postgres:10.4-alpine database empty after Init scripts

[nurked]

Per the write-up here I should be able to extend the image to init the database on startup. No matter what I do I can't seem to be able to run this init script. According to the logs script starts and all instructions get executed, but there is nothing in the final database once I connect there.

Here is the example:

docker-compose.yaml:

services:
  nec-postgres:
    image: nec-postgres
    ports:
      - "5432:5432"
    networks:
      - smdr-network
    volumes: 
      - "pgdata:/var/lib/postgresql/data"

volumes:
  pgdata:

Dockerfile:

FROM postgres:10.4-alpine

ENV POSTGRES_USER=user
ENV POSTGRES_PASSWORD=pass
ENV POSTGRES_DB=db


COPY *.sql /docker-entrypoint-initdb.d/

One of the SQL scripts (vetted):

CREATE TABLE users(
    id                bigserial   PRIMARY KEY    NOT NULL,
    name              TEXT                       NOT NULL
);

create table account(
    id                bigserial   PRIMARY KEY    NOT NULL,
    user_id           bigserial                  NOT NULL,
    balance           numeric(15,6)             
);


ALTER TABLE account
   ADD CONSTRAINT user_id_fkey
   FOREIGN KEY (user_id)
   REFERENCES users(id);

Build happens without any problems and once I have it done I can see the startup log:

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

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:

    pg_ctl -D /var/lib/postgresql/data -l logfile start

Once you connect to the database you see empty table:

Currently I have to init the database by other means, but I wanted to be able to use docker-entrypoint-initdb.d

I'm not real experienced in SQL's but the databases in your screenshot appears to be missing the one defined from the ENV POSTGRES_DB=db and also the postgres database from the default user postgres

When I run your dockerfile everything seems correct.

$ docker run --rm -d --name postgres_test postgres_test
$ docker exec -it postgres_test bash
bash-4.4# psql -ddb -Uuser
psql (10.4)
Type "help" for help.

Ok, thank you very much @wglambert for the answer. This basically gave me a solution. It's not a postgres issue and postgres is working allright. In fact when I logged in to the container I found all of my tables without any problem.

The thing to blame is heidiSQL program which seems to be unable to display posgtres database structure properly. I connected to the container same way you did it and I was able to see the tables. Then I used pgAdmin III and despite numerous errors I was able to find all my tables.

Darn! Wasted entire day debugging things when there is nothing to debug at all.

Well, at least everything is working fine.
