1. Secure Data Ingestion to OCI Object Storage via Service Gateway

    Python

    To securely ingest data into OCI Object Storage via a Service Gateway in Pulumi, we will be following these steps:

    1. Set up a Virtual Cloud Network (VCN) in OCI to lay down the networking foundation.
    2. Create a Service Gateway within the VCN to allow secure, private access to OCI Object Storage.
    3. Define an Object Storage Bucket where the ingested data will reside.
    4. Configure necessary policies and rules to enable data flow through the Service Gateway into the Object Storage Bucket.

    We will use various OCI Pulumi resources to accomplish this:

    • oci.Core.Vcn: To create a Virtual Cloud Network (VCN) for setting up our network.
    • oci.Core.RouteTable: To create a route table for our VCN to direct traffic to the Service Gateway.
    • oci.Core.ServiceGateway: To create a Service Gateway that enables access to Object Storage service.
    • oci.ObjectStorage.Bucket: To define a bucket in OCI Object Storage to store ingested data.

    Below is the Pulumi program written in Python that sets up a secure data ingestion path to OCI Object Storage via a Service Gateway:

    import pulumi import pulumi_oci as oci # Replace these variables with your own unique names and settings compartment_id = 'ocid1.compartment.oc1..example_unique_id' # Replace with your Compartment's OCID vcn_cidr_block = '10.0.0.0/16' # Customize your VCN CIDR block # Create a Virtual Cloud Network (VCN) vcn = oci.core.Vcn("my-vcn", cidr_block=vcn_cidr_block, compartment_id=compartment_id, display_name="my-vcn") # Create a Route Table route_table = oci.core.RouteTable("my-route-table", compartment_id=compartment_id, vcn_id=vcn.id, display_name="my-route-table") # This is the Oracle Service for Object Storage object_storage_service = oci.core.Services("object-storage-service", service_name="Object Storage") # Create a Service Gateway service_gateway = oci.core.ServiceGateway("my-service-gateway", compartment_id=compartment_id, vcn_id=vcn.id, services=[object_storage_service.id], route_table_id=route_table.id, display_name="my-service-gateway") # Create an Object Storage Bucket bucket = oci.objectstorage.Bucket("my-bucket", compartment_id=compartment_id, namespace="mynamespace", # Replace with your Object Storage Namespace name="my-data-bucket") # Output the details of the bucket pulumi.export("bucket_name", bucket.name) pulumi.export("bucket_namespace", bucket.namespace) # This prints the Object Storage URL where data can be accessed # Assumes that the OCI Object Storage is publicly accessible pulumi.export("bucket_access_url", pulumi.Output.concat("https://objectstorage.", oci.get_region().region_key, ".oraclecloud.com/n/", bucket.namespace, "/b/", bucket.name, "/o/"))

    How this code works:

    1. We import the required Pulumi modules for Python.
    2. We create an instance of a VCN with a specified CIDR block.
    3. We create a route table that will be associated with the VCN.
    4. We query for the OCI service ID that corresponds to the Object Storage service because the Service Gateway requires this information to be set up.
    5. We create a Service Gateway that allows resources in our VCN to access the Object Storage service without traversing the public internet.
    6. We then create an Object Storage Bucket, which is where the ingested data will be stored.
    7. Lastly, we export the bucket name, namespace, and a constructed URL for accessing the bucket resources.

    This program lays the groundwork for a secure data flow from your private network in OCI to Object Storage through a Service Gateway. You should replace placeholder values with the actual values from your OCI account and infrastructure specifications. Additionally, you would typically set up appropriate policies and rules to control access according to your organizational requirements.
