## Source File
|
||||
- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/04_EKS/ctp-topic-70-eks-deployment-using-iac.md]]
|
||||
|
||||
## Summary
|
||||
- 核心主题:通过基础设施即代码(IaC)方式部署 EKS 集群
|
||||
- 问题域:EKS 集群部署方式、容器与虚拟机对比、自定义网络和自动扩展
|
||||
- 方法/机制:使用 Terraform 和 Service Catalog 两种 IaC 方式部署 EKS,ALB Ingress Controller 流量管理,EMI 自定义网络解决 CIDR 限制,Kubernetes Cluster Autoscaler 自动扩展
|
||||
- 结论/价值:EKS 提供完全托管的控制平面,支持零停机滚动部署和 IAM RBAC 最小权限访问
|
||||
|
||||
## Key Claims
|
||||
- EKS 是 AWS 提供的托管 Kubernetes 服务,具备完全托管的控制平面和工作节点自动扩展
|
||||
- 容器相比虚拟机具有更快的启动时间、内存效率和可移植性优势
|
||||
- 零停机滚动部署用于工作节点更新,IAM RBAC 映射实现最小权限访问
|
||||
- 自定义网络(EMI)解决 Pod 的 CIDR 限制问题
|
||||
|
||||
## Key Quotes
|
||||
> "EKS, a managed Kubernetes service by Amazon, offers features like fully managed control planes and autoscaling worker nodes."
|
||||
|
||||
> "The discussion begins with the differences between VMs and containers, highlighting the benefits of containers such as reduced boot time, memory efficiency, and portability."
|
||||
|
||||
## Key Concepts
|
||||
- [[Infrastructure as Code (IaC)]]:通过代码方式定义和管理基础设施
|
||||
- [[Kubernetes]]:用于弹性运行分布式系统的框架,支持自动化部署、回滚、负载均衡和 Pod 水平扩展
|
||||
- [[EKS]]:Amazon EKS,AWS 的托管 Kubernetes 服务
|
||||
- [[Terraform]]:HashiCorp 的 IaC 工具,用于定义 EKS 集群配置
|
||||
- [[Service Catalog]]:AWS 服务目录,用于创建和管理 EKS 集群
|
||||
- [[Cluster Autoscaler]]:Kubernetes 自动扩展器,根据资源需求自动扩展工作节点
|
||||
- [[ALB Ingress Controller]]:AWS 负载均衡器入口控制器,用于流量管理
|
||||
- [[CloudWatch]]:AWS 监控服务,结合 FluentBit 和 Container Insights 实现容器监控
|
||||
- [[FluentBit]]:日志转发器,以 DaemonSet 形式部署到 EKS 集群
|
||||
- [[Grafana]]:开源可视化平台,用于监控指标展示
|
||||
|
||||
## Key Entities
|
||||
- [[AWS]]:公有云平台,提供 EKS 服务
|
||||
- [[Terraform]]:IaC 工具供应商
|
||||
- [[Kubernetes]]:CNCF 开发的容器编排平台
|
||||
|
||||
