Docker fluentdのlogging driverを使ってみる
前提
docker起動している
fluentdの起動
# docker run --name fluentd --rm -d -p 24224:24224 fluent/fluentd
(省略)
nginxの起動、ログをfluentdに吐く
# docker run --name nginx --rm -d -p 10080:80 --log-driver=fluentd --log-opt=fluentd-async-connect --log-opt=fluentd-address=localhost24224 --log-opt=tag=docker.{{.ID}} nginx
(省略)
-log-opt=fluentd-async-connect を付けないとエラーだめ？
fluentd、nginxの状況確認
# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
131cc6cbf72f nginx "nginx -g 'daemon of…" 25 minutes ago Up 25 minutes 0.0.0.0:10080->80/tcp nginx

nginxにアクセスしてログを吐かせる
# curl localhost:10080
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!
(省略)
</title></html>
ログが出ていることを確認
# docker exec -it fluentd cat /fluentd/log/docker.log

課題
ログの時刻がJSTじゃない。
