具有 docker 所有权问题的 PostgreSQL

Question

从昨天开始，我尝试在 Windows (Bootcamp MacBook Pro) 上启动我的 docker 项目，我只剩下一个问题:PostgreSQL 图像。

错误信息:

postgres_1         | This user must also own the server process.

我到处搜索，尝试了一切，仍然有这个问题......

我试过的是:

• 使用 docker volume create --name postgres -d local 创建 docker volume 并在我的 docker-compose.yml 中使用它

docker-compose.yml

version: '2'

services:
  postgres:
    image: postgres:latest
    ports:
      - "5432:5432"
    volumes:
      - postgres:/var/lib/postgresql/data

  networks:
    internal_ip:
      ipv4_address: 192.168.1.2

  volumes:
    postgres:
      external: true

• 直接在 docker compose 中添加卷

体积样本

volumes:
  postgres:
    driver: local

• 使用相对或绝对 Windows 路径
• 为不同的 PostgreSQL 文件夹(conf、data…)声明多个卷

我尝试 docker compose down，重启电脑，删除图像，没有任何变化，同样的错误。

我已经在 Docker 设置中选中了共享驱动器框。

有没有人是可行的解决方案？我会继续让它发挥作用，如果我发现了什么，我会更新帖子。

提前致谢。

当我尝试为 PostgreSQL 数据使用卷时，我终于弄清楚出了什么问题。

我不知道我们使用了 docker-compose.override.yml，它声明了一个带有 Windows 路径的卷。

所以这是一个在 Docker for Windows 上使用 PostgreSQL 的工作解决方案，具有持久数据:

version: '2'

services:
  postgres:
    image: postgres:11.5
    ports:
      - 5432:5432
    volumes: 
      - pgdata:/var/lib/postgresql/data
      - pgconf:/etc/postgresql
      - pglog:/var/log/postgresql

volumes:
  pgdata:
    driver: local
  pgconf:
    driver: local
  pglog: 
    driver: local
