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

Set up for Cloud Run development

Clone this repository:

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

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

Build the sample container using Jib:
```
mvn compile jib:dockerBuild
```
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
Open http://localhost:9090 in your browser.

Deploying

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.
Deploy to Cloud Run by replacing PROJECT_ID and SAMPLE_NAME with your values:
```
gcloud run deploy --image gcr.io/PROJECT_ID/SAMPLE_NAME
```
