Openshift Logging Bug Fix Release (5.0.2)Openshift Logging Bug Fix Release (5.0.2) You use the Red Hat OpenShift Logging product to forward, store, and visualize log data from your cluster. Changes to the Red Hat OpenShift Logging product: * If you did not set `.proxy` in the cluster installation configuration, and then configured a global proxy on the installed cluster, a bug prevented Fluentd from forwarding logs to Elasticsearch. To work around this issue, in the proxy/cluster configuration, set `no_proxy` to `.svc.cluster.local` so it skips internal traffic. The current release fixes the proxy configuration issue. Now, if you configure the global proxy after installing an OpenShift cluster, Fluentd forwards logs to Elasticsearch. (*LOG-1187*, *BZ#1915448*) * Previously, forwarding logs to Kafka using chained certificates failed with error "state=error: certificate verify failed (unable to get local issuer certificate)." Logs could not be forwarded to a Kafka broker with a certifica...
