A lot of companies are unsure which solution to choose and many may not be aware of Docker Swarm as an alternative to Kubernetes. One thing that many Sysadmins find is that Docker Swarm is simply easier, quicker to setup and maintain by far than Kubernetes.........
Partclone is a great tool that is basically like dd only it does not waste space, it doesn't take the whole partition, yet it does the same thing as dd, only with huge space/cost savings.
Clonezilla uses partclone and is more of an integrated/easy to use suite I guess you could say. I've personally only used partclone but I wish there was an easy way to mount partclone images.
I believe with Clonezilla you can do that, so I will probably give it a shot next time.........
