dropEst | initial analysis | Genomics library

I have a little question about docker. Please understand me, I`m elementary level about docker. I'm using CentOS 7 Linux.

When I use docker (images), (espatially dropest(https://dropest.readthedocs.io/en/latest/setup.html#installation) I understand, and download image successfully with code below :

docker pull vpetukhov/dropest:latest

and get start with code below :

docker run -it vpetukhov/dropest

and copy my files to runing with dropest (Copying files from host to Docker container) with code below :

docker cp ./myfile acb889c0c379:/home/user

and running dropest(the program what I use), after running dropest, copy output files to my linux server.

docker cp acb889c0c379:~/outputFilePath/outputFile.txt ./outputFile.txt

In conclusion: docker run CONTAINER -> copy file to CONTAINER -> running program -> copy outputFile to server. I just want use 'dropest' program! there is nothing else what I want in Container.

Is there any other option? like:

[myID@server]$docker run [something option] dropest (dropest command with myFiles)(myFiles are located on server)

then obtain outputFiles on server

Please help. Best regards.
