1实现详细步骤-DPDK中文网

下面是使用 Fluent Bit 进行日志收集，仅采集指定命名空间的 Pod 日志的详细步骤：

在 Kubernetes 集群中安装 Fluent Bit：
- 可以使用 Helm 安装 fluent-bit Chart。
- 也可以使用 YAML 文件直接创建 fluent-bit 的 Deployment 和相关资源。

创建一个 ConfigMap，配置 Fluent Bit 的输入和输出插件以及过滤规则。示例 YAML 文件如下：

apiVersion: v1
kind: ConfigMap
metadata:
 name: fluentbit-config
 namespace: <YOUR_NAMESPACE>
data:
 fluent-bit.conf: |
   [SERVICE]
     Flush        1
     Daemon       off
     Log_Level    info


   @INCLUDE input-kubernetes.conf
   @INCLUDE filter-kubernetes.conf
   @INCLUDE output-elasticsearch.conf

创建三个额外的 ConfigMap，分别用于定义 Fluent Bit 的输入、过滤器和输出插件的配置。示例文件如下：

input-kubernetes.conf： “`conf [INPUT] Name tail Tag kube.* Path /var/log/containers/*.log Parser docker,crio,json DB /var/log/flb_kube.db Mem_Buf_Limit 5MB

[FILTER]

Name                kubernetes


Match               kube.*
Kube_URL            https://kubernetes.default.svc:443/


Merge_Log           OnFirstLineKey log_processed


K8S-Logging.Parser  On


# Exclude some namespaces from being processed by the filter
# Filter out the logs from "kube-system" and "default" namespaces
K8S-Logging.Exclude On
K8S-Logging.Exclude_Namespaces kube-system,default


# Enable Kubernetes Audit Logs support, this requires a patched version
# of Fluent Bit. Check the official repository for more details.
##K8S-Audit.Parser   On

- filter-kubernetes.conf：
 ```conf
 [FILTER]
     Name                kubernetes


     Match               kube.*
     Kube_URL            https://kubernetes.default.svc:443/


     Merge_Log           OnFirstLineKey log_processed


     K8S-Logging.Parser  On


     # Exclude some namespaces from being processed by the filter
     # Filter out the logs from "kube-system" and "default" namespaces
     K8S-Logging.Exclude On
     K8S-Logging.Exclude_Namespaces kube-system,default


     # Enable Kubernetes Audit Logs support, this requires a patched version
     # of Fluent Bit. Check the official repository for more details.
     ##K8S-Audit.Parser   On

output-elasticsearch.conf： “`conf [OUTPUT] Name es Match * Host Port Index kubernetes_cluster

HTTP_User elastic (optional) HTTP_Passwd changeme (optional)

Retry_Limit False

TLS Off #(optional) “`

在你的目标命名空间中创建一个 DaemonSet，用于运行 Fluent Bit 的实例。示例 YAML 文件如下：

apiVersion: apps/v1
kind: DaemonSet
metadata:
 name: fluentbit-daemonset
 namespace: <YOUR_NAMESPACE>
spec:
 selector:
   matchLabels:
     app: fluent-bit
 template:
   metadata:
     labels:
       app: fluent-bit
   spec:
     containers:
       - name: fluent-bit
         image: fluent/fluent-bit:<VERSION>
         resources:
           limits:
             memory: 200Mi
           requests:
             cpu: 100m
             memory: 100Mi
         volumeMounts:
           - name: config-volume
             mountPath: /fluent-bit/etc/
         ports:
           - containerPort: 2020
     volumes:
       - name: config-volume
         configMap:
           name: fluentbit-config

替换示例 YAML 文件中的 <YOUR_NAMESPACE>、<ELASTICSEARCH_HOST> 和 <ELASTICSEARCH_PORT> 分别为目标命名空间名称、Elasticsearch 主机和端口。

应用以上 YAML 文件，创建 ConfigMap 和 DaemonSet：

kubectl apply -f <configmap_file.yaml>
kubectl apply -f <daemonset_file.yaml>

这样就配置了 Fluent Bit 以仅采集指定命名空间的 Pod 日志。你可以根据实际需求进行进一步的调整和定制化，例如添加认证或更改输出插件等。请确保适当测试和验证配置，以确保日志收集正常工作并满足预期要求。
