Day 4: Scripting Docker Commands With Spinup.sh

In Day 3, I included a blurb from my DevOps-y friends about the natural progression of abstractions on top of containers:

You usually start with docker run CLI commands and graduate to tools with more layers of abstraction as you need them. Docker-compose comes next, followed by automating several commands with Bash scripts, which is eventually followed by Kubernetes.

I also shared with you a better way to handle switches in Bash scripts. Today I’ll show you how I moved from running my own Docker commands to running off of one shell script with a handful of flags.

Day 3: Fun With Flags

First off, some housekeeping. I can already tell that coming up with a daily post is going to be harder than my buddy Alex had with his SVG work. He had one animation to complete every day. I’m spending all month working towards one larger goal.

However, I’ll do my best to share something I learn every day, even if it’s small.


Background

I bought Nigel Poulton’s book bundle from LeanPub and am starting to dig into those, but learned something neat recently that I thought I would share.

When I was still at the courts, I was teaching myself how to use containers as quickly as I was implementing them in projects. While learning how to manage multiple sets of containers, I spoke with my college friends who were in DevOps-y roles about the tools they used. It shocked me to hear everyone say the same thing:

From Barely Functional PHP To Conference Worthy Web Apps In Under Two Years

I’ve only been in the web development game for a little under two years, but I’m building applications for a federal agency that are getting me invited to speak at conferences. It took me a while to figure out how to get to that point, and I didn’t have anyone available to give me a road map when I started. I spent a long time teaching myself, and in retrospect there are definitely easier paths to take. So here’s my attempt to set new developers on the right track.
