I have defined REACT_APP_API_URL variable in .env file its working properly in local setUp where I can fetch value in code using process.env.REACT_APP_API_URL but when I try to set this REACT_APP_API_URL from docker-yml the new value is not reflected inside code. Needed help of how to set REACT_APP_API_URL in docker-yml so that i can set different url's for our multiple setUp
