Bita as a container update
Is there any chance to implent this within the container enviroment?
No container expert here. What's missing to achieve what you want?
The same functionality but with container images
Not sure what you're after but running bita inside a container should be no different than running it on a host. And using bita to transfer container images (if the image is a file) should be no different than any using it to transfer any other file.
What im saying is doing the whole process of update based on one base container image and his next version, and apply the changes on tje container image files. Something like balenaEngine does and CargoSync.
Yeah, that's what bita does - Delta update of a file from one version to another. It doesn't care what kind of file it is, container image or what else, though it may work more or less efficient depending on the file content.
