Fluentd is an open source data collector, which lets you unify the datacollection and consumption for a better use and understanding of data.

www.fluentd.org

These tags have image version postfix. This updates many places so we need feedback for improve/fix the images.

Current images use fluentd v1 series.

• v1.19.2-2.0,v1.19-2,edge,latest(v1.19/debian/Dockerfile) (Since v1.19.0, alpine image will not be shipped anymore.)
• v1.19.2-debian-2.0,v1.19-debian-2,edge-debian(multiarch image for arm64(AArch64), armhf and amd64(x86_64))
• v1.19.2-debian-amd64-2.0,v1.19-debian-amd64-2,edge-debian-amd64(v1.19/debian/Dockerfile)
• v1.19.2-debian-arm64-2.0,v1.19-debian-arm64-2,edge-debian-arm64(v1.19/arm64/debian/Dockerfile)
• v1.19.2-debian-armhf-2.0,v1.19-debian-armhf-2,edge-debian-armhf(v1.19/armhf/debian/Dockerfile)
• v1.19.2-windows-ltsc2019-1.0,v1.19-windows-ltsc2019-1(v1.19/windows-ltsc2019/Dockerfile)
• v1.19.2-windows-ltsc2022-1.0,v1.19-windows-ltsc2022-1(v1.19/windows-ltsc2022/Dockerfile)

We recommend to use debian version for production because it uses jemalloc to mitigate memory fragmentation issue.

If you want to know the detail of supported image tags, seeTAGRULE explanation.

Checkfluentd-kubernetes-daemonset images.

To create endpoint that collects logs on your host just run:

docker run -d -p 24224:24224 -p 24224:24224/udp -v /data:/fluentd/log fluent/fluentd:v1.3-debian-1

Default configurations are to:

• listen port24224 for Fluentd forward protocol
• store logs with tagdocker.** into/fluentd/log/docker.*.log(and symlinkdocker.log)
• store all other logs into/fluentd/log/data.*.log (and symlinkdata.log)

fluentd arguments can be appended to thedocker run line

For example, to provide a bespoke config and makefluentd verbose, then:

docker run -ti --rm -v /path/to/dir:/fluentd/etc fluent/fluentd -c /fluentd/etc/<conf> -v

The first-v tells Docker to share '/path/to/dir' as a volume and mount it at /fluentd/etcThe-c after the container name (fluentd) tellsfluentd where to find the config fileThe second-v is passed tofluentd to tell it to be verbose

Use-u option withdocker run.

docker run -p 24224:24224 -u foo -v ...

We can't notice comments in the DockerHub so don't use them for reporting issue or asking question.

Due to a change in the default UID invX.Y-A andvX.Y.Z-A.B images since v1.19,you may encount permission errors when writing to mounted volumes.To resolve this, please chown your data directories to the new UID.
