This container is designed to run as a DaemonSet and forwards pod logs to a syslog listener for all pods running on a node. Log forwarding is implemented with RSYSLOG and uses omfwd module.
Configuration can be done with environment variables:
- RSYSLOG_TARGET - Remote syslog listener
- RSYSLOG_PORT - Remote syslog listener port
- RSYSLOG_PROTOCOL - Remote syslog listener protocol (udp/tcp)
A working example of a deployment daemonset can be found in the k8s directory, along with an example ConfigMap. You will need to adjust the configmap to suit your system.
The Makefile included here is set up to assist development and testing of the system,
using k3d. It will fully set up a test cluster, install all necessary
components, and run a simple test.
Use make test to perform all of these
NOTE: there is currently an occasional timing issue where the test will fail right after the
cluster is up. If this happens, wait 30 seconds and attempt make test again.
