Description

New pages

  • cloud/cloud-metadata.mdx — Single source of truth for all Console-exposed metadata fields: IAM role ARN, PrivateLink Principal, and egress public IPs. Includes per-field descriptions, example values, an AWS/GCP/Azure comparison table, and a Console screenshot showing the ConnectionCloud Meta tab navigation.
  • cloud/iam-role-assume.mdx — End-to-end cross-account S3 setup guide. Maps the IAM role ARN from Cloud metadata to the IAM trust policy. Includes trust policy JSON template, SQL examples for Redshift/Snowflake/Iceberg connectors, verification steps, and a common-errors table.

Updated pages

  • cloud/privatelink-overview.mdx — Adds an "Accessing PrivateLink in the Console" section documenting the ConnectionPrivateLink tab navigation, and a tip referencing the PrivateLink Principal from Cloud metadata when setting up allowed principals on an AWS endpoint service.
  • cloud/create-a-connection.mdx — Updates PrivateLink creation and deletion steps to reflect the correct Connection sidebar navigation with PrivateLink tab.
  • docs.json — Registers both new pages under Cloud → Management in the sidebar.
  • integrations/destinations/redshift.mdx and snowflake-v2.mdx — Replaces "contact support team to obtain ARN" with direct links to cloud-metadata and iam-role-assume pages.
  • iceberg/object-storage.mdx — Updates IAM delegation note to link to iam-role-assume and cloud-metadata instead of the Snowflake-specific guide section.

<issue_title>docs: add cloud metadata guide and map it to iam-role-assume + PrivateLink setup</issue_title>
<issue_description>## Context
A user requested documentation updates from a Slack thread (2026-03-19) with this scope:

  1. Get cloud metadata.
  2. Explain how to use iam-role-assume, including which required values come from cloud metadata.
  3. Enrich PrivateLink setup steps, reusing required metadata from (1).

Reference provided by requester:

Related existing docs identified via context search:

Problem

Cloud users need several environment-specific values (account/region/network and role-assume related identifiers) to configure cross-account access and PrivateLink, but docs do not clearly centralize:

  • what "cloud metadata" values are available,
  • where to find them in the Cloud Console,
  • and how those values map directly into iam-role-assume and PrivateLink setup fields.

Current guidance is fragmented across Cloud networking and connector pages, which makes setup error-prone and increases support load.

Suggested Fix

Add a docs update package that introduces one source of truth for cloud metadata and reuses it in downstream setup guides:

  1. Add a Cloud Metadata section/page in Cloud docs:
  • Define each exposed metadata field.
  • Show where to find it in Console.
  • Clarify cloud/provider-specific differences (if any).
  1. Add an IAM role assume how-to section:
  • Explain required inputs for iam-role-assume.
  • Map each required input to the corresponding Cloud Metadata field.
  • Include a minimal end-to-end example and common failure checks.
  1. Enrich PrivateLink setup docs:
  • Add explicit "metadata prerequisites" at the start.
  • Annotate each PrivateLink step with which metadata value is required.
  • Add cross-links back to the Cloud Metadata section for fast lookup.

Acceptance criteria:

  • Users can complete IAM role assume setup and PrivateLink setup without guessing where required values come from.
  • Cloud metadata definitions are centralized and linked from both IAM role assume and PrivateLink docs.
  • Existing related pages include clear cross-links and consistent terminology.

Pull request overview

Adds centralized Cloud Console “metadata” documentation and re-links existing AWS assume-role / PrivateLink guidance to reduce reliance on support-provided values.

Changes:

  • Adds cloud/cloud-metadata.mdx as a single reference for Console-exposed environment metadata used by IAM role assume and PrivateLink.
  • Adds cloud/iam-role-assume.mdx with an end-to-end cross-account S3 role-assume walkthrough and SQL examples.
  • Updates several connector and Cloud networking pages to link to the new metadata + assume-role docs, and registers the pages in the sidebar.

  • This paragraph references an external ID, but the trust policy JSON example below still has an empty Condition: {}. If an external ID is required, update the example to include sts:ExternalId; otherwise remove the external-ID reference to keep the example consistent.
2. Configure the following additional trusted entities for your IAM Role to allow RisingWave to assume the role. Obtain the IAM role ARN and external ID from the [Cloud metadata](/cloud/cloud-metadata) page (**Settings** → **Cloud metadata**). See [Set up IAM role assume](/cloud/iam-role-assume) for a complete walkthrough.

## Metadata fields

### IAM role ARN

| Field | Example value |
|:------|:--------------|
| **IAM role ARN** | `arn:aws:iam::123456789012:role/risingwave-cloud-project-abc123` |

The AWS IAM role ARN that RisingWave Cloud uses to access AWS resources on behalf of this project. When you configure [IAM role assume](/cloud/iam-role-assume) (cross-account S3 access), you add this ARN as a trusted principal in your IAM role's trust policy.

The updated docs and connector guides reference an “external ID” from Cloud metadata, but this Cloud metadata page does not define or show that field. Add an External ID metadata field (with example value) and explain that it should be used as an sts:ExternalId condition in the IAM trust policy (and cross-link to the IAM role assume guide).

The trust policy example doesn’t include an sts:ExternalId condition, yet other pages mention an external ID for assume-role setup. If RisingWave Cloud provides an external ID, update this template to include the external ID condition (or remove external-ID references elsewhere) so users don’t end up with an incomplete or less secure trust policy.

### Step 4 — Use the role in RisingWave

Set `s3.assume_role` to the ARN of the role you created in Step 2 and set `enable_config_load = 'true'` (RisingWave Cloud only).

```sql Example: Sink using IAM role assume
CREATE SINK my_sink FROM my_source WITH (
connector = 'redshift', -- or 'snowflake_v2', 'iceberg', etc.

-- S3 staging
s3.bucket_name = '<your-bucket>',
s3.region_name = '<your-region>',
s3.path = '<your-prefix>',

-- IAM role assume (no long-term credentials needed)
s3.assume_role = 'arn:aws:iam::<your-account-id>:role/<your-role>',
enable_config_load = 'true',

This guide states enable_config_load = 'true' is “RisingWave Cloud only”, but the Redshift/Snowflake connector docs currently describe enable_config_load as “self-hosted only”. Please align the guidance across pages (either adjust this claim or update the connector docs) so users aren’t instructed to use an unsupported option.

To use this method, you need to configure an IAM Role in AWS that RisingWave can assume. This involves:
1. Obtaining the RisingWave service ARN from our [support team](mailto:cloud-support@risingwave-labs.com).
1. Obtaining the RisingWave Cloud IAM role ARN and external ID from the [Cloud metadata](/cloud/cloud-metadata) page in the Console (**Settings** → **Cloud metadata**).
2. Creating an IAM policy with the necessary S3 read/write permissions for your bucket and prefix.
3. Configuring the IAM Role's trust policy to allow the RisingWave service ARN to assume it.

For a complete step-by-step walkthrough, see [Set up IAM role assume](/cloud/iam-role-assume).

This step says to obtain an “external ID” from Cloud metadata, but the new Cloud metadata page doesn’t document an external ID field, and the instructions below don’t show how it’s used. Either (a) document the external ID and show it in the trust policy condition, or (b) remove external-ID mentions here to avoid a dead end.

This step now says to obtain the IAM role ARN and external ID from Cloud metadata, but (1) the new Cloud metadata page doesn’t document an external ID field, and (2) the subsequent bullet still talks about “RisingWave service ARN” rather than using the IAM role ARN as the trusted principal. Please align this section with the new IAM role assume guide (principal = IAM role ARN, plus external ID condition if applicable).

In RisingWave Cloud, you have two options:
- Provide `s3.access.key` and `s3.secret.key`, or
- Use IAM role delegation: grant S3 permissions to your own IAM role, allow the RisingWave Cloud tenant role to assume it, then set `s3.iam_role_arn = '<your_role_arn>'` and `enable_config_load = true`. The setup is the same as in the Snowflake sink guide: [Set up S3 IAM and role](/integrations/destinations/snowflake-v2#set-up-s3-iam-and-role).
- Use IAM role delegation: grant S3 permissions to your own IAM role, allow the RisingWave Cloud tenant role to assume it, then set `s3.iam_role_arn = '<your_role_arn>'` and `enable_config_load = true`. See [Set up IAM role assume](/cloud/iam-role-assume) for a step-by-step guide, including how to retrieve the required IAM role ARN and external ID from the [Cloud metadata](/cloud/cloud-metadata) page.

This note now says users can retrieve an external ID from Cloud metadata, but the Cloud metadata page in this PR doesn’t list it. Either add the external ID field to Cloud metadata docs or remove the external-ID mention here so the link chain is consistent.

Done in 03a0936 — added an "Accessing PrivateLink in the Console" section to privatelink-overview.mdx with the correct navigation: Connection in the left sidebar → PrivateLink tab. Also updated the step-by-step instructions in create-a-connection.mdx to match.

Audit summary (implementor):

What I checked:

  • PR diff consistency across all touched pages
  • Cross-page consistency for IAM role assume flow
  • Alignment with current docs structure and links

Findings:

  1. , , and now instruct users to get IAM role ARN + external ID from .
  2. New currently documents only: , , (no field).
  3. New trust-policy example also does not include an condition.

Verdict: Changes requested.

Final human review required: Yes.
Reason: this is identity/security guidance; inconsistent external-id instructions can cause failed setup or insecure trust policy config.

Suggested fix:

  • Either add to Cloud metadata docs and wire all references consistently,
  • Or remove “external ID from Cloud metadata” claims and point to the actual source of external ID.

Done in 03a0936 — all navigation instructions now reflect the correct path (Connection sidebar → Cloud Meta / PrivateLink tab). Added a <Frame><img> reference in cloud-metadata.mdx at /images/cloud/cloud-metadata/connection-cloud-meta.png — the actual screenshot image file needs to be committed to that path.

🔄 Cross-Review — PR #1073

Original reviewer: @implementor — Changes requested
Cross-review verdict: ⚠️ Partially agree

Agreed: The external ID inconsistency is real and correctly identified.

Additional findings missed by original review:

  • Navigation path inconsistency: redshift.mdx, snowflake-v2.mdx still say Settings → Cloud metadata but after commit 03a0936, cloud-metadata.mdx and iam-role-assume.mdx say Connection → Cloud Meta tab. Three occurrences of stale navigation paths remain in connector pages.

Disagreement on fix direction: @implementor suggested adding External ID to cloud-metadata.mdx. However, based on maintainer review comments (explicitly stating "External Id is not used"), the fix should be the opposite — remove "external ID" references from the three connector pages (redshift.mdx, snowflake-v2.mdx, iceberg/object-storage.mdx) rather than adding External ID to the metadata page.

Recommendation: Still changes requested, but the fix direction should be: (1) remove stale "external ID" references from connector pages, (2) update navigation paths from "Settings → Cloud metadata" to "Connection → Cloud Meta tab" in connector pages.
