Some Genesys service containers write logs to log files. This method is similar to that of the structured logging in terms of the the log aggregation. Here, a sidecar to be applied to a sidecar container that is applied to the service. The sidecar container processes this data and sends it to stdout/stderr. Any log aggregator (such as Fluentd) picks up this data and applies the same operations as that of standard structured logs.

Services that can log on to stdout/stderr can be ingested into Elasticsearch by using sidecar container for processing the logs. The service writes the logs to EmptyDir and sidecar container collects and processes the output to the /var/log/pods directory.

A log aggregator will scrape directory and post log data to the Elasticsearch index.

What does a sidecar container with a logging agent (like Fluent Bit) require?

You require a ConfigMap that contains the configuration to configure Fluent Bit. For more information on configuring Fluent Bit, refer to Fluent Bit Documentation.

Here is a ConfigMap sample with Fluent Bit version 1.8.x:

## FluenbtBit Configmap
apiVersion: v1
kind: ConfigMap
metadata:
  name: fluent-bit-config
  labels:
    k8s-app: fluent-bit
data:
  fluent-bit.conf: |
    [SERVICE]
        Flush         1
        Log_Level     debug
        Daemon        off
        Parsers_File  parsers.conf
        HTTP_Server   On
        HTTP_Listen   0.0.0.0
        HTTP_Port     2020
 
    @INCLUDE input-kubernetes.conf
    @INCLUDE output-stdout.conf
  input-kubernetes.conf: |
    [INPUT]
        Name              tail
        Tag               kube.*
        Path              <path to logs>
        Parser            docker
        DB                /var/log/flb_kube.db
        Mem_Buf_Limit     5MB
        Skip_Long_Lines   On
        Refresh_Interval  10

  output-stdout.conf: |
    [OUTPUT]
        Name            stdout
        Match           *

You also require a pod that has a sidecar container running Fluentd. The pod mounts a volume where Fluentd can pick up its configuration data. Here is an example:

volumeMounts:
   - name: <log-config-volume>
     mountPath: <mount-path>
 ...
 volumes:
   - name:  <log-config-volume>
   configMap:
     name: <configmap-name>
...
 image: 'fluent/fluent-bit:<version>'
