fluentd-pilot

fluentd-pilot is an awesome docker log tool. With fluentd-pilot you can collect logs from docker hosts and send them to your centralize log system such as elastichsearch, graylog2, awsog and etc. fluentd-pilot can collect not only docker stdout but also log file that inside docker containers.

Try it

Prerequisites:

docker-compose >= 1.6
Docker Engine >= 1.10

git clone git@github.com:AliyunContainerService/fluentd-pilot.git
cd fluentd-pilot/quickstart
./run

Then access kibana under the tips. You will find that tomcat's has been collected and sended to kibana.

Create index:

Query the logs:

Quickstart

Run pilot

docker run --rm -it \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /:/host \
    registry.cn-hangzhou.aliyuncs.com/acs-sample/fluentd-pilot:latest

Run applications whose logs need to be collected

Open a new terminal, run the application. With tomcat for example:

docker run -it --rm  -p 10080:8080 \
    -v /usr/local/tomcat/logs \
    --label aliyun.logs.catalina=stdout \
    --label aliyun.logs.access=/usr/local/tomcat/logs/localhost_access_log.*.txt \
    tomcat

Now watch the output of fluentd-pilot. You will find that fluentd-pilot get all tomcat's startup logs. If you access tomcat with your broswer, access logs in /usr/local/tomcat/logs/localhost_access_log.\*.txt will also be displayed in fluentd-pilot's output.
