Docker-compose postgreSQL权限错误

Question

我对 docker-compose postgreSQL 有问题，我正在 Windows WSL 2 + Docker Desktop 上工作。当我在 Linux 服务器上运行 docker-compose 时，它​​运行良好，但是当我尝试在本地启动它时，我收到下一个错误：

postgres      | chmod: changing permissions of '/var/lib/postgresql/data': Operation not permitted
ngnix         | 10-listen-on-ipv6-by-default.sh: info: /etc/nginx/conf.d/default.conf is not a file or does not exist
postgres      | The files belonging to this database system will be owned by user "postgres".
postgres      | This user must also own the server process.
postgres      |
postgres      | The database cluster will be initialized with locale "en_US.utf8".
postgres      | The default database encoding has accordingly been set to "UTF8".
postgres      | The default text search configuration will be set to "english".
postgres      |

ngnix         | /docker-entrypoint.sh: Configuration complete; ready for start up
postgres exited with code 1

我尝试更改所有项目的权限，如下 =>chmod 777 -R project_folder

Dcoker-compose.yml：

postgresdb:
    container_name: postgres
    build:
      context: ./docker/postgres
      dockerfile: Dockerfile
    environment:
      - POSTGRES_PASSWORD=password123
    volumes:
    - ./docker/postgres/init.sql:/docker-entrypoint-initdb.d/init.sql
    - ./postgres-data:/var/lib/postgresql/data

    ports:
    - "5432:5432"

没有想法，如何解决。请帮帮我！

所以我的猜测是，由于您将相对于 docker-compose 文件的目录安装为 WSL 中的“数据”目录，因此会发生权限错误。您可以尝试修复这些权限（chmod、chown 等本地目录）。

您还可以使用“命名”卷- 这也应该消除权限问题。

# docker-compose.yml

services:
  # ...
  db:
    image: postgres:latest
    volumes:
      - "dbdata:/var/lib/postgresql/data"

volumes:
  dbdata:
