Let's Encrypt Amazon EC2 Heroku Node.js Vue.js JavaScript

We recently went through building and setting up free SSL for custom domains for our #SaaS customers. This feature is used for hosting public status pages and dashboards under the customers' own domain name.

We are in the #Node.js, #AWS and #Heroku world, but most of the things we learned are applicable to other stacks too.

The post linked goes into three things:

1. Configuring the Let's Encrypt / ACME client called Greenlock.
2. Getting DNS right on Amazon Route 53
3. Actually determining what content to serve based on hostname.

All seem pretty straightforward, but there are gotcha's at each step.

Hope this helps other budding SaaS operators or ops peeps that need this functionality.
