Hello,

im trying to set up TLS in elastic cluster, the cluster works normally without tls, communicating in http, im received from company some certificates for all node of my cluster, ca\_cert.crt, subca\_cert.crt, machinename.crt and key, at this point i have installed them on each machine, but i have a doubt:

- have I execute step to generate node certificates :elasticsearch-certutil ca and elasticsearch-certutil cert --ca ?

I think no but im not sure  
Thanks
