Docker-compose MemoryError

Question

我尝试在512 Mb RAM的vps上启动odoo.我用docker.当我用普通码头工人发射容器时一切都很好.我这样推出: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,一切正常.然后我关机,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

当我启动时,我得到MemoryError:

MemoryError

我试图谷歌的原因,但找不到任何东西.

正在运行的命令缓冲json,以便它可以正确分割它.缓冲可能会消耗太多内存.

你可以试试这个:

docker-compose -f odoo.yml up -d 

这将是"超然".您仍然可以尝试运行docker-compose logs以查看日志.
