I'm in macOS Catalina 10.15.6 running docker 19.03.8.

When I follow the instructional video and docker build -t simpleserver ., the first RUN command that installs nodejs and npm halts in a menu asking me to select my time zone interactively. Apparently docker builds aren't interactive, so this just hangs, and there's no way around it.

If I add ARG DEBIAN_FRONTEND=noninteractive near the beginning of the Dockerfile, then the first install appears to go fine, but I run up against an issue when I RUN npm install -g nodemon: "The command '/bin/sh -c npm install -g nodemon' returned a non-zero code: 1"

Slipping in to an ubuntu image with docker run -it --rm ubuntu bash, I can run those commands in sequence without a problem. (I get a different problem when I run ln -s /usr/bin/nodejs /usr/bin/node, because it tells me that symbolic link already exists, but that's beside the point.)

I've tried adding ENV TZ=America/Denver near the top of the Dockerfile in the hope this would allow the installer to just use it and not have to ask and not be confused by the absence of a timezone specification, but this was in vain.

tl;dr Something is broken.

Error applying plan:

Currently we've got a Github check running the project in CircleCI, but we don't actually have it configured. As part of this issue, we should:

• make a decision if we want a CircleCI pipeline to run - e.g. some terraform validate steps, or some other relevant steps
• if yes, then add a configuration file & make sure it passes
• if no, then disable this check for the project from CircleCI here

Why?
Currently, almost every PR in this repo is appearing with a broken build because of the missing CircleCI configuration. This is not a big problem, so this task is more a housekeeping type of job.
