Lens extension, which helps to debug pods
This extension is useful for interactive troubleshooting when kubectl exec is insufficient because a container has crashed or a container image doesn't include debugging utilities, such as with distroless images.
This extension adds new menu items to Pods in Workload -> Pods table The menu includes the next subitems:
| SubItem | Description |
|---|---|
| Run as debug pod | Creates and runs new Pod based on with <current_pod>_debug name and placed on the same node/namespace. The Pod is deleted automatically after session closing |
| Run as ephemeral image | Attaches and runs ephemeral image to the selected Pod. If the Pod contains 2+ containers you can select which will be linked with an ephemeral container. Warning! Be sure that the current cluster supports this feature |
The extension adds 3 parameters in File -> Preferences Debug Image: default image, which will be used for ephemeral containers and debug pods, possible values:
| Name | Description | Link |
|---|---|---|
| busybox | Default value | https://hub.docker.com/_/busybox |
| markeijsermans/debug | https://hub.docker.com/r/markeijsermans/debug | |
| praqma/network-multitool | https://hub.docker.com/r/praqma/network-multitool |
Show all debug images in context menu: shows all debug images as context menu for operation
Use ephemeral containers: Just hides/shows subitems related to ephemeral containers for each cluster
