How to connect with elastic cloud?

[xncbf]

I organized ek stack by elastic cloud. But i can't found any field for elastic cloud user and password. I tried this but i can't get any connections.

  output-elasticsearch.conf: |
    [OUTPUT]
        Name            es
        Match           *
        Host            ${FLUENT_ELASTICSEARCH_HOST}
        Port            ${FLUENT_ELASTICSEARCH_PORT}
        HTTP_User       ${FLUENT_ELASTICSEARCH_USER}
        HTTP_Passwd     ${FLUENT_ELASTICSEARCH_PASSWORD}
        Logstash_Format On
        Retry_Limit     False

@xncbf : I have a similar issue. Do you solve yours ? Here is the fluent bit documentation about elasticsearch output plugin, it looks like you have the right parameters.

Here is my log output from a random fluent-bit 1.3.3 daemonset :

[2019/11/29 12:44:51] [error] [io fd=50] error sending data to: elasticsearch-es-http:9200 (Broken pipe)

And my conf :

  output-elasticsearch.conf: |
    [OUTPUT]
        Name            es
        Match           *
        Host            ${FLUENT_ELASTICSEARCH_HOST}
        Port            ${FLUENT_ELASTICSEARCH_PORT}
        Logstash_Format On
        Replace_Dots    On
        Retry_Limit     False
        HTTP_User       ${FLUENT_ELASTICSEARCH_USER}
        HTTP_Passwd     ${FLUENT_ELASTICSEARCH_PASSWORD}

@ledroide , did you find out the solution?

I was having the same problem as you, which I fixed by enabling tls on the output configuration.

  output-elasticsearch.conf: |
    [OUTPUT]
        Name            es
        Match           *
        Host            ${FLUENT_ELASTICSEARCH_HOST}
        Port            ${FLUENT_ELASTICSEARCH_PORT}
        HTTP_User       ${FLUENT_ELASTICSEARCH_USER}
        HTTP_Passwd     ${FLUENT_ELASTICSEARCH_PASSWORD}
        Logstash_Format On
        Replace_Dots    On
        Retry_Limit     False
        tls             On

The errors stopped being logged, by I still couldn't make fluent-bit send anything to my Elasticsearch hosted on Elastic Cloud.

I'm having this output now on fluent-bit containers after adding tls:

UPDATE

Actually the logs are working for me now.

The only thing left for me was to create the Index Pattern in Kibana, so I could visualize the logs. I created a Index Pattern for logstash-*, and can see the logs now. But I don't why exactly they are being created in that index, since the default is fluentbit.

But I also think @ledroide 's problem is not http, as I said before. I tested and it also worked.

Besides using tls On make sure not to include the protocol (https://) part in your FLUENT_ELASTICSEARCH_HOST. At least that was my issue.

Change the following to solve the problem

fluent-bit-configmap.yaml

output-elasticsearch.conf: | [OUTPUT] Name es Match * Host ${FLUENT_ELASTICSEARCH_HOST} Port ${FLUENT_ELASTICSEARCH_PORT} HTTP_User ${FLUENT_ELASTICSEARCH_USER} HTTP_Passwd ${FLUENT_ELASTICSEARCH_PASSWORD} Logstash_Format On Logstash_Prefix k8s-fluentbit Replace_Dots On Retry_Limit False tls On tls.verify Off Type flb

fluent-bit-ds.yaml env: - name: FLUENT_ELASTICSEARCH_HOST value: "elastic-es-http.logging.svc" - name: FLUENT_ELASTICSEARCH_PORT value: "9200" - name: FLUENT_ELASTICSEARCH_SCHEME value: "https" - name: FLUENT_ELASTICSEARCH_USER value: "elastic" - name: FLUENT_ELASTICSEARCH_PASSWORD value: "*****"
