Fixed In Version: openshift3/ose-logging-fluentd:v3.11.23-1
Doc Type: Bug Fix
Doc Text:
Cause: When using docker with the journald log driver, all container logs, including system and plain docker container logs, are logged to the journal, and read by fluentd. Consequence: fluentd does not know how to handle these non-kubernetes container logs and throws exceptions. Fix: Treat non-kubernetes container logs as logs from other system services e.g. send them to the .operations.* index. Result: Logs from non-kubernetes containers are indexed correctly and do not cause any errors.

Description of problem:
Fluentd does not handle logs from "s2i" containers.
Fluentd expects all container logs from the journal have a CONTAINER_NAME value with a "k8s_" prefix - it doesn't know how to handle the "s2i_" prefix.

Version-Release number of selected component (if applicable): OCP 3.9.27

How reproducible:
Create S2I pod and look for logs in Kibana

Steps to Reproduce:
1. Create a project/namespace. 
2. Create a couple S2I pods in project along with other pods, can use console and pick from catalog. 
3. Later, go to Kibana with the user owner of the project or an user with cluster admin role.

Actual results: 
Logs will be visible for some pods, but not S2I pods.

Expected results:
Logs should be visible for all pods.
