1. Accessible IP for OCI Data Flow Streams


    To create an accessible IP for Oracle Cloud Infrastructure (OCI) Data Flow Streams, we'll use Pulumi's OCI provider to set up the necessary resources. We will need to create a Stream resource and set up networking entities that grant access to the stream. Note that we will be using a public IP for simplicity, but in a real-world scenario, you may want to use a private IP and Private Endpoint for added security, based on your specific requirements.

    Below you'll find a Pulumi program written in Python that will:

    1. Create an OCI stream, which is the fundamental entity for OCI Streaming Service.
    2. Set up a Public IP, which could be utilized to access the OCI Stream data.

    Do note that actual network access and security will depend on additional networking resources such as Security Lists, Network Security Groups, or specific Route Tables within your Virtual Cloud Network (VCN), which are not covered in this basic setup. You can follow the OCI documentation to configure these according to your needs.

    Let's go through the program step by step:

    import pulumi import pulumi_oci as oci # Replace the following variables with your own information compartment_id = 'ocid1.compartment.oc1..xxxxxx' # OCI Compartment OCID # Create an OCI streaming service stream stream = oci.streaming.Stream("MyStream", compartment_id=compartment_id, name="DataStream", partitions=1, # The number of partitions in the stream retention_in_hours=24, # The retention period of your messages in hours stream_pool_id='ocid1.streampool.oc1..xxxxxx', # OCI Stream Pool OCID ) # To make the stream accessible, let's create a Public IP # Public IP can be used in conjunction with your network configuration to allow access to the streams. # Ensure you have proper network security configurations to protect your streams when using a public IP. public_ip = oci.core.PublicIp("MyPublicIp", compartment_id=compartment_id, lifetime="RESERVED", # You can choose between 'RESERVED' or 'EPHEMERAL' display_name="MyStreamPublicIP", ) # Optional: You might want to export some of these details for easier access or for integration with other systems. pulumi.export('stream_id', stream.id) pulumi.export('stream_messages_endpoint', stream.messages_endpoint) pulumi.export('public_ip_address', public_ip.ip_address)

    This program initializes an OCI Stream within a specified compartment and creates a reserved Public IP which we associate with this service. This doesn't actually bind the Public IP to the stream — additional network configuration is needed outside of the scope of this program.

    Here's what the program does in detail:

    1. The oci.streaming.Stream resource creates a stream that you can use to send and receive messages. The partitions parameter specifies the throughput of the stream, and retention_in_hours specifies how long messages will be retained.

    2. The oci.core.PublicIp resource creates a Public IP which reserves an IP address within OCI. The lifetime parameter determines whether the IP address is ephemeral (temporary) or reserved (persistent).

    3. The program exports a few key details about the resources created: the stream's ID and messages endpoint, along with the public IP address. These exports make the program's outputs easily accessible outside of Pulumi and can be useful for integration or access purposes.

    Remember, you typically need to provide more detailed network configuration to ensure controlled access, security, and connectivity to the stream within OCI. This can include setting up route tables, security lists, or network security groups within your existing VCN.

    Please review and adjust security and network settings according to your organization's policies and best practices before using this in a production environment.
