阿里kube-eventer mysql sink简单使用记录

阿里kube-eventer 可以将k8s event 直接插入mysql，根据github上的官方文档，设置sink如下：

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    name: kube-eventer
  name: kube-eventer
  namespace: kube-system
spec:

    spec:
      dnsPolicy: ClusterFirstWithHostNet
      serviceAccount: kube-eventer
      containers:
        - image: registry.aliyuncs.com/acs/kube-eventer-amd64:v1.2.0-484d9cd-aliyun
          name: kube-eventer
          command:
            - "/kube-eventer"
            - "--source=kubernetes:https://kubernetes.default"
            - --sink=mysql:?USER:[email protected](XXX.XXX.XX.XX:3306)/kube_eventer?charset=utf8
          env:
          # If TZ is assigned, set the TZ value as the time zone
          - name: TZ
            value: "Asia/Shanghai" 
          volumeMounts:
            - name: localtime
              mountPath: /etc/localtime
              readOnly: true
            - name: zoneinfo
              mountPath: /usr/share/zoneinfo
              readOnly: true
          resources:
            requests:
              cpu: 100m
              memory: 100Mi
            limits:
              cpu: 500m
              memory: 250Mi
      volumes:
        - name: localtime
          hostPath:
            path: /etc/localtime
        - name: zoneinfo
          hostPath:
            path: /usr/share/zoneinfo

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: kube-eventer
rules:
  - apiGroups:
      - ""
    resources:
      - configmaps
      - events
    verbs:
      - '*'
---
apiVersion: rbac.authorization.k8s.io/v1

    name: kube-eventer
    namespace: kube-system
---
apiVersion: v1

就可以启动（ps，必须保证coredns正常）。

在mysql上创建db及表，注意表名也是kube_eventer

create database kube_eventer;
use kube_eventer;


create table kube_eventer
(
    id               bigint(20)   not null auto_increment primary key comment 'event primary key',
    name             varchar(64)  not null default '' comment 'event name',
    namespace        varchar(64)  not null default '' comment 'event namespace',
    event_id         varchar(64)  not null default '' comment 'event_id',
    type             varchar(64)  not null default '' comment 'event type Warning or Normal',
    reason           varchar(64)  not null default '' comment 'event reason',
    message          text  not null  comment 'event message' ,
    kind             varchar(64)  not null default '' comment 'event kind' ,
    first_occurrence_time   varchar(64)    not null default '' comment 'event first occurrence time',
    last_occurrence_time    varchar(64)    not null default '' comment 'event last occurrence time',
    unique index event_id_index (event_id)
) ENGINE = InnoDB default CHARSET = utf8 comment ='Event info tables';

观测日志有如下类似输出：
