How to solve problem with empty docker-entrypoint-initdb.d? (PostgresQL + Docker) - postgresql

Question

Here is a part of my project structure:
Here is a part of my docker-compose.yml file:
Here is my Dockerfile (which is inside postgres-passport folder):
I have init.sql script which should create user, database and tables (user and db are the same as in docker-compose.yml file)
But when I look into my docker-entrypoint-initdb.d folder it is empty (there is no init.sql file). I use this command:
docker exec latest_postgres-passport_1 ls -l
docker-entrypoint-initdb.d/
On my server (Ubuntu) I see:
I need your help, what am I doing wrong? (how can I copy a folder with init.sql script. Postgres tell me that
/usr/local/bin/docker-entrypoint.sh: ignoring
/docker-entrypoint-initdb.d/*
(as he can't find this folder)
All code in text format below:

Answer 1

In your docker-compose.yml file, you say in part:
postgres-passport:
image: postgres:latest
volumes:
- "./postgres-passport:/docker-entrypoint-initdb.d"
- "./data/postgres_passport_data:/var/lib/postgresql/data"
So you're running the stock postgres image (the Dockerfile you show never gets called); and whatever's in your local postgres-passport directory, starting from the same directory as the docker-compose.yml file, appears as the /docker-entrypoint-initdb.d directory inside the container.
In the directory tree you show, if you
cd deploy/latest
docker-compose up
The ./postgres-passport is expected to be in the deploy/latest tree. Since it's not actually there, Docker doesn't complain, but just creates it as an empty directory.
If you're just trying to inject this configuration file, using a volume is a reasonable way to do it; you don't need the Dockerfile. However, you need to give the correct path to the directory you're trying to mount into the container.
postgres-passport:
image: postgres:latest
volumes:
# vvv Change this path vvv
- "../../postgres-passport/docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d"
- "./data/postgres_passport_data:/var/lib/postgresql/data"
If you want to use that Dockerfile instead, you need to tell Docker Compose to build the custom image instead of using the standard one. Since you're building the init file into the image, you don't also need a bind-mount of the same file.
postgres-passport:
build: ../../postgres-passport
volumes:
# Only this one
- "./data/postgres_passport_data:/var/lib/postgresql/data"
(You will also need to adjust the COPY statement to match the path layout; just copying the entire local docker-entrypoint-initdb.d directory into the image is probably the most straightforward thing.)
