限制 docker-compose v3 中的资源 [英] Limit resources in docker-compose v3

问题描述

docker-compose.yml 文件的第 3 版不再支持 mem_limit.文档告诉我应该使用 deploy.resources 键代替，而且这部分只对 swarm 或 docker stack 有效.

mem_limit is no longer supported in version 3 of docker-compose.yml file. The documentation tells that I should use the deploy.resources key instead but also that this part will only be effective with swarm or docker stack.

cpu_shares、cpu_quota、cpuset、mem_limit、memswap_limit:这些已经被deploy 下的resources key 替换了.注意，deploy 配置只在使用 docker stack deploy 时生效，被 docker-compose 忽略.

cpu_shares, cpu_quota, cpuset, mem_limit, memswap_limit: These have been replaced by the resources key under deploy. Note that deploy configuration only takes effect when using docker stack deploy, and is ignored by docker-compose.

... 如所写文档.

如何使用 yml 文件的 v3 格式使用 docker-compose 设置内存/cpu 限制?

How do I set memory/cpu limits with docker-compose with v3 format of the yml file?

推荐答案

我也在想同样的事情，结果发现:https://github.com/docker/compose/issues/4513

I was wondering the same thing and found this: https://github.com/docker/compose/issues/4513

简而言之，这是不可能的，您必须使用 docker-compose 格式的 2.1 版才能指定docker-compose up

So in short it's just not possible to do that, you have to use the version 2.1 of the docker-compose format to be able to specify limits that are not ignored by docker-compose up
