I get your point but don't think you're getting mine. In a bigger project / organization? Yes, let's have those processes and tools. But for simple apps as described in the article? Use a correspondingly simple solution. As always in software development, it's all about context.

I get your point, and I disagree on opinion. I and many others have had success using containerized devenvs on projects both large and small, and have likewise felt some pain with respect to repeatability when not - especially with the Python stack. Containers are synonymous with repeatability. Your future self is just another collaborator, and they’ll appreciate it down the line when they’ve got a new laptop and new env, for example ;)

I agree. With you and with the other opinions (why should only one perspective be right?).

I've been the lead developer on teams where I introduced Docker to solve consistency/reproducibility issues in AWS and Azure.

I've also done smaller applications in DotNet Core, Go, Node, Python, and Ruby. In those cases I've use other alternatives, including:

- Known Linux version, with git push-to-deploy (my favourite)

- Packer (the server), with embedded codebase (still quite simple)

- Docker (for most non-trivial deployments)

- Known Linux version, with chef or ansible (as an alternative to Docker)

- Terraform the machine, upload the codebase, run scripts on the server (ugh)

Every method had it's place, time, and reason. If possible, for simplicity, I'd go with the first option every time and then the others in that order.

The thing is, though, I may have an order of preference but that is totally overridden by the requirements of the project and whether or not the codebase is ever to be shared. For solo projects and small sites, I've not benefited from Docker as I have never had any server/OS issues (and I've been doing dev stuff for decades).

However the moment there was a need for collaborators or for pulling in extra dependencies (and here is the crunch point for me) such as headless browsers or other such 'larger' packages, then I would move on to either Packer/Terraform for fairly slow-changing deployment targets or Docker for fast-changing targets, as otherwise I inevitably started to find subtle issues creeping in over time.

In other words keep it simple while (a) you can and (b) you don't need to share code, but complexity inevitably changes things.
