Issue #19350 has been reported by Kyle Harper. ---------------------------------------- Feature #19350: Stateful Cleanup Messages https://projects.puppetlabs.com/issues/19350
Author: Kyle Harper Status: Unreviewed Priority: Normal Assignee: Category: Target version: Affected Puppet version: Keywords: Branch: Synopsis: When a resource is removed from a manifest, it remains on the target nodes. Puppet should be aware of superfluous items that it has managed in the past, and take actions accordingly to help ensure stateful correctness (aka: leave it the way you found it). Cause for Request: Cruft can be as detrimental to a server's stability as a missing file. Puppet is fantastic about making sure things exist; but it doesn't ever 'look behind' to see if it's left a trail of cruft. There are two situations where cruft can come into existence: 1. Human Error I work on a module or node definition. Some resources are defined, let's say some files. I later update the module to put the files somewhere else. I forget to go clean up the original files on all my nodes. I now have superfluous files that might be innocuous, or they could be a problem. Regardless, asking a human to forward-think all these changes is the antithesis of what an automated tool like puppet could be able to achieve. 2. Silent Content Creation I work on a module or node definition. I create a resource, we'll say a cron entry. I notice I misspelled "dailyy_backup". I change it to "daily_backup" not realizing an agent already ran and has a cron entry now. When it runs again, there will be two cron entries for my daily backup, and I won't know it. My Request: Allow puppet to, at a minimum, compare its current manifest for a node with previous manifests for that node. If a resource was previously defined but is no longer managed AND still exists on a node: alert me to a possible clean-up. I can then take those alerts and either use puppet to ensure => absent on them or simply remove the target resources manually. The end goal here is to help make puppet do what it does even better: automate configuration and remove human error. -- You have received this notification because you have either subscribed to it, or are involved in it.
