Public IP Addressing for OCI Data Catalog

Question

Pulumi · Accepted Answer

To configure Public IP Addressing for an OCI Data Catalog, you need to work with several Oracle Cloud Infrastructure (OCI) resources. The main resource of interest for public IP addressing in OCI is the `oci.Core.PublicIp` resource. This resource allows you to create and manage public IP addresses, which can be used to create publicly accessible endpoints for your resources on Oracle Cloud.

Here’s a breakdown of what we will do in the Pulumi program:

1. Provision a Public IP Address using `oci.Core.PublicIp`.
2. Optionally, if needed, assign the provisioned public IP to other resources such as a compute instance or a load balancer that would be part of an OCI Data Catalog service deployment.

Before you start, make sure you have the OCI Pulumi provider configured and that you’re authenticated with the necessary permissions to create resources within your compartment.

Below is a Pulumi program written in Python that provisions a public IP address in OCI, which could be used to expose your OCI Data Catalog:

```python
import pulumi
import pulumi_oci as oci

# Initialize a new Public IP Address resource
public_ip = oci.core.PublicIp("myPublicIp",
    # Specify the compartment where the Public Ip will be created
    compartment_id=oci.config.require("compartment"),
    # Provide a display name for clarity in the OCI console
    display_name="MyDataCatalogPublicIP",
    # Specify the lifetime of the Public IP. Setting 'RESERVED' makes it permanent until it's manually deleted.
    lifetime="RESERVED",
    # Allocate the Public IP from a specific Public IP pool if required, otherwise it will be allocated from the regional pool
    # public_ip_pool_id=None
)

# Export the Assigned IP Address so you can use it later, e.g., to point a domain name to it
pulumi.export("public_ip_address", public_ip.ip_address)
```

This code sample uses the `oci.Core.PublicIp` class from the Pulumi OCI provider to create a reserved public IP address. You can customize the `compartment_id` and `display_name` to suit your environment. Once a public IP is created, it can be assigned to other OCI resources, such as a load balancer or a compute instance serving your data catalog's front end.

The `pulumi.export` line outputs the provisioned IP address so that you can use it outside Pulumi, for instance, to configure DNS.

Please ensure that you replace `oci.config.require("compartment")` with the actual Compartment ID where you want to create the Public IP resource within your OCI account. You need to have a `Pulumi.yaml` configuration file with your compartment ID specified or you can set it directly in your program.

This program, once executed, will give you a static public IP address which you can then use to set up your networking and access control rules to expose the OCI Data Catalog or any service associated with it to the public internet in a controlled way.
