Reroute Quay Enterprise logging for FluentD

Quay Enterprise logging is normally done to /var/log/syslog which is the default logging location for the syslog daemon. Unfortunately, FluentD reads only information that is directed to the standard output (/dev/stdout). To enable FluentD to read Quay logs, the output from syslog needs to be rerouted to /dev/stdout; this can be done in the following manner:

1. Create a new file called syslog-ng-extra.conf with the following content:

   source s_docker_syslog { file("/var/log/syslog"); };
   destination d_docker_syslog { file("/dev/stdout"); };
   log { 
       source(s_docker_syslog); 
       destination(d_docker_syslog); 
   
   };

2. Before we can add the file to QE deployment in Kubernetes, we need to base64 encode the file:

   $ cat /config/syslog-ng-extra.conf | base64 -w 0
   

   The output should look something like this:

   ZXN0aW5hdGlvbiBkX2RvY2tlcl9zeXNsb2cgeyBmaWxlKCIvZGV2L3N0ZG91dCIpOyB9Owpsb

3. Edit the Kubernetes secret file and add the output that you got with base64 to it:
   

   $ kubectl --namespace quay-enterprise edit secret/quay-enterprise-config-secret

   syslog-ng-extra.conf: 

   rc291cmNlIHNfZG9ja2VyX3N5c2xvZyB7IGZpbGUoIi92YXIvbG9nL3N5c2xvZyIpOyB9OwpkZX

4. Recycle all QE pods and let the scheduler start new ones.
