I have generated elastic-stack-ca.p12
Then I use this command to generate crt and key files for logstash.
./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12 --name logstash --dns [?] --ip [elk server's ip] --pem --out logstash.zip
I don't set any dns for my elk server, what does the param
--dns should be? I was told this param is mandatory.
