Container Networking: Which One Can't Connect?
MediumDevOps10-15 minThe brief
Three containers each serve on :8080, but one of them is unreachable from anywhere — not because of a port mapping, but because it has no network at all. A capture of docker inspect for all three is at /root/project/inspect.txt (names differ per session). Find the container whose NetworkMode leaves it with no network and record its NAME (with or without the leading /) to /root/answers/net_mode.txt.
What you'll do
- Record the name of the container with no network to /root/answers/net_mode.txt
