It’s fairly common. Although IMO the inbound traffic isn’t necessarily from “the internet”; it can be any other network. Similarly, egress refers to outbound traffic from one’s LAN/VLAN/subnet.
The term has raised in popularity ever since Kubernetes started using it in the configuration terminology. In particular, moving up from mostly exclusive to the “network administrator” role to also relevant in the “webserver operator” role.
Interesting. I wonder how much they’re motivated by fear of Tailscale, which is what I’ve been using to connect my phone to my dev servers.
Is “ingress” a common name for (what I think is) “take traffic from the Internet”?

Yes, also ngrok can restrict traffic to only allow requests that are authenticated somehow, for example.

Yes, also had been used in context with firewalls for a long time. For example the manual of OpenBSD’s pf uses it.
Also I think traffic monitoring applications, etc. use it with egress being the opposite.
The current population I think seems to come from within Google. They use it in a lot of their products (open source, cloud, etc.).
