Kubernetes FluxCD Helm Health

The k8s-fluxcd-helm-health codebundle checks for helm related resources within the Kubernetes cluster to surface up potential issues.

TaskSet

This TaskSet looks for any helmreleases in the specified namespace within the configured context and:

  • prints a list of every helmrelease and it's status
  • prints a list of all helm release version details
  • prints a list of helm releases that have mismatched versions (e.g. last attempted version doesn't match the running version)
  • prints all helmreleases that are not healthy along with the associated error messages

Example configuration:

DISTRIBUTION=Kubernetes
CONTEXT=sandbox-cluster-1
NAMESPACE=vault
RESOURCE_NAME=helmreleases

With the example above, the TaskSet will collect the above mentioned data from the vault namespace in the sandbox-cluster-1 cluster for the resources with a shortname of helmreleases.

Requirements

  • A kubeconfig with get permissions to on the objects/namespaces that are involved in the query.

TODO

  • Add additional rbac and kubectl resources and use cases
  • Add an SLI for measuing helmrelease health
  • Add additional troubleshooting tasks as use cases evolve
