## EFK ## EFK
`EFK` 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]()；Elasticsearch 是日志存储和日志搜索引擎，Fluentd 负载把`k8s`集群的日志发送给 Elasticsearch, Kibana 是可视化界面查看和检索存储在 Elasticsearch 的数据。
### 部署
下载官方最新[release](https://github.com/kubernetes/kubernetes/release)，进入目录: `kubernetes/cluster/addons/fluentd-elasticsearch`，参考官方配置的基础上使用本项目`manifests/efk/`部署，以下为几点主要的修改：
+ 官方提供的`kibana-deployment.yaml`中的参数`SERVER_BASEPATH`在k8s v1.8 版本以后部署需要按照本项目调整
+ 修改官方docker镜像，方便国内下载加速
请使用`kubectl create -f /etc/ansible/manifests/efk/`进行安装
注意：Fluentd 是以 DaemonSet 形式运行且只会调度到有`beta.kubernetes.io/fluentd-ds-ready=true`标签的节点，所以对需要收集日志的节点逐个打上标签：
``` bash
$ kubectl label nodes 192.168.1.2 beta.kubernetes.io/fluentd-ds-ready=true
node "192.168.1.2" labeled
```
### 验证
``` bash
kubectl get pods -n kube-system|grep -E 'elasticsearch|fluentd|kibana'
elasticsearch-logging-0 1/1 Running 0 19h
elasticsearch-logging-1 1/1 Running 0 19h
fluentd-es-v2.0.2-6c95c 1/1 Running 0 17h
fluentd-es-v2.0.2-f2xh8 1/1 Running 0 8h
fluentd-es-v2.0.2-pv5q5 1/1 Running 0 8h
kibana-logging-d5cffd7c6-9lz2p 1/1 Running 0 1m
```
kibana Pod 第一次启动时会用较长时间(10-20分钟)来优化和 Cache 状态页面，可以查看 Pod 的日志观察进度，等待 `Ready` 状态
``` bash
$ kubectl logs -n kube-system kibana-logging-d5cffd7c6-9lz2p -f
...
{"type":"log","@timestamp":"2018-03-13T07:33:00Z","tags":["listening","info"],"pid":1,"message":"Server running at http://0:5601"}
{"type":"log","@timestamp":"2018-03-13T07:33:00Z","tags":["status","ui settings","info"],"pid":1,"state":"green","message":"Status changed from uninitialized to green - Ready","prevState":"uninitialized","prevMsg":"uninitialized"}
```
### 访问 Kibana
这里介绍 `kube-apiserver`方式访问，获取访问 URL
``` bash
$ kubectl cluster-info | grep Kibana
Kibana is running at https://192.168.1.10:8443/api/v1/namespaces/kube-system/services/kibana-logging/proxy
```
浏览器访问 URL：`https://192.168.1.10:8443/api/v1/namespaces/kube-system/services/kibana-logging/proxy`，然后使用`basic auth`或者`证书` 的方式认证后即可，关于认证可以参考[dashboard文档](dashboard.md)
首次登陆需要在`Management` - `Index Patterns` 创建 `index pattern`，可以使用默认的 logstash-* pattern，点击 Create; 创建Index后，稍等几分钟就可以在 Discover 菜单看到 ElasticSearch logging 中汇聚的日志；

containers.input.conf: |-
# This configuration file for Fluentd / td-agent is used
# to watch changes to Docker log files. The kubelet creates symlinks that
# capture the pod name, namespace, container name & Docker container ID
# to the docker logs for pods in the /var/log/containers directory on the host.
# If running this fluentd configuration in a Docker container, the /var/log
# directory should be mounted in the container.
#
# These logs are then submitted to Elasticsearch which assumes the
# installation of the fluent-plugin-elasticsearch & the
# fluent-plugin-kubernetes_metadata_filter plugins.
# See https://github.com/uken/fluent-plugin-elasticsearch &
# https://github.com/fabric8io/fluent-plugin-kubernetes_metadata_filter for
# more information about the plugins.
#
# Example
# =======
# A line in the Docker log file might look like this JSON:
#
# {"log":"2014/09/25 21:15:03 Got request with path wombat\n",
# "stream":"stderr",
# "time":"2014-09-25T21:15:03.499185026Z"}
#
# The time_format specification below makes sure we properly
# parse the time format produced by Docker. This will be
# submitted to Elasticsearch and should appear like:
# $ curl 'http://elasticsearch-logging:9200/_search?pretty'
# ...
# {
# "_index" : "logstash-2014.09.25",
# "_type" : "fluentd",
# "_id" : "VBrbor2QTuGpsQyTCdfzqA",
# "_score" : 1.0,
# "_source":{"log":"2014/09/25 22:45:50 Got request with path wombat\n",
# "stream":"stderr","tag":"docker.container.all",
# "@timestamp":"2014-09-25T22:45:50+00:00"}
# },
# ...
#
# The Kubernetes fluentd plugin is used to write the Kubernetes metadata to the log
# record & add labels to the log record if properly configured. This enables users
# to filter & search logs on any metadata.
# For example a Docker container's logs might be in the directory:
#
# /var/lib/docker/containers/997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b
#
# and in the file:
#
# 997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b-json.log
#
# where 997599971ee6... is the Docker ID of the running container.
# The Kubernetes kubelet makes a symbolic link to this file on the host machine
# in the /var/log/containers directory which includes the pod name and the Kubernetes
# container name:
#
# synthetic-logger-0.25lps-pod_default_synth-lgr-997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b.log
# ->
# /var/lib/docker/containers/997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b/997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b-json.log
#
# The /var/log directory on the host is mapped to the /var/log directory in the container
# running this instance of Fluentd and we end up collecting the file:
#
# /var/log/containers/synthetic-logger-0.25lps-pod_default_synth-lgr-997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b.log
#
# This results in the tag:
#
# var.log.containers.synthetic-logger-0.25lps-pod_default_synth-lgr-997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b.log
#
# The Kubernetes fluentd plugin is used to extract the namespace, pod name & container name
# which are added to the log message as a kubernetes field object & the Docker container ID
# is also added under the docker field object.
# The final tag is:
#
# kubernetes.var.log.containers.synthetic-logger-0.25lps-pod_default_synth-lgr-997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b.log
#
# And the final log record look like:
#
# {
# "log":"2014/09/25 21:15:03 Got request with path wombat\n",
# "stream":"stderr",
# "time":"2014-09-25T21:15:03.499185026Z",
# "kubernetes": {
# "namespace": "default",
# "pod_name": "synthetic-logger-0.25lps-pod",
# "container_name": "synth-lgr"
# },
# "docker": {
# "container_id": "997599971ee6366d4a5920d25b79286ad45ff37a74494f262e3bc98d909d0a7b"
# }
# }
#
# This makes it easier for users to search for logs by pod name or by
# the name of the Kubernetes container regardless of how many times the
# Kubernetes pod has been restarted (resulting in a several Docker container IDs).
# Json Log Example:
# {"log":"[info:2016-02-16T16:04:05.930-08:00] Some log text here\n","stream":"stdout","time":"2016-02-17T00:04:05.931087621Z"}
