@type forwardで受け取って@type stdoutで標準出力にそのまま表示する
まずfluentedの設定ファイルを準備
ターミナルA
% cat test.conf (git)-[develop]
<source>
@type forward
</source>
<match *>
@type stdout
</match>
受け用のFluentedのDockerコンテナを立ち上げる
ターミナルA
% docker run -it -p 24224:24224 -v [test.confへの絶対パス]:/fluentd/etc/test.conf -e FLUENTD_CONF=test.conf fluent/fluentd:latest
送る用のコンテナを立ち上げる
ターミナルB
% docker run --log-driver=fluentd [IMAGE ID]
そうするとターミナルAの方でログが逐次出力される
ターミナルA
% docker run -it -p 24224:24224 -v /home/kure/repo/kanrinmaru-worker/kure-docker-ubuntu/test.conf:/fluentd/etc/test.conf -e FLUENTD_CONF=test.conf fluent/fluentd:latest
