https://docs.fluentd.org/configuration/config-file Since v1.8.0, helper methods use_nil and use_default are available. But we are using fluentd (1.7.4) Can you please set CLO to unmanaged and then edit the fluent configuration to replace 'use_nil' with 'nil' unquoted to see if it resolves the issue. I would like to add a proper test but need to understand how to setup ssl first @jeff, the nil doesn't work. It popup the error below. $ oc logs fluentd-2zvll Setting each total_size_limit for 1 buffers to 19242572390 bytes Setting queued_chunks_limit_size for each buffer to 2293 Setting chunk_limit_size for each buffer to 8388608 2020-09-29 14:44:52 +0000 [error]: unexpected error error_class=Errno::ENOENT error="No such file or directory @ rb_sysopen - " 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluent-plugin-kafka-0.13.1/lib/fluent/plugin/kafka_plugin_util.rb:41:in `read' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluent-plugin-kafka-0.13.1/lib/fluent/plugin/kafka_plugin_util.rb:41:in `read_ssl_file' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluent-plugin-kafka-0.13.1/lib/fluent/plugin/out_kafka2.rb:109:in `refresh_client' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluent-plugin-kafka-0.13.1/lib/fluent/plugin/out_kafka2.rb:182:in `start' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/root_agent.rb:203:in `block in start' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/root_agent.rb:182:in `block (2 levels) in lifecycle' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/agent.rb:119:in `block (2 levels) in lifecycle' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/agent.rb:118:in `each' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/agent.rb:118:in `block in lifecycle' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/agent.rb:111:in `each' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/agent.rb:111:in `lifecycle' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/root_agent.rb:181:in `block in lifecycle' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/root_agent.rb:178:in `each' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/root_agent.rb:178:in `lifecycle' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/root_agent.rb:202:in `start' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/engine.rb:274:in `start' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/engine.rb:219:in `run' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/supervisor.rb:816:in `run_engine' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/supervisor.rb:559:in `block in run_worker' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/supervisor.rb:741:in `main_process' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/supervisor.rb:554:in `run_worker' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/lib/fluent/command/fluentd.rb:330:in `<top (required)>' 2020-09-29 14:44:52 +0000 [error]: /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:59:in `require' 2020-09-29 14:44:52 +0000 [error]: /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:59:in `require' 2020-09-29 14:44:52 +0000 [error]: /usr/local/share/gems/gems/fluentd-1.7.4/bin/fluentd:8:in `<top (required)>' 2020-09-29 14:44:52 +0000 [error]: /usr/local/bin/fluentd:23:in `load' 2020-09-29 14:44:52 +0000 [error]: /usr/local/bin/fluentd:23:in `<main>' 2020-09-29 14:44:52 +0000 [error]: unexpected error error_class=Errno::ENOENT error="No such file or directory @ rb_sysopen - " 2020-09-29 14:44:52 +0000 [error]: suppressed same stacktrace The fluentd works well if all keys(ca-bundle.crt, tls.crt and tls.key) are provided in the kafka secret.
