I installed docker to my ubuntu 14.04 laptop. I pulled docker registry image from the central registry. To fix IP address of the container to a static value, I first changed my /etc/defaults/docker and added -e lxc to DOCKER_OPTS variable.
Then to run my local registry I used the following command;
docker run \
-i -t -h myreg \
--net="none" \
--lxc-conf="lxc.network.hwaddr=91:21:de:b0:6b:61" \
--lxc-conf="lxc.network.type = veth" \
--lxc-conf="lxc.network.ipv4 = 172.17.0.20/16" \
--lxc-conf="lxc.network.ipv4.gateway = 172.17.42.1" \
--lxc-conf="lxc.network.link = docker0" \
--lxc-conf="lxc.network.name = eth0" \
--lxc-conf="lxc.network.flags = up" \
--name myreg \
-p 5000:5000 \
-d registry \
/bin/bash
Then used docker attach myreg to access to the shell of the container. After installing net-tools package, I checked the IP address of it and see that it is 172.17.0.20 as expected. I tried to ping it from my host and it was replying.
The problem is that, when I checked the configuration of this container with docker inspect myreg, the NetworkSettings part of output was as the following
"NetworkSettings": {
"Bridge": "docker0",
"Gateway": "172.17.42.1",
"IPAddress": "172.17.0.8",
"IPPrefixLen": 16,
"PortMapping": null,
"Ports": {
"5000/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "5000"
}
]
}
It was showing 172.17.0.8 as the IP address of it.It is the value that should be assigned if I was not usign lxc driver. This is becoming a problem when I use docker push command to push a tagged image to this local registry. Because,docker is using this wrong IP to push image, and throws an error log as the following
de7e1cfc] +job push(127.0.0.1:5000/mongo)

2014/07/18 17:10:22 Can't forward traffic to backend tcp/172.17.0.8:5000: dial tcp 172.17.0.8:5000: no route to host
What is the problem here? Or am I doing smt. wrong?
