Nit: capitalize "First".

Is this a bash-ism? If so, should the shebang be #!/bin/bash instead?

I'm not sure what you mean. Please see if the latest update addresses your concerns.

I was worried that a missing $1 would cause it to error out when nounset is in effect, but that seems to be ignored for substring substitutions (i.e., echo "${1}" would produce a "1: unbound variable" error, but echo ${1:0:1} will happily print an empty string). So never mind.

@bmoyles0117 Just noticed that this is a bash-ism, and you set the shell to /bin/sh. I got Bad substitution errors on this line in the latest container.
I've sent #161 to fix.

This is a local file — let's use COPY.

This comment is not related to the following if, so let's add a blank line after it.

Let's keep the trailing newline...
