When you're managing distributed applications you're probably using a variety of tools that serve specific purposes. Terraform, Helm, Compose, CloudFormation, Pulumi, ARM templates, etc. No one tool solves all your needs. And new tools come along regularly. But all these tools tend to invent their own packaging.
In this talk Gareth will introduce the Cloud Native Application Bundles (CNAB) specification, and some associated tooling. CNAB embraces the multi-tool world and allows for packaging up multiple formats and their accompanying toolchains into a single artefact.
Imagine a single installable package that contains Terraform code to launch an RDS instance and a Compose file or Helm charts describing the application that will use it. Today you might package and distribute those separately, with CNAB you can keep them together. That means you can share metadata, cryptographically sign a single artefact, push all aspects of the application to a central registry and more.
In this talk you'll learn about CNAB, discuss some of the problems it solves, and see demos of the accompanying tooling.
