 If you need to transfer files with push/pull/install, the adb process will not have access to the host
 filesystem, so it might be better to install the package android-tools-adb with apt.
 The IP address of each VM is in ./libs/vms/{vm_id}/ip

+-- Installing an apk through Docker and vm-adb
+If for some reason you have troubles using the regular adb commands, you can use docker to transfer files to the VM, through the aic.adb container.
+```
+$ docker cp path/to/file.apk kpbmvzpw_adb:/tmp/
+$
+```
+Then you can install an apk on the VM, using the vm-adb install command :
+```
+./bin/vm-adb kpbmvzpw install /tmp/file.apk
+```
