Logo created for Jetstack's Cert Manager: an open-source, general-purpose certificate management controller for Kubernetes.

NAUTICAL CERT MANAGER LOGO 

The logo was designed to look like a rubber stamp/wax seal, with certificates being given the Cert Manager "seal of approval". I chose to use the image of an anchor and waves (a nod to the consistently nautical theme of Kubernetes products) alongside the brand's iconic blue.
