从Docker版本1.10.3开始，构建20f81dd

除非你告诉Docker，否则Docker总是在网桥网络中启动你的容器。因此，您可以尝试以下命令：

docker network inspect bridge

然后应该返回一个Containers部分，该部分将显示正在运行的容器的IP地址。

[
    {
        "Name": "bridge",
        "Id": "40561e7d29a08b2eb81fe7b02736f44da6c0daae54ca3486f75bfa81c83507a0",
        "Scope": "local",
        "Driver": "bridge",
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "172.17.0.0/16"
                }
            ]
        },
        "Containers": {
            "025d191991083e21761eb5a56729f61d7c5612a520269e548d0136e084ecd32a": {
                "Name": "drunk_leavitt",
                "EndpointID": "9f6f630a1743bd9184f30b37795590f13d87299fe39c8969294c8a353a8c97b3",
                "IPv4Address": "172.17.0.2/16",
                "IPv6Address": ""
            }
        },
        "Options": {
            "com.docker.network.bridge.default_bridge": "true",
            "com.docker.network.bridge.enable_icc": "true",
            "com.docker.network.bridge.enable_ip_masquerade": "true",
            "com.docker.network.bridge.host_binding_ipv4": "0.0.0.0",
            "com.docker.network.bridge.name": "docker0",
            "com.docker.network.driver.mtu": "1500"
        }
    }
]

按名称引用容器：

docker run ... --name pg-master

然后按名称获取IP地址：

MASTER_HOST=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' pg-master)

使用Python新API：

import docker

client = docker.DockerClient()
container = client.containers.get("NAME")
ip_add = container.attrs['NetworkSettings']['IPAddress']
print(ip_add)

docker inspect <container id> | grep -i ip

例如：

docker inspect 2b0c4b617a8c | grep -i ip

docker inspect＜container id＞| grep-i“ipad地址”

Inspect对我不起作用。可能是因为我使用了-net主机和一些名称空间。

总之，我发现这很有效：

docker exec -i -t NAME /sbin/ifconfig docker0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'
