bind-address 127.0.0.1 문제. 나는 mySQL을 도커에서 돌리고 있는데, 관련이 있을까? 내부적으로 같은 망이니 127이 맞을거 같긴 한데.

어쨌든 ELK사용하던 중에 일어난 일이니까, 엘라스틱에 물어본다.
Are you sure that the jdbc_connection_string is correct? A communication link failure exception usually happens when jdbc is not able to connect at all.
This could be because of a TLS error, or your bind-address for your mysql server is not 0.0.0.0, your port is incorrect or not listening, your sql server is not running, a firewall is preventing external connections, and much more. You need to check all the basics first.
