In pike gems are installed from upstream([1]). Since this is failing after 19th, on 19th there are new releases for fluent-plugin-kubernetes_metadata_filter, Those must have the issue, Last known good release is fluent-plugin-kubernetes_metadata_filter:1.0.1.

Also noticed in queens/master these gems are installed from RPM, so not having this issue:

[1] https://github.com/openstack/kolla/blob/stable/pike/docker/fluentd/Dockerfile.j2
[2] https://github.com/openstack/kolla/commit/ee127b9e76c6e0673ab183bba9b27302645d2b27

Forgot to add link for new releases on 19th April:- https://rubygems.org/gems/fluent-plugin-kubernetes_metadata_filter/versions

Proposed Review in Kolla stable/pike:- https://review.openstack.org/#/c/563657/

[Richard Megginson (rmeggins)]

In order to support ruby 2.0 and fluentd 0.12, you need to change the gem install to use

     'fluent-plugin-kubernetes_metadata_filter:<2' \

Otherwise you'll get the 2.0 version which requires ruby 2.4 and fluentd 1.0

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/kolla 5.0.3 release.
