Hello, dear community, I am very new to Elasticsearch. I have been asked to deploy the ELK stack on AWS EKS and unfortunately, I am facing some issues. I am deploying the ELK stack in the following order via Helm chart with the following commands. ```auto # helm install elasticsearch elastic/elasticsearch -f k8s/value-elasticsearch.yaml -n monitoring # helm install kibana elastic/kibana -n monitoring # helm install fluentd bitnami/fluentd -n monitoring ``` After some time I see that all pods and services are running successfully. ```auto ^Czhajili$ kubectl get pods --namespace=monitoring NAME READY STATUS RESTARTS AGE elasticsearch-master-0 1/1 Running 0 14m elasticsearch-master-1 1/1 Running 0 14m elasticsearch-master-2 1/1 Running 0 14m fluentd-0 1/1 Running 0 9m22s fluentd-2j6h4 1/1 Running 4 (8m24s ago) 9m22s fluentd-4pt44 1/1 Running 4 (8m19s ago) 9m22s fluentd-8rl4d 1/1 Running 4 (8m24s ago) 9m22s fluentd-drcmx 1/1 Running 4 (8m33s ago) 9m22s kibana-kibana-fc8cbfc5d-xx4fc 1/1 Running 0 10m ``` After applying configmap for fluentd ,I am expecting to see some indices created already ,but I dont see. After checking logs for elasticsearch I see following logs ```auto io.netty.handler.codec.ByteToMessageDecoder.callDecode(ByteToMessageDecoder.java:449)\n\t... 16 more\n"} {"@timestamp":"2022-12-30T18:07:14.300Z", "log.level": "WARN", "message":"http client did not trust this server's certificate, closing connection Netty4HttpChannel{localAddress=/127.0.0.1:9200, remoteAddress=/127.0.0.1:52054}", "ecs.version": "1.2.0","service.name":"ES_ECS","event.dataset":"elasticsearch.server","process.thread.name":"elasticsearch[elasticsearch-master-0][transport_worker][T#1]","log.logger":"org.elasticsearch.xpack.security.transport.netty4.SecurityNetty4HttpServerTransport","elasticsearch.cluster.uuid":"l-bWntZXReSXSVs_tGQZzQ","elasticsearch.node.id":"BgxN566LQGiHFOv7FXk2kw","elasticsearch.node.name":"elasticsearch-master-0","elasticsearch.cluster.name":"elasticsearch"} {"@timestamp":"2022-12-30T18:07:17.750Z", "log.level": "WARN", "message":"http client did not trust this server's certificate, closing connection Netty4HttpChannel{localAddress=/127.0.0.1:9200, remoteAddress=/127.0.0.1:52068}", "ecs.version": "1.2.0","service.name":"ES_ECS","event.dataset":"elasticsearch.server","process.thread.name":"elasticsearch[elasticsearch-master-0][transport_worker][T#1]","log.logger":"org.elasticsearch.xpack.security.transport.netty4.SecurityNetty4HttpServerTransport","elasticsearch.cluster.uuid":"l-bWntZXReSXSVs_tGQZzQ","elasticsearch.node.id":"BgxN566LQGiHFOv7FXk2kw","elasticsearch.node.name":"elasticsearch-master-0","elasticsearch.cluster.name":"elasticsearch"} {"@timestamp":"2022-12-30T18:09:22.014Z", "log.level": "WARN", "message":"caught exception while handling client http traffic, closing connection Netty4HttpChannel{localAddress=/127.0.0.1:9200, remoteAddress=/127.0.0.1:34872}", "ecs.version": "1.2.0","service.name":"ES_ECS","event.dataset":"elasticsearch.server","process.thread.name":"elasticsearch[elasticsearch-master-0][transport_worker][T#1]","log.logger":"org.elasticsearch.http.AbstractHttpServerTransport","elasticsearch.cluster.uuid":"l-bWntZXReSXSVs_tGQZzQ","elasticsearch.node.id":"BgxN566LQGiHFOv7FXk2kw","elasticsearch.node.name":"elasticsearch-master-0","elasticsearch.cluster.name":"elasticsearch","error.type":"io.netty.handler.codec.DecoderException","error.message":"javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca","error.stack_trace":"io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca\n\tat ``` Could you please kindly help me? ---
