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 }}"

Overview

When you publish a self-contained dotnet linux app for .net core 2.0, and run it on a brand new machine, you'll get this error:

Failed to load', error: libunwind.so.8: cannot open shared object file: No such file or directory
Failed to bind to CoreCLR at '/export/libcoreclr.so'

You can solve this by installing system packages, but for a truly self-contained publish, pull the missing libraries from the microsoft docker image, and into your app's output. You can put them in the publish directory and distribute them with your app.

    j = json.loads(item)
    value = j.get(key)
    return value
