This course covers the core concepts typically used to build and administer a Kubernetes cluster in production, using vendor-independent tools. We build a cluster, determine network configuration, grow the cluster, deploy applications and configure the storage, security and other objects necessary for typical use. This course offers exposure to the many skills necessary to administer Kubernetes in a production environment.

At the Open Source Leadership Summit (OSLS), the Cloud Native Computing Foundation (CNCF), which sustains and integrates open-source, cloud native technologies such as Prometheus and containerd, and Chen Goldberg, Google Cloud’s director of engineering, announced that Kubernetes is the first project to graduate from the CNCF.
Cilium is open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms like Docker and Kubernetes. Cilium 1.0.0-rc4 has recently been released, which includes: the Cloud Native Computing Foundation (CNCF)-hosted Envoy configured as the default HTTP/gRPC proxy; the addition of a
When deploying applications in a Kubernetes cluster, certain types of services are commonly required. Many applications require a database, a storage service, a message broker, identity management, and so on. You have enough work on your hands containerizing your own application. Wouldn’t it be handy if those other services were ready and available for use inside the cluster?
A transaction trace is a GPS system for web performance: it paints a rich picture of the flow of a web request through your code.
So, why doesn’t everybody trace? I believe there are two reasons:
