Hi,
have a question about docker networking.
Actually in my OMV dashboard i see 16 veth interfaces listed.
I know that every container has a veth pair and only one is visible to the host.
First strange fact is that in the OMV dashboard i see both for a container i don't know the name of.
root@DK:~# ethtool -S vethdc5188e
NIC statistics:
peer_ifindex: 15
root@DK:~# ip link | grep 15:
15: veth0346e0c@vethdc5188e: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default
root@DK:~#
In the dashboard i see both veth0346e0c and vethdc5188e. I should see only one.
From terminal i see:
root@DK:~# ifconfig | grep veth
veth2753637: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
veth10bd486: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
veth1fa2224: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
veth285b92e: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
veth413482f: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
veth5c163a9: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
veth7dd03d3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
veth9eb0924: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
vetha9447f5: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
vethd0fa3a0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
vethd78d0b8: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
vethdc5188e: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
vethec638a6: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
vethfa8d96f: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
vethfcc940e: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
root@DK:~#15 veth interfaces here. vethdc5188e is one of them, and is UP but not RUNNING.
So my questions here are:
1. Why from the dashboard i see an entire veth pair and from terminal i only see one? (both have the eth icon grey next to them).
2. I managed to find to which container is attached every veth interface. All but not for vethdc5188e.
How can i understand what is this interface?
