Filebeat配置部署指南

在本文中,我们将了解如何配置 Filebeat 作为 DaemonSet 在我们的 Kubernetes 集群中运行,以便将日志运送到 Elasticsearch 后端。我们使用 Filebeat 而不是 FluentD 或 FluentBit,因为它是一个非常轻量级的实用程序,并且对 Kubernetes 有一流的支持,因此这是十分适合生产的配置。

部署架构

Filebeat 将在我们的 Kubernetes 集群中作为 DaemonSet 运行。它将会:


  • 部署在一个名为 logging 的单独的命名空间内

  • Pod 将会在 Master 节点和 Worker 节点被调度

  • master 节点 pods 将转发 api-server 日志,用于审计和集群管理。

  • 客户端节点 Pods 将转发工作负载相关的日志,用于应用程序可观察性

创建 Filebeat 服务账户和 ClusterRole

部署以下 manifest 以创建 Filebeat pod 所需的权限:


apiVersion: v1kind: Namespacemetadata:  name: logging---apiVersion: v1kind: ServiceAccountmetadata:  name: filebeat  namespace: logging  labels:    k8s-app: filebeat---apiVersion: rbac.authorization.k8s.io/v1beta1kind: ClusterRolemetadata:  name: filebeat  namespace: logging  labels:    k8s-app: filebeatrules:- apiGroups: [""] # "" indicates the core API group  resources:  - namespaces  - pods  verbs:  - get  - watch  - list---apiVersion: rbac.authorization.k8s.io/v1beta1kind: ClusterRoleBindingmetadata:  name: filebeat  namespace: loggingsubjects:- kind: ServiceAccount  name: filebeat  namespace: kube-systemroleRef:  kind: ClusterRole  name: filebeat  apiGroup: rbac.authorization.k8s.io
复制代码


我们应该从安全的角度出发,确保 ClusterRole 的权限尽可能地受到限制。如果与该服务账户相关联的任何一个 pod 被泄露,那么攻击者将无法获得对整个集群或其中运行的应用程序的访问权限。

创建 Filebeat ConfigMap

使用以下 manifest 来创建一个 ConfigMap,它将由 Filebeat pod 使用:


apiVersion: v1kind: Namespacemetadata:  name: logging---apiVersion: v1kind: ConfigMapmetadata:  name: filebeat-config  namespace: logging  labels:    k8s-app: filebeat    kubernetes.io/cluster-service: "true"data:  filebeat.yml: |-    filebeat.config:    #  inputs:    #    path: ${path.config}/inputs.d/*.yml    #    reload.enabled: true      modules:        path: ${path.config}/modules.d/*.yml        reload.enabled: true
filebeat.autodiscover: providers: - type: kubernetes hints.enabled: true include_annotations: ["artifact.spinnaker.io/name","ad.datadoghq.com/tags"] include_labels: ["app.kubernetes.io/name"] labels.dedot: true annotations.dedot: true templates: - condition: equals: kubernetes.namespace: myapp #Set the namespace in which your app is running, can add multiple conditions in case of more than 1 namespace. config: - type: docker containers.ids: - "${data.kubernetes.container.id}" multiline: pattern: '^[A-Za-z ]+[0-9]{2} (?:[01]\d|2[0123]):(?:[012345]\d):(?:[012345]\d)'. #Timestamp regex for the app logs. Change it as per format. negate: true match: after - condition: equals: kubernetes.namespace: elasticsearch config: - type: docker containers.ids: - "${data.kubernetes.container.id}" multiline: pattern: '^\[[0-9]{4}-[0-9]{2}-[0-9]{2}|^[0-9]{4}-[0-9]{2}-[0-9]{2}T' negate: true match: after processors: - add_cloud_metadata: ~ - drop_fields: when: has_fields: ['kubernetes.labels.app'] fields: - 'kubernetes.labels.app'
output.elasticsearch: hosts: ['${ELASTICSEARCH_HOST:elasticsearch}:${ELASTICSEARCH_PORT:9200}']
复制代码


关于 Filebeat ConfigMap 需要了解以下几个重要概念:


  • hints.enabled: 这将激活 Filebeat 的 Kubernetes 的 hint 模块。通过使用这个,我们可以使用 pod 注释直接将 config 传递给 Filebeat pod。我们可以指定不同的多行模式和其他各种类型的配置。更多关于这方面的内容可以访问以下链接:

  • https://www.elastic.co/guide/en/beats/filebeat/current/configuration-autodiscover-hints.html

  • include_annotations: 将此设置为 “true”,可以让 Filebeat 保留特定日志条目的任何 pod 注释。这些注释可以在以后用于在 Kibana 控制台中过滤日志。

