I just want a glorified `autoindex on`. I don't want to manage an extra container just for that.
(I'm speaking in regards to the file viewer option, looks like there's also a file manager option on the pro version and I have a bit more mixed feeling regarding that)
There are a lot of people still doing this. Some of us have gotten away from it, but I support some people on the side that have multiple projects that still manage it this way and it works for them.
I would not want to be the one to explain to them what docker is, how it works and how to use it.
Afterwards, I just delete and that’s it.
You could use bash and be supported on almost every unix-a-like OS¹, or plain-'ol sh for even wider compatibility. You'd need to configure CGI/FCGI as well as dropping the script(s) in, but you have to do similar work for PHP/python/other if you don't already have them installed and configured for the site/directory in question.
