Using CRD to Collect Logs to Kafka

Last updated: 2022-09-13 11:51:18

    TKE Serverless not only supports uploading logs to CLS, but also supports collecting logs to self-built Kafka or CKafka.

    Creating the CRD

    If you want to collect logs to Kafka, you only need to define the CRD. The template is as follows:

    apiVersion: cls.cloud.tencent.com/v1
    kind: LogConfig                          ## Default value
    metadata:
    name: test                                ## CRD resource name, unique in the cluster
    spec:
    kafkaDetail:
      brokers: xxxxxx       # A required item, broker address, generally it is domain name:port. If there are more than one address, separate them with ",".
      topic: xxxxxx         # A required item, topicID        
      messageKey:           # An optional item. You can specify the Pod field as the key to upload to the specified partition.
        valueFrom:
          fieldRef:
            fieldPath: metadata.name   
            timestampKey:            # The key of timestamp. Default value is @timestamp.
      timestampFormat:       # The format of timestamp. Default value is double.
    inputDetail:
      type: container_stdout                  ## Log collection type, including container_stdout (container standard output) and container_file (container file).
       containerStdout:                        ## Container standard output
        namespace: default                    ## The Kubernetes namespace of the container to be collected. If this parameter is not specified, it indicates all namespaces.
        allContainers: false                  ## Whether to collect the standard output of all containers in the specified namespace
        container: xxx                        ## Name of the container to be collected. This item can be left empty.
        includeLabels:                         ## Only Pods that contain the specified labels will be collected.
          k8s-app: xxx                        ## Only the logs generated by Pods with the configuration of "k8s-app=xxx" in the Pod labels will be collected. This parameter cannot be specified at the same time as workloads and allContainers=true.
        workloads:                            ## Kubernetes workload to which the container Pod to be collected belongs
        - namespace: prod                     ## Workload namespace
          name: sample-app                    ## Workload name
          kind: deployment                    ## Workload type. Supported values include deployment, daemonset, statefulset, job, and cronjob.
          container: xxx                      ## Name of the container to be collected. If this item is left empty, it indicates all containers in the workload Pod will be collected.
       containerFile:                          ## File in the container
        namespace: default                    ## The Kubernetes namespace of the container to be collected. A namespace must be specified.
        container: xxx                        ## Name of the container to be collected. You can enter a * for this item.
        includeLabels:                         ## Only Pods that contain the specified labels will be collected.
          k8s-app: xxx                        ## Only the logs generated by Pods with the configuration of "k8s-app=xxx" in the Pod labels are collected. This parameter cannot be specified at the same time as workload.
        workload:                             ## Kubernetes workload to which the container Pod to be collected belongs
          name: sample-app                    ## Workload name                  
          kind: deployment                    ## Workload type. Supported values include deployment, daemonset, statefulset, job, and cronjob.
        logPath: /opt/logs                    ## Log folder. Wildcards are not supported.
        filePattern: app_*.log                ## Log file name. It supports the wildcards "*" and "?". "*" matches multiple random characters, and "?" matches a single random character.
    
    

    Note

    If you are unable to collect logs, please terminate and recreate the Pod and try it again.
