使用Python新API：

import docker

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

码头工人检查MY_CONTAINER | jq-r'。[].网络设置.网络[].IP地址'

plus

优雅的语法灵活（一旦你使用jq，你可以在任何地方使用它，有json，非常有用）强大的

减

需要安装jq（例如apt-get-installjq）

对于窗口10：

docker inspect --format "{{ .NetworkSettings.IPAddress }}"  containerId

docker inspect --format "{{ .NetworkSettings.Networks.mynetwork.IPAddress }}" <containername or containerID here>

以上内容适用于已使用

docker create network mynetwork 

我的回答：

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}} %tab% {{.Name}}' $(docker ps -aq
) | sed 's#%tab%#\t#g' | sed 's#/##g' | sort -t . -k 1,1n -k 2,2n -k 3,3n -k 4,4n

也可以作为bash别名：

docker-ips() {   docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}} %tab% {{.Name}}' $(docker ps -aq) | sed 's#%tab%#\t#g' | sed 's#/##g' | sort -t . -k 1,1n -k 2,2n -k 3,3n -k 4,4n }

输出按IP地址排序，制表符分隔：

# docker-ips
172.18.0.2       memcached
172.18.0.3       nginx
172.18.0.4       fpm-backup
172.18.0.5       dns
172.18.0.6       fpm-beta
172.18.0.7       exim
172.18.0.8       fpm-delta
172.18.0.9       mariadb
172.18.0.10      fpm-alpha
172.19.0.2       nextcloud-redis
172.19.0.3       nextcloud-db
172.19.0.4       nextcloud

这是我今天用Python开发的一个解决方案，使用docker inspect容器JSON输出作为数据源。

我有很多容器和基础设施需要检查，我需要从任何容器中以快速、漂亮的方式获取基本的网络信息。这就是我写这个剧本的原因。

重要提示：从1.9版开始，Docker允许您创建多个网络并将它们连接到容器。

#!/usr/bin/python

import json
import subprocess
import sys

try:
    CONTAINER = sys.argv[1]
except Exception as e:
    print "\n\tSpecify the container name, please."
    print "\t\tEx.:  script.py my_container\n"
    sys.exit(1)

# Inspecting container via Subprocess
proc = subprocess.Popen(["docker","inspect",CONTAINER],
                      stdout=subprocess.PIPE,
                      stderr=subprocess.STDOUT)

out = proc.stdout.read()
json_data = json.loads(out)[0]

net_dict = {}
for network in json_data["NetworkSettings"]["Networks"].keys():
    net_dict['mac_addr']  = json_data["NetworkSettings"]["Networks"][network]["MacAddress"]
    net_dict['ipv4_addr'] = json_data["NetworkSettings"]["Networks"][network]["IPAddress"]
    net_dict['ipv4_net']  = json_data["NetworkSettings"]["Networks"][network]["IPPrefixLen"]
    net_dict['ipv4_gtw']  = json_data["NetworkSettings"]["Networks"][network]["Gateway"]
    net_dict['ipv6_addr'] = json_data["NetworkSettings"]["Networks"][network]["GlobalIPv6Address"]
    net_dict['ipv6_net']  = json_data["NetworkSettings"]["Networks"][network]["GlobalIPv6PrefixLen"]
    net_dict['ipv6_gtw']  = json_data["NetworkSettings"]["Networks"][network]["IPv6Gateway"]
    for item in net_dict:
        if net_dict[item] == "" or net_dict[item] == 0:
            net_dict[item] = "null"
    print "\n[%s]" % network
    print "\n{}{:>13} {:>14}".format(net_dict['mac_addr'],"IP/NETWORK","GATEWAY")
    print "--------------------------------------------"
    print "IPv4 settings:{:>16}/{:<5}  {}".format(net_dict['ipv4_addr'],net_dict['ipv4_net'],net_dict['ipv4_gtw'])
    print "IPv6 settings:{:>16}/{:<5}  {}".format(net_dict['ipv6_addr'],net_dict['ipv6_net'],net_dict['ipv6_gtw'])

输出为：

$ python docker_netinfo.py debian1
