Json 如何使用JQ访问父字典密钥,json,jq,Json,Jq,我正在尝试使用JQ从docker inspect输出JSON片段。。。包括所有网络的详细信息。问题是网络的编号和名称各不相同 如果您共享了一个代码段，如果这有帮助 我的第一次尝试是有效的，因为我明确地命名了每个网络、入口和webnet。我希望我的最终解决方案是不要在过滤器中提及网络名称，而是将它们包含在输出中 jq '.[] | { Networks: (.NetworkSettings .Networks | {ingress: .ingress .IPAddress, webnet: .we

我正在尝试使用JQ从docker inspect输出JSON片段。。。包括所有网络的详细信息。问题是网络的编号和名称各不相同

如果您共享了一个代码段，如果这有帮助

我的第一次尝试是有效的，因为我明确地命名了每个网络、入口和webnet。我希望我的最终解决方案是不要在过滤器中提及网络名称，而是将它们包含在输出中

jq '.[] | { Networks: (.NetworkSettings .Networks | {ingress: .ingress .IPAddress, webnet: .webnet .IPAddress})}' 

{
  "Networks": {
    "ingress": "10.255.0.5",
    "webnet": "10.0.0.3"
  }
}

"ingress"
"webnet"

{
  "Name": "/nginx.1.attiwcma8h39wclpsncp608tk",
  "Id": "f2ee9caae862326a7a62304659121c506f8afb9d74080475702da3595576937a",
  "Path": "nginx",
  "Networks": {
    "ingress": {
      "IPAddress": "10.255.0.5",
      "NetworkID": "zznyce2va5pfggq14su51zygn"
    },
    "webnet": {
      "IPAddress": "10.0.0.3",
      "NetworkID": "g66ea3npnaiwvvdy66rijt5yo"
    }
  }
}
这是输出

jq '.[] | { Networks: (.NetworkSettings .Networks | {ingress: .ingress .IPAddress, webnet: .webnet .IPAddress})}' 

{
  "Networks": {
    "ingress": "10.255.0.5",
    "webnet": "10.0.0.3"
  }
}

"ingress"
"webnet"

{
  "Name": "/nginx.1.attiwcma8h39wclpsncp608tk",
  "Id": "f2ee9caae862326a7a62304659121c506f8afb9d74080475702da3595576937a",
  "Path": "nginx",
  "Networks": {
    "ingress": {
      "IPAddress": "10.255.0.5",
      "NetworkID": "zznyce2va5pfggq14su51zygn"
    },
    "webnet": {
      "IPAddress": "10.0.0.3",
      "NetworkID": "g66ea3npnaiwvvdy66rijt5yo"
    }
  }
}
我做了一些研究，发现我可以将变量分配给我想要的节点，但不能分配给父键

jq '.[] | .NetworkSettings .Networks[] as $parent | { IPAddress: $parent .IPAddress, NetworkID: $parent .NetworkID }'

{
  "IPAddress": "10.255.0.5",
  "NetworkID": "zznyce2va5pfggq14su51zygn"
}
{
  "IPAddress": "10.0.0.3",
  "NetworkID": "g66ea3npnaiwvvdy66rijt5yo"
}
以下是节点的详细信息，但没有父密钥

jq '.[] | .NetworkSettings .Networks[] as $parent | { IPAddress: $parent .IPAddress, NetworkID: $parent .NetworkID }'

{
  "IPAddress": "10.255.0.5",
  "NetworkID": "zznyce2va5pfggq14su51zygn"
}
{
  "IPAddress": "10.0.0.3",
  "NetworkID": "g66ea3npnaiwvvdy66rijt5yo"
}
接下来，我可以访问密钥，但无法访问详细信息

jq '.[] | .NetworkSettings .Networks | keys[] as $key | $key'
这是输出

jq '.[] | { Networks: (.NetworkSettings .Networks | {ingress: .ingress .IPAddress, webnet: .webnet .IPAddress})}' 

{
  "Networks": {
    "ingress": "10.255.0.5",
    "webnet": "10.0.0.3"
  }
}

"ingress"
"webnet"

{
  "Name": "/nginx.1.attiwcma8h39wclpsncp608tk",
  "Id": "f2ee9caae862326a7a62304659121c506f8afb9d74080475702da3595576937a",
  "Path": "nginx",
  "Networks": {
    "ingress": {
      "IPAddress": "10.255.0.5",
      "NetworkID": "zznyce2va5pfggq14su51zygn"
    },
    "webnet": {
      "IPAddress": "10.0.0.3",
      "NetworkID": "g66ea3npnaiwvvdy66rijt5yo"
    }
  }
}
如何将父项名称作为标签访问，并输出子项详细信息？我想我需要像下面这样的东西，但不知道它是否正确或如何到达那里

($key): { IPAddress: $parent[$key] .IPAddress, NetworkID: $parent[$key] .NetworkID }
我的最终解决方案是将多个级别的细节与所有网络的细节结合起来。我想如果我能解决上面的问题，我可以解决下面的问题，但我会把它包括在内，以防它有所帮助

.[] | {Name: .Name, Id: .Id, Path: .Path, Networks: (.NetworkSettings .Networks | {ingress: { IPAddress: .ingress .IPAddress, NetworkID: .ingress .NetworkID }, 
webnet: {IPAddress: .webnet .IPAddress, NetworkID: .webnet .NetworkID}})}
这是输出

jq '.[] | { Networks: (.NetworkSettings .Networks | {ingress: .ingress .IPAddress, webnet: .webnet .IPAddress})}' 

{
  "Networks": {
    "ingress": "10.255.0.5",
    "webnet": "10.0.0.3"
  }
}

"ingress"
"webnet"

{
  "Name": "/nginx.1.attiwcma8h39wclpsncp608tk",
  "Id": "f2ee9caae862326a7a62304659121c506f8afb9d74080475702da3595576937a",
  "Path": "nginx",
  "Networks": {
    "ingress": {
      "IPAddress": "10.255.0.5",
      "NetworkID": "zznyce2va5pfggq14su51zygn"
    },
    "webnet": {
      "IPAddress": "10.0.0.3",
      "NetworkID": "g66ea3npnaiwvvdy66rijt5yo"
    }
  }
}

这是您最初使用固定网络密钥的解决方案，只需稍微重新格式化即可

    .[]
  | {
       Name: .Name,
       Id:   .Id,
       Path: .Path,
       Networks: (
            .NetworkSettings.Networks
          | {
             ingress: { IPAddress: .ingress.IPAddress, NetworkID:.ingress.NetworkID }, 
             webnet:  { IPAddress: .webnet.IPAddress,  NetworkID:.webnet.NetworkID  }
          }
       )
     }
这里有一个更通用的解决方案，它使用reduce和keys来构造Networks对象

    .[]
  | {
       Name: .Name,
       Id:   .Id,
       Path: .Path,
       Networks: (
            .NetworkSettings.Networks as $n
          | reduce ($n|keys[]) as $k (
               {}
             ; .[$k] = ( $n[$k] | {IPAddress, NetworkID} )
            )
       )
     }
使用|=来更新网络，而不是构造新对象，可以稍微简化

    .[]
  | {
       Name: .Name,
       Id:   .Id,
       Path: .Path,
       Networks: (
            .NetworkSettings.Networks
          | reduce keys[] as $k (
               .
             ; .[$k] |= {IPAddress, NetworkID}
            )
       )
     }
谢谢它给了我想要的结果，但我需要一段时间来消化它。
