Hi! My name is ChengHao, and I specialize in Kubernetes / DevOps / SRE. I occasionally share beginner 101 tutorials in various communities and enjoy documenting my learning journey. I’m currently a Cloud Native Computing Foundation (CNCF) Ambassador, a Kubestronaut, a Co-organizer of the Cloud Native Taiwan User Group (CNTUG), and a Maintainer of the open-source project Kubespray. Feel free to reach out if you have any questions about CNCF or Kubernetes—I’d love to chat!
