- umoci: a New Tool for OCI Images Aleksa Sarai, 29 November 2016.
Very recently, I've been working on implementing the required tooling for creating and modifying Open Container Initiative images without needing any external components. The tool I've written is called

umociwhen it comes to SUSE tooling like the Open Build Service or KIWI is what really makes it exciting.
