Issue with Resolving container's URL

I am using alpine based image to run my vue front end app.
I am building three services' containers using docker-compose.yml file below:
from "web", (tomcat image) I can resolve and querry the database using service name "database".
The issue is within alpine based "imbook-front" image. When I ping or curl "web" or assigned IP every thing work fine. but when I use ajax in codes, the name cant be resolved, when I use the assigned IP, the request times out. Help me if any of us knows what could be happening
