Docker-compose MemoryError

我尝试使用512 Mb RAM在vps上启动odoo。我使用码头。当我用普通码头工具启动容器时，一切都很好。我发动这样的： Postgres的容器：Docker-compose MemoryError

docker run -d -e POSTGRES_USER=odoo -e POSTGRES_PASSWORD=odoo --name db postgres

odoo容器：

docker run -p 8069:8069 --name odoo --link db:db -t odoo

没有错误，一切工作正常。然后我关机，删除此容器和尝试做同样的事情泊坞窗 - 撰写：

app: 
    image: odoo 
    tty: true 
    ports: 
     - "8069:8069" 
    volumes: 
     - ./addons:/mnt/extra-addons:ro,Z 
    links: 
     - db:db 

db: 
    image: postgres 
    environment: 
     POSTGRES_USER: odoo 
     POSTGRES_PASSWORD: odoo

当我启动我得到的MemoryError：

我想谷歌的原因，但couldn”找不到任何东西。

的内存错误是从'搬运工-compose'，而不是你的应用程序来。也许512MB不足以运行compose＆postgres。 – johnharris85

@ johnharris85似乎是正确的。我已经在我的机器上运行了你的命令，它运行良好。我认为你只需要给postgres足够的内存来处理，或者配置它的参数来尝试使用更少的内存（这在我看来是不行的，512mb对于db实例来说听起来不够记忆） –

在我的本地机器上，docker-compose也可以创建容器。但我想如果普通码头工人可以一个一个地创建容器，为什么码头工人可以不能？此外，我后来与安装的应用程序一起工作，添加了一些模块，所以数据库工作正常，并没有收到任何错误。我通过普通的docker运行容器之后。 –
