docker-compose.yml is not working

[sheraliinamdar]

docker compose is using the script version 3 and it is using older version constructs like "depends_on"
using few latest version construct like "start_period". Please remediate depends_on construct with respect to latest version docker script.

start_period appears to only modify the healthcheck parameter.

depends_on appears to be part of the latest spec. See https://docs.docker.com/compose/compose-file/05-services/#depends_on
