重启后 - docker-compose 抛出 OOM-Killer

After Reboot - docker-compose is throwing OOM-Killer

我有一台单板机运行。 (1GByte - RAM) 我通过 Docker 组合文件启动了 11 个不同的 Docker 容器,这成功了! 要清楚。我可以随时 docker-撰写 - docker-撰写。没问题。


这是 docker 统计信息 概览名称已替换为 xxx

有人可以向我解释为什么我在重启时出现内存错误,而在我刚启动时却没有 docker-up

我自己发现了问题。 在我的 Docker 撰写文件中,我通过“depends_on”指定了容器的顺序。这个命令让我的记忆无法一下子填满。然而,在 reboot/crash 之后,“restart:always” 函数启动并同时启动所有 11 个容器。

注意:作为 docker-compose,我还使用了一个 docker 容器(aarch64 - 问题),这可能会导致这个问题。
