PostgreSQL not creating tables when running on docker - postgresql

Question

I am trying to run PostgreSQL on a linux container docker in my Windows server, but when I run it, it creates database, but there is no table and no data in it, while it should create all tables and add datas to it using that Actibook_latest.sql
Here's the code of Dockerfile
# Dockerfile
FROM postgres:9.4
RUN mkdir -p /tmp/psql_data/
COPY Actibook_latest.sql /tmp/psql_data/
COPY init_docker_postgres.sh /docker-entrypoint-initdb.d/
EXPOSE 5432
Here's the code of init_docker_postgres.sh
#!/bin/bash
# this script is run when the docker container is built
# it imports the base database structure and create the database for the tests
DATABASE_NAME="postgres"
DB_DUMP_LOCATION="/tmp/psql_data/Actibook_latest.sql"
echo "*** CREATING DATABASE ***"
psql "$DATABASE_NAME" < "$DB_DUMP_LOCATION";
echo "*** DATABASE CREATED! ***"
And here's the code of docker-compose
version: '2'
services:
db:
build: '.\Main Database Backup'
environment:
POSTGRES_DB: ${DB_POSTGRES_APP_DATABASE}
POSTGRES_USER: ${DB_POSTGRES_APP_USER}
POSTGRES_PASSWORD: ${DB_POSTGRES_APP_PASSW}
PGDATA: /var/lib/postgresql/data/pgdata
ports:
- "5432:5432"
restart: unless-stopped
Main Database Backup is the folder that contains that Dockerfile and init_docker_postgres.sh. Also that Actibook_latest.sql contains sql to create the tables, data, etc.
And when I run docker-compose up while other serives go up and running, here's what it shows to logs:

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
postgres -D /var/lib/postgresql/data/pgdata
or
pg_ctl -D /var/lib/postgresql/data/pgdata -l logfile start

I'm thinking that there might be a firewall issue since its running perfectly in other servers that I have, the problem appears only in this one. So is that any chance that postgresql in this machine is preventing it?
Update
I tried to restart docker and then used these commands:
docker rm $(docker ps -a -q)
docker rmi $(docker images -a -q)
docker volume rm $(docker volume ls -q)
now its showing this error:
/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/init_docker_postgres.sh
*** CREATING DATABASE ***
: No such file or directory/init_docker_postgres.sh: line 4: /tmp/psql_data/Actibook_latest.sql
/docker-entrypoint-initdb.d/init_docker_postgres.sh: line 4: $'\r': command not found
*** DATABASE CREATED! ***
and when I go to docker to check for file:
docker exec -it db bin
cd /tmp/psql_data
ls
it shows that there exists Actibook_latest.sql

Answer 1

It seems that your entrypoint init script was not working, make sure data_volume is empty before run your container.
This is because in docker-entrypoint.sh, at line 57, it checks your data volume, if it exists, it won't execute your init scrip.
