Hello Team,

I am new to Kubernetes and splunk, I have a requirement to push logs that are generated from my spring boot app running under k8s pods to splunk,

How can I forward the logs that are generating under pod ?

I can access the logs by using the command 

kubectl logs <pod-name>

@dmuley - You need to install Splunk Universal forwarder onto the Kubernetes instance and monitor log files under the `/var/log` directory usually.

But you can check the location of log files with the below command: (the command is deprecated BTW)

kubectl --log-dir

 

How to install UF - https://docs.splunk.com/Documentation/Forwarder/9.0.4/Forwarder/Installanixuniversalforwarder

How to monitor log files - https://docs.splunk.com/Documentation/Splunk/9.0.4/Data/Monitorfilesanddirectorieswithinputs.conf 

 

I hope this helps!!!

Hi @dmuley 

If using EKS from AWS then you can use Splunk Connect for Kubernetes

You can also send logs from the Master node by installing Splunk Universal Forwarder and configuring /var/log or any other log path as per your need.

For application specific events, you can use Splunk HTTP Event Collector (HEC) to send custom events to Splunk.

 Be sure to check the correct Splunk version documentation for configuration and implementation.
