Hi Team,
I configured elasticsearch cluster using official helm chart and enabled x-pack security feature by creating PKC#12 certificates. Elasticsearch pod status shows running state when I check in kubernetes cluster. However, when i check the log message of elasticsearch pod, I found below given stackstrace. Coudl you anyone help me out what is missing in ealsticsearch yaml file.
Here is the output of elasticsearch.yaml file.
sh-4.2$ cat elasticsearch.yml
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: /usr/share/elasticsearch/config/certs/elasticsearch-master.p12
xpack.security.transport.ssl.truststore.path: /usr/share/elasticsearch/config/certs/elasticsearch-master.p12
xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.truststore.path: /usr/share/elasticsearch/config/certs/elasticsearch-master.p12
xpack.security.http.ssl.keystore.path: /usr/share/elasticsearch/config/certs/elasticsearch-master.p12
sh-4.2$
