Docker undo rm container

I accidentally removed my container with "docker rm [CONTAINER_ID]".

Is there anyway that I can undo this, or restore the data in the container?

It was a CentOS image.

Similar question: how to retrieve volume from a removed Docker container?

The above question is asking how to retrieve data from a "data volume container", but my one was not. I stored everything inside the CentOS image.

The answer is probably no.

According to the comment I received from docker forum:

docker rm is just like rm on the host, there is no going back

Personal story: I lost 3 weeks of my business data, and having big trouble with it. Good lesson to teach myself that never "rm" unless you are 100% sure what you are doing, and backup your data!
