通过JQ和BASH / SHELL获取JSON文档的第三个元素

Question

我在AWS中有一些实例。我想通过特殊标签获取这些应用程序。

我的AWS CLI命令，通过标签IAMOWNER：

aws ec2 describe-instances --filters "Name=instance-state-name,Values=running" "Name=tag:Owner,Values=IAMOWNER" --query "Reservations[*].Instances[*].[InstanceId,PrivateIpAddress,Tags[?Key=='Name'].Value[]]" --region us-west-2

此命令的输出：

[
    [
        [
            "i-d21eei21e912e0e91",
            "192.168.1.203",
            [
                "mycentralapplication-DEV-10"
            ]
        ]
    ],
    [
        [
            "i-ddaswed1e12415155",
            "192.168.1.210",
            [
                "mycentralapplication-DEV-103"
            ]
        ]
    ],
    [
        [
            "i-dass1241211agh354",
            "192.168.1.202",
            [
                "myindexapplication-DEV-53"
            ]
        ]
    ],
    [
        [
            "i-2143214251assaa11",
            "192.168.1.211",
            [
                "myserviceapplication-DEV-52"
            ]
        ]
    ],
    [
        [
            "i-d2112421521assas1",
            "192.168.1.207",
            [
                "mycentralapplication-DEV-10"
            ]
        ]
    ],
    [
        [
            "i-sadas11112424111a",
            "192.168.1.196",
            [
                "myapplication-DEV-106"
            ]
        ]
    ]
]

问题。如何通过mycentralapplication或jq中的bash库获取shell例如的元素？例如，我只需要在输出中接收mycentralapplication

[
    [
        [
            "i-d21eei21e912e0e91",
            "192.168.1.203",
            [
                "mycentralapplication-DEV-10"
            ]
        ]
    ],
    [
        [
            "i-ddaswed1e12415155",
            "192.168.1.210",
            [
                "mycentralapplication-DEV-103"
            ]
        ]
    ],
    [
        [
            "i-d2112421521assas1",
            "192.168.1.207",
            [
                "mycentralapplication-DEV-10"
            ]
        ]
    ]
]

我该怎么做？

aws ec2 describe-instances --filters "Name=instance-state-name,Values=running" "Name=tag:Owner,Values=IAMOWNER" --query "Reservations[*].Instances[*].[InstanceId,PrivateIpAddress,Tags[?Key=='Name'].Value[]]" --region us-west-2 | jq -r "mycentralapplication"

在这种情况下，我返回错误。问题是，是否可以通过jq解决此任务？还是我必须使用grep等...？
