Kubernetes HPA控制器

一、pod扩容

1.1、pod自动升缩

根据当前pod的负载，动态调整 pod副本数量，业务高峰期自动扩容pod的副本数以尽快响应pod的请求。
在业务低峰期对pod进行缩容，实现降本增效的目的。
公有云支持node级别的弹性伸缩。

1.2、手动调整pod副本数

[root@easzlab-deploy ~]# kubectl get pod -n magedu

[root@easzlab-deploy ~]# kubectl --help |grep scale #查看命令帮助

1.3、动态伸缩控制器类型

水平pod自动缩放器(HPA)：

基于pod 资源利用率横向调整pod副本数量。

垂直pod自动缩放器(VPA)：

基于pod资源利用率，调整对单个pod的最大资源限制，不能与HPA同时使用。

集群伸缩(Cluster Autoscaler,CA)

基于集群中node 资源使用情况，动态伸缩node节点，从而保证有CPU和内存资源用于创建pod。

二、HPA控制器

2.1、HPA控制器简介

Horizontal Pod Autoscaling (HPA)控制器，根据预定义好的阈值及pod当前的资源利用率，自动控制在k8s集群中运行的pod数量(自动弹性水平自动伸缩).
--horizontal-pod-autoscaler-sync-period #默认每隔15s(可以通过– horizontal-pod-autoscaler-sync-period修改)查询metrics的资源使用情况。
--horizontal-pod-autoscaler-downscale-stabilization #缩容间隔周期，默认5分钟。
--horizontal-pod-autoscaler-sync-period #HPA控制器同步pod副本数的间隔周期
--horizontal-pod-autoscaler-cpu-initialization-period #初始化延迟时间，在此时间内 pod的CPU 资源指标将不会生效，默认为5分钟。
--horizontal-pod-autoscaler-initial-readiness-delay #用于设置 pod 准备时间，在此时间内的 pod 统统被认为未就绪及不采集数据,默认为30秒。
--horizontal-pod-autoscaler-tolerance #HPA控制器能容忍的数据差异(浮点数，默认为0.1)，即新的指标要与当前的阈值差异在0.1或以上,即要大于1+0.1=1.1，或小于1-0.1=0.9，比如阈值为CPU利用率50%,当前为80%,那么80/50=1.6 > 1.1则会触发扩容，反之会缩容。即触发条件： avg(CurrentPodsConsumption) / Target >1.1 或 <0.9=把N个pod的数据相加后根据pod的数量计算出平均数除以阈值,大于1.1就扩容，小于0.9就缩容。
计算公式： TargetNumOfPods = ceil(sum(CurrentPodsCPUUtilization) / Target) #ceil是一个向上取整的目的pod整数。
指标数据需要部署metrics-server，即HPA使用metrics-server作为数据源。
https://github.com/kubernetes-sigs/metrics-server
在k8s 1.1引入HPA控制器，早期使用Heapster组件采集pod指标数据，在k8s 1.11版本开始使用Metrices Server完成数据采集，然后将采集到的数据通过API（Aggregated API，汇总API），例如metrics.k8s.io、 custom.metrics.k8s.io、 external.metrics.k8s.io，然后再把数据提供给HPA控制器进行查询，以实现基于某个资源利用率对pod进行扩缩容的目的。

2.2、metrics-server 部署

Metrics Server 是 Kubernetes 内置的容器资源指标来源。
Metrics Server 从node节点上的 Kubelet 收集资源指标,并通过Metrics API在 Kubernetes apiserver 中公开指标数据,以供Horizontal Pod Autoscaler和Vertical Pod Autoscaler使用,也可以通过访问kubectl top node/pod 查看指标数据。

[root@easzlab-deploy kube-state-metrics]# wget https://github.com/kubernetes-sigs/metrics-server/releases/download/metrics-server-helm-chart-3.8.2/components.yaml
