→OpenShift router + rsyslog
= OpenShift router + rsyslog =
Starting with OpenShift 3.11, it is possible to define fire up a router that will openShfit automatically launch contain a side car rsyslog container in the router pod and configure HAproxy to send logs to the rsyslog server via an emptyDir volume , which writes them to stdout by default. The configuration of rsyslog is in a configMap.

You can create a router with syslogserver using the '''--extended-logging''' switch with in the command '''' 'oc adm router'''command.
<pre>
# oc adm router myrouter --extended-logging -n default
<br>
Turn on the debug level loging in HAproxy:
<pre>
# oc set env dc / myrouter ROUTER_LOG_LEVEL = debug -n default
You can see that the '''/ var / lib / rsyslog /''' folder is mounted in both containers. You will create the The rsyslog.sock file will be created here in your HAproxy configuration file.

=== router container ===
When we enter the router container, we can see that the configuration has already been lickedmodified:
<pre>
# kubectl exec -it myrouter-2-bps5v / bin / bash -n default -c router
<br>
If you want to reconfigure rsyslog to send logs to eg e.g, logstash then you only need to rewrite the configMap. By default, it rsyslog only writes to stdout what you get.
<pre>
# kubectl get cm rsyslog-config -n default -o yaml
