Technical level


  • Highlight shortcomings of the current way to ship containers
  • Thinking about a standard way to ship containers
  • Introduce Nulecule, a spec to package multi container applications
  • Introduce atomicapp, a reference implementation of Nulecule spec
  • Demo atomicapp to deploy multi container applications on different providers like: openshift, kubernetes, marathon, etc


Currently there is no standard mechanism for creating, distributing and deploying applications on containers. Applications that need orchestration for multiple containers and hosts require hand-crafted customization that is difficult to replicate and manage, not to mention time-consuming. Nulecule is a specification for defining the packaged contents, including metadata, dependencies and orchestration providers, of container-based applications. Atomic App is the reference implementation of Nulecule that provides an easy method for packaging, distributing and running applications.

    Interesting talk. With all the containers talk around the world, this seems to be a topic that talks about making our life easy when it comes to using containerised applications. Would love to hear what this is all about.
