Docker-Compose + Postgres：/docker-entrypoint-initdb.d/init.sql：权限被拒绝

Question

我有以下 docker compose 文件：

version: "3"
services:
  postgres:
    image: postgres:11.2-alpine
    environment:
      POSTGRES_PASSWORD: root
      POSTGRES_USER: root
    ports:
      - "5432:5432"
    volumes:
      - ./init-db/init-db.sql:/docker-entrypoint-initdb.d/init.sql

这是 init-db.sql：

version: "3"
services:
  postgres:
    image: postgres:11.2-alpine
    environment:
      POSTGRES_PASSWORD: root
      POSTGRES_USER: root
    ports:
      - "5432:5432"
    volumes:
      - ./init-db/init-db.sql:/docker-entrypoint-initdb.d/init.sql

当我运行时docker-compose up，我收到此错误：

server started
/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/init.sql
/docker-entrypoint-initdb.d/init.sql: Permission denied

我已经尝试过：

• chmod 777 在 sql 文件中
• chmod -x 在 sql 文件中
• 运行 docker 和 docker-compose 使用 sudo

任何的想法？

Answer 1

我尝试使用以下撰写文件，它似乎按预期工作。您确定您使用的文件的路径吗？

version: "3"
services:
  postgres:
    image: postgres:11.2-alpine
    environment:
      POSTGRES_PASSWORD: root
      POSTGRES_USER: root
    ports:
      - "5432:5432"
    volumes:
      - ./init-db.sql:/docker-entrypoint-initdb.d/init.sql
