| QUESTION: I have a kubernetes v1.25 and i cant show the details of my cronjobs anymore on all of my namespace of my kubernetes dashboard. | |
| FYI, it works in command kubectl line i can list my cronjobs and access. | |
| Dashboard version used 2.7.0On my project i modified the api version to the one recommended : | |
| apiVersion: 'batch/v1' | |
| kind: 'CronJob'When i check the logs of my kubernetes dashboard pod, i can see that every time i try to check the details of my cronjob on a namespace through graphical dashboard, an error log pop "There was an error during transformation to sidecar selector: Resource "cronjob" is not a native sidecar resource type or is not supported".Do you have any idea ? | |
| Thank you | |
| Answer(1): There is a bug where kubernetes dashboard is using API version batchV1beta1 for cronjobs which has been removed in kuberentes version 1.25.I've created a fixed version based on kuberentes dashboard version v2.7.0. I've published it on docker hub:beffe/kubernetes-dashboard:v2.7.0-fix-cj-2You can find the code changes here:https://github.com/kubernetes/dashboard/compare/master...beffe123:kubernetes-dashboard:v2.7.0-fixes | |
| Answer(2): There might be two reasons for this issue to occur.Likeglvsaid the primary reason will be version mismatch and the bug | |
| related to that particular dashboard version. Upgrade your dashboard to | |
| the latest supported version or follow the steps provided byglv, these | |
| will help you in resolving the issue.The second issue is related to the permissions. Check whether you have | |
| provided necessary permissions to the kubernetes dashboard service | |
| account or RBAC role, assign the necessary permissions if not available | |
| it will help you in resolving these issues.Go through the logs related to kube-dashboard pods which will provide further details that will help you in diagnosing the issue more clearly. Hope this will help you | |
