Comment 1 Eric Paris 2014-12-15 17:17:11 UTC
cadvisor is an optional requirement. upstream they use the kubelet to launch a cadvisor pod on every node instead of having it installed on every node. I'd like to get there someday.

I'm ok making our cadvisor binary a runtime requirement for now, but I don't know if it's needed. I dropped it since cadvisor sometimes gets itself into a bit of a mess and spins at 100% cpu and we don't have the time to run that down, especially since most of kube works without cadvisor installed...

Comment 2 Jay Vyas 2014-12-15 18:56:16 UTC
in the fedora portion of the docs, it is listed as a companion that is brought in by kube. 

https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/fedora/fedora_manual_config.md

Hence at least we should update the docs.

Comment 3 Timothy St. Clair 2015-01-08 16:28:09 UTC
So cadvisor is essential for scheduling: https://github.com/GoogleCloudPlatform/kubernetes/issues/160

*required. 

Rob could please take.

Comment 4 Fedora End Of Life 2015-11-04 11:22:35 UTC
This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '21'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 21 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 5 Fedora End Of Life 2015-12-02 06:01:40 UTC
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
