PHP files downloading when using php-fpm and nginx with Docker

I already saw other posts here about a similar issue, but I think mine needs a different solution because the other posts didn't help.

I am running two separate containers with Docker: For php-fpm and for nginx. When I try to display text using index.html file it's all ok, but when I change the file name to index.php it downloads a "download" file instead.

I'm not sure if it's only because of my

Self-hosted DDNS as part of a consumer product offering (potentially >>1000 sub-subdomains), how?

I'm developing a product that enables users to run a service at home which is part of a larger network. This service needs to be contacted regularly by a coordination service running in the cloud (on a VPS). The mechanism implemented for this relies on a normal port-forward on the user's internet-facing router, but also needs a reliable way to be found: enter DDNS.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
