SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for database failed: Temporary failure in name resolution (SQL: select * from information_schema.tables where table_schema = chatapp and table_name = migrations and table_type = 'BASE TABLE') about laravel-complete-dockerization HOT 2 OPEN

I ran into a similar issue. The error I was getting was:
could not find driver (SQL: select * from information_schema.tables where table_schema = chatapp and table_name = migrations and table_type = 'BASE TABLE')

When I looked at the php.ini files, I realized there were 2:
php.ini-development php.ini-production

I updated APP_ENV in .env from =local to =development, helping get me past my error. I'll let you know if I find anything related to your error, but I wanted to share what I know.
