EFK 收集 K8S 容器日志
日志在生产环境中非常重要，可以帮助我们排查问题，分析业务问题，分析用户行为等。
对于单机版的集群式应用来说，如果遇到故障我们可以登录上服务器上通过查看日志文件的方式进行查看日志，但对多规模的分布式多节点应用来说，日志分散在多个节点，这显然通过登录上每个节点服务器通过命令查看日志不可取的，就需要统一的日志管理平台收集各各节点上的日志集中管理系统。ELK stack 就是一款日志收集、处理、搜索、分析的成熟的管理系统。
一、ELK简介：
ELK是三个开源软件的缩写，分别为：Elasticsearch 、 Logstash以及Kibana , 它们都是开源软件。不过现在还新增了一个Beats，它是一个轻量级的日志收集处理工具(Agent)，Beats占用资源少，适合于在各个服务器上搜集日志后传输给Logstash，官方也推荐此工具，目前由于原本的ELK Stack成员中加入了 Beats 工具所以已改名为Elastic Stack。
Elasticsearch 主要负责日志存储，索引，分片，搜索等
Logstash 主要负责日志的收集，日志处理，是一个重量级的组件。随后就有Fluentd出现，相比它更易用、资源消耗更少、性能更高，在数据处理上更高效可靠，受到企业欢迎。

二、监控方案
日志管理如果手动处理，可以使用kubectl log -n 名称空间 pod名 (kubectl log -f -n 名称空间 pod名)动态查看日志。但是在集群情况下，由于节点数量多，环境复杂，pod的生命周期等特性，是手动查看日志不现实，而使用 elkstack收集日志我们有两种方案：
| 方案 | 方式 |
|---|---|
| 方案一 | 每个容器中集成日志收集工具 |
| 方案二 | 每个pod中运行两个容器，一个业务主容器，一个日志收集容器 |
| 方案三 | 直接从k8s 宿主机中获取容器日志 【官方推荐】本次测试方案 |
日志收集工具方案:
- Logstash 占内存不推荐使用
- filebeat 轻量15M左右
- fluentd 每台节点运行一个进程，本次测试方案
三、监控原理
k8s集群中的pod产生的日志（stdout/stderr）都存放在对应node的/var/lib/docker/containers/下，使用fluentd的pod，以deamonset形式运行在各个节点之上收集所有pod的日志
四、安装方式
k8s是一个 容器的编排平台，而在k8s之上我们运行的是pod。那么EFK这套环境也运行在k8s上面。elasticsearch是日志收集存储的，在k8s之上我们要使用存储卷来保证数据的稳定性，为了保证eslaticsearch的稳定性，我们采用分角色集群(mast/data/client)。fluentd 需要运行在每台node节点(包括master节点)之上，且每个节点只能运行一个服务，我们采用deamonset控制器控制pod。kibana只是eslasticsearch的web客户端，小规模的集群我们使用deployment运行一个副本即可。运行pod我们需要yml格式的资源清单文件，为了方便起见我们使用helm进行安装。

5.4 elasticsearch 集群角色
stable 官方提供的 elasticsearch 集群配置，是将elasticsearch 按角色做集群，在生产环境下，如果不修改elasticsearch节点的角色信息，在高数据量，高并发的场景下集群容易出现脑裂等问题。
默认情况下，elasticsearch集群中每个节点都有成为主节点的资格，也都存储数据，即双重角色。
由两个属性控制：node.master和node.data，默认情况下这两个属性的值都是true，及既是master 又是data
elasticsearch 集群的三个角色:
- master 负责成为主节点，维护整个集群的状态
- data 负责存储数据,后期提供存储和查询服务,分片
- client 海量请求的时候可以进行负载均衡

# efk 是一组组件，负责我们整个k8s集群的日志管理。为了便于后期的管理，我们新建一个efk的名称空间，将efk集群运行于efk名称空间中

NOTES:
The elasticsearch cluster has been installed.
Elasticsearch can be accessed:
* Within your cluster, at the following DNS name at port 9200:
elstest-elasticsearch-client.efk.svc
* From outside the cluster, run these commands in the same shell:
export POD_NAME=$(kubectl get pods --namespace efk -l "app=elasticsearch,component=client,release=elstest" -o jsonpath="{.items[0].metadata.name}")
echo "Visit http://127.0.0.1:9200 to use Elasticsearch"

