docker - 如何在docker volume ls --format中打印嵌套的字典成员值

Question

我想使用以下命令打印Docker卷的后端卷名称
docker 卷ls --format，

以下是docker volume inspect的输出

docker volume inspect 3812bd5a8e286eb9ff9
[
    {
        "CreatedAt": "0001-01-01T00:00:00Z",
        "Driver": "oie",
        "Labels": null,
        "Mountpoint": "",
        "Name": "3812bd5a8e286eb9ff9",
        "Options": null,
        "Scope": "global",
        "Status": {
            "volume_detail": {
                "oie_vol_name": "dcv-TL0SoIuHQvCStS1F-B5i-A",
                "backend": "4000",
                "compression": null,
                "cpg": "cpg1",
                "domain": null,
                "flash_cache": null,
                "fsMode": null,
                "fsOwner": null,
                "mountConflictDelay": 30,
                "provisioning": "thin",
                "size": 20,
                "snap_cpg": "cpg1"
            }
        }
    }
]

我可以使用docker volume ls -f driver=hpe --format "{{.Driver}}"提取驱动程序名称

但是当我想拉 "Status": { "volume_detail": using " docker volume ls -f driver=hpe --format "{{.Status{.volume_detail{.oie_vol_name}}}}""里面的字段oie_vol_name时

表明

Template parsing error: template: :1: unexpected bad character U+007B '{' in command

试试这个

docker volume inspect -f "{{ .Status.volume_detail.oie_vol_name }} 3812bd5a8e286eb9ff9

希望这可以帮助。
