What happened:

I'm creating a deploy in AWS with lambda for set the images in Kubernetes Cluster.

I want set image in CronJob:

Cron:

NAME                                SCHEDULE      SUSPEND   ACTIVE  
LAST SCHEDULE   AGE cronjob.batch/analytics-staging-0   */5 * * * *

Python Code:

 def set_image_job(image, namespace, name, conn):
     api_instance = conn.BatchV1beta1Api()

     body = {
         "spec": {
             "template": {
                 "spec": {
                     "containers": [
                         {
                             "image": image
                         }
                     ]
                 }
             }
         }
     }

     try:
         response = api_instance.patch_namespaced_cron_job(name, namespace, body, pretty=True)
         print(response)
     except Exception as e:
         print("Exception when calling BatchV2alpha1Api->patch_namespaced_cron_job: %s\n" % e)
if __name__ == "__main__":
     conn = get_connection_eks()
     eks_resource = EKSResources('staging-app', conn)
     jobs = eks_resource.get_cron_jobs()
     for item in jobs:
         set_image_job('accountid.dkr.ecr.eu-west-1.amazonaws.com/app:latest',
 'staging-app', item, conn)

Note: item = analytics-staging-0

The response is ok, but don't change the image.

Can you help me?

Thanks!
