Istio操作符安装错误: unmarshalerDecoder:未知字段“策略”

Question

在kubernetes集群中，我试图卸载istio控制平面及其操作符，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

在检查操作符结荚日志时，我可以看到：

istioctl版本--远程客户端版本: 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--短客户端版本: 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，即不再支持。所以我要删除它们。

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

不过，这是因为我的控制器已经不见了。所以我必须做

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

在此之后，当我再次安装istio时，我可以看到没有错误日志，然后是istioctl operator init。
