Syslog data from external device into ELK Stack

[pooch]

I have ELK collecting logs from all of my pods within my Kubernetes cluster. I would also like to collect logs from an external PA firewall (syslog) and have them processed into Elasticsearch. I am a bit confused on how to proceed.

1. Do I expose Filebeat to to the external world using an ingress?
2. Can I even ship syslog data using HTTP?
3. Am I going about this all wrong?

Much thanks for your input.

1. If you want to send to it as a syslog listening endpoint, it needs to be suitably exposed
2. rsyslog would speak http directly to Elasticsearch with it's integration
3. Nope!

Thank you for your input Mark!

Hmmm I tried to create a service and an ingress for Filebeat to to intake syslog data but it seems like this is not yet supported.

Sorry, I'm not much use on kubernetes!
