Hello, I’m using LetsEncrypt on two servers working behind a load balancer and wanted to ask if the setup I’m using would be stable going forward.
The Load Balancer is set up in SSL pass-through mode. Initially, I had only server 1, whose IP I mapped to the domain and obtained an SSL. Then I created the second server and am syncing the certificate files between them by using
/etc/letsencrypt. Finally, I activated the load balancer and switched the DNS records for the domain to point to the load balancer.
It all seems to be working as expected, but I have a nagging suspicion that I might be overlooking something. The biggest question for me is, when it the first server renews its certificate after 30 days, will the second server automatically start using the same certificate? It seems so, and to test that, I issued a new certificate on server 1, after which the files got synced to the second server and the overall setup seems to be working smoothly.
All in all, can I count on this setup going forward, or is there something I should be worried about?
