Eliminating Code Smell With Grunt

by Gavin Lazar Suntop @gvn

Intro

I love clean code. There, I said it. I pride myself on passing strict linting standards and keeping my code easy to read. It's not just a personal proclivity, but a choice I hope benefits other developers.

My general experience with teams has been that code style is something people care about and have strong personal preferences. Typically, at some point people get tired of dealing with inconsistency and a standardization meeting is called. This is, of course, an important discussion to have. The problem that tends to occur is either lack of documentation or lack of enforcement of the agreed upon style. Additionally, new team members or contributors may not have access to a clear set of rules.

Running NGINX and CertBot Containers on the Same Host

The Problem

A lot of people run into the problem of running Let's Encrypt's CertBot Tool and an NGINX on the same container host. A big part of this has to do with CertBot needing either port 80 or 443 open for the tool to work as intended. This tends to conflict with NGINX as most people usually use port 80 (HTTP) or 443 (HTTPS) for their reverse proxy. Section 1 outlines how to configure NGINX to get this to work, and Section 2 is the Docker command to run CertBot.

1. NGINX Configuration

I use Docker Compose (docker-compose) for my NGINX server. My docker-compose.yml file looks something like this:
