[Feature] Group license supports docker

[jondy]

The idea is

1. Register physical device (offline) as group device
2. In physical device (offline), start daemon pyarmor-docker, listen on 127.0.0.1 to serve docker auth request
3. In docker container, visit network host.docker.internal to request host auth

Refer to how to talk to a service on localhost within docker container

Docker Desktop 18.03+ for Windows and Mac supports host.docker.internal as a functioning alias for localhost. Use this string inside your containers to access your host machine.

Docker Engine users on Linux can enable host.docker.internal too via the --add-host flag for docker run. Start your containers with this flag to expose the host string:

docker run -d --add-host host.docker.internal:host-gateway my-container:latest

This feature is developing now, the current solution is that register each docker as one device.

Keep the docker with same name, same network and same harddisk, the same device file should work.

The idea is that generate regfile for each host device, then run the following command in the host

$ pyarmor reg pyarmor-device-regfile-xxxx.1.zip
$ python -m pyarmor.cli.docker
listen docker auth request on 172.2.0.1:29092

Then run container with --add-host in Linux:

docker run -d --add-host host.docker.internal:host-gateway my-container:latest

And run the following commands inside the container

pyarmor reg pyarmor-device-regfile-xxxx.1.zip
pyarmor gen foo.py

It has been implemented in Pyarmor 8.2.8, refer to
