[jankeigen]

Description:
On Kubernetes 1.21.x or OpenShift 4.12 the CronJob API moved from v1beta1 to v1. This results in an HTTP 404 when selecting the "Schedules" menu item.

Failure executing: GET at: https://172.30.0.1/apis/batch/v1beta1/namespaces/my-namespace/cronjobs. Message: the server could not find the requested resource. Received status: Status(apiVersion=v1, code=404, details=StatusDetails(causes=[], group=null, kind=null, name=null, retryAfterSeconds=null, uid=null, additionalProperties={}), kind=Status, message=the server could not find the requested resource, metadata=ListMeta(_continue=null, remainingItemCount=null, resourceVersion=null, selfLink=null, additionalProperties={}), reason=NotFound, status=Failure, additionalProperties={}).

Release versions:
2.10.3

Steps to reproduce:
Install SCDF on Kubernetes 1.21.x or OpenShift 4.12 and select the "Schedules" menu item.

Hi @jankeigen ,

This is fixed in the upcoming 2.11.0 release. We are aiming for an RC candidate w/in the next week. Feel free to try 2.11.0-SNAPSHOT from repo.spring.io until then.

Thanks

Closing in favor of spring-cloud/spring-cloud-deployer-kubernetes#529

We tried to upgrade the scdf version to solve the above issue, but its not working. I build the latest scdf version 2.11.0 with oracle dependency. I am using oracle db and the application is not able to load data from the custom datasource. Rather it tries to get from default schema. See the error below.

HI @sampathsri thanks for the report. We will prioritize looking into this. Let's track this under the other ticket you created #5497

One update on this story for someone facing this after migrating it to 2.11 in kubernetes 1.26X version . After migrating it to SCDF 2.11, the schedules page in SCDF displays the data by interacting wit openshift cron jobs api. But it wont allow you to create schedule from scdf. For this to work, we need to update the kubernetes-client to latest version . In my case, i updated it to

io.fabric8
kubernetes-client
6.9.0

Thanks for the follow up @sampathsri . I created a new issue based on your feedback. We will investigate.
