Setup automatic LetsEncrypt wildcard certificate renewal on Ubuntu server 18.04 with Namecheap

All credits go to by Bryan Roessler for his original post that I followed on how to setup LetsEncrypt wildcard certificate auto-renewal with Namecheap. I highly recommend you read his tutorial first and if you bump into issues, check out this gist next.

Unfortunately the original article is not up-to-date and doesn't have the option to leave comments so I can't communicate with the author for updates so I decided to write the updates in a Gist. I highlighted the sections that required an updated with Correction #:. I managed to get the correct setup with the help of the amazing guys at LetsEncrypt community. Here's the help thread.

Concise guide to golang/dep

Overview

This gist is based on the information available at golang/dep, only slightly more terse and annotated with a few notes and links primarily for my own personal benefit. It's public in case this information is helpful to anyone else as well.

I initially advocated Glide for my team and then, more recently, vndr. I've also taken the approach of exerting direct control over what goes into vendor/ in my Dockerfiles, and also work from isolated GOPATH environments on my system per project to ensure that dependencies are explicitly found under vendor/.

At the end of the day, vendoring (and committing vendor/) is about being in control of your dependencies and being able to achieve reproducible builds. While you can achieve this manually, things that are nice to have in a vendoring tool include:
