Docker compose - fixes to volume will be created as root user by default, and run docker container as desired user

https://stackoverflow.com/questions/56844746/how-to-set-uid-and-gid-in-docker-compose

In Docker-compose.yml

add user (So created volume will be your current user and group, and docker container will be run as specified user and group as well).

// It's a good idea to not use system variable UID and GID as UID is read only and bash will produce an error UID: readonly variable to terminate script execution 

// https://serverfault.com/questions/259843/bash-script-error-test-line-5-uid-readonly-variable

..

servuces:

    app:

         user: "${uID}:${gID}"    

.....

        volumes:

            - ./app:/app

***** 

********export GID and UID before docker compose cmd or set in bash_profile so they are available for your session *** man id to see that -u is effective user id and -g is effective group id

export uID="$(id -u)" 

export gID="$(id -g)"

:wq!

source .bash_profile or relogin if not working
