Docker network create error: "Error response from daemon: failed to check bridge interface existence: numerical result out of range"

README.md

I recently hit this problem, while using ansible to create docker networks:

- name: Construct Default docker networks
  shell: "docker network create 
            -o com.docker.network.bridge.enable_icc=false 
            -o com.docker.network.bridge.name={{item.networkName}}
            --subnet {{item.subnet}} {{item.networkName}}"
  with_items: "{{ docker_networks }}"

The error looks like this:

Error response from daemon: failed to check bridge interface existence: numerical result out of range

The problem is that the name you're passing to com.docker.network.bridge.name is too long.

Change it to be 15 characters or less.
