KMON

Kubernetes administrators swiss knife. Kmon will automate boring, frequently performed tasks in Kubernetes.
Some examples:

• create a pod using a specified PVC to check its content
• create a pod with a PVC restored from a specific VolumeSnapshot
• create a PVC from VolumeSnapshot
• and the list goes on...

Kmon can be used as a standalone CLI tool, like any other. But its true power comes from integration with k9s as a k9s plugin

Usage

Standalone CLI tool

• POD modes kmon pod:
  • Create a pod from PVC --mode run-from-pvc
  • Create a pod with a PVC restored from VolumeSnapshot --mode run-from-snapshot
    • --mount-path string mount path (default "kmon-mnt")
    • --name string pod name (default "kmon-pod")
    • --pvc-name string pvc name (default "kmon-pvc")
    • --snapshot-name string snapshot name (default "kmon-snapshot")
    • --volume-name string volume name (default "kmon-volume")
    • --context string kubeconfig context to use
    • -n, --namespace string namespace to run in (default "default")
• PVC modes kmon pvc
  • Create VolumeSnapshot from PVC --mode snapshot-from-pvc
    • --name string pvc name (default "kmon-pvc")
    • --snapshot-class-name string snapshot class name
    • --snapshot-name string snapshot name (default "kmon-snap")
    • --source-pvc-name string source pvc name

K9s plugin

To configure kmon as a k9s plugin, check out k9s-plugin.yaml for reference

K8s CronJob

kmon potentially can be used to automate repetitive tasks, like creating VolumeSnapshots on a schedule using CronJob for example.

TBD

• Import AWS Volume Snapshot into K8s VolumeSnapshot - for situations when we're copying volumes across regions for example.
• Delete the existing PVC and replace it with another one with the same name, using VolumeSnapsthot to restore data and restart workloads.
• Discover pods and send http requests to all of them at once - for troubleshooting data propagation on distributed systems for example.
• If there is anything else you think it would be useful, feel free to create an issue with a feature request or create a PR.
