Docker-compose MemoryError

我嘗試使用512 Mb RAM在vps上啓動odoo。我使用碼頭。當我用普通碼頭工具啓動容器時，一切都很好。我發動這樣的： 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

沒有錯誤，一切工作正常。然後我關機，刪除此容器和嘗試做同樣的事情泊塢窗 - 撰寫：

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

當我啓動我得到的MemoryError：

我想谷歌的原因，但couldn」找不到任何東西。

的內存錯誤是從'搬運工-compose'，而不是你的應用程序來。也許512MB不足以運行compose＆postgres。 – johnharris85

@ johnharris85似乎是正確的。我已經在我的機器上運行了你的命令，它運行良好。我認爲你只需要給postgres足夠的內存來處理，或者配置它的參數來嘗試使用更少的內存（這在我看來是不行的，512mb對於db實例來說聽起來不夠記憶） –

在我的本地機器上，docker-compose也可以創建容器。但我想如果普通碼頭工人可以一個一個地創建容器，爲什麼碼頭工人可以不能？此外，我後來與安裝的應用程序一起工作，添加了一些模塊，所以數據庫工作正常，並沒有收到任何錯誤。我通過普通的docker運行容器之後。 –