  • include_labels: 将此设置为 “true”,可以让 Filebeat 保留特定日志条目的任何 pod 标签,这些标签以后可以用于在 Kibana 控制台中过滤日志。

  • 我们还可以针对特定的命名空间过滤日志,然后可以对日志条目进行相应的处理。这里使用的是 docker 日志处理器。我们也可以针对不同的命名空间使用不同的多行模式。

  • 因为我们使用 Elasticsearch 作为存储后端,所以输出设置为 Elasticsearch。另外,这也可以指向 Redis、Logstash、Kafka 甚至是一个 File。更多信息可以查看以下链接:

  • https://www.elastic.co/guide/en/beats/filebeat/current/configuring-output.html

  • 云元数据处理器在日志条目中包含一些特定主机的字段。当我们试图过滤特定 worker 节点的日志时,这很有帮助。

部署 Filebeat DaemonSet

使用以下 manifest 来部署 Filebeat DaemonSet:


apiVersion: v1kind: Namespacemetadata:  name: logging---apiVersion: extensions/v1beta1kind: DaemonSetmetadata:  name: filebeat  namespace: logging  labels:    k8s-app: filebeatspec:  template:    metadata:      labels:        k8s-app: filebeat    spec:      serviceAccountName: filebeat      terminationGracePeriodSeconds: 30      tolerations:      - effect: NoSchedule        key: node-role.kubernetes.io/master      containers:      - name: filebeat        image: elastic/filebeat:6.5.4        args: [          "-c", "/usr/share/filebeat/filebeat.yml",          "-e",        ]        env:        - name: ELASTICSEARCH_HOST          value: elasticsearch.elasticsearch        - name: ELASTICSEARCH_PORT          value: "9200"        securityContext:          runAsUser: 0          # If using Red Hat OpenShift uncomment this:          #privileged: true        resources:          limits:            memory: 200Mi          requests:            cpu: 100m            memory: 100Mi        volumeMounts:        - name: config          mountPath: /usr/share/filebeat/filebeat.yml          readOnly: true          subPath: filebeat.yml        - name: inputs          mountPath: /usr/share/filebeat/inputs.d          readOnly: true        - name: data          mountPath: /usr/share/filebeat/data        - name: varlibdockercontainers          mountPath: /var/lib/docker/containers          readOnly: true      volumes:      - name: config        configMap:          defaultMode: 0600          name: filebeat-config      - name: varlibdockercontainers        hostPath:          path: /var/lib/docker/containers      - name: inputs        configMap:          defaultMode: 0600          name: filebeat-inputs      # data folder stores a registry of read status for all files, so we don't send everything again on a Filebeat pod restart      - name: data        hostPath:          path: /var/lib/filebeat-data          type: DirectoryOrCreate---
复制代码


让我们来看看这里发生了什么:


  • 每个 pod 的日志都被写入 /var/log/docker/containers 。我们将这个目录从主机挂载到 Filebeat pod 上,然后 Filebeat 根据提供的配置处理日志。

  • 我们将环境变量 ELASTICSEARCH_HOST 设置为 elasticsearch.elasticsearch,以引用本教程第一部分创建的 Elasticsearch 客户端服务。如果你已经有一个 Elasticsearch 集群在运行,环境变量应该设置为指向它。


请注意 manifest 中的以下设置:


...      tolerations:      - effect: NoSchedule        key: node-role.kubernetes.io/master...
复制代码


这确保了我们的 Filebeat DaemonSet 也会在 master 节点上调度一个 pod。一旦部署了 Filebeat DaemonSet,我们就可以检查我们的 pod 是否被正确调度。

如果我们跟踪其中一个 pod 的日志,我们可以清楚地看到它连接到 Elasticsearch,并且已经启动了文件的 harvester。以下代码段可以看到这一点:

复制代码


一旦我们运行了所有的 pods,那么我们就可以在 Kibana 中创建一个 filebeat-* 类型的索引模式。Filebeat 索引一般都是有时间戳的。只要我们创建了索引模式,就可以看到所有可搜索的可用字段,并导入。最后,我们可以搜索我们的应用程序日志,并在需要时创建 dashboard。强烈建议在我们的应用程序中使用 JSON logger,因为它使日志处理变得非常容易,并且可以轻松地解析消息。

总结

我们的日志堆栈方案配置到此结束。所有提供的配置文件都已经在生产环境中进行了测试,并且是可以随时部署的。欢迎实践,也十分欢迎你向我们分享关于 Kubernetes 的各种实践。
