The problem I see is that port-forwarding happens at two levels. When you port-forward between the VM and the host, you're making any service available on the VM available on the host.
However, when you do port-forwarding between docker (i.e. docker-compose) and the VM you are making a docker service available to the VM (but not to the host!!). So I would suggest you do the following, 1. `netstat -tlpn` from within the VM. What does it say? Is AppDock and AppWin accessible from the VM? I.e. docker-compose will tell you what ports you are exporting (making available to the VM). Also notice the IP to which the port is exported. If it's 127.0.0.1 then it will not be exported beyond the VM. 2. If port 4241 and 4242 are exported to all interfaces, i.e. 0.0.0.0, then Vagrantfile should port-forward the same ports from the VM to the host. Then you should be able to access the Docker container from the host. I hope that helps.
