Question

我需要使用PostgreSQL创建一个容器，并且我有一个文件init.sql，其中包含数据库的结构，最后是一个从CSV复制数据的命令。

我的init.sql是：

CREATE SEQUENCE aditivo_id_seq;

CREATE TABLE public.aditivo
(
   id               BIGINT NOT NULL DEFAULT nextval ('aditivo_id_seq'::regclass),
   clasificacion    CHARACTER VARYING (200) NOT NULL,
   descripcion      CHARACTER VARYING (4000) NOT NULL,
   id_aditivo       CHARACTER VARYING (10) NOT NULL,
   nombre           CHARACTER VARYING (200) NOT NULL,
   origen           CHARACTER VARYING (40) NOT NULL,
   peligro          CHARACTER VARYING (200) NOT NULL,
   CONSTRAINT aditivo_pkey PRIMARY KEY (id)
      NOT DEFERRABLE INITIALLY IMMEDIATE,
   CONSTRAINT uk_c1t6nik8nbqfei52k7rlo28lv UNIQUE (id_aditivo)
      NOT DEFERRABLE INITIALLY IMMEDIATE
);

COPY aditivo (clasificacion, descripcion, id_aditivo, nombre, origen, peligro) FROM '/var/lib/postgresql/csvs/aditivos.csv' DELIMITER ',' CSV HEADER;

我的docker-compose.yml是：

version: "3.3"
services:
  postgreSQL:
    restart: on-failure
    image: postgres:latest
    volumes:
      - ./postgres/aditivos.csv:/var/lib/postgresql/csvs
      - ./postgres/init.sql:/docker-entrypoint-initdb.d/init.sql
    environment:
      POSTGRES_USER: UALappDitivos
      POSTGRES_PASSWORD: TFGappDitivosUAL!
      POSTGRES_DB: db
    ports:
      - "5432:5432"

可以很好地复制init.sql，但不能复制csv。

我得到了错误：

psql:/docker-entrypoint-initdb.d/init.sql:147: ERROR: could not open file "/var/lib/postgresql/csvs/user.csv" for reading: Not a directory

我该如何正确执行此操作？

要解决此问题，我复制文件夹而不是复制file.csv。所以我的docker-compose.yml看起来像：

version: "3.3"
services:
  postgreSQL:
    restart: on-failure
    image: postgres:latest
    volumes:
      - ./init.sql:/docker-entrypoint-initdb.d/init.sql
      - ./postgres/csvs:/var/lib/postgresql/csvs
    environment:
      POSTGRES_USER: UALappDitivos
      POSTGRES_PASSWORD: TFGappDitivosUAL!
      POSTGRES_DB: db
    ports:
      - "5432:5432"
  rest:
    build: rest
    restart: on-failure
    depends_on: 
      - postgreSQL
    ports:
      - "8080:8080"

将csv复制到容器中以在init.sql中使用
