What features are available ?

Main purpose:

  • Orchestrate workloads around a multi-node cluster

Components:

  • Controller binary is used to manage the state of the cluster, it's the only source of truth
  • Scheduler binary is used to determine the appropriate node for a workload
  • Scheduler component is able to re-scheduler a workload when a worker is unhealthy
  • Riklet binary is a worker, it receives workload from scheduler
  • Rikctl binary can be used to manage your cluster
  • Inter component communication is defined with protobuf

Workloads:

  • Workloads supported are pod and function
  • function workloads expect to be bring a custom rootfs and linux kernel in order to run
  • pod workloads are containers which support containers from hub.docker.com
