Creating Postgresql database with dummy data using docker compose - postgresql

Question

I created a docker compose file for implementing Postgresql database wih pgAdmin.
version: "3.8"
services:
# environnement postgresql
postgresdb:
image: postgres
container_name: postgres
restart: always
user: root
environment:
POSTGRES_USER: root
POSTGRES_PASSWORD: root
APP_DB_USER: docker
APP_DB_PASS: docker
APP_DB_NAME: org_db
networks:
- postgres-network
ports:
- '5432:5432'
expose:
- '5432'
volumes:
- ./data/dbstore/postgres/postgres:/var/lib/postgresql/data
- ./data/setup/postgres:/docker-entrypoint-initdb.d
pgAdmin:
image: dpage/pgadmin4
container_name: pgAdmin
restart: always
user: root
links:
- postgresdb
depends_on:
- postgresdb
networks:
- postgres-network
environment:
PGADMIN_DEFAULT_EMAIL: root#root.com
PGADMIN_DEFAULT_PASSWORD: root
ports:
- "5050:80"
volumes:
- ./data/dbstore/postgres/pgadmin:/var/lib/pgadmin4/storage
- ./data/setup/postgres/pgadmin4.db:/pgadmin4.db
entrypoint: /bin/sh -c "cp /pgadmin4.db /var/lib/pgadmin4/storage/pgadmin4.db && cd /pgadmin4 && /entrypoint.sh"
When running the docker compose up command, the applications are correctly launched. My issue is that at the same time I'm trying to create a database with sample data.
After some researches (a response was found here: https://graspingtech.com/docker-compose-postgresql), I created a sh file:
#!/bin/bash
set -e
export PGPASSWORD=$POSTGRES_PASSWORD;
psql -v ON_ERROR_STOP=1 --username "$POSTGRES_USER" --dbname "$POSTGRES_DB" <<-EOSQL
CREATE USER $APP_DB_USER WITH PASSWORD '$APP_DB_PASS';
CREATE DATABASE $APP_DB_NAME;
GRANT ALL PRIVILEGES ON DATABASE $APP_DB_NAME TO $APP_DB_USER;
\connect $APP_DB_NAME $APP_DB_USER
BEGIN;
CREATE TABLE IF NOT EXISTS employee (
id serial primary key,
name varchar(250) NOT NULL,
age int NOT NULL,
salary numeric NOT NULL,
PRIMARY KEY (id)
);
INSERT INTO employee(ID,NAME,AGE,SALARY) values (1,'Dave',30,90000),(2,'Peter',28,80000);
COMMIT;
EOSQL
