端口转发

微服务环境中，各个服务都通过 TCP / UDP 端口的形式提供访问。按调用者所在位置、通信协议的形式来划分，大致有如下几种情况：

调用者所在位置 通信协议 临时性 常见场景 推荐配置方式
VPC外 http / https 日常性 用户从互联网（亦可能是公司内网）
访问 web 页面，或者 restful 接口		 Kubernetes Ingress
（可在Kuboard中直接配置 互联网入口 ）
VPC外 tcp / udp 临时性 例如，开发者临时需要访问数据库端口、Redis端口等； 在客户端所在机器配置 kubectl，
并通过 kubectl port-forwad 进行端口转发
VPC外 tcp / udp 日常性 暂不讨论
VPC内/集群外 http / https 日常性 通过接口网关为周边系统提供服务 Kubernetes Service NodePort
（可在Kuboard中直接配置 访问方式/VPC内访问 ）
VPC内/集群外 tcp / udp 同上 同上
集群内 http / https 日常性 场景1：Web层访问微服务网关
场景2：微服务网关调用微服务，微服务之间的互相调用等。		 场景1：Kubernetes Service ClusterIP
（可在Kuboard中直接配置 访问方式/集群内访问 ）
场景2：Spring Cloud中使用Eureka/Consul等服务发现
（Kuboard中 访问方式/不配置 ）
集群内 tcp / udp 日常性 微服务访问数据库、微服务访问Redis等 Kubernetes Service ClusterIP

在作者使用 Kuboard 的运维实践中，有如下两个场景不能脱离 kubeadm / kubectl 命令行：

  • 初始化集群 / 向集群添加节点
  • 开发者临时需要访问数据库端口、Redis端口时，通过 kubectl port-forward 进行端口转发

Kuboard 计划实现类似 kubectl port-forward 的功能，提高问题诊断过程中的便利性。

    • 点击 删除容器组 按钮

      可删除该容器组。

      • 容器组被删除之后，Kubernetes Workload Controller 将要重新创建一个容器组，用于替代被删除的容器组；被删除容器组原有的状态将丢失，新容器组重新从 镜像中加载启动；

      • Kuboard 的工作负载编辑器，默认将容器组的 imagePullPolicy 设置为 Alwarys，因此，每次在容器组启动的时候，Kubenetes 都会尝试从镜像仓库中抓取最新镜像；

    image-20190722231246540

    诊断问题

    在诊断工作负载的问题时，Kuboard主要提供三种手段：

    事件： Kubernetes 部署相关问题

    如下图所示，图中提示

    错误内容：Error: ErrImagePull 该容器组抓取镜像失败

    失败原因：pull access denied for busy-box, repository does not exist or may require 'docker login'

    对于这样的错误，需要技术人员检查：

    • 容器所在节点与镜像仓库之间的网络连通性
    • 容器镜像拼写是否正确
    • 如果为私有仓库，是否在工作负载编辑器中正确配置了 docker 仓库用户名密码

    !> Kuboard 监听了 Kubernetes 集群的事件变化，您无需刷新页面，即可在工作负载编辑器的容器组界面区域看到该容器相关的最新事件。

    通过 Kubernetes 事件所指示出来的问题，通常是集群本身配置的问题，或者是创建工作负载时的参数填写问题，解决这样的问题需要的是 Kubernetes 集群相关的知识和背景，通常运维人员可以独立解决此类问题。

    日志所指示出来的错误，可能有两类原因：

    • 将其容器部署到 Kubernetes 时，参数配置填写错误
    • 容器内应用程序自身的 BUG

    无论是上述何种原因，运维人员如果请开发人员介入，一起排查这里问题，效果会好很多。

    终端： 通过交互式命令，在容器内诊断问题

    • 点击 终端 按钮

      可进入该容器的交互式命令界面

    image-20190722230511430

    适用场景

    在交互式终端里，运维人员可以：

    • 通过 ping / curl 等命令，测试网络连通性，测试 Kubernetes 的服务 DNS 解析是否正确
    • 通过 export 命令检查该容器的环境变量的设置是否正确

    开发人员 可以：

    • 通过 ls / cat / vi 等命令，查看该容器是否包含了最新的代码变更
    • 通过 vi 等命令，临时对容器中的配置文件进行修改，并在验证这种修改有效之后，才将其正式更新到代码库

    安装 Kuboard

    前提

    安装 Kuboard 时，假设您已经：

    • 已经有一个 Kubernetes 集群
    • 拥有对该 Kubernetes 集群执行 kubectl 命令时的所有权限

    如果没有 Kubernetes 集群，可以有如下选项：

    兼容性

    Kubernetes 版本 Kuboard 版本 兼容性 说明
    v1.15 v1.0.0-beta.10 😄 已验证
    v1.14 v1.0.0-beta.10 😄 已验证
    v1.13 v1.0.0-beta.10 😄 已验证
    v1.12 v1.0.0-beta.10 😐 Kubernetes Api v1.12 尚不支持 dryRun，
    忽略Kuboard在执行命令时的参数校验错误，可正常工作
    v1.11 v1.0.0-beta.10 😐 同上

    Kubernetes 安装方式

    • 部分用户使用二进制包的形式安装 Kubernetes，Kuboard 现在的版本不能在这类 Kubernetes 集群中正常工作，作者正在解决此问题。
    • 如果您是使用 kubeadm 安装的 Kubernetes 集群（Kubernetes 官方推荐的安装方式），请放心使用 Kuboard。
    • Kubeadm 相关资料请参考 https://kubernetes.io/docs/reference/setup-tools/kubeadm/kubeadm/

