docker alpine postgres in compose not executing docker-entrypoint-initdb.d scripts - postgresql

Question

When using the https://github.com/kiasaki/docker-alpine-postgres image in docker compose, the scripts inside /docker-entrypoint.initdb.d are not being executed as I view from the logs:
db_1 | LOG: database system was shut down at 2016-09-05 18:16:02 UTC
db_1 | LOG: MultiXact member wraparound protections are now enabled
db_1 | LOG: database system is ready to accept connections
db_1 | LOG: autovacuum launcher started
The thing is, if I build the Dockerfile standalone and run the container, it will execute the sql files inside the folder, like you can see from the logs:
waiting for server to start....LOG: database system was shut down at 2016-09-05 18:28:18 UTC

The docker-compose.yml:
version: '2'
services:
db:
build: ./db
environment:
- POSTGRES_PASSWORD=testpass
restart: always
app:
build: ./app
ports:
- "5000:5000"
volumes:
- .:/app/src
depends_on:
- db
environment:
- DB_SERVER=postgres://postgres:testpass#db:5432/postgres
What am I doing wrong here?

UPDATED as he use his own Dockerfile, not from the github link.
Could you proide the docker run command so that if I build the Dockerfile standalone and run the container, it will execute the sql files inside the folder. You should mount some directory to the container so it can find the SQL files.
I read the Dockerfile at https://github.com/kiasaki/docker-alpine-postgres/blob/master/Dockerfile and asked myself where are the SQL files? It just make the directory without copy SQL files
mkdir /docker-entrypoint-initdb.d
Then, in the docker-entrypoint.sh, it check if there's any SQL file to execute
for f in /docker-entrypoint-initdb.d/*; do
case "$f" in
*.sh) echo "$0: running $f"; . "$f" ;;
*.sql) echo "$0: running $f"; psql --username "$POSTGRES_USER" --dbname "$POSTGRES_DB" < "$f" && echo ;;
*) echo "$0: ignoring $f" ;;
esac
echo
done
I think we should mount a SQL directory, like
version: '2'
services:
db:
build: ./db
environment:
- POSTGRES_PASSWORD=testpass
restart: always
entrypoint:
- docker-entrypoint.sh
volumes:
- ./docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d
- ./docker-entrypoint.sh:/docker-entrypoint.sh
