What's Inside

Module 1: introduction

  • Architecture overview: master node, worker nodes, etcd, kubelet, controllers
  • Anatomy of a pod: the main container, init containers, sidecars, labels, probes
  • Basic commands and debugging tricks
  • Practice: deploy an application as a Pod with the primary process, umplement initialization logic executed in init containers, add watchdog containers and probes

Module 2: deployments and services

  • Anatomy of a deployment: types of deployments, replica set, replica count
  • Introduction to Kubernetes networking
  • Anatomy of a service: traffic routing, labels, port mapping
  • Service types: node port, cluster IP, load balancer
  • Anatomy of kubeproxy
  • Introduction to service meshes
  • Practice: configure application traffic routing, implement different service types, implement canary release procedure

Module 3: storage

  • Persistent volumes: volumes types, volume resizing, volume snapshots
  • Working with complex deployments: stateful sets
  • Job and Cron-jobs
  • Practice: configure stateful deployment for an HA database (PostgreSQL or MariaDB); configure an HA caching layer (Redis) for your application; implement a scheduled backup procedure for an HA database

Module 4: configuration management

  • Configuration management: config maps, reloadable configurations
  • Deployment time configuration injection with Kustomize
  • Secrets management and integration with service discovery service (Consul and Vault)
  • Introduction into Kubernetes admission webhooks and cluster events
  • Practice: implement two environments (applications + data storage) running in different namespaces with different settings, implement automatic configuration propagation at run time using different mechanisms

Module 5: resource control and scheduling

  • Resource management: resource requests and limits
  • Anatomy of a node pool
  • Taints and tolerations, scheduling internals
  • Dive into built-in resource monitoring and metrics
  • Auto-scaling policies and range limiters
  • Practice: adjust resource limits for existing deployments; implement auto-limit and auto-scaling policies

Module 6: security

  • Cluster security with RBAC, service accounts, cluster roles, namespace security
  • Integrating with external security providers
  • Pod security and network policies
  • Practice: implement cross-environment security policies with the help of service accounts and external LDAP integration; limit network traffic between pods

Module 7: advanced operations

  • Day-1 vs. Day-2 operations
  • Introduction to Helm charts
  • Introduction to Operator pattern
  • Custom resource definitions
  • Practice: implement operator from a given template with Bash or Python
