Cross Project Services for Vertex AI

[Mouzma]

Can we use cross-project services like BigQuery, Artifact Registry, Container Registry, Storage, KMS, etc. with Vertex AI? I use Vertex from Console, so it browses the current project buckets whenever I specify a bucket, etc. I cannot see cross-project resources.

Hi @Mouzma, 

You can access multiple GCP services through the use of Service Accounts. You need to create a service account in the project where the specific service/s that you need resides, then assign it with the appropriate IAM permission. You can use this service account to access the service/s from Vertex AI.

Here are some usable resources for your reference.

• Vertex AI access control with IAM 
• Manage access to projects, folders, and organizations
• Granting service accounts access to your projects
• Best practices for using service accounts

I've also found a StackOverflow post that relates to your use case.

I hope this helps.
