Hi i am new to docker.

I have cloned my laravel code from

https://github.com/laravel/laravel/tree/8.x

and followed the steps provided in given below link.

https://www.digitalocean.com/community/tutorials/how-to-set-up-laravel-nginx-and-mysql-with-docker-compose

But still, mbstring is not installed in my project with php 8 version as my laravel project is compatible with a higher version than 7.2 but when i tried mbstring with 7.2 version it was easyly installed. i want to install mbstring with php 8 version.

Given below is my docker file. please have a look at it.

Try this..

What follows is more appropriate as a comment, but I have an insufficient reputation to comment.

Adarsh Hiwrale’s excellent suggestion mostly worked for me, but I had to rearrange a few lines to avoid a race condition.

That is, the reordered lines are necessary for anyone starting from scratch who is building for the first time because they will not yet have a partial Docker build that can execute RUN php artisan key:generate.

My revision follows with comments indicating what was modified and why.
