用於 Istio Mixer I/O 超時的應用程序身份和訪問適配器

Question

按照https://github.com/ibm-cloud-security/app-identity-and-access-adapter 上的安裝文檔進行操作。 一切似乎都安裝正確（盡管我確實必須更新 oidc-config.yaml 和 policy.yaml 模板文件以防止 discoveryUrl 模式出錯。

我正在使用示例文件夾中的 OIDC 示例策略，使用我的 URL 和客戶端機密進行更新。

在 Mixer 中，我收到以下錯誤：

2020-01-11T16:26:43.920036Z info    grpc: addrConn.createTransport failed to connect to {svc-appidentityandaccessadapter:47304 0  <nil>}. Err :connection error: desc = "transport: Error while dialing dial tcp 10.43.152.188:47304: i/o timeout". Reconnecting...

看起來它處於 READY 狀態，但是當我在 Web 瀏覽器中加載應用程序時，沒有任何反應，我可以直接訪問該應用程序。

通過運行檢查disablePolicyCheck

kubectl -n istio-system get cm istio -o jsonpath="{@.data.mesh}" | grep disablePolicyChecks

如果它返回disablePolicyCheck: true ，請運行以下命令：

istioctl manifest apply --set values.global.disablePolicyChecks=false \
 --set values.mixer.policy.enabled=true \
 --set values.pilot.policy.enabled=true

Istio 目前不尊重global.disablePolicyCheck配置，而沒有設置pilot.policy.enabled=true 。

此外，在Istio默認的配置文件集mixer.policy.enabled以false的性能的原因。

運行上述命令后， kubectl命令將返回disablePolicyChecks: false
