如何指定要在docker-compose版本3中使用的容器运行时? [英] How can I specify the container runtime to use in docker-compose version 3?

问题描述

我正在一个需要nvidia运行时的容器上工作.我可以在v2.3 docker-compose文件中指定此运行时，如下所示:

I'm working on a container that requires the nvidia runtime. I can specify this runtime in a v2.3 docker-compose file like so:

version: "2.3"
services:
  my-service:
    image: "my-image"
    runtime: "nvidia"
    ...

运行 docker-compose up my-service 效果很好.我得到了nvidia运行时，一切正常.

Running docker-compose up my-service works just fine. I get the nvidia runtime and everything works fine.

我只是通过将"2.3"更改为"3"来尝试此操作，当我执行 docker-compose up my-service 时，出现以下错误:

I've tried this just by changing the "2.3" to "3" and I get the following error when I do docker-compose up my-service:

ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for services.my-service: 'runtime'

如果我删除了 runtime:"nvidia" 行，这将毫无问题地出现-除非它不使用nvidia，而且我需要访问主机上的GPU才能获得性能想要.

If I take out the runtime: "nvidia" line, this comes up without problems—except of course it's not using nvidia and I need access to the GPU on the host to get the performance I want.

docker-compose v3中的 runtime 是否等效?如果没有，为什么放弃该选项?提前致谢.:)

Is there an equivalent for runtime in docker-compose v3? If not, why was this option dropped? Thanks in advance. :)

推荐答案

我意识到这个问题比较老，但是昨天我碰到了这个问题.

I realize this question is rather old but I ran into it yesterday.

TL; DR:将您的docker-compose升级到1.27.0 +

TL;DR : Upgrade you docker-compose to 1.27.0+

详细信息

关于专用Docker错误线程中 runtime 关键字的删除已有相当多的讨论:

There has been quite a discussion about the removal of the runtime keyword in the dedicated Docker bug thread : https://github.com/docker/compose/issues/6691

最后，在1.27.0中，Docker决定允许它返回.因此，您只需要拥有正确版本的docker-compose.

Finally, in the 1.27.0, Docker has decided to allow it back. So you just need to have the correct version of docker-compose.

我建议使用pip安装路径，因为它们的版本是最新的(Debian buster中的当前docker-compose版本为1.21).似乎还有其他好的原因为此，请参见此处.

I would recommend the pip install path as their versions are more up to date (current docker-compose version in Debian buster is 1.21). And it seems there are other good reasons to do so, see here.
