WARNING: this version requires Cilium to run because of the dependency on the CiliumNetworkPolicy CRD

  • Upgrade dependency chart to 9.2.0.
  • Adjusted the resource and limits to accomodate larger clusters by default
  • Adjusted the admission controller to give it more QPS against the API
  • Adjusted the updater to give it more QPS against the API
  • Adjusted the recommender to give it
    • more QPS against the API
    • doubling the memory in case of an OOMKilled event
    • Using the 95% percentile for the calculation of the CPU usage: should allow to scale up more precisely to account for spikes in CPU consumption of the workload
    • Adjusted the resource and limits to accomodate larger clusters by default
    • Calculating recommendations only for workloads which do have a VPA custom resource, instead of all workloads
    • Removed standard network policies to decrease maintenance burden
    • Fixed Cilium Network Policy to allow CRD jobs execution
    • Added Cilium Network Policy weight for an early execution
    • Disabled VPA for the updater pod otherwise it keeps on getting re-scheduled because the memory consumption varies a lot between reconsiling resources and idle
    • Disabled VPA for the recommender pod otherwise it keeps on getting re-scheduled because the memory consumption varies a lot between reconsiling resources and idle
