A simple page that lists all the CronJobs that are available in K8s Cluster
Often in Kubernetes cluster developers deploy CronJobs and forgets that. To kepp a track of the deployed CronJobs and its corresponding schedules, they need to run the kubectl get cronjobs -o custom-columns=JOB:metadata.name,SCHEDULE:spec.schedule command. This is ok most of the times, but to keep a track of the timetables, it would be great to see these information in the table format on demand.
This small utility program provides the CronJob listing along with the schedules in a HTML page.
By default, the cronjobs are listed within the current namespace. To get the cluster wide list, pass cluster string in env variable SCOPE. Also pass the go-html-template path in TMPL_FILE_PATH variable. A sample html template can be found here.
Values passed to the html template will construct a page as shown below.
The page pops-up with the link for the schedule to Crontab Guru with the exact schedule for easier understanding.
A helm-chart for this is available here.
