k8s install PostgreSQL StatefulSet

In the following set of exercises StatefulSets are presented in a practical manner. The PostgreSQL [11] RDBMS is used as an example as the database is both widely known and of great utility to any developer. The goal of the exercises are not to build a production grade automation for PostgreSQL but to illustrate StatefulSet concepts. Designing the StatefulSet In order to create the PostgreSQL StatefulSet we proceed with the following steps: Identify or build (a) container image(s) Specify a headless Service Specify a StatefulSet Provision the Service and StatefulSet Conduct simple experiments Start with finding a container image. The Container Image An essential part of the StatefulSet for PostgreSQL is the database server itself. Luckily, there is no need to containerize PostgreSQL as this as already been done. Hence, use the official PostgreSQL Docker Image found at Docker Hub [1].……

k8s调度深入刨析

调度程序决定 pod 在集群中的部署位置,这听起来像是一项简单的工作,但它相当复杂!当使用 kubectl 提交部署时,API 服务器会收到请求,并将资源存储在 etcd 中。 一、谁创建了 Pod? 一个常见的误解是创建 pod 是调度程序的工作。相反,控制器管理器创建它们(以及关联的 ReplicaSet)。 此时,pod 在 etcd 中……

AWS ECS-EKS-Fargate

Amazon Web Services (AWS) provides more than 200 services. Among those, Amazon Elastic Compute Service (ECS), Elastic Kubernetes Service (EKS), and AWS Fargate help deploy and manage containers. Choosing between these services can be challenging. They seem similar on the surface (and are all popular). But each offers unique benefits and limitations. In this guide, we compare the three services, discussing the best use cases for each, and helping you choose the best fit for your business. How To Compare ECS Vs. EKS Vs. Fargate To understand how EKS, ECS, and Fargate differ, consider how AWS’s container services are organized. AWS Registry services enable you to store and manage container images. Amazon Elastic Container Registry (ECR) is in this category. AWS Orchestration services let you manage where and when your containers run. The two services in this category are Amazon ECS and Amazon EKS.……
