SQLSTATE[HY000] [2002] Connection refused laravel docker

I am trying to migrate my database. Giving this error.

I got in docker this error:

Error starting userland proxy: listen tcp4 0.0.0.0:3306: bind: address already in use

Then I kill this port:

sudo kill `sudo lsof -t -i:3306``

Now, I am using this port to connect my db:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=inventory
DB_USERNAME=root
DB_PASSWORD=root

docker-compose.yml

database:
    image: mysql:5.7.22
    restart: always
    container_name: mysql-database
    command: mysqld --sql_mode=""
    volumes:
      - "./data/db:/var/lib/mysql"
    environment:
      MYSQL_DATABASE: ${MYSQL_DATABASE}
      MYSQL_USER: root
      MYSQL_PASSWORD: 123456
      MYSQL_ROOT_PASSWORD: root
    ports:
      - 3306:3306
    networks:
      - development_network

Now, how can I solve this problem?
