    When put at the root of my Windows user folder C:\Users\[my username]\Dockerfile
    it will fail to find context of related files required in the build

    COPY failed: stat /mnt/sda1/var/lib/docker/tmp/docker-builder746762051/nodejs/package.json: no such file or directory

    Hence, in separate sub-directory:

    <docker Windows User root>
  |
   nodejs (dir)
         |___ Dockerfile
              .dockerignore
              resources (dir)
                 |____packages.json
                      serverhello.js

    COPY success during build:

    cd nodejs
docker build -t bandono/simplenodeweb .

    Instead of -d that exited with code 126 the whole time, run the serverhello.js using:

    $ docker run -p 8286:8080 bandono/simplenodeweb node serverhello.js
Running on http://0.0.0.0:8080

    References (which not working at first running with -d):

    [1] nodejs org
    [2] DigitalOcean

    Change internet default route in Mac OS X to USB HSDPA modem stick with LAN’ certain subnet routed via a gateway in WiFi (en1).

    In my case DNS will go with the modem interface setting remain routed via USB modem stick

    before routing:

    $ netstat -nr
 
Routing tables
 
Internet:
Destination        Gateway            Flags        Refs      Use   Netif Expire
default            10.64.64.64        UGSc           72      137    ppp0
default            link#4             UCSI            0        0     en0
default            10.1.1.1          UGScI           0        0     en1

    Delete and add routes (desired LAN subnet 192.168.1.0/24:

    sudo route -n delete default 10.1.1.1
sudo route -n add default 10.64.64.64
sudo route -n add 192.168.1.0/24 10.1.1.1

    after routing:

    $ netstat -nr
