy local folder "endpointslambda" into bucket

Google Cloud Functions

deploy a cloud function

gcloud functions deploy helloWorld \
  --stage-bucket qwiklabs-gcp-00-d68a427ec7ac-bucket \
  --trigger-topic hello_world \
  --runtime nodejs10

For the above there is a file in the current directory called index.js with the follwoing contents

* Background Cloud Function to be triggered by Pub/Sub.
* This function is exported by index.js, and executed when
* the trigger topic receives a message.
* @param {object} data The event payload.
* @param {object} context The event metadata.
exports.helloWorld = (data, context) => {
const pubSubMessage = data;
const name =
    ? Buffer.from(, 'base64').toString() : "Hello World";

console.log(`My Cloud Function: ${name}`);

Show the status of a cloud function

gcloud functions describe helloWorld

Read the logs of a cloud function

gcloud functions logs read helloWorld
