   to

   $ModLoad imudp
   $UDPServerRun 514
   

2. Challenge

   Configure Docker to use syslog.

   Create the daemon.json file.

   mkdir /etc/docker
   vim /etc/docker/daemon.json

     "log-opts": {
       "syslog-address": "udp://PRIVATE_IP:514"
     }

3. Challenge

   Create a container using syslog.

   sudo systemctl enable docker
   sudo systemctl start docker
   

   Create a container called syslog-logging using the httpd image.

   docker container run -d --name syslog-logging --log-driver none httpd

   Create a container using a JSON file.

   Create a container that uses the JSON file for logging.

   docker container run -d --name json-logging --log-driver json-file httpd
   

5. Challenge

   Verify that the `syslog-logging` container is sending its logs to syslog.

   Make sure that the syslog-logging container is logging to syslog by checking the message log file:

   tail /var/log/messages
   

6. Challenge

   Verify that the `json-logging` container is sending its logs to the JSON file.
