Istio 操作员安装错误：unmarshalerDecoder：未知字段“策略”

Question

在一个 kubernetes 集群上，我尝试卸载 istio 控制平面及其操作员并确保它们不存在，

1.) 我部署了 istio CNI

cat <<EOF > istio-cni.yaml
apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
spec:
  components:
    cni:
      enabled: true
  values:
    cni:
      excludeNamespaces:
       - istio-system
       - kube-system
      logLevel: info
EOF
istioctl install -f istio-cni.yaml

2.) 并安装操作符 istioctl operator init

在检查操作员 pod 日志时，我可以看到：

istioctl 版本 --remote 客户端版本：1.8.2 控制平面版本：1.8.2 数据平面版本：1.8.2（1 个代理）

kubectl 版本 --short 客户端版本：v1.18.10 服务器版本：v1.18.1

Answer 1

我的一个 iop（来自 kubectl get iop -A）有“策略”或“遥测”字段，它们是 no longer supported 。所以我需要删除它们。

1. kubectl delete iop [iopname] -n istio-system

这被卡住了，因为我的控制器已经不见了。所以我必须这样做

1. kubectl edit iop [iopname] -n istio-system
2. 从finalizer 中删除istiooperators.install.istio.io
3. 申请

在此之后，当我尝试再次安装 istio-CNI 后跟 istioctl operator init 时，我看不到任何错误日志。
