Kubernetes (Kubernetes  K8s), còn được viết tắt là K8s, là hệ thống quản lý container mã nguồn mở nổi bật nhất hiện nay. Dự án này ban đầu được Google phát triển, phát hành lần đầu tiên vào năm 2014, và hiện do Cloud Native Computing Foundation (CNCF) quản lý. Mã nguồn được viết bằng Go, phát hành theo Apache License 2.0, lưu trữ tại github.com/kubernetes/kubernetes.

Kubernetes được thiết kế để triển khai, mở rộng quy mô, vận hành và quản lý các container theo cơ chế tự động hóa và khai báo cấu hình (container orchestration engine).

Kubernetes có 10 chức năng cốt lõi chính:

Cân bằng tải & Service discovery: Tạo tên miền DNS hoặc IP riêng, tự động phân phối lưu lượng.

Điều phối lưu trữ: Tích hợp được ổ cứng cục bộ, dịch vụ lưu trữ đám mây như cloud server.

Triển khai & hoàn nguyên tự động: Tự điều chỉnh hệ thống theo trạng thái mong muốn.

Tối ưu phân bổ tài nguyên: Gán CPU, RAM cho container, sắp xếp tự động trên cluster.

Tự động phục hồi: Tự restart container lỗi, thay thế, loại bỏ container không phản hồi.

Quản lý cấu hình & secret: Lưu trữ token OAuth, SSH key, mật khẩu mà không lộ trong cấu hình stack.

Xử lý theo lô: Hỗ trợ các job batch, quy trình CI/CD.

Tự mở rộng ngang: Tăng giảm container qua CLI, giao diện, hoặc tự động theo tài nguyên.

Hỗ trợ Dual-stack IPv4/IPv6: Cấp phát địa chỉ cho Pod và Service.

Thiết kế mở rộng: Thêm tính năng mà không cần chỉnh sửa mã nguồn gốc.


Cách thức hoạt động của K8s:
Kubernetes K8s hoạt động theo kiến trúc cluster (cụm kiến trúc), chia thành Master Node (API Server, Scheduler, Controller Manager, Etcd) và Worker Node – nơi chạy các Pods. Mỗi Pod chứa 1 hay nhiều container chia sẻ network, storage, hostname. Các Deployment, Replication Controller, Service, Kubelet, Kubectl, Image, Label... là những thành phần quan trọng giúp tự động hóa toàn bộ vòng đời container.

K8s liên tục giám sát, tự scale khi cần, phân bổ tài nguyên thông minh và giảm thiểu lỗi thủ công.

Madhu Sudhan Subedi Tech Weekly - Twenty One Episode

Today we dive deep into the mystery of Kubernetes installation, specifically OpenShift installation. We help explain why Kubernetes installs look so weird compared to traditional operations, install processes, and where are the playbooks? Where are the scripts? Are the runbooks describing all the steps you need to take? All of it seems to be missing, and in this podcast, we explain why.

Today we tackle the generational infrastructure shift that's keeping IT leaders awake at night: OpenShift virtualization adoption. We dig deep into why organizations are struggling to migrate from traditional VM-focused infrastructure to Kubernetes-managed infrastructure. We explore the real hurdles blocking this transition and unpack the strategic positioning that matters when you're moving to container-orchestrated infrastructure. This isn't about dumping everything into Kubernetes and calling it done, we examine what it really takes to use Kubernetes as your infrastructure abstraction layer while navigating the operational realities that make or break these migrations.
