Does DSS support the switch of IAM role, as described here? https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-api.html

To access an S3 bucket in other account we would need to switch and use a cross account role,

Thanks

    Hi, DSS now supports switching IAM roles for access to S3 connections. The best practice here is to separate out your s3 access policy into a separate role and then set up assumeRole permissions on your connection. In detail:
    1. Create a separate role with your s3 access policy. See here for an example of the inline policy. We'll call this role Dataiku-DSS-S3-Access:
    {
    "Version": "2012-10-17",
    "Statement": [
    {
    "Effect": "Allow",
    "Action": [
    "s3:PutObject",
    "s3:GetObject",
    "s3:DeleteObject",
    "s3:GetEncryptionConfiguration",
    "s3:ListBucketMultipartUploads",
    "s3:AbortMultipartUpload",
    "s3:ListBucket",
    "s3:GetBucketLocation",
    "s3:ListMultipartUploadParts"
    ],
    "Resource": [
    "arn:aws:s3:::dataiku-bucket",
    "arn:aws:s3:::dataiku-bucket/*"
    ]
    }
    ]
    }
    2. Assuming that your roles are in the same account you can just update the trust policy of your new role to allow your instance profile role to assume it:
    {
    "Version": "2012-10-17",
    "Statement": [{
    "Sid": "DSS-S3-AccessTrustPolicy",
    "Effect": "Allow",
    "Action": "sts:AssumeRole",
    "Principal": {
    "AWS": "arn:aws:iam::XXXXXX:role/name-of-your-instance-profile-role"
    }
    }]
    }
    3. If you're going cross account, you'll need to give assumeRole permissions to your instance profile role as well:
    {
    "Version": "2012-10-17",
    "Statement": [
    {
    "Effect": "Allow",
    "Action": [
    "iam:GetRole",
    "iam:PassRole",
    "iam:AssumeRole"
    ],
    "Resource": [
    "arn:aws:iam::XXXXXXXXX:role/Dataiku-DSS-S3-Access"
    ]
    }
    ]
    }
    4. In Dataiku, switch your connection to use this new role:
