MySQL Docker Image is always restarting status

Question

I followed step by step this article ( https://www.digitalocean.com/community/tutorials/how-to-set-up-laravel-nginx-and-mysql-with-docker-compose-on-ubuntu-20-04 ).

I just changed php version (8.1) instead of (7.4) and mysql version (8.0) instead of (5.7.22)

When I run (docker ps) command, digitalocean.com/php and nginx:alpine are fine. But mysql:8.0 is always restarting status.

But I tested firstly it in local development.

When local development, everything is okay.

Buy I deployed it in the droplet, I faced the error that MySQL is always restarting status.

When I run (docker logs -f ) command, I faced the following error.

2022-08-13 06:35:20+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 8.0.30-1.el8 started.

When I run (docker run --restart=always mysql:8.0) command, I faced the following error.
