Hi.

I've inherited an ELK setup as follows:

- Elasticsearch / Logstash / Kibana / Filebeat: version 6.3.0
- Curator: version 5.5.4
- Docker Composer: version 3
- HAProxy: version 1.8.12

I'm planning to upgrade the whole stack as follows:

- Elasticsearch / Logstash / Kibana / Filebeat: version 7.16.2
- Curator: version 5.8.4
- Docker Composer: version 3.8

My question here is about the HAProxy: would the old version compatible with the new ELK stack? If not what version should I go for? I'm struggling to find info about this component.

Thanks

HAProxy is a third party tool and there is no relation with the Elastic Stack.

Some people use it as a Loadbalancer in front of Logstash, Elasticsearch or Kibana, but the version of the HAProxy doesn't matter for the Elastic Stack.

Since you want to upgrade HAProxy, you should go to the last LTS version, which is 2.4

That's exactly as it is used, as a load balancer.

I'll go for the version you've suggested, thanks
