I have a running Docker container (from this image). The container seems to be running correctly as far as I can see (the log-files are looking good and can connect via SSH to container and use SQLPlus inside it). However, I am unable to connect to the container from my host.
I started the container like this:
sudo docker run -d -p 49160:22 -p 49161:1521 -p 49162:8080 alexeiled/docker-oracle-xe-11g
I inspected the port-binding by this:
$ sudo docker port <container> 8080
0.0.0.0:49162
And when I do a sudo docker inspect <container>
I get among others this:
"NetworkSettings": {
"IPAddress": "172.17.0.2",
"IPPrefixLen": 16,
"Gateway": "172.17.42.1",
"Bridge": "docker0",
"PortMapping": null,
"Ports": {
"1521/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "49161"
}
],
"22/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "49160"
}
],
"8080/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "49162"
}
]
}
},
When I try to ping the container, the container responds:
$ ping 172.17.0.2
PING 172.17.0.2 (172.17.0.2) 56(84) bytes of data.

64 bytes from 172.17.0.2: icmp_req=2 ttl=64 time=0.132 ms
But I cannot connect from my host (Windows) to the Docker container. I am running Docker inside a Ubuntu 12.04 virtual machine (in VirtualBox on Windows). I am not sure if it is a problem with Docker, with my Linux VM or with VirtualBox. I forwarded a bunch ports in VirtualBox:
This is the result of sudo netstat -tpla

Any idea why I cannot connect from Windows to my (running) Docker container?
