Imaging I have 100 servers which already installed our OS environment (centos6 and many many private tools and libraries which could only used in our company), and I want to install glusterfs on the 100 servers. Is there a way for me to build my docker image base on my company’s OS environtment? I don’t want to build a docker image which contains all my company’s private tools and libraries, as it will be too large.
I have tried to build this image by:
FROM scratch VOLUME / / #something for installing glusterfs
The ‘VOLUME / /’ means map the root directory of my OS directly into the container, but it does not work.
