The core specification is written with air-gapped environments in mind, as is the security specification. Along with covering distribution security, this specification also provides a software supply chain security model. With this specification, CNAB becomes a compelling method for transporting sophisticated cloud-native applications from network to network–without sacrificing security or requiring copious amounts of manual labor. That is the vision that CNAB relentlessly pursues. What if we just used a Docker container as the primary package technology? Send us a pull request! CNAB is designed to operate well in enterprise environments. The CNAB Claims 1.0 Specification describes how CNAB tools can share a common description of their deployed applications. But we were well aware that Helm is inextricably bound to Kubernetes. a number of issues have been raised regarding some clarifications, list of issues deferred for a post 1.0 version of the core specification. Do you have a blog post, video, tutorial, demo, or some other neat thing using CNAB that you’d like to share? You can dive right in at, . While the core cloud technologies like virtual machines and object storage have been around for over a decade, and a rich tapestry of cloud infrastructure exists, managing cloud applications remains a challenge. Why break down into multiple specifications in the first place? is supported in Porter, providing a new avenue for integrating Docker’s excellent developer tooling with other cloud technologies. We are eagerly pushing these toward completion. And the CNAB group has two more standards in flight. Finally, CNAB is a community effort, and we would like to thank everyone involved with the project! And right now, the newly released Docker Compose specification is supported in Porter, providing a new avenue for integrating Docker’s excellent developer tooling with other cloud technologies. This was the critical insight that became Cloud Native Application Bundles (CNAB). Microsoft created the Porter project. Since our initial announcement of CNAB, Docker Apps has rolled CNAB into its production release. We need to be able to describe our application as a single artifact, even when it is composed of a variety of cloud technologies; We must be able to provision our applications without having to master dozens of tools; and. With Docker, Datadog, and Pivotal (before their acquisition by VMware), we wrote a specification that described how to build cloud-centric packages that are captured in Docker containers. Late last year, the CNAB (Cloud Native Application Bundles) specification was announced - the news made it to TechCrunch and other tech publications, and partner organizations wrote about how they’re using CNAB (for example Docker, Pivotal, or Bitnami). CNAB is intended to work well in these environments as well. Make it extremely easy to use, just like a regular package manager. This specification describes how CNAB bundles (packages) are stored, discovered, downloaded, and moved. True, there are specific services (like PaaS) that make this manageable for a small segment of the ecosystem. Use and define operational verbs for lifecycle management of an app (install, upgrade, uninstall). For a list of trademarks of The Linux Foundation, please see our, Set up object storage and cloud databases databases, Load containerized workloads onto clusters like Kubernetes, but perhaps not only Kubernetes, Manage virtual networks and resources like load balancers, Interoperate with policy and identity control tools, Make it possible and even easy for developers to introduce support for new services and tools. But let’s take a step back and recap what problems CNAB is trying to solve: You can read an introduction to CNAB, and here you can find the CNAB announcement blog post. This domain was not entirely new ground for us. Docker initially announced their CNAB support for Docker Apps with, . But we wanted to make sure we did our due diligence. Initially announced at DockerCon EU in December of 2018, our combined team has continued to work on the specifications, build tools, and explore better ways of delivering an easy-to-use cloud packaging experience. The Linux Foundation has registered trademarks and uses trademarks. Sign and digitally verify a bundle, even when the underlying technology doesn’t natively support it. Whether you’re focused on running your own apps for your own cloud platform, writing applications for air-gapped networks, or planning to distribute your application to a wide variety of cloud environments, CNAB is a packaging format that can help. It is not a platform-specific tool, and developers can bundle applications targeting environments spanning IaaS (like OpenStack or Azure), container orchestrators (like Kubernetes or Nomad), container runtimes (like local Docker or ACI), and cloud platform services (like object storage or Database as a Service). Porter, on the other hand, is a user-first design. The initial security model for CNAB was designed alongside the core specification. One of those is how we install, upgrade, and delete applications in the cloud. But when it comes to a high-level solution, we are still left doing the orchestration of things either by hand or with bespoke tools. Enumerating the big features, we started to list things we would want to be able to do: The list went on in a similar vein for a while. The CNAB Claims 1.0 Specification describes how CNAB tools can share a common description of their deployed applications. Porter and Duffle already support claims, but we are excited to get a formal standard that enables information sharing across all of the tools in the CNAB ecosystem. It should be just as simple to install a distributed application into your cloud — this is the goal of the Cloud Native Application Bundles (CNAB) project. It means that you can build a bundle with tool A, install it with tool B, then upgrade it or uninstall it with tool C - so the following workflow could be possible: The arguments and flags passed to the tools above are not representative.
