Filbeat采集nginx-ingress日志

　　一、创建configmap配置文件

　　注：filebeat6以上版本需要将prospectors改为inputs，paths下指定的nginx-ingress日志路径匹配模式以及hosts指定的kafka地址需要根据实际修改，document_type和topic需要是kafka中存在的

[root@localhost ~]# cat >> filebeat-config.yaml <<EOF
> apiVersion: v1
> data:
> filebeat.yml: |
> filebeat.prospectors:
> - input_type: log
> paths:
> - "/var/log/containers/nginx-ingress-ingress-nginx-controller-*_ingress-nginx_controller-*.log"
> symlinks: true
> json.message_key: log
> json.keys_under_root: true
> json.add_error_key: true
> multiline.pattern: '^\s'
> multiline.match: after
> document_type: k8s-logs
> fields:
> POD_NAME: 'nginx-ingress'
> fields_under_root: true
> exclude_lines: ['\.(xml|gif|jpg|jpeg|png|bmp|swf|woff|woff2|ttf|js|css|svg|ico)']
>
>
> output.kafka:
> hosts: ["kafka-service:9092"]
> topic: "k8s-logs"
> required_acks: 1
> kind: ConfigMap
> metadata:
> name: filebeat-configmap
> namespace: middleware
> EOF

　　二、创建configmap

[root@develop-k8s-worker02 ~]# kubectl apply -f filebeat-config.yaml

　　三、创建filebeat的daemonset配置文件

[root@localhost ~]# cat >> filebeat.yaml <<EOF
> apiVersion: apps/v1
> kind: DaemonSet
> metadata:
>   labels:
>     app: filebeat
>   name: filebeat
>   namespace: middleware
> spec:
>   revisionHistoryLimit: 10
>   selector:
>     matchLabels:
>       app: filebeat
>   template:
>     metadata:
>       labels:
>         app: filebeat
>     spec:
>       containers:
>       - image: elastic/filebeat:5.6.14
>         imagePullPolicy: Always
>         name: filebeat
>         resources:
>           limits:
>             cpu: 200m
>             memory: 200Mi
>           requests:
>             cpu: 100m
>             memory: 100Mi
>         terminationMessagePath: /dev/termination-log
>         terminationMessagePolicy: File
>         volumeMounts:
>         - mountPath: /etc/filebeat/
>           name: config
>           readOnly: true
>         - mountPath: /var/log/containers
>           name: varlog
>         - mountPath: /var/log/pods
>           name: varlogpods
>           readOnly: true
>         - mountPath: /var/lib/docker/containers
>           name: varlibdockercontainers
>         - mountPath: /var/host/log
>           name: volume-1621230243442
>       dnsPolicy: ClusterFirst
>       imagePullSecrets:
>       - name: gaqmt
>       restartPolicy: Always
>       schedulerName: default-scheduler
>       securityContext: {}
>       terminationGracePeriodSeconds: 30
>       tolerations:
>       - effect: NoSchedule
>         key: node-role.kubernetes.io/master
>         operator: Exists
>       volumes:
>       - configMap:
>           defaultMode: 420
>           items:
>           - key: filebeat.yml
>             path: filebeat.yml
>           name: filebeat-configmap
>         name: config
>       - hostPath:
>           path: /var/log/containers
>           type: ""
>         name: varlog
>       - hostPath:
>           path: /var/log/pods
>           type: ""
>         name: varlogpods
>       - hostPath:
>           path: /var/lib/docker/containers
>           type: ""
>         name: varlibdockercontainers
>       - hostPath:
>           path: /var/log
>           type: ""
>         name: volume-1621230243442
>   updateStrategy:
>     rollingUpdate:
>       maxUnavailable: 1
>     type: RollingUpdate
> EOF

　　四、创建filebeat的pod

[root@localhost ~]# kubectl apply -f filebeat.yaml
