How to connect and use remote interpreter in docker container on the target?

Running remotely works perfectly without a docker container on the remote. One problem is the deployment path is wrong and cannot be changed. Try to select the docker dir and it shows prohibited.

This is what I get when trying to run it on the target. For one where is this pointing to??? local/target/in or out of docker?

/usr/bin/python3 /opt/project/gpu_test.py 
/usr/bin/python3: can't open file '/opt/project/gpu_test.py': [Errno 2] No such file or directory

The deployment path is outside of docker on the target, mappings will not allow it to go into docker.

Would you please point me to the instructions that clearly show how to connect to a docker on the remote target.

Not sure where it even came up with the /opt path???
