Docker и Laravel. Не получается сделать миграцию: Name or service not known

Я посмотрел множество тредов с обсуждением этой проблемы, но ничего не помогло. Ошибка при выполнении команды php artisan migrate:

SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for db failed: Name or service not known (Connection: mysql, SQL: select * from information_schema.tables where table_schema = electronic_shop and table_name = migrations and table_type = 'BASE TABLE')
