问题描述
我有一台单板计算机正在运行.(1GB-RAM)我通过一个Docker compose文件启动了11个不同的Docker容器，并且可以正常工作！要清楚.我可以docker-compose down-docker-compose up在任何时候.没问题.
I have a single board computer running. (1GByte - RAM)I started 11 different Docker containers via a Docker compose file and this worked!To be clear. I can docker-compose down - docker-compose up at any time. No Problem.
这是 docker stats ，用于用xxx代替的概述名称
This is the docker stats for overview names replaced with xxx

现在，我添加了一个重启策略(始终为OR，除非已停止)
Now i added a restart-policy (always OR unless-stopped)
但是，当我的设备重启时，我收到以下错误消息.
However, I get the following error message when my device reboots.

有人可以向我解释为什么重启时会出现内存错误，而我刚启动docker-up却无法得到
推荐答案
我自己发现了问题.在我的Docker compose文件中，我通过"depends_on"指定了容器的顺序.这个命令阻止了我的记忆立刻被填满.然而，在重新启动/崩溃之后，重新启动:总是"被重新启动.功能启动并立即启动所有11个容器.
I found the problem myself.In my Docker compose file, I specified an order of containers via "depends_on". This order prevented my memory from filling up at once. However, after a reboot/crash the "restart:always" function kicked in and started all 11 containers at once.
注意:在docker-compose中，我还使用了一个docker容器(aarch64-问题)，这可能会导致此问题.
Note: As docker-compose I also used a docker container (aarch64 - problems) which could possibly lead to this problem.
这篇关于重启后-docker-compose抛出OOM-Killer的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
