Docker-compose MemoryError

Question

我试着用512MB的内存在vps上启动odoo。我用docker。当我用普通的docker启动容器时，一切都很好。我是这样启动的: postgres容器：

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。然后我关闭，删除这个容器，并尝试用docker-compose做同样的事情：

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

当我启动的时候，我得到了MemoryError：

MemoryError

我试着用谷歌搜索原因，但什么也找不到。

Answer 1

正在运行的命令对json进行缓冲，以便它可以正确地拆分它。可能是缓冲占用了太多的内存。

你可以试着这样做：

docker-compose -f odoo.yml up -d 

这将运行"detached“。您仍然可以尝试运行docker-compose logs来查看日志。

Answer 2

您可以尝试在odoo.yml中删除tty:true。
