【问题描述】：

Postgres 在使用 docker-compose 启动时会立即关闭。使用的yaml文件如下

version: '2'

services:   
    postgres:
        image: postgres:9.5
        container_name: local-postgres9.5
        ports:
          - "5432:5432"

docker-compose up 命令执行时的日志

当容器使用与 docker run 相同的图像启动时，Postgres 似乎工作正常

docker run --name local-postgres9.5 -p 5432:5432 postgres:9.5

【问题讨论】：

如果您的问题解决了，请与我们分享！

FWIW，看起来这是故意行为：github.com/docker-library/postgres/blob/…

您发布的日志中提到了解决方案 ----------------- local-postgres9.5 |使用“-e POSTGRES_PASSWORD=password”设置

我遇到了同样的问题，这在我尝试对数据库运行 liquibase 时有点痛苦。对我来说发生的事情是我的 liquibase 等待脚本看到数据库已启动并正在运行，因此它尝试开始运行，然后服务器像您提到的那样停止并启动，而它正在停止 liquibase 错误，因为它无法到达数据库。任何建议将不胜感激。

【参考方案1】：

我尝试了您的 docker-compose，服务似乎在容器中运行：

root@0afe99de0f0b:/# ps aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
postgres     1  0.5  0.8 227148 16128 ?        Ss   14:42   0:00 postgres
postgres    74  0.0  0.0 227148  1768 ?        Ss   14:42   0:00 postgres: checkpointer process  
postgres    75  0.0  0.0 227148  1772 ?        Ss   14:42   0:00 postgres: writer process

root        79  2.0  0.0  21820  1984 ?        Ss   14:42   0:00 /bin/bash
root        84  0.0  0.0  19092  1296 ?        R+   14:42   0:00 ps aux

无论如何，对于我的项目，我为 postgresql 使用了另一个图像：https://github.com/sameersbn/docker-postgresql。这个很好用。

【讨论】：

谢谢。你是对的 postgres 实际上正在运行。我认为由于 docker-compose 并没有超越旋转 postgres 容器，所以这是一个问题。当我使用选项 -d 时，一切似乎都正常。

如果数据目录不存在，容器运行并重启是正确的。这是因为官方图像引导程序是如何编写脚本的。更多细节在这里：***.com/questions/65417340/…

【参考方案2】：

如果您查看日志输出，则会在末尾出现以下几行：

local-postgres9.5 | server stopped
local-postgres9.5 |
local-postgres9.5 | PostgreSQL init process complete; ready for start up.

显然，停止和重新启动 Postgres 服务器是初始化过程的一部分。事实上，倒数第二行说

local-postgres9.5 | LOG:  database system is ready to accept connections.

【讨论】：

问题是它在启动、停止、启动时两次显示“数据库系统已准备好接受连接”。

【参考方案3】：

在 docker-compose.yml 中的 postgres 服务下添加密码，如屏幕截图所示。谢谢你。 click to see the screenshot

version: '3'
services:
     postgres:
          image: postgres
          environment:
              - POSTGRES_PASSWORD=postgres_password

请在您的答案中包含任何代码作为文本，这样人们可以轻松地复制和尝试。此外，这使其对搜索引擎可见，因此可以在第一时间找到。
