[英]How to write a shell script to checkpoint a running process in ubuntu?
CRIU or any other checkpoint/restore command cannot be used. 无法使用CRIU或任何其他检查点/恢复命令。 I need to be able to restore the process on a different system.
我需要能够在其他系统上还原该过程。
That is what CRIU should be able to do. 这就是CRIU应该能够做到的。 I mean create checkpoint and restore it at another machine.
我的意思是创建检查点并将其还原到另一台计算机上。 See CRIU documentation for container live migration:
有关容器实时迁移的信息,请参阅CRIU文档:
This is the use case from what the whole checkpoint/restore project appeared.
这是整个检查点/还原项目出现时的用例。 Container is checkpointed, then the image is copied on another box, then restored.
检查容器的位置,然后将图像复制到另一个盒子上,然后还原。 From the remote observer point of view the container is just frozen for a while.
从远程观察者的角度来看,容器只是冻结了一段时间。
It is quite challenging to write an application that migrates a process to another machine. 编写将流程迁移到另一台计算机的应用程序是非常具有挑战性的。 It would be necessary to recover process hierarchy, privileges, file descriptors, network connections, signals...
必须恢复进程层次结构,特权,文件描述符,网络连接,信号...
It is too many issues to describe in a single answer. 一个答案中描述的问题太多了。
