  • Pruning elastics with Kubernetes CronJobs

    Pruning elastics with Kubernetes CronJobs

    There was a time you just ran ‘crontab -e’ to make this happen. But, progress, are you still on my lawn? Lets discuss how to solve the specific issue of ‘my database fills up my disk’ in a Cloud Native way. So the situation.

Looking back in on them it seems that they are somehow anti-inflationary. The selling (well asking!) price of a cryptocat has gone up by about the same amount (expressed in…
