sealer Roadmap

Improve the basic capabilities of the Sealer Image

• Multi-architecture/hybrid architecture support
• Easy-to-use image caching capabilities with no intrusion
• Provide better Sealer Image collaboration mechanisms
  • open the Sealer Image Repo project
  • contains most of the common open source middleware and kxs runtime(not provided by the Sealer community)

Focus the core of distributed application definition

• Keep exploring reducing complexity of k8s-based distributed application definition
• Support the full life cycle management of application and decoupled from the kxs runtime
• Support more built-in application types
  • contains common application types including helm chart, kube resource, OAM, etc
  • provide extensibility, supports user-defined extended app types
• Support ClusterImage on more heterogeneous infrastucture:
  • general OS and arch
  • general existing Kubernetes

Build stable and easy-to-use cluster delivery capabilities

• support for large-scale cluster life cycle management, such as 3K nodes
• support for managed existing clusters
• support more kxs runtime support, such as k8s, k0s, k3s, etc
• support IAAS diagnostic capabilities, provider cluster pre-installation check tools

Sealer spec Definition Stabilization

• Kubefile stabilization
• Clusterfile stabilization
• ClusterImage spec stabilization
  • define Kubernetes part and application part separately
  • protocol stabilization among sealer binary, basefs and cluster instance

Performance Improvement

• Improve Sealer Image distribution efficiency as possible
• Improves sealer build efficiency as possible through caching and other capabilities
• Improve cluster bootstrap efficiency as possible
