我想从我的docker容器内部与在主机中使用隧道的postgres数据库连接。在主机中,我有一个指向数据库主机的隧道:
host$ sudo netstat -tulpen | grep 555
tcp 0 0 127.0.0.1:5555 0.0.0.0:* LISTEN 1000 535901 18361/ssh
tcp6 0 0 ::1:5555 :::* LISTEN 1000 535900 18361/ssh
隧道设置为:
host$ ps -aux | grep 18361
ubuntu 9619 0.0 0.0 10432 628 pts/0 S+ 10:11 0:00 grep --color=auto 18361
ubuntu 18361 0.0 0.0 46652 1420 ? Ss Nov16 0:00 ssh -i /home/ubuntu/.ssh/id_rsa -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -f -N -L 5555:localhost:5432 user@remotehost
从主机我可以启动psql命令:
host$ psql -h localhost -p 5555 --username user db_name
psql (9.3.15, server 9.5.4)
SSL connection (cipher: ECDHE-RSA-AES256-GCM-SHA384, bits: 256)
Type "help" for help.
db_name=#
当我使用网络模式 BRIDGE [我无法使用 HOST ,因为docker未正确地将容器端口暴露给主机,请参阅:https://github.com/docker/compose/issues/3442] I读到我必须使用容器ip:
3: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
link/ether 02:42:6c:01:5c:a5 brd ff:ff:ff:ff:ff:ff
inet 172.17.0.1/16 scope global docker0
valid_lft forever preferred_lft forever
inet6 fe80::42:6cff:fe01:5ca5/64 scope link
在这种情况下, 172.17.0.1
然而,当我进入容器时:
host$ docker exec -ti container_name /bin/bash
我尝试连接我:
container# psql -h 172.17.0.1 -p 5555
psql: could not connect to server: Connection refused
Is the server running on host "172.17.0.1" and accepting
TCP/IP connections on port 5555?
我缺少什么?
答案 0 :(得分:7)
你错过了bind_address,所以现在你的绑定地址是127.0.0.1。 设置隧道必须添加bind_address参数。
-L [bind_address:] port:host:hostport
E.g。
sudo ssh -f -N -L 172.17.0.1:5555:localhost:5432 user@remotehost
