Hi all, A couple of weeks ago, at the end of the docker hackday, I demo-ed dockerlite, a re-implementation of docker with posix shell scripts, and using BTRFS instead of AUFS for images and containers storage. Dockerlite proved itself to be an incredibly useful sandbox to test new concepts. The first result is the implementation of basic docker operations using BTRFS instead of AUFS. Instead of using AUFS layers, it uses BTRFS subvolumes and snapshots. It is very efficient (since it doesn’t have to perform copy-up like AUFS) and down the road should be a more viable option than AUFS.
