is there a way to get for each MariaDB deployed instance the relative SSL certificate+key couple?
Looking at the MariaDB SSL documentation there's no mention of keys or certificates, but just the CA, which is specifically this https://www.digicert.com/CACerts/BaltimoreCyberTrustRoot.crt.pem.
Point is that to make MaxScale enforce using SSL, you need to pass the CA, the certificate and the key.
Otherwise, if you specify just the CA, you get this:
2021-01-18 17:26:05 error : (2) SSL operation failed, Backend DCB in state DCB::State::POLLING fd 86 return code -1. More details may follow. 2021-01-18 17:26:05 error : (2) error:1408F10B:SSL routines:ssl3_get_record:wrong version number
And all the connections fail.
Can you help me find out a workaround on this?
