Logconfig

A namespace-level CRD, which represents a log collection task, is used to collect Pod container logs.

Example

define sink/interceptor directly

apiVersion: loggie.io/v1beta1
kind: LogConfig
metadata:
  name: tomcat
  namespace: default
spec:
  selector:
    type: pod
    labelSelector:
      app: tomcat
  pipeline:
    sources: |
      - type: file
        name: common
        paths:
          - stdout
    sink: |
      type: dev
      printEvents: false
    interceptors: |
      - type: rateLimit
        qps: 90000

reference sink/interceptor

apiVersion: loggie.io/v1beta1
kind: LogConfig
metadata:
  name: nginx
  namespace: default
spec:
  selector:
    type: pod
    labelSelector:
      app: nginx
  pipeline:
    sources: |
      - type: file
        name: mylog
        paths:
        - stdout
    sinkRef: default
    interceptorRef: default

spec.selector

Indicates the scope of the Pipeline configuration. You can choose to collect a batch of Pods logs.

type: pod

Collect Pods logs

`field`	`type`	`required`	`default`	`description`
labelSelector	map	true		Use this label to match Pods, support using to match value, such as `app:`

Example

spec: 
  selector:
    type: pod
    labelSelector:
      app: nginx

Indicates that logs of all Pods logs with label app: nginx under the namespace are collected.

Warning

When using type: pod, pipeline can only use file source. Only log collecting in this scene.

cluster

`field`	`type`	`required`	`default`	`description`
cluster	string	false	“”	Indicates the configuration of the specified delivery Loggie cluster. When deploying multiple sets of Loggie, it is used in with the global system configuration `discovery.kubernetes.cluster`

spec.pipeline

Indicates one Pipeline, and multiple Pipelines are not supported.

The difference from Pipelines in the configuration file is:

sources is actually a string. ｜ used in yaml to keep newlines.
sinkRef, which represents the referenced Sink CRD instance.
interceptorRef, which represents the referenced Interceptor CRD instance.

sources

In LogConfig, when type: pod, several parameters specifically for containerization are added into file source:

`field`	`type`	`required`	`description`
containerName	string	false	indicates the container name of the specified collection, it is recommended to fill in when the Pod contains multiple containers
excludeContainerPatterns	string array	false	excluded container names, in regular expression form
matchFields		false	add information from Pod to Fields
matchFields.labelKey	string array	false	Specify the Label Key value on the Pod. For example, the Pod contains Label: `app: demo`, and fill `labelKey: app`in here. In this case, the label `app: demo` on the Pod will be added to the file source fields, and the collected logs will be added with the label information. Suitable for pods that matched with different labels. ““ is supported to get all labels.
matchFields.annotationKey	string array	false	Similar to the above labelKey. Inject annotations of pod. ““ is supported
matchFields.env	string array	false	Similar to the above labelKey. Inject env of pod. “*” is supported

Example

apiVersion: loggie.io/v1beta1
kind: LogConfig
metadata:
  name: nginx
  namespace: default
spec:
  selector:
    type: pod
    labelSelector:
      app: nginx
  pipeline:
    sources: |
      - type: file
        name: mylog
        containerName: nginx
        matchFields:
          labelKey: ["app"]
        paths:
        - stdout

interceptors

`field`	`type`	`required`	`default`	`description`
interceptors	string	false		Indicates the interceptor of the Pipeline, which is used in a similar way to the sources above

sink

`field`	`type`	`required`	`default`	`description`
sink	string	false		Represents the sink of the Pipeline, which is used in a similar way to the sources above

If you want the sink and interceptor to be reused between different ClusterLogConfig/LogConfig, you can use the following ref method:

sinkRef

`field`	`type`	`required`	`default`	`description`
sinkRef	string	false		Represents the Sink CR referenced by this Pipeline

interceptorRef

`field`	`type`	`required`	`default`	`description`
interceptorRef	string	false		Represents the Interceptor CR referenced by this Pipeline
