Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications.
Kubernetes consists of several key components, including the master node (control plane) and worker nodes, which collectively manage and run containerized applications. Other components include etcd, kubelet, kube-proxy, and various controllers.
Kubernetes offers benefits such as scalability, fault tolerance, automated application deployment and management, efficient resource utilization, service discovery, and rolling updates, making it easier to manage and scale applications in a distributed environment.
No, the learning path includes a course called "Docker Basics - Containerization" that covers the fundamentals of containers, making it suitable for beginners.
It depends on your career goals. CKA (Certified Kubernetes Administrator) focuses on cluster administration, while CKAD (Certified Kubernetes Application Developer) targets application deployment and management. Choose based on your interests and job requirements.
Helm is a popular package manager for Kubernetes, which simplifies application deployment. It is widely used and recommended for managing complex applications on Kubernetes, making it beneficial to learn.
Istio provides advanced networking capabilities for microservices running on Kubernetes, offering features like traffic management, observability, and security. It is highly relevant for managing distributed systems.
Monitoring is crucial for observing the health and performance of Kubernetes clusters and applications. Prometheus is a widely used monitoring toolkit specifically designed for Kubernetes.
