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):

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 Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 10.64.64.64 UGSc 21 0 ppp0 default link#4 UCSI 0 0 en0 default 10.1.1.1 UGScI 0 0 en1 10.1.1/24 link#5 UCS 6 0 en1 ... 192.168.1 10.1.1.1 UGSc 0 0 en1 ... |

Check apache2 enabled modules:
$ sudo apache2ctl -M Loaded Modules: core_module (static) log_config_module (static) logio_module (static) mpm_prefork_module (static) ... |
mod_rewrite (rewrite_module usually manipulated in .htaccess) and ssl (for HTTPS) for examples aren’t enabled by default in Ubuntu’ installation of apache2.
Enable one or more of them via:
$ sudo a2enmod |
