Explore Linux cgroups, systemd and cgroupfs drivers, and how they allocate CPU and memory to containers, and learn to configure or change the cgroup manager in Kubernetes.
Explore container networking concepts in Kubernetes, including unique container IPs across VMs, CIDR ranges, pod networking, and node communication using loopback and IP addresses.
Explore liveness, readiness, and startup probes, including http health checks with a healthz endpoint, for maintaining pod health and orchestrating restarts using various probe types.
Explore workloads and services by examining service object, service types, and service endpoints. Compare EndpointSlice, ExternalName service, and headless service to understand their roles.
Learn how a Kubernetes service with a selector automatically creates and updates an endpoint that maps pod IPs, enabling traffic redirection; explore services without selectors for external or cross-namespace use.
Connect to a redis server at 192.0.2.42:9376 from a cluster by creating a service with no selectors and a matching endpoint, then access via redis-svc.
Learn how a daemonset ensures one pod per node to collect logs or metrics, with fluentd as a typical example, and see how it differs from deployments.
Create a user1 x509 certificate, generate and sign a csr using Kubernetes csr, and configure kubectl contexts for user authentication and authorization.
Explore node affinity with soft rule expressions and weighted scoring, using weights 50, 30, 40 and labels server=data, node type high CPU, disktype pd to guide pod placement.
Explore taint and tolerance in Kubernetes, learning how taints prevent pod scheduling and how tolerations permit it, including no schedule, prefer no schedule, and no execute.
