JQ - 配列に要素を追加し、json全体を返します。

次のように配列に要素を追加しようとしています。

jq --arg root "arn:aws:iam::$ACCOUNT_ID:root" \
              '.Statement[] | select(.Sid=="Allow use of the key") \
              | .Principal.AWS |= . + [$root]' \
 <<<$policy

これが動作している間select。

コンテンツ$policy:

{
  "Version": "2012-10-17",
  "Id": "key-consolepolicy-3",
  "Statement": [
    {
      "Sid": "Enable IAM User Permissions",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::*:root"
      },
      "Action": "kms:*",
      "Resource": "*"
    },
    {
      "Sid": "Allow access for Key Administrators",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::*:user/*"
      },
      "Action": [
        "kms:Create*",
        "kms:Describe*",
        "kms:Enable*",
        "kms:List*",
        "kms:Put*",
        "kms:Update*",
        "kms:Revoke*",
        "kms:Disable*",
        "kms:Get*",
        "kms:Delete*",
        "kms:TagResource",
        "kms:UntagResource"
      ],
      "Resource": "*"
    },
    {
      "Sid": "Allow use of the key",
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "arn:aws:iam::*:root"
        ]
      },
      "Action": [
        "kms:Encrypt",
        "kms:Decrypt",
        "kms:DescribeKey",
        "kms:ReEncrypt*",
        "kms:GenerateDataKey*",
        "kms:CreateGrant"
      ],
      "Resource": "*"
    }
  ]
}

予想される結果：

{
  "Version": "2012-10-17",
  "Id": "key-consolepolicy-3",
  "Statement": [
    {
      "Sid": "Enable IAM User Permissions",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::*:root"
      },
      "Action": "kms:*",
      "Resource": "*"
    },
    {
      "Sid": "Allow access for Key Administrators",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::*:user/*"
      },
      "Action": [
        "kms:Create*",
        "kms:Describe*",
        "kms:Enable*",
        "kms:List*",
        "kms:Put*",
        "kms:Update*",
        "kms:Revoke*",
        "kms:Disable*",
        "kms:Get*",
        "kms:Delete*",
        "kms:TagResource",
        "kms:UntagResource"
      ],
      "Resource": "*"
    },
    {
      "Sid": "Allow use of the key",
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "arn:aws:iam::*:root",
          "arn:aws:iam::$root:root" <-------------
        ]
      },
      "Action": [
        "kms:Encrypt",
        "kms:Decrypt",
        "kms:DescribeKey",
        "kms:ReEncrypt*",
        "kms:GenerateDataKey*",
        "kms:CreateGrant"
      ],
      "Resource": "*"
    }
  ]
}

追加された要素の初期jsonをどのように返しますか？

答え1

.Statement古い項目を含み、ターゲットオブジェクトを更新する新しい配列に配列を再割り当てします。

jq --arg root "arn:aws:iam::$ACCOUNT_ID:root" \
'.Statement |= map(select(.Sid=="Allow use of the key").Principal.AWS |= . + [$root])' <<<$policy
