      4. Vector area identify
      5. Textual content area identify
      6. Bedrock-managed metadata area identify

    Bedrock Knowledge Base Configuration with OpenSearch Details

    You need to not select Create but. Amazon Bedrock might be able to create the information base, however it’s worthwhile to configure OpenSearch Service entry permissions first. Copy the ARN of the brand new IAM service position that Amazon Bedrock will use for this data base (the console will show the position ARN you chose or simply created). Maintain this ARN helpful and depart the Amazon Bedrock console open (pause the creation course of right here).

    Configure fine-grained entry management permissions in OpenSearch Service

    With the IAM service position ARN copied, configure fine-grained permissions within the OpenSearch dashboard. Tremendous-grained entry management supplies role-based permission administration at a granular degree (indices, paperwork, and fields), in order that your Amazon Bedrock information base has exactly managed entry. Comply with these steps:

    1. On the OpenSearch Service console, navigate to your OpenSearch Service area.
    2. Select the URL for OpenSearch Dashboards. It sometimes seems to be like: https:///_dashboards/
    3. From the OpenSearch Dashboards interface, within the left navigation pane, select Safety, then select Roles.
    4. Select Create position and supply a significant identify, resembling bedrock-knowledgebase-role.
    5. Underneath Cluster Permissions, enter the next permissions crucial for Amazon Bedrock operations, as proven within the following screenshot:
    indices:knowledge/learn/msearch
    indices:knowledge/write/bulk*
    indices:knowledge/learn/mget*

    Amazon OpenSearch Dashboard Role Creation

    1. Underneath Index permissions:
      1. Specify the precise vector index identify you created beforehand (for instance, bedrock-kb-index).
      2. Select Create new permission group, then select Create new motion group.
      3. Add the next particular permissions, important for Amazon Bedrock Data Bases:
        indices:admin/get indices:knowledge/learn/msearch

    Understanding entry insurance policies

    When integrating OpenSearch Service Managed Cluster with Amazon Bedrock Data Bases, it’s necessary to know how entry management works throughout completely different layers.

    For same-account configurations (the place each the information base and OpenSearch Service area are in the identical AWS account), no updates to the OpenSearch Service area’s resource-based coverage are required so long as fine-grained entry management is enabled and your IAM position is appropriately mapped. On this case, IAM permissions and fine-grained entry management mappings are enough to authorize entry. Nonetheless, if the area’s resource-based coverage contains deny statements focusing on your information base service position or principals, entry might be blocked—no matter IAM or fine-grained entry management settings. To keep away from unintended failures, make certain the coverage doesn’t explicitly limit entry to the Amazon Bedrock Data Bases service position.

    For cross-account entry (when the IAM position utilized by Amazon Bedrock Data Bases belongs to a distinct AWS account than the OpenSearch Service area), you could embrace an express enable assertion within the area’s resource-based coverage for the exterior position. With out this, entry might be denied even when all different permissions are appropriately configured.