八、安装过程中的坑
8.1 helm 仓库地址
问题：
默认情况下的 helm stable版本是google的地址，google的地址再国内无法访问，或时而无法访问。这钟情况下helm仓库使用的第一步就卡死了。
https://kubernetes-charts.storage.googleapis.com/
解决方案：
-
阿里云helm仓库代理
地址:https://aliacs-app-catalog.oss-cn-hangzhou.aliyuncs.com/charts/
已经好久没有更新过了 -
翻墙
linux 使用vpn 或ss -
内部仓库–git
github官方地址: https://github.com/helm/charts.git -
本地文件–git [详情加helm 进阶文档]
helm serve --address 0.0.0.0:8080 --repo-path /app/dcos/chart-repo
helm repo index /app/dcos/chart-repo
- 第三方代理
代理地址: https://burdenbear.github.io/kube-charts-mirror/
代理工具地址： https://github.com/taowujie/kube-charts-mirror
8.2 访问国外gcr docker镜像
问题:
gcr docker镜像 是google的docker仓库镜像，国内无法访问。无论是后期软件 合适kubeadm安装kubernetes 集群都是一个卡点。
解决方案:
- 方案一 国内加速镜像 https://github.com/anjia0532/gcr.io_mirror
gcr.io/namespace/image_name:image_tag
#eq
gcr.azk8s.cn/namespace/image_name:image_tag
#替换方式---> 微软云国内加速镜像
-
方案二 自己通过 Dockerfile 制作镜像 利用dockerhub生成
（https://blog.csdn.net/weixin_39961559/article/details/80739352
https://blog.csdn.net/qq_27028561/article/details/79064414
https://blog.csdn.net/nklinsirui/article/details/80581286 ） -
方案三 vpn 代理
-
方案四 使用第三方镜像 安全性无法保障
docker search xx
8.3 kibana 无法启动
查看日志:
"message":"child \"elasticsearch\" fails because [\"hosts\" is not allowed]"
官方charts 文件bug，版本es 6.5 版本
url链接:
https://github.com/helm/charts/issues/14062
https://github.com/elastic/kibana/issues/32303
8.4 kibana 不兼容 es
问题:
Kibana server is not ready yet
排查思路
- kibana版本要和elasticsearch版本相同
- elasticsearch 集群状态不正常。
使用kubectl log xxpod名查看日志
8.5 fluentd 无法收集日志到es中
启动正常就是es上面没有日志索引。
原因:
fluentd 的镜像保存在grc docker 仓库中，国内无法访问。起初使用的是第三方镜像，是版本不兼容造成的。
九、优缺点
Kubernetes官方提供了EFK的日志收集解决方案，但是这种方案并不适合所有的业务场景，它本身就有一些局限性，例如：
所有日志都必须是out前台输出，真实业务场景中无法保证所有日志都在前台输出
只能有一个日志输出文件，而真实业务场景中往往有多个日志输出文件
Fluentd并不是常用的日志收集工具，我们更习惯用logstash，现使用filebeat替代
我们已经有自己的ELK集群且有专人维护，没有必要再在kubernetes上做一个日志收集服务
基于以上几个原因，我们决定使用自己的ELK集群。
| 编号 | 方案 | 优点 | 缺点 |
|---|---|---|---|
| 1 | 每个app的镜像中都集成日志收集组件 | 部署方便，kubernetes的yaml文件无须特别配置，可以为每个app自定义日志收集配置 | 强耦合，不方便应用和日志收集组件升级和维护且会导致镜像过大 |
| 2 | 单独创建一个日志收集组件跟app的容器一起运行在同一个pod中 | 低耦合，扩展性强，方便维护和升级 | 需要对kubernetes的yaml文件进行单独配置，略显繁琐 |
| 3 | 将所有的Pod的日志都挂载到宿主机上，每台主机上单独起一个日志收集Pod | 完全解耦，性能最高，管理起来最方便 | 需要统一日志收集规则，目录和输出方式 |
