WARNING: no logs are available with the 'fluentd' log driver

[Sandeep 768]

Hi Team,

I have created one container running java application producing logs to Console.

Created one Fluentd container which is configured to listen to above log driver.

I am getting 

WARNING: no logs are available with the 'fluentd' log driver

Please find below files for reference

In docker-compose.yml

version: '3'

###  Follow the deployment instructions in the Getting Started Readme. ###

services:

  demoapp:

    build: .

    restart: unless-stopped

    logging:

      driver: "fluentd"

      options:

        fluentd-address: localhost:24224

        fluentd-async-connect: "true"

        tag: demoservice

    links:

      - fluentd

    networks:

      - demo   

      

  fluentd:

    build: ./demo-fluentd

    restart: unless-stopped

#    volumes:

#      - webauth-logs:/opt/osp/tomcat/logs

    networks:

      - demo      

    ports:

      - "24224:24224"

      - "24224:24224/udp"

networks:

  demo:

    driver: bridge

fluent.cnf

<match demoservice>

  @type stdout

</match>

If required, I can share my java program as well which logs some messages to Console output in every 5 seconds

I'm having exactly the same problem.

[Mr. Fiber]

`localhost` can refer other containers? docker-compose support it?

Generally, `localhost` refers to container itself.

In addition, you need to add forward input plugin configuration to your fluentd configuration.

For what it's worth, yesterday I realised that my setup was actually working, but the error is still happening.

I think the warning is more related to the output to the console than to the actual logging by fluentd.

Hi @repeatedly, thank for your reply.

Now I am able to collect logs both from Console Logger and File Logger.

There was some wrong configuration.

For log driver in Docker compose, if I use below source, it works fine.

<source>

  @type  forward

  port  24224

  bind 0.0.0.0  

</source>
