Hello,
I generated with certutils my own ca.crt, ca.key and the certificates for each node(with an instances.yml), however when I load the elastic and kibana, kibana docker container logs says:
kibana_1 | [2024-09-17T12:15:58.476+00:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. unable to verify the first certificate
In order to check if the ca.crt and credentials are correct from inside the Kibana container, I do in a shell(inside kibana container):
curl --cacert /usr/share/kibana/config/certs/ca/ca.crt -v https://es01:9200 -u kibana_system:xxxxx
and the elastic node response is correct, so I'm not sure why Kibana is not able to connect to elasticsearch. But I can say that the certificate authority is good. Just to note that I used
/usr/share/elasticsearch/bin/elasticsearch-reset-password -u kibana_system inside the elastic container in order to set the kibana password for that user and after that I modified the docker-compose.yml and finally restart the kibana container.
Can someone help me? thanks!
