Kingsly - The Cert Manager


Tasdik Rahman


Problem Statement

Manage SSL/TLS certificate lifecycle for various backends which would include but not limited to
- IPSec VPNs
- HAProxy/envoy proxy

Existing Solutions

Generate certs using openssl(error prone) or use managed solution(expensive)


  • We built kingsly, which would act as broker between clients and letsencrypt, serving the clients with SSL certs.
  • It takes care of renewal of certs before their expiry dates.
  • extensible by writing custom clients to automate the whole manual process of updating certs with an example client.


Will go over the problem statement of how managing certs was a difficult problem for us and then how we went ahead solving it using kingsly.
