在Docker-Composose开始时，Postgres立即closures

在Docker-Composose开始时，Postgres立即closures。 下面是使用的yaml文件

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Docker运行一个容器开始使用相同的图像时，Postgres似乎工作正常

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

Answer 1

我试过你的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 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 postgres 76 0.0 0.0 227148 1768 ?

无论如何，对于我的项目，我使用postgresql的另一个图像： https ： //github.com/sameersbn/docker-postgresql 。 这个工作正常。

Answer 2

如果你看看你的日志输出，最后会出现以下几行：

 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.
