Thanks In Advance

What command are you actually running? Do you have any source code like a docker-compose.yml you could add to the question? That looks like the output you get if you just run docker-compose with no arguments (not an error per se, just a long help message). — David Maze
Thanks for reply,running the application in visual studio,I am not using any comand,just clicking the run button. and docker -compose.yml file contains version: '3.4' services: homs: image: homs build: context: ./HOMS dockerfile: Dockerfile — Gopi Nath
