The kubernetes plugin is extremely slow when run on a cluster with thousands of namespace
Last modified: 2017-09-27 06:19:58 EDT
Description of problem:
The kubernetes plugin is extremely slow when run on a cluster with thousands of namespaces. This is the result of multiple kubectl commands being executed per project. There should be a way to supress this behavior.
See https://github.com/sosreport/sos/pull/1068 for a solution of this which adds a new option to the kubernetes module to suppress this behavior.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
kubernetes plugin takes a long time to complete when running a sosreport.
expect to be able to suppress some of this behavior that allows the sosreport to run in a reasonable time.
The pull request for this is already in progress: if anything, I am considering flipping the default (so that all namespaces will _not_ be collected by default - i.e. the user has to enable an option in order to get the current behaviour).
This will mean that associates will need to request the "all namespaces" option when appropriate but this seems a preferable user experience to defaulting to collecting this - on systems with many namespaces where sos is being run for an unrelated problem this would be quite irritating.
(based on prior experience, users will not learn to add '-k kubernetes.no_individual' until they have at least one bad experience with the default behaviour).
That sounds like a good idea to me. Once a solution is in place, if it changes any support workflows, I can modify our docs.
