Question

我正在使用Windows docker 我的docker-compose文件如下所示：

version: '3.5'

services:
  postgres:
    container_name: postgres_container
    image: postgres
    environment:
      POSTGRES_USER: ${POSTGRES_USER:-postgres}
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD:-root}
      PGDATA: /data/postgres
    volumes:
      -  ./postgres-data:/var/
    ports:
      - "5432:5432"
    restart: unless-stopped

当我构建它时，出现以下错误日志，并且容器退出了

我检查了5432端口是否打开，并且没有进程在使用它。

当我从docker-compose.yml文件中删除卷时，它可以工作完美

我正在使用的卷。/postgres-data是我系统上的本地目录，我想将其映射到PostgreSQL容器以恢复数据库。

Answer 1

您正在Windows上使用docker，并将要在其中创建套接字（/var）的目录作为卷挂载，但Windows文件系统不支持Unix套接字。

更改配置以：

将unix套接字（/var/run/postgresql/...）留在docker中，而无需按卷安装
将数据目录作为卷安装

卷初始化时PostgreSQL在docker上不起作用
