It seems you are looking for a way to interact with Google Cloud Storage (GCS) using a protocol similar to Amazon S3. Google Cloud Storage provides a compatibility mode called “Cloud Storage interoperability” that allows you to use tools and libraries designed for Amazon S3 to access GCS. This feature is helpful if you have existing S3-compatible applications or tools and want to transition to Google Cloud.

To interact with Google Cloud Storage using S3-compatible tools or libraries, you’ll need to configure your S3 client with the appropriate settings. Here are some key points:

1. Endpoint: Configure your S3 client to use the GCS S3-compatible endpoint. The endpoint typically follows this format: https://storage.googleapis.com.

2. Access and Secret Keys: You can use your Google Cloud credentials (Service Account JSON key file) to authenticate. However, you need to configure your S3 client with the appropriate access key and secret key fields, even though Google Cloud uses different authentication methods. The access key is typically the service account email, and the secret key is the JSON key file’s private key.

3. Bucket Names: In GCS, bucket names must be globally unique, whereas in S3, they only need to be unique within the S3 namespace. Adjust your bucket naming accordingly.

4. Permissions: Ensure that your Google Cloud Service Account has the necessary permissions to access GCS buckets and objects. You can configure IAM roles and permissions within Google Cloud.

By configuring your S3-compatible client with these settings, you should be able to interact with Google Cloud Storage as if it were Amazon S3, allowing you to use S3-compatible tools and libraries for your GCS storage needs.
