How to pass arguments to entrypoint in docker-compose yml

Question

I use this image  dperson samba  The image is defining it s own entrypoint and I do not want to override it   I need to pass arguments to the entrypoint  easy with docker only   docker run     dperson samba arg1 arg2 arg3   But how to do it with docker compose yml    Right now I use as a workaround    command  samba sh arg1 arg2 arg3   But it is not satisfying as I force the redefinition of the entrypoint

You can use docker-compose run instead of docker-compose up and tack the arguments on the end  For example   docker-compose run dperson samba arg1 arg2 arg3   If you need to connect to other docker containers  use can use --service-ports option   docker-compose run --service-ports dperson samba arg1 arg2 arg3

Whatever is specified in the command in docker-compose yml should get appended to the entrypoint defined in the Dockerfile  provided entrypoint is defined in exec form in the Dockerfile   If the EntryPoint is defined in shell form  then any CMD arguments will be ignored
