Goals

• Discuss running and defining applications in Kubernetes (e.g., APIs, SDKs, Controllers, package management tools, etc.)
• Work on improvements to the Workload API
• Suggest Kubernetes features where we see friction
• Be the voice of the people running applications in Kubernetes (developers and devops)
• Help people get involved in the Kubernetes community
• Show early features/demos of tools that make running apps easier

Non-goals

• Do not endorse one particular ecosystem tool
• Do not pick which apps to run on top of Kubernetes
• Do not recommend one way to do things (e.g., picking a template language)

Helm and Charts

Helm, Charts and its other subprojects have moved to the CNCF . See Helm’s community repository for information about the Helm project.
