localhost/127.0.0.1 resolves to Docker Desktop host with --network host
Actual behavior
localhost/127.0.0.1 does not resolve to Docker Desktop host with --network host
host.docker.internal does resolve to Docker Desktop host with --network host
Information
Linux distro: Ubuntu
Distro version: 22.04.1 LTS
Docker Desktop Version: 4.12.0 (85629)
I've been having this problem for a while now, so isn't version-specific AFAIK. I am aware Docker Desktop runs a Linux VM, so (I think) --network host is resolving to the VM network instead of the host OS network. I was under the impression that this should work after reading this blog post - specifically:
Seamless plumbing into the host OS giving containers access to the filesystem and networking
or I might just be missing something fundamental. 😅
Steps to reproduce the behavior
python -m http.server 8080
docker run --rm --network host alpine sh -c 'apk add curl -q && curl -sv -o /dev/null http://localhost:8080'
