Practical Kubernetes Guide

Explore kubenet as the default network mode in azure kubernetes service, where nodes borrow subnet ips while pods receive a pod cidr, with nat routing and limited route table entries.

Explore how Azure CNI overlay mode solves IP exhaustion by assigning each node a unique pod CIDR, isolating pod IPs from the subnet and avoiding extra route hops.

Compare Kubernetes with Azure CNI overlay, highlighting up to 1000 nodes per cluster, no per-node route-table limits, and simplified pod networking.

Install and configure Prometheus and Grafana operators in Kubernetes using the operator lifecycle manager and Kube Prometheus. Explore CRDs, dashboards, and pre-configured monitoring components.

Explore deploying a Kubernetes logging stack using fluentd, fluent bit, Elasticsearch, and Kibana with operators. Learn to install the logging and Elasticsearch operators and access Kibana for logs.

Create a pod reader role and a role binding in a namespace, assign them to users and groups, and verify access with kubectl can-i for authorized and unauthorized users.

Explore passwordless identities in a Kubernetes workflow by linking a service account to an Azure managed identity, granting access to Key Vault secrets via workload identity.
