google adk deploying to gcp cloud run

Image
We can deploy ADK agent to google cloud with adk command line. This would be available when we install adk module as part of your deployment requirements. To deploy your applications run the following command and if you trying to deploy sample app when you're in the root folder $AGENT_PATH=.  $SERVICE_NAME would be the name for your cloud run.  adk deploy cloud_run \ --project=$GOOGLE_CLOUD_PROJECT \ --region=$GOOGLE_CLOUD_LOCATION \ --service_name=$SERVICE_NAME \ --app_name=$APP_NAME \ --with_ui \ $AGENT_PATH If you do not have an existing container registry, it will prompt if you want to be created. You will be prompted if you would allowed anonymous invocations.  And the output would be something like this:- After you have successfully deploy it, your agentic AI can be tested via the deployed URL.  If you click on the cloud run endpoint, this would appear. And you can type away.

Using Cloudrun to update your Vertex AI RAG

Image
In this example, we are going to use Google cloud run to update corpus Vertex AI RAG. So when we have a new document, we load it up into Cloud storage. This generates an event for Cloud Run and update RAG.  To setup our Cloud run with event trigger. We will give it a name and then configure the target resource name. As you can see we are using "tgoogle.cloud.storage.object.v1.finalized" which gets fired when we create a new object, or overwrite an existing object, and Cloud Storage creates a new generation of that object. This is code in our cloud run. import functions_framework import os from google.cloud import aiplatform from vertexai.preview import rag import vertexai # Configuration from Environment Variables PROJECT_ID = os.environ.get( "PROJECT_ID" ) LOCATION = os.environ.get( "LOCATION" , "us-central1" ) RAG_CORPUS_ID = os.environ.get( "RAG_CORPUS_ID" ) vertexai.init(project=PROJECT_ID, location=LOCATION) # Triggered by a...

private endpoint with multiple vnet how do you connect

Image
When we setup multiple VNET and peer them, let's say we have marketing VNET and research VNET. then we created a storage account and setup private link in research VNET. At this point, VM trying to resolve our storage account in marketing vnet will get a public ip. How do we configure to ensure this VM in marketing would be able internal IP?  All we need to do is go to the Private dns zone that we have created and then add a " Virtual Network link " and we choose "marketing" vnet target network. And then in the VM that we have created in marketing VNET, you can see that we are resolving to a local ip address instead of public.  And then if we look at the subnet. there's no IP that has been taken up.
