Course Content

Kubernetes Core Concepts for Developers

Understand Kubernetes architecture, including pods, nodes, clusters, and the control plane, from an application development perspective.
Explore key Kubernetes resources, such as deployments, services, and namespaces, for managing applications.
Use kubectl commands to interact with clusters, create resources, and inspect application states.
Learn the declarative approach to application management using YAML manifests for reproducibility.

Pod Design and Configuration

Define pod specifications, including containers, init containers, and environment variables, for application requirements.
Configure multi-container pods with shared volumes and communication strategies for complex applications.
Implement pod lifecycle management, including restart policies and termination behaviors.
Troubleshoot pod misconfigurations, such as invalid container images or environment variable errors.

Application Deployment and Scaling

Create and manage deployments to ensure application availability and rolling updates for zero-downtime releases.
Configure replica sets to maintain desired pod counts and handle scaling requirements.
Implement horizontal pod autoscaling (HPA) based on CPU or custom metrics for dynamic scaling.
Roll back failed deployments and troubleshoot issues like image pull failures or update conflicts.

Service Discovery and Networking

Configure Kubernetes services (ClusterIP, NodePort) to enable application communication within clusters.
Use DNS for service discovery to allow pods to communicate reliably across namespaces.
Implement ConfigMaps and Secrets to inject configuration data and sensitive information into applications.
Troubleshoot networking issues, such as service connectivity or DNS resolution failures, using kubectl.

Storage for Applications

Configure volumes (e.g., emptyDir, hostPath) to provide temporary or local storage for applications.
Use PersistentVolumeClaims (PVCs) to attach persistent storage for stateful applications.
Understand storage classes and their role in dynamic provisioning for cloud-native environments.
Troubleshoot storage-related issues, such as failed mounts or insufficient storage capacity.

Application Observability

Implement liveness, readiness, and startup probes to monitor application health and ensure reliability.
Configure logging to collect container logs and integrate with tools like Fluentd or Elasticsearch.
Use kubectl to access pod logs and debug application runtime issues in real-time.
Set up basic monitoring with metrics (e.g., pod CPU/memory) to track application performance.

Configuration and Secrets Management

Manage application configuration using ConfigMaps to decouple settings from container images.
Secure sensitive data with Secrets for credentials, API keys, or certificates in Kubernetes.
Inject configuration and secrets into pods via environment variables, volumes, or command-line arguments.
Troubleshoot configuration errors, such as missing ConfigMaps or improperly referenced Secrets.

Application Security and Resource Limits

Configure security contexts to restrict pod and container privileges, ensuring least privilege principles.
Set resource requests and limits for CPU and memory to optimize application performance and cluster stability.
Use namespace quotas to enforce resource boundaries for multi-tenant environments.
Mitigate security risks, such as running privileged containers, and troubleshoot resource contention issues.

CI/CD Integration with Kubernetes

Understand CI/CD pipelines and their integration with Kubernetes for automated application deployments.
Use tools like Helm to package and manage application manifests for streamlined deployments.
Implement rolling updates and canary deployments to minimize risks during application releases.
Practice integrating Kubernetes with CI/CD tools (e.g., Jenkins, GitLab CI) in lab scenarios.

CKAD Exam Preparation

Review the CKAD exam structure, including performance-based tasks, time constraints, and domain weightings.
Practice hands-on labs simulating exam scenarios, such as rapid application deployment and troubleshooting.
Master kubectl commands and YAML authoring for efficient task completion under exam conditions.
Develop time-management and debugging strategies to address complex development challenges effectively.
