Netmap veth12/20/2023 ![]() To delete a veth interface: # ip link delete ĭetecting "idle" interfaces is a thornier problem, because if you just look at traffic you're liable to accidentally delete something that was still in use but that just wasn't seeing much activity. With respect to manually deleting veth interfaces: A veth interface isn't a bridge, so of course you can't delete one with brctl. Can you update your question with details about what distribution you're using, which kernel version, and which Docker version? These facts make me suspect that there is something fundamentally wrong in your environment. ĭocker should be cleaning up the veth interfaces automatically. It looks like you're not able to start a container: Error response from daemon: Cannot start container. Starting a single container should not increase the count of veth interfaces on your system by 2, because when Docker creates a veth pair, one end of the pair is isolated in the container namespace and is not visible from the host. ![]() WARNING: No swap limit ~ # docker version This way doesn't work (by root): ifconfig veth55d245e downĬan't delete bridge veth55d245e: Operation not permittedĮxtra interfaces now defined by transmitted traffic (if there are no activity, it's extra interface). How I can identify which interfaces are linked with existing containers, and how I can remove extra interface which was linked with removed contrainers?

After deleting container, veth interface which was linked with container should be removed. When I start any container by docker run, we get a new veth interface.
