Docker COPY не копирует файл?

Question

[JastaFly]

Есть Dockerfile:

FROM postgres:latest

COPY ./db_dump/my_db.dump /var/lib/postgresql/data/

CMD psql my_db < /var/lib/postgresql/data/my_db.dump

Но после окончания сборки, данного файла в указанной директории контейнера, найти не удаётся. В чём проблема?

Покажите файловую структуру и какой командой собираете. Ну и лог сборки.

[ky0]

В .dockerignore нет ничего, подходящего по описанию?

[Drno]

А направление «птички» правильно указано?

Алексей Ярков,
Данный докерфайл это часть общей сборки собираемой через docker-compose:

version: '3'

services:
  webserver:
    build:
      context: ./webserver
      dockerfile: Dockerfile
    container_name: webserver
    image: localapp/webserver
    ports:
      - "80:80"
    volumes:
      - ./code:/var/www/my-application.local
    networks:
      - app-network

  php:
    build:
      context: ./php-fpm
      dockerfile: Dockerfile
    image: localapp/php
    container_name: php
    volumes:
      - ./code:/var/www/my-application.local
    networks:
      - app-network

  pg_db:
    build:
      context: ./postgres
      dockerfile: Dockerfile
    image: postgres
    restart: always
    environment:
      POSTGRES_DB: "db_name"
      POSTGRES_USER: "db_user"
      POSTGRES_PASSWORD: "db_password"
    volumes:
      - ./postgres/data:/var/lib/postgresql/data
    ports:
      - "5432:5432"
    networks:
      - app-network

  adminer:
    image: adminer
    restart: always
    ports:
      - "8080:8080"

networks:
  app-network:
    driver: bridge

ky0, такого файла у меня вообще нет

[JastaFly]

Drno, да при чём тут птичка? Дам просто не копируется в контейнер, так что в какую сторону не верти птичку результат будет всегда один
