Carvel Sets Sail for the CNCF Sandbox

We’re excited to announce the Cloud Native Computing Foundation (CNCF) accepted Carvel as a Sandbox project on September 13, 2022. This occasion marks a major milestone for Carvel, and the Carvel project team is incredibly honored to join the ranks of other awesome VMware-originated projects, such as Antrea, Contour and Harbor.

The project team looks forward to Carvel’s new home in CNCF’s vendor-neutral environment and receiving guidance from CNCF as the project continues to grow within the open source ecosystem. The team is also hoping to grow the contributor community and seeks additional maintainers. The donation will open more opportunities to collaborate with other open source projects within CNCF.

Carvel’s origin

Carvel was born from Dmitriy Kalinin and Nima Kaviani’s frustration with existing tools to deploy Kubernetes workloads. With a UNIX philosophy in mind, they built k14s (“Kubernetes Tools”) – ytt, kbld, kapp, kwt – as simple and composable tools for application development. Dmitriy and Nima released the tools as they were developed, from fall of 2018 to spring 2019. K14s became popular in June 2019 and were rebranded to Carvel in August 2020. “Carvel” was chosen by the project team because the imagery of workers using the Carvel technique of boat building – where the planks of the hull are laid side-by-side without an overlap to create a smooth surface and a robust frame – reminded them of how their tools can combine with UNIX pipes.

Carvel today

Carvel provides a set of reliable, single-purpose, composable tools that aid in application building, configuration and deployment to Kubernetes.

Developers working with Kubernetes face challenges with packaging and distributing software. A core goal of Carvel is to automate the installation and management of software on Kubernetes, while paving a smooth path to getting code to production. Following the Unix principle of a collection of tools, each “doing one thing well,” the Carvel project hosts a set of tools (imgpkg, kapp, kapp-controller, kbld, secretgen-controller, vendir, ytt), allowing users to use them in combination with each other as well as with other tools in the broader cloud native ecosystem.

Navigating the journey

Achieving each milestone of Carvel’s journey would not be possible without the support and contributions of its incredible community. The project team expresses gratitude to the following individuals:

Not interested in becoming a contributor but want to join the Carvel community? Here are other ways you can get involved (all subject to change as the team begins the migrating/onboarding process into CNCF):

  • Join Carvel’s slack channel, #carvel in Kubernetes workspace and connect with more than 1,000 Carvel users.
  • Find the project on GitHub. Suggest how the team can improve the project or the docs or share any other feedback.
  • Attend Carvel Community Meetings! Check out the Community page for full details on how to attend.

What’s next

In the coming months, the project team will be adding features and functionality to further improve the development and delivery of applications on Kubernetes. They’d like to hear from the wider CNCF community about what problems they’re trying to solve and how Carvel can help.

With the introduction of Carvel into the CNCF Sandbox and the ongoing support of the community, the team is excited for the possibilities ahead!
