I have a docker container that is around 160GB in size (virtual/total size).
I need to move this container to another server.
I understand that I could save the container into a docker image, copy the image into another server, then revive the container on the new server.
Considering the large size of the container, is there a way to move it to another server without having to save it to an image?
Our challenge is:
- disk space, there may not be enough space in the current server to do commit plus save the image
- down-time, would like to minimize down time while the container is committed and saved to image
Also, what’s the best way to investigate what’s the 160GB is used for in the container? i.e: is the docker framework itself use a lot of disk space?
Thank you so much in advance for any inputs.
