Question

我一直在尝试设置docker环境。让我感到困扰的一个问题是，我的docker容器无法访问我的主机。

在容器A中：

ping 192.168.39.184 # host ip

没有回应

# traceroute 192.168.39.184
traceroute to 192.168.39.184 (192.168.39.184), 30 hops max, 46 byte packets
 1  *  *  *
 2  *  *  *

 4  *  *  *

 6  *  *  *
 7  *  *  *
 8  *  *  *
 9  *  *  *
10  *  *  *
11  *  *  *

容器使用用户定义的网桥：

 "Networks": {
                "DB_DOCKER_NETWORK": {
                    "IPAMConfig": {},
                    "Links": null,
                    "Aliases": [
                        "8efacc8c4dbd"
                    ],
                    "NetworkID": "3af9e7395bbcf0d374772245bac50fb714479ed17abcefc0214bb3dca9ef630c",
                    "EndpointID": "5aef17340477f0bff4169faeca2c0a5ed8dc10d2a628a2f1c6f0b6503f5dc6f3",
                    "Gateway": "172.20.0.1",
                    "IPAddress": "172.20.0.2",
                    "IPPrefixLen": 16,
                    "IPv6Gateway": "",
                    "GlobalIPv6Address": "",
                    "GlobalIPv6PrefixLen": 0,
                    "MacAddress": "02:42:ac:14:00:02",
                    "DriverOpts": {}
                },

并且容器可以ping通另一台主机（192.168.39.216）：

# ping 192.168.39.216
PING 192.168.39.216 (192.168.39.216): 56 data bytes
64 bytes from 192.168.39.216: seq=0 ttl=63 time=0.178 ms
64 bytes from 192.168.39.216: seq=1 ttl=63 time=0.229 ms

主机和解析配置为：

# cat /etc/hosts
127.0.0.1   localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

cat /etc/resolv.conf 
search scloudm
nameserver 127.0.0.11
options ndots:0

docker容器无权托管
