Docker-Compose重启策略 [英] Docker-Compose Restart Policy

问题描述

我看了看docker-compose的文档，发现第3版具有部署重启策略，但仅适用于群集。我尝试在服务上设置restart_policy，但出现此错误：

I looked thru the docs for docker-compose and I see that Version 3 has a deploy restart policy but it's only for swarm. I tried setting restart_policy on my service but got this error:

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

是否可以对在群集之外使用docker-compose创建的服务设置重启策略？

推荐答案

版本2使用 restart 关键字支持重新启动策略，如果不需要Swarm（您说不需要/想要），该版本应该可以正常工作。 。

Version 2 supports restart policies, using the restart keyword, and should work fine for you if you don't need Swarm (which you said you don't need/want).

version: '2'
services:
  web:
    image: apache
    restart: always

https://docs.docker.com/compose/compose-file/compose-file-v2/ #restart

复合格式版本3具有标准名为 restart_policy 的仪表，但据我所知，它仅在 deploy 的一部分中有效。仅在部署到Swarm时使用。所以版本3可能对您没有用。

Compose format version 3 has a parameter called restart_policy, but so far as I can tell from documentation it is only valid as part of deploy, which is only used when deploying to a Swarm. So version 3 is probably not useful in your case.