    安装

    获取并修改yaml文件

    wget https://raw.githubusercontent.com/eip-work/eip-monitor-repository/master/dashboard/kuboard.yaml

     安装 Kuboard
     
     前提
     
    安装 Kuboard 时，假设您已经：
     
    • 已经有一个 Kubernetes 集群
      •  
    • 拥有对该 Kubernetes 集群执行 kubectl 命令时的所有权限
     
    如果没有 Kubernetes 集群，可以有如下选项：
      
     兼容性
     
    Kubernetes 版本 Kuboard 版本 兼容性 说明
     
    v1.15 v1.0.0-beta.11 😄 已验证
     
    v1.14 v1.0.0-beta.11 😄 已验证
     
    v1.13 v1.0.0-beta.11 😄 已验证
     
    v1.12 v1.0.0-beta.11 😐 Kubernetes Api v1.12 尚不支持 dryRun，
    忽略Kuboard在执行命令时的参数校验错误，可正常工作
     
    v1.11 v1.0.0-beta.11 😐 同上
     
    如何确定我的 Kubernetes 是否可以安装 Kuboard？
     
    执行如下命令
     
    kubectl get pods -n kube-system -l 'component=kube-apiserver'
+
    如果查询结果中至少有一个容器组处于 Running 状态，则 Kuboard 可以完美地运行在您的 Kubernetes 集群上。

    移除 worker 节点

    正常情况下，您无需移除 worker 节点，如果添加到集群出错，您可以移除 worker 节点，再重新尝试添加

    在准备移除的 worker 节点上执行

    kubeadm reset

    在 master 节点 demo-master-a-1 上执行

    kubectl delete node demo-worker-x-x
    • 将 demo-worker-x-x 替换为要移除的 worker 节点的名字
    • worker 节点的名字可以通过在节点 demo-master-a-1 上执行 kubectl get nodes 命令获得

    Ingress官方文档：https://kubernetes.io/docs/concepts/services-networking/ingress/

    Ingress Controllers官网介绍：https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/

    本文中使用如下部署方式：https://kubernetes.github.io/ingress-nginx/deploy/baremetal/#using-a-self-provisioned-edge

    kubernetes支持多种Ingress Controllers，本文推荐使用 https://github.com/nginxinc/kubernetes-ingress

    在 demo-master-a-1 上执行

    kubectl apply -f https://raw.githubusercontent.com/eip-work/eip-monitor-repository/master/dashboard/nginx-ingress.yaml

    配置域名解析

    将域名 *.demo.yourdomain.com 解析到 demo-worker-a-2 的 IP 地址 z.z.z.z （也可以是 demo-worker-a-1 的地址 y.y.y.y）

    由于需要申请域名，过程会比较繁琐，有如下两种替代方案：

    • 在您的客户端机器（访问部署在K8S上的 web 应用的浏览器所在的机器）设置 hosts 配置；
    • 暂时放弃域名的配置，临时使用 NodePort 或者 kubectl port-forward 的方式访问部署在 K8S 上的 web 应用

    验证配置

    在浏览器访问 a.demo.yourdomain.com，将得到 404 NotFound 错误页面

    ​ 更为贴心的，当某一个工作负载存在部署方面的问题时， Kuboard 将以红色高亮出该工作负载，并配有合适的方式辅助用户定位错误信息。

    无需手写 Yaml

    ​ 学习 Kubernetes 时，需要花费许多的时间，在理解一个概念之后，模仿着写一个 yaml 文件，再使用 kubectl 应用该文件。

    ​ 使用 Kuboard 提供的工作负载编辑器，可以直观的完成应用的部署

    Kubernetes 日常运维人员

    ​ kubectl 的命令敲了许多遍了？yaml 文件越来越多，结构越来越复杂？又要部署一套测试环境，用来进行 UAT 测试？

    纯图形界面运维 Kubernetes

    在作者的日常运维工作中，除了 kubectl port-forward 还需要回到命令行界面以外，其他运维任务已经全部在 Kuboard 中轻松完成。更让人期待的是，Kuboard 作者还计划实现 port-forward 的功能，如此一来，作者日后就完全不再需要使用 kubectl 了。

    多环境复制

    为了能够是你的一套 yaml 文件适应多种部署（开发环境、测试环境、UAT环境、生产环境），您一定尝试过各种办法，例如 helmer chart, kustomize, kubectl apply -k directory_name，但是您本来可以更轻松地完成这样的任务的。

    Kuboard 提供了 工作负载导出和导入的功能，0 yaml文件，轻松复制多个环境。

    应用升级

    Kuboard 提供批量修改容器镜像版本的功能，轻松升级应用程序的版本。

    0 侵入性

    ​ Rancher 为了支持多云管理（MeSos，Docker Swarm，Kubernetes等），引入了一系列复杂的概念，又需要新增安装 Rancher Server、Rancher Agent等，本来学习 Kubernetes 已然不堪重负，Rancher再把多云整合到一起来，无疑又增加了学习和使用的复杂性。如果您只是打算使用 Kubernetes 的话，也许并不需要选择 Rancher 这样重量级的产品。Kuboard 仅仅依赖于原生 Kubernetes，可以运行在各种公有云、私有云上，您也可以自己基于物理机、vsphere、vmware等已经有的基础设施搭建 Kubernetes，轻松实现现有 Infrastructure 的容器化改造。
