I had a number of great conversations on @cnab_spec while at #KubeCon. On the flight home I've written up what it's all about https://www.morethanseven.net/2018/12/15/what-is-cnab/ …

Thanks for the writeup, Gareth. How does this compare with Docker Application Bundles, App Registry, Nulecule, and/or Elasticbox?

Doesn't seem especially cloud native. (1) Imperative. (2) Obscures but doesn't abstract the deployment environment. (3) Ditto for the deployment tools, which all have very different upgrade behaviors. (4) Lacks observability. (5) Not GitOps friendly.

I do understand the goal of deployment tool interoperability, though. CI tools/systems have a similar challenge. For instance, Jenkins plugins are coupled to Jenkins.

I'd say CNAB is much more general, while all of these focused on a specific tool (say Kubernetes or Compose) and/or implementation. You can also see it as a generalisation of things like Helm. Or MSI for API-driven infrastructure
Thanks. Twitter will use this to make your timeline better. UndoUndo
