我有一个在其说明中使用"EXPOSE 8000"构建的docker容器.我开始这样的过程:
sudo docker run -t -i -P imagename
容器中的进程正在监听8000.
# netstat -a
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 localhost:8000 *:* LISTEN
Active UNIX domain sockets (servers and established)
Proto RefCnt Flags Type State I-Node Path
#
在主机(即容器外),我看到端口49164绑定到容器端口8000:
[S-22]jeff@siegfried:~ $ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0b0e333c6ec9 lkz:latest "/bin/bash" About an hour ago Up 6 minutes 0.0.0.0:49164->8000/tcp lkxyz__2015-01-18_202737
[S-22]jeff@siegfried:~ $
Inded,docker inspect说(除其他外)
"NetworkSettings": {
"Bridge": "docker0",
"Gateway": "172.17.42.1",
"IPAddress": "172.17.0.16",
"IPPrefixLen": 16,
"PortMapping": null,
"Ports": {
"8000/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "49164"
}
]
}
},
然而,我无法与容器交谈.外,
[S-22]jeff@siegfried:~ $ telnet localhost 49164
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
1,[S-22] jeff@siegfried:~ $
在里面,
# telnet localhost 8000
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /
[18/Jan/2015 23:00:59] "GET /" 200 4066
<!DOCTYPE html>
<html>
<head>
...
我希望telnet到49164在外面返回html,因为它在内部.
有什么建议？
