localhost not working even though Docker shown running

Hi All,

I am an new user of Laravel 8 and recently applied Docker for installation

Docker-desktop shown example-apps of Laravel are running normally

But open in browser of containers / apps of Docker triggered webpages of localhost for each application as belows:

1. localhost: 6397 for redis shown : This page isn’t working

2.localhost: 3306 for mysql shown: This page isn’t working

3.localhost:1025 for mailhog shown: This page isn't working

1. localhost:7700 for meilisearch shown: welcome to MeiliSearch (i.e. I think that it is normal)

5.localhost:80 shown: Webpage of Laravel (i.e. I think that it is normal)

Also I have run sail test and shown Tests : 2 passed

Would you be kind enough to advise what I can do for the above problem ?

Thank you for your kind attention

Andrew
