Question

当使用docker-compose启动时，Postgres会立即关闭。使用的yaml文件位于

之下

version: '2'

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

执行docker-compose up命令时的日志

当使用与docker run

相同的图像启动容器时，Postgres似乎工作正常

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

Answer 1

如果查看日志输出，则会在结尾显示以下行：

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

显然，停止并重新启动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.

Answer 2

我尝试了你的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

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，我使用另一个图像作为postgresql：https://github.com/sameersbn/docker-postgresql。这个工作正常。

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

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

当使用docker-compose启动时，Postgres会立即关闭
