use tls and elastic in fluentbit

Question

I'm trying to send logs to my elastic pod with FluentBit service on a different VM. I configured ingress for elastic.

I configured the FluentBit that way:

[OUTPUT]
    Name  es
    Match *
    Host <host_ip>
    Port 443
    #Retry_Limit 1
    URI /elastic
    tls On
    tls.verify Off

but I keep getting the following error :

[2020/10/25 07:34:09] [debug] [out_es] HTTP Status=413 URI=/_bulk

it is possible to yo use TLS in elastic output? if yes can you suggest what I configured wrong?

HTTP 413 is a code for Payload Too Large. Try increasing the http.max_content_length in elasticsearch.yml

Also note that you are using tls.verify Off which does not make sense longterm. If you have an ingress with a certificate (LetsEncrypt?) it should be OK to set tls.verify On. Otherwise all looks correct.

use tls and elastic in fluentbit
