I’m in the tutorial and I ran this command while on a public WiFi:
docker run -dp 3000:3000 getting-started
Immediately after running it, this pops up:
I click Cancel because I can’t tell what com.docker.backend.exe is trying to do… does someone know?
It may be that it’s just trying to go through port 3000 and that’s when Windows Firewall sees it and pops up the prompt… the issue is, because nothing is telling me EXACTLY why it’s popping up, I don’t know if it’s actually for that port from that command or for some other port for some other thing docker is doing. Can someone clarify?
UPDATE: When I check Windows Firewall for apps it allows, it shows two entries for com.docker.backend, where the 1st entry is checked (enabled) with Private checked (enabled), and the 2nd is unchecked (disabled) with Public checked (enabled)… so the firewall allows docker through Private, but I still can’t tell what for, and clicking Details doesn’t specify any ports on either, so I just cannot tell what docker wants through the firewall.
