Docker tmpfs removes all data when containers are down

Question

I added tmpfs to my docker-compose.yml file in Laravel, and whenever a run "sail up" command, my databases start empty. Is there anyway to avoid that and keep my databases with tables and data. My docker file is:

version: '3'
services:
    laravel.test:
        build:
            context: ./vendor/laravel/sail/runtimes/8.2
            dockerfile: Dockerfile
            args:
                WWWGROUP: '${WWWGROUP}'
        image: sail-8.2/app
        extra_hosts:
            - 'host.docker.internal:host-gateway'
        ports:
            - '${APP_PORT:-80}:80'
            - '${VITE_PORT:-5173}:${VITE_PORT:-5173}'
        environment:
            WWWUSER: '${WWWUSER}'
            LARAVEL_SAIL: 1
            XDEBUG_MODE: '${SAIL_XDEBUG_MODE:-off}'
            XDEBUG_CONFIG: '${SAIL_XDEBUG_CONFIG:-client_host=host.docker.internal}'
        volumes:
            - '.:/var/www/html'
        networks:
            - sail
        depends_on:
            - mysql
            - mailhog
    mysql:
        image: 'mysql/mysql-server:8.0'
        ports:
            - '${FORWARD_DB_PORT:-3306}:3306'
        environment:
            MYSQL_ROOT_PASSWORD: '${DB_PASSWORD}'
            MYSQL_ROOT_HOST: "%"
            MYSQL_DATABASE: '${DB_DATABASE}'
            MYSQL_USER: '${DB_USERNAME}'
            MYSQL_PASSWORD: '${DB_PASSWORD}'
            MYSQL_ALLOW_EMPTY_PASSWORD: 1
        tmpfs:
            - /var/lib/mysql
        volumes:
            - 'sail-mysql:/var/lib/mysql'
            - './docker/mysql/create-database.sh:/docker-entrypoint-initdb.d/10-create-testing-database.sh'
        networks:
            - sail
        healthcheck:
            test: ["CMD", "mysqladmin", "ping", "-p${DB_PASSWORD}"]
            retries: 3
            timeout: 5s
    mailhog:
        image: 'mailhog/mailhog:latest'
        ports:
            - '${FORWARD_MAILHOG_PORT:-1025}:1025'
            - '${FORWARD_MAILHOG_DASHBOARD_PORT:-8025}:8025'
        networks:
            - sail

    sail:
        driver: bridge

    sail-mysql:
        driver: local

Thanks in advance.
