Kubernetes: Do Básico ao Avançado

Unlock Kubernetes Mastery: A Comprehensive On-Premises Training

Feeling overwhelmed by Kubernetes? Do you grasp the concepts but struggle to apply them in real-world scenarios? This course provides a solid foundation in Kubernetes designed for practical application. We focus exclusively on Kubernetes on-premises, allowing you to build and manage your own cluster without incurring cloud computing costs. Gain complete control over your infrastructure and master the core principles of container orchestration.

Here's a detailed curriculum to elevate your Kubernetes skills:

• Cluster Creation: Learn Kubernetes architecture and create clusters using three popular methods: Kind, Vagrant, and Kubespray. We'll also cover essential topics like kubeconfig, general commands, communication debugging, and etcd usage.
• YAML Mastery: Understand YAML structure and effectively deploy applications to the API server using kubectl. Discover productivity-boosting tips for daily YAML usage.
• Namespaces: Isolate applications for improved organization and security using Kubernetes namespaces.
• Pods: Explore the fundamental building block of Kubernetes. Dive deep into init containers, multi-container pods, static pods, lifecycle management, and troubleshooting techniques.
• Deployments: Master Deployments for reliable application management. Learn about labels & selectors, rollout control, optimization strategies, scaling, resource definition, health checks (probes), and environment variables.
• DaemonSets: Understand the use cases for DaemonSets compared to Deployments.
• StatefulSets: Differentiate between stateless and stateful applications and learn when to effectively utilize StatefulSets.
• Jobs & CronJobs: Deploy single-execution workloads using Jobs and scheduled tasks with CronJobs.
• Services: Expose applications and balance traffic using various Service types. Learn to debug at the iptables level to understand kube-proxy's rule management.
• Ingress: Expose applications externally using Ingress and configure NGINX as your Ingress controller.
• ConfigMaps & Secrets: Externalize configuration files and sensitive information using ConfigMaps and Secrets.
• Storage: Learn to persist data using StorageClasses, Persistent Volumes (PVs), and Persistent Volume Claims (PVCs), ensuring data durability even when containers are recreated.
• Autoscaling: Implement horizontal pod autoscaling (HPA) to automatically scale your application based on resource utilization. Understand the calculation formula and explore vertical pod autoscaling (VPA).
• Networking: Understand the CNI (Container Network Interface) and CoreDNS components responsible for network implementation and DNS queries. Master troubleshooting and debugging network issues.
• RBAC (Role-Based Access Control): Secure your Kubernetes cluster by configuring user authentication with TLS x509 certificates and authorizing API calls using RBAC.
• Upgrade: Perform pre-upgrade checks and execute manual node upgrades for seamless cluster maintenance.
• Scheduling: Utilize various scheduling strategies including NodeAffinity, PodAffinity, NodeSelector, Topology Constraints, Taints, and Tolerations to control pod placement.
• Troubleshooting: Develop expert-level troubleshooting skills. Learn to analyze common problems and simulate connectivity errors using iptables. Gain practical analysis strategies used daily.

This comprehensive training focuses on a deep understanding of the Kubernetes ecosystem, preparing you for success in the job market. It's not about building projects; it's about mastering the underlying concepts for real-world application.
