HOWTO: Create Your Own Self-Signed Certificate with Subject Alternative Names Using OpenSSL in Ubuntu Bash for Window

HOWTO: Create Your Own Self-Signed Certificate with Subject Alternative Names Using OpenSSL in Ubuntu Bash for Window

Overview

My main development workstation is a Windows 10 machine, so we'll approach this from that viewpoint.

Recently, Google Chrome started giving me a warning when I open a site that uses https and self-signed certificate on my local development machine due to some SSL certificate issues like the one below:

How to get Kubernetes running on Windows 10

Kubernetes On Windows

Early in August 2016 Microsoft released the Windows 10 Anniversary Update. There were a number of changes, but the one that got me to actually take the time to install the update was "Bash on Ubuntu on Windows". This feature would install Ubuntu Linux without the kernel. It would run linux in user-mode. Linux would run the commands while Windows does all the work/processing.

For an upcoming project I needed to get Kubernetes running. Being as Kubernetes is not able to be run in Windows the normally accepted way to procees is to create a virtual Linux box and run it from there. I wanted to see if Kubernetes would run in Bash on Ubuntu on Windows.

This is how I got it to work:

retrieve EC2's region from instance metadata

Sometimes you want to retrieve EC2 insntances' region information.

You can query that information through instance metadata(169.254.169.254).

$ curl --silent http://169.254.169.254/latest/dynamic/instance-identity/document
{
  "privateIp" : "172.31.2.15",
  "instanceId" : "i-12341ee8",
  "billingProducts" : null,
 "instanceType" : "t2.small",
