Istio：当我启用 JWT RequestAuthentication 时，健康检查/sidecar 失败 过时了：更新：原始问题

如何解决Istio：当我启用 JWT RequestAuthentication 时，健康检查/sidecar 失败 过时了：更新：原始问题

过时了：

我保留这篇文章以供进一步参考，但您可以在

中检查更好的诊断（尚未解决，但已解决）

Istio: RequestAuthentication jwksUri does not resolve internal services names

更新：

在 Istio 日志中，我们看到了下一个错误。 uaa 是一个 kubernetes pod，提供 OAUTH 认证/授权。它是通过普通服务以名称 uaa 访问的。我不知道为什么 istiod 找不到 uaa 主机名。我必须使用特定的名称吗？ （记住，标准服务可以完美地找到 uaa 主机）

原始问题

在将 istio sidecar 注入标准 kubernetes pod 后，我有一个运行良好的服务。

我正在尝试添加 jwt 身份验证，为此，我正在遵循官方指南 Authorization with JWT

我的问题是

• 如果我在注入 istio 依赖项后创建 JWT 资源（RequestAuthorization 和 AuthorizationPolicy），一切（似乎）都能正常工作
• 但是，如果我创建 JWT 资源（RequestAuthorization 和 AuthorizationPolicy），然后注入 Istio，则 pod 不会启动。检查日志后，似乎 sidecar 无法工作（可能是检查健康状况？）

我的代码：

1. JWT 资源

apiVersion: "security.istio.io/v1beta1"
kind: "RequestAuthentication"
metadata:
  name: "ra-product-composite"
spec:
  selector:
    matchLabels:
      app: "product-composite"
  jwtRules:
  - issuer: "http://uaa:8090/uaa/oauth/token"
    jwksUri: "http://uaa:8090/uaa/token_keys"
---
apiVersion: security.istio.io/v1beta1
kind: AuthorizationPolicy
metadata:
  name: "ap-product-composite"
spec:
  selector:
    matchLabels:
      app: "product-composite"
  action: ALLOW
  # rules:
  # - from:
  #   - source:
  #      requestPrincipals: ["http://uaa:8090/uaa/oauth/token/faf5e647-74ab-42cc-acdb-13cc9c573d5d"]
  # b99ccf71-50ed-4714-a7fc-e85ebae4a8bb

2- 我使用目标规则如下

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: dr-product-composite
spec:
  host: product-composite
  trafficPolicy:
    tls:
      mode: ISTIO_MUTUAL

5- Istio 注入

kubectl get deployment product-composite  -o yaml | istioctl kube-inject -f - | kubectl apply -f -

注意：我在 SO 中检查了很多帖子，似乎健康检查对 sidecar 和其他配置产生了很多问题。我检查了指南 Health Checking of Istio Services 没有成功。具体来说，我试图禁用 sidecar.istio.io/rewriteAppHTTPProbers: "false"，但情况更糟（在这种情况下，既不启动 sidecar，也不启动服务。
