Step 2: Configuring the external objectstore

Supported objectstores

Automation Suite supports the following external objectstores:

• Azure Storage (Azure Blob Storage)
• AWS S3
• S3 compatible objectstore.

Note:

• Only some S3-compatible objectstores are compatible with Automation Suite. Many storage providers do not fully support the S3 storage APIs required by the products installed on Automation Suite.
• For Automation Suite to function properly when using pre-signed URLs, you must make sure that your external objectstore is accessible from the Automation Suite cluster, browsers, and all your machines, including workstations and robot machines.
• When configuring the external object storage, you must follow the naming rules and conventions from your provider for both bucket_name_prefix and bucket_name_suffix. In addition to that, the suffix and prefix must have a combined length of no more than 25 characters, and you must not end the prefix or start the suffix with a hyphen (-) as we already add the character for you automatically.

• The Server Side Encryption with Key Management Service (SSE-KMS) can only be enabled on the Automation Suite buckets deployed in any region created after January 30, 2014.

  SSE-KMS functionality requires pure SignV4 APIs. Regions created before January 30, 2014 do not use pure SignV4 APIs due to backward compatibility with SignV2. Therefore, SSE-KMS is only functional in regions that use SignV4 for communication. To find out when the various regions were provisioned, refer to the AWS documentation.

S3-compatible objectstore requirements

Your S3-compatible objectstore must have the following APIs for the products you plan to install on Automation Suite:

HEAD_OBJECT	N/A						N/A			N/A

S3-compatible objectstore configuration

Make sure the following CORS policy is configured at your objectstore server or the bucket level.

This is the CORS policy in JSON format:

JSON

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "POST",
            "GET",
            "HEAD",
            "DELETE",
            "PUT"
        ],
        "AllowedOrigins": [
            "https://{{fqdn}}"
        ],
        "ExposeHeaders": [
            "etag",
            "x-amz-server-side-encryption",
            "x-amz-request-id",
            "x-amz-id-2"
        ],
        "MaxAgeSeconds": 3000
    }
]

This is the CORS policy in XML format:
