'Is "differentially" updating a local Docker image with the latest changes possible?
This is my first time using Docker, so excuse my potentially improper terminology. Our team uses a Docker image that contains the entire development environment, minus the git repo that needs to be cloned manually within a persistent container based on this image. The Docker image hosted on our repository is frequently updated, e.g. to include new 3rd party dependencies and other files, making my local environment - which includes a directory with the git repo where I do my work - out-of-date.
Is there a way to update my local environment with the latest image changes without having to pull the entire image with docker pull image:latest and start from scratch? Assuming there are no conflicts, I would like to preserve my local changes (git repo clone, local filesystem modifications etc.); so I'm looking for something like git pull for Docker, if that makes sense.
I must have missed something, but a search on this issue didn't yield any viable solutions.
