Free SSL for Kubernetes with Cert-Manager
Source: YouTube · That DevOps Guy · published Dec 30, 2020 · 19:16
Cert-manager automates SSL certificate management in Kubernetes, eliminating manual certificate replacement and reducing security risks 0:40, 2:15.
Key Takeaways:
• SSL certificates in Kubernetes are stored as secrets and expire after 1-2 years, causing potential disruptions if not manually replaced 0:20
• Manual certificate management introduces operational overhead and security risks through human error and potential certificate leakage 0:56
• Cert-manager integrates with certificate authorities like Let's Encrypt to automatically generate and renew certificates 1:27, 2:15
• Implementation requires installing cert-manager, configuring issuers (self-signed or Let's Encrypt), and creating certificate resources 5:05, 9:44
• Cert-manager watches certificate secrets and automatically renews them before expiration, providing continuous security 18:26
Cert-manager transforms SSL certificate management from a manual, error-prone process to an automated, secure system within Kubernetes clusters.

so how many ssl certificates do you have in your kubernetes cluster and on top of that how many kubernetes clusters do you manage then you probably already know that you have to manually replace all these certificates every time they expire in kubernetes ssl or tla certificates are stored as kubernetes secrets they are generally loaded into namespaces to be consumed by applications or ingress controllers one or two years later they expire and may expire at different intervals causing disruptions if they are missed there are two things that come to mind here number one is human error the more kubernetes clusters and namespaces you own the more secrets you have to manage and maintain there is also room for error when replacing these secrets and you are always bound to miss one or two and hav…
