Eventarc Samples

This directory contains samples for creating Cloud Run services that listens to events from Eventarc.

Samples

Sample	Description	Deploy
Eventarc - Pub/Sub	Listen to Pub/Sub events
Eventarc - Audit – Storage	Listen to Audit Log events from Cloud Storage
Eventarc - Generic	Listen to a generic event from Eventarc

Setup

1. Set up for Cloud Run development

2. Clone this repository:

   git clone https://github.com/GoogleCloudPlatform/java-docs-samples.git
   

3. In the samples's pom.xml, update the image field for the jib-maven-plugin with your Google Cloud Project Id:

   <plugin>
     <groupId>com.google.cloud.tools</groupId>
     <artifactId>jib-maven-plugin</artifactId>
     <version>2.0.0</version>
     <configuration>
       <to>
         <image>gcr.io/PROJECT_ID/SAMPLE_NAME</image>
       </to>
     </configuration>
   </plugin>

How to run a sample locally

1. Build the sample container using Jib:

   mvn compile jib:dockerBuild

2. Run containers locally by replacing PROJECT_ID and SAMPLE_NAME with your values.

   With the built container:

   PORT=8080 && docker run --rm -p 9090:${PORT} -e PORT=${PORT} gcr.io/PROJECT_ID/SAMPLE_NAME

   Injecting your service account key for access to GCP services:

   PORT=8080 && docker run \
      -p 9090:${PORT} \
      -e PORT=${PORT} \
      -e K_SERVICE=dev \
      -e K_CONFIGURATION=dev \
      -e K_REVISION=dev-00001 \
      -e GOOGLE_APPLICATION_CREDENTIALS=/tmp/keys/[FILE_NAME].json \
      -v $GOOGLE_APPLICATION_CREDENTIALS:/tmp/keys/[FILE_NAME].json:ro \
       gcr.io/PROJECT_ID/SAMPLE_NAME

   • Use the --volume (-v) flag to inject the credential file into the container (assumes you have already set your GOOGLE_APPLICATION_CREDENTIALS environment variable on your machine)

   • Use the --environment (-e) flag to set the GOOGLE_APPLICATION_CREDENTIALS variable inside the container

3. Open http://localhost:9090 in your browser.

Deploying

1. Build the sample container using Jib:

   mvn compile jib:build
   

   Note: Using the image tag gcr.io/PROJECT_ID/SAMPLE_NAME automatically pushes the image to Google Container Registry.

2. Deploy to Cloud Run by replacing PROJECT_ID and SAMPLE_NAME with your values:

   gcloud run deploy --image gcr.io/PROJECT_ID/SAMPLE_NAME
