Manage SSL certificates more securely with Certificate Manager
In April 2025, Certificate Manager, KakaoCloud's integrated SSL certificate management service, was officially released. Now you can register and connect certificates from one integrated console, without having to configure certificates separately in each service such as Load Balancer or Kubernetes Engine.
🔐 What is Certificate Manager?
Certificate Manager is a service in the Management group that supports registering SSL certificates and connecting them to various KakaoCloud services. Previously, certificates had to be configured separately for each service. Now certificates can be registered in one place and selected for connection when needed, improving management efficiency and security consistency.
Key features
KakaoCloud Certificate Manager provides features for integrated certificate lifecycle management.
-
🔐 Register and delete certificates You can register SSL certificates directly in the console. By entering the PEM-format certificate body, private key, and chain information including root and intermediate certificates, you can easily add certificates, and register or delete them through an intuitive UI.
-
🧩 Connect to various services A certificate registered once can be applied to various services. Currently, when configuring an HTTPS listener for Load Balancing ALB or a TLS listener for NLB, certificates can be selected from a dropdown. In Kubernetes Engine, registered certificates can also be connected as-is when configuring ALB-based HTTPS ingress. Because the same certificate does not need to be registered repeatedly, configuration is simplified and security consistency and operational efficiency are improved.
-
⏰ Lifecycle and expiration management You can check certificate expiration dates in the console, allowing you to identify and respond to renewal or replacement timing in advance. Certificates can be managed periodically without service interruption, enabling stable operations.
✔️ The improvements from the Certificate Manager release can be summarized as follows.
| Item | Before | After Certificate Manager release |
|---|---|---|
| Certificate registration location | Registered separately by service | Registered centrally in the console and selectable from various services |
| Listener configuration method | Entered directly by service | Select registered certificates from a dropdown |
| Expiration date management | Separate tracking required | Metadata such as expiration date can be checked in the console |
Certificate Manager is provided as a default management service. For detailed usage instructions, see the Certificate Manager user guide.
