Error response from daemon: NetworkDriver.CreateNetwork: Number of Replies should be atleast equal to number of Operations #45

Open KaustubhDhokte opened 7 years ago

I could successfully execute till step 4. Step 5, i.e. docker network create -d ovs mynet is consistently failing with this error: "Error response from daemon: NetworkDriver.CreateNetwork: Number of Replies should be atleast equal to number of Operations"

I tried debugging it, below are the logs of the container 'ubuntu_plugin_1' formed after step 4.

Running this on Ubuntu 14.04 with docker version 1.12.5, build 7392c3b. Any help is appreciated.

I can reproduce this on Ubuntu 16.04, and docker deb package version: docker-ce=5:18.09.7~3-0~ubuntu-xenial. Any idea what to do here? //cc @nerdalert @dave-tucker

My current workaround to overcome this error is as follows:

  1. Force remove existing docker networks created via the ovs driver using docker network rm --force
  2. Restart the docker daemon using service docker restart
  3. Restart the ovs-plugin containers: docker-compose up -d
