简单介绍：

EFK 组合插件是k8s项目的一个日志解决方案，它包括三个组件：Elasticsearch, Fluentd, Kibana。相对于ELK这样的架构，k8s官方推行了EFK，可能Fluentd相对于Logstash更加轻量级吧。

Elasticsearch 是日志存储和日志搜索引擎，Fluentd 负责把k8s集群的日志发送给 Elasticsearch, Kibana 则是可视化界面查看和检索存储在 Elasticsearch 的数据。

GitHub官网：https://github.com/kubernetes/kubernetes/tree/master/cluster/addons/fluentd-elasticsearch

特别补充：

Kubernetes官方推荐的EFK组合，其实对于我们大多数公司来说并不合适，其中一点原因就是这个组合需要应用日志打印到标准输出。

推荐做法：还是使用传统的ELK组合，ELK可以部署在K8S集群之外，日志写入指定存储目录文件中，并采用filebeat方式采集。

测试环境：

System Hostname IP
CentOS 7.6 k8s-master 138.138.82.14
CentOS 7.6 k8s-node1 138.138.82.15
CentOS 7.6 k8s-node2 138.138.82.16

注：以下是简单的安装部署操作，实际用于生产环境的话还要根据不同的后端存储进而修改yaml中的相应存储路径。

操作步骤：

1. 获取yaml文件

从github官网下载：https://github.com/kubernetes/kubernetes/tree/master/cluster/addons/fluentd-elasticsearch

或者下载整个tar包：https://storage.googleapis.com/kubernetes-release/release/v1.14.1/kubernetes-server-linux-amd64.tar.gz

解压后yanl文件位置： kubernetes/cluster/addons/fluentd-elasticsearch/

复制yaml文件到另一处进行修改操作：

[root@k8s-master ~]# mkdir efk

[root@k8s-master ~]# cp kubernetes/cluster/addons/fluentd-elasticsearch/*.yaml  efk/

[root@k8s-master ~]# cd efk/

[root@k8s-master efk]# ll

总用量 36

-rw-r--r-- 1 root root   382 5月   5 13:55 es-service.yaml

-rw-r--r-- 1 root root  2906 5月   5 14:44 es-statefulset.yaml

-rw-r--r-- 1 root root 16124 5月   5 13:55 fluentd-es-configmap.yaml

-rw-r--r-- 1 root root  2702 5月   5 13:55 fluentd-es-ds.yaml

-rw-r--r-- 1 root root  1052 5月   5 13:55 kibana-deployment.yaml

-rw-r--r-- 1 root root   354 5月   5 13:55 kibana-service.yaml

2. 准备镜像（在所有主机上）

注：因为被墙的缘故，加上镜像文件比较大，启动会费时，可以提前单独下载好所需镜像。

①修改 es-statefulset.yaml （https://www.docker.elastic.co/#）

②修改 fluentd-es-ds.yaml

③无需修改 kibana-deployment.yaml

说明：关于kibana镜像以-oss结尾的版本好奇（default release that contains the commercially licensed code. The release that contains only open source will have the -oss appended to it.）：

https://www.elastic.co/guide/en/kibana/6.0/docker.html

https://discuss.elastic.co/t/what-are-the-differences-between-the-kibana-oss-and-non-oss-build/152364/3

附上镜像拉取文本：

~]# docker pull docker.elastic.co/elasticsearch/elasticsearch:6.6.

~]# docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/fluentd-elasticsearch:v2.4.0

~]# docker pull docker.elastic.co/kibana/kibana-oss:6.6.

3. 发布yaml文件到k8s中

[root@k8s-master efk]# kubectl apply -f .

4. 查看各pod状态

[root@k8s-master efk]# kubectl get po -n kube-system -o wide

顺利的话，稍等一小会就成功running状态了。如果有问题，就查看容器日志，基本上可以定位到所有错误原因。

5. 查看kibana

留意kibana的日志输出，这里给出我的实际一段：
