"Fluent Bit is an open source and multi-platform Log Forwarder which allows you to collect data/logs from different sources, unify and send them to multiple destinations."
The container-fluent-bit repo contains a Dockerfile (and Jenkinsfile) to build (and test) the quay.io/samsung_cnct/fluent-bit container.
This container is used by the chart-fluent-bit repo, among others. See the chart repo for information on installing and configuring Fluent Bit on Kubernetes. The fluent-bit.conf included with the container artifact is intended for debugging only.
Deployments to Kubernetes should use a ConfigMap. For an example, from the chart repo, see fluent-bit.yaml.
