在Docker内部获取IP

Docker内部里面，ipconfig/ip 等命令是无法使用的，正确的命令是

$ hostname -I
172.24.116.11

在宿主机获得Docker的IP

假设你已经有了一个Docker，ID是f864187a2406

$ docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' f864187a2406
172.24.116.11

$ docker inspect --format '{{ .NetworkSettings.IPAddress }}' f864187a2406
172.24.116.11

$ docker inspect f864187a2406 | egrep -e "(IPAddress|Id)"
        "Id": "f864187a24065636dc0cf9e87bdf2971fea27d4014cf981eaac6b971506b2776",
                "deployId": "8747",
            "SecondaryIPAddresses": null,
            "IPAddress": "172.24.116.11",
                    "IPAddress": "172.24.116.11",
