Automate Machine Identities in Kubernetes

cert-manager handles the issuing and management of x.509 machine identities within Kubernetes clusters. cert-manager automates issuing certificates on demand using Kubernetes APIs, as well as renewing the certificates before they expire. cert-manager comes with support for commonly-used certificate issuers, and can be extended to support others as needed. cert-manager allows you to restrict who can use each issuer, allowing you to apply policy within your organization.

Integrations with popular Kubernetes extensions

The certificates can be consumed in any way you want, and cert-manager comes with support for use with Kubernetes Ingress. Many other Kubernetes services integrate with cert-manager through its APIs, including service mesh, allowing them to seamlessly issue certificates that are compliant with your policies.
