我想处理 docker inspect <container1> <container2> 以便通过 jq 命令检索分配给定义网络的公开端口和 IP 地址。到目前为止，我得到的 jq '{(.[].Name): getpath(path(.[].NetworkSettings.Networks)) | .[].IPAddress}' 显然还远远不够。
附:我知道编写提供此类输出的脚本很容易，但我很好奇如何使用 jq 来做到这一点
预期输出
{
# .[].Name
"/prometheus_prometheus_1": [
[
# .[].Config.ExposedPorts
"9090/tcp"
],
{
# key = .[].NetworkSettings.Networks.<index>
# value = .[].NetworkSettings.Networks[].IPAddress
"prometheus_internal": "172.21.0.4",
"system-information": "172.28.0.2"
}
]
}

最佳答案
jq解决方案:
jq '.[] | {(.Name) : [(.Config.ExposedPorts | keys),
(.NetworkSettings.Networks | to_entries
| map({(.key): .value.IPAddress}) | add)
]
}' input
输出:
{
"/prometheus_prometheus_1": [
[
"9090/tcp"
],
{
"prometheus_internal": "172.21.0.4",
"system-information": "172.28.0.2"
}
]
}
