Major Bug Fixes

  • Fixes chaoslib task files to successfully cleanup chaos resources (daemonsets) in case of infra chaos experiments
  • Fixes chaoslib task files to end plays/experiment upon not meeting expected conditions/results rather than notify & proceed with play.
  • Move to apps/v1 for deployment/daemonset resources to support recent Kubernetes versions (1.16+)
  • Fixes inability to cleanup experiment job when .spec.jobCleanupPolicy is set to delete with Go chaos runner
  • Fixes reuse of facts/ playbook, included & registered variables by setting up a new naming convention to pass details from experiment logic playbooks to task files
  • Update the docs with correct values for Mandatory/Optional nature of experiment environmental variables
  • Fix broken/dead links on the charthub and docs
