There is a working example for nginx/yii/php-fpm in Docker?

I am using this image yiisoftware/yii2-php:7.4-fpm and 2 days looking for a working example. Does it even work? I'm stuck on mistakes:

[error] 21#21: *45 connect() failed (111: Connection refused) while connecting to upstream, client [error] 21#21: *44 no live upstreams while connecting to upstream, client
