if your goal is to run the docker exec with a specific user inside of the container, you can use the --user option.

docker exec --user myuser container-name [... your command here]

If you want to run gosu every time, you can specify that as the command with docker exec

docke exec container-name gosu 1000:1000 [your actual command here]

in my experience, the best way to encapsulate this into something easily re-usable is with a .sh script (or .cmd file in windows).

drop this into a file in your local folder... maybe gs for example.

#! /bin/sh
docker exec container-name gosu 1000:1000 "$@"

give it execute permissions with chmod +x gs and then run it with ./gs from the local folder
