failed to connect to 'host.docker.internal:5555': Connection refused for Dynamic Analysis with AVD

boulwabd commented 6 hours ago

ENVIRONMENT

OS and Version: Ubuntu 20.04.5 LTS 
Python Version: Python 3.8.10
MobSF Version:  Mobile Security Framework v4.0.7
Docker Version: Docker version 27.3.1, build ce12230

EXPLANATION OF THE ISSUE

Connection to host.docker.internal:5555 refused when trying to start dynamic analysis with "--add-host=host.docker.internal:host-gateway" specified at startup.

STEPS TO REPRODUCE THE ISSUE

1. Start emulator "emulator -avd android28 -writable-system -no-snapshot -no-window -id emulator-5554"
2. Running docker with "sudo docker run -it --rm -p 8000:8000 -p 1337:1337 -e MOBSF_ANALYZER_IDENTIFIER=emulator-5554 --add-host=host.docker.internal:host-gateway opensecurity/mobile-security-framework-mobsf:latest"
3. Navigating to dynamic analysis page causes "failed to connect to 'host.docker.internal:5555': Connection refused"

I have verified the emulator is running and can manually run "/usr/bin/adb -s host.docker.internal:5555 shell getprop ro.build.version.release" after adding host.docker.internal to my /etc/hosts file but this step fails inside the container. 

This is my containers hosts file:
127.0.0.1       localhost
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.1      host.docker.internal
172.17.0.2      83be5dfcd65e

Was searching through existing issues before posting but did not realize this situation was covered in the FAQ. I believe the problem is Docker CE cannot talk to localhost. Running the docker in the host network was the workaround for my case.
