I have /var/lib/home folder in my docker container and I want to access this folder contents from my computer.
How to map this folder to host?
I'd like this folder to be writable also during usage.

You can make a persist volume in your container and the persist volume could be in your host. You can follow this link to do the persist volume.– Charles XuAug 1, 2018 at 7:31

You can make use of bind mounts
When you use a bind mount, a file or directory on the host machine is mounted into a container. The file or directory is referenced by its full or relative path on the host machine. By contrast, when you use a volume, a new directory is created within Docker’s storage directory on the host machine, and Docker manages that directory’s contents.
docker run -d \
-it \
--name bind--mount-test \
--mount type=bind,source=/path/to/host/directory/,target=/var/lib/home \
<docker image name>
bear in mind the first time when the container is created, /var/lib/home will be mounted from the host and not vice-versa
