第八章(三)基于Listcheck适配器的访问控

denier适配器访问控制比较死板。Listchecker的适配器更加灵活。

定义handler:

apiVersion: config.istio.io/v1alpha2
kind: listchecker
metadata:
  name: chaos
spec:
  overrides: ["v1","v3"]       # 列表
  blacklist: true              # 黑名单类型

定义template:   下面的模板相当于定义了输入参数

apiVersion: config.istio.io/v1alpha2
kind: listentry
metadata:
  name: version
spec:
  value: source.labels["version"]

定义Rule:

apiVersion: config.istio.io/v1alpha2
kind: rule
metadata:
  name: checkversion
spec:
  match: destination.labels["app"] == "prod-forecasting"
  actions:
  - handler: chaos.listchecker
    instances:
    - version.listentry
