Since many log files shared the same format and # in order to simplify the configuration, this plugin provides a 'kubernetes' format # parser (built on top of MultilineParser). # # When tailing files, this 'kubernetes' format should be applied to the following # log file sources: # # - /var/log/kubelet.log # - /var/log/kube-proxy.log # - /var/log/kube-apiserver.log # - /var/log/kube-controller-manager.log # - /var/log/kube-scheduler.log # - /var/log/rescheduler.log # - /var/log/glbc.log # - /var/log/cluster-autoscaler.log # # Usage: # # ---- fluentd.conf ---- # # # @type tail # path ./kubelet.log # read_from_head yes # tag kubelet # # @type kubernetes # # # # ---- EOF --- require 'fluent/plugin/parser_regexp' module Fluent module Plugin class KubernetesParser < RegexpParser Fluent::Plugin.register_parser("kubernetes", self) CONF_FORMAT_FIRSTLINE = %q{/^\w\d{4}/} CONF_FORMAT1 = %q{/^(?\w)(?
