泊坞检查格式中检索特定网络的IP

我用群模式，我想获得的服务的VirtualIP在特定网络上：6yhxlmtq69zaojpy57xdvaeiw 结果应该是：10.0.0.3/24泊坞检查格式中检索特定网络的IP

     } 
    }

使用此命令我得到：

docker service inspect spark-master -f {{.Endpoint.VirtualIPs}} 
[{4w6z3pc3zspunw4n6199594ve 10.255.0.9/16} {6yhxlmtq69zaojpy57xdvaeiw 10.0.0.3/24}]

如何指定获得6yhxlmtq69zaojpy57xdvaeiw网络的VirtualIp正确的格式？

看到我的答案在http://stackoverflow.com/questions/30342796/how-to-get-env-variable-when-doing-docker-inspect/30353018#30353018你应该能够提取相关部分 – user2915097

什么给docker服务检查spark-master -f {{（index（.Endpoint.VirtualIPs）0）.4w6z3pc3zspunw4n6199594ve}} – user2915097

我误读了，更好的尝试'docker service inspect spark-master -f {{ （.Endpoint.VirtualIPs）1）.6yhxlmtq69zaojpy57xdvaeiw}}' – user2915097

docker service inspect spark-master -f '{{range $i, $value := .Endpoint.VirtualIPs}} {{if eq $value.NetworkID "6yhxlmtq69zaojpy57xdvaeiw" }}{{$value.Addr}}{{end}}{{end}}'

和我玩这个我可以得到更多补偿lex：'''docker service inspect spark-master -f'{{$ net：=（index.Spec.TaskTemplate.Networks 0）.Target}} {{range $ i，$ value：= .Endpoint.VirtualIPs}} {{if eq $ value.NetworkID $ net}} {{$ value.Addr}} {{end}} {{end}}'''' – rolele
