@kamal-github: Try to remove data volume for postgres data and up your container again.
Not working for me either, my docker-compose file looks like this. I see that file present in docker-entrypoint-initdb.d but I think its is not executing it.
postgres:
image: onjin/alpine-postgres:9.5
restart: unless-stopped
volumes:
- ./init.sql:/docker-entrypoint-initdb.d/1-init.sql
ports:

getting same error as @g-bastianelli . I am on windows 8.1 using docker toolbox and getting this:
psql:/docker-entrypoint-initdb.d/init.sql:0: could not read from input file: Is a directory
I have windows 10 and i am using postgresql 10.3 image and also get this message
/usr/local/bin/docker-entrypoint.sh: ignoring /docker-entrypoint-initdb.d/*
here my compose file
version: '2' services: gateway-postgresql: image: postgres:10.3 volumes: - ./postgres-init/:/docker-entrypoint-initdb.d/ #also tried - ./postgres-init:/docker-entrypoint-initdb.d environment: - POSTGRES_MULTIPLE_DATABASES=db1,db2 - POSTGRES_USER=abc - POSTGRES_PASSWORD=abc ports: - 5432:5432
I have folder postgres-init/initdb.sh
Ordering the scripts alphabetically works but there are a few caveats. If you are ordering using numbers be aware that if you have more than 9 files then the script name that begins with 10 is executed before the script whose name begins with 1
the thing here is that no mather what we have in docker-entrypoint-initdb.d in my case a single file called init,sh, seems that all are ignored there.
My docker-compose.yaml file looks like this below. I've tried all combinations of possible configurations.
volumes:
- ./dumps:/docker-entrypoint-initdb.d/dumps
- ./dumps/portal.sql:/docker-entrypoint-initdb.d/portal.sql
- ./dumps:/docker-entrypoint-initdb.d/dumps.sql
And ./dumps contains portal.sql. However, I get this error: /usr/local/bin/docker-entrypoint.sh: ignoring /docker-entrypoint-initdb.d/dumps
I am following the directions, so what gives?
UPDATE: I got it to work!
Here is what works:
volumes:
- ./dumps/portal2.sql:/docker-entrypoint-initdb.d/1-portal.sql
...
volumes:
dumps:
This works. Apparently you have to have a subdirectory which you make a volume down below and then your scripts sit in it and can link as volumes directly inside the service.
@poloche make sure you aren't setting the PGDATABASE environment variable. I had a script that created this database, but got an error that the database didn't exist before the init scripts had a chance to run
I was facing the same issue of init scripts getting ignored.
I HAVE FOUND A SOLUTION if it helps anyone !!

Now as you can see I have postgres-data: volume mounted.
If i remove this directory before starting docker-compose file things work !!.
I that directory/volume is present the init scripts are ignored !!
enjoy!!
init scripts are run when there postgres-data folder is created. If the postgres-data folder is initialized, the init scripts will be ignored.

@rjurney are you sure that is the reason? I wouldn't think a top-level named volume would have anything to do with a local folder. Does anyone know?

nice caveat, thanks
I'm running into an issue where my db init process is in fact running in the container, at least batching a bunch of CREATES and INSERTS of my dump data, but then is abruptly shut down and restarted.

@honestcomrade did you manage to fix this?
@honestcomrade any luck?

I had the same issue but after a few hours of trying, I found a working combination of docker-compose and init script. Btw, I read here that the container shutting down and restarting is (apparently) part of the initialization process.

@Juliannnnshipit this looks like it might help me out, thanks a bunch for the reply.
Hi there! Thank you! Is there way to update my sql script and then update existing image, without data loss? for example I need to add trigger for existing postgres image...

Hi, initdb.sh scripts are called only if there is no database set, so if you need to migrate current database it's better to run this sql migrations from psql cli for already created databases, and initdb.sh/ scripts will be run for new clean instances.
FYI: do not pass the host (localhost) in the initialization script or you'll likely to encounter an error about not being able to connect to database.
in docker-compose.yml
patch /file.sql:/patch/to/docker-entrypoint-initdb.d/
in fact, point the file to the directory
hint: remember where the work dir is base on your docker file for the image you are using to compose this container
volumes:
- ./init.sql:/docker-entrypoint-initdb.d/
did anyone get this to work properly. i am currently facing similar issues
it is easier to make a docker file and COPY the init.sql to /docker-entrypoint-initdb.d
did anyone get this to work properly. i am currently facing similar issues
well what i did which worked was that i deleted all previous containers of the same image.
docker rm -f -v postgres_container_name.
restarted and it worked like a charm after that
What is the best way to add tables from sql files after the first init?
at the moment i have a docker compose file with mariadb und phpmyadmin
docker-entrypoint-initdb.d works the first time
but i need the possibilty to creates tables from sql files after docker-compose up
can you help me?
after init, I'm using a separate file with database migrations (using app specific db migrations system) and run them by application entrypoint.sh, from time to time then I merge migrations to init, and clear migrations file.
I had some trouble getting it to work. My docker-compose.yml looks like this:
volumes:
- ./:/app
services:
db:
image: postgres:12
restart: unless-stopped
volumes:
- ./project/data/init.sql:/docker-entrypoint-initdb.d/init.sql
- postgres_data:/var/lib/postgresql/data/
environment:
- POSTGRES_USER=picker
- POSTGRES_PASSWORD=#
- POSTGRES_DB=pricepicker-v2
volumes:
postgres_data:This is because Postgres does not execute init scripts if postgres-data folder is present. So I just renamed it to postgres and it works like a charm!
Thanks @Juliannnnshipit for your help. I got it working.

#!/usr/bin/env bash

Thank you so much. It saved my time
I struggled with this same issue and thought the only solution was to not use a sql file in the docker-entrypoint-initdb.d directory but actually the only problem was that I wasn't granting pivs to my user i was logging in as so the schemas were getting created just invisible to my user...
Don't have to do this
#!/bin/bash
psql -v ON_ERROR_STOP=1 --username "$POSTGRES_USER" -d "$POSTGRES_DB" <<-EOSQL

You can do this...

If you put a CREATE DATABASE statement at the top of your actual SQL script, but don't supply POSTGRES_DB, it will use the POSETGRES_USER as the DB name so the tables don't go where they should.
If you supply both POSTGRES_DB and put a CREATE DATABASE statement at the top of the SQL script, you will get an error about the DB already existing since POSTGRES_DB will create the DB before the script runs. You can see this order of operations in the logs.
I think the real fix here is to:
- set POSTGRES_DB to be the name of the DB you want to create and don't CREATE TABLE in your script
- Add SQL scripts to volume per docs

In my case file is copied, but sql file is not executed? what is the config required for running it too.
