命名空间上启用了自动注入，我正在尝试使用Auto mTLS. 已验证 Istio Pilot 和 Citadel 运行正常。证书机密已正确创建和安装。istio 代理启动失败，出现以下日志。具体错误是Invalid path: ./var/run/secrets/istio/root-cert.pem

查看 istio 注入器配置映射并与另一个比较时，缺少一个 if 条件。有谁知道如何恢复这种情况？

导致错误的原因有很多。最好检查证书是否真的存在以及它是否有效。

根据 istio文档，您可以验证密钥和证书：

验证密钥和证书安装

Istio 会自动在所有 sidecar 容器中安装必要的密钥和证书以进行双向 TLS 身份验证。运行以下命令以确认密钥和证书文件存在于 /etc/certs：

$ kubectl exec $(kubectl get pod -l app=httpbin -o jsonpath={.items..metadata.name}) -c istio-proxy -- ls /etc/certs

cert-chain.pem key.pem root-cert.pem

cert-chain.pem 是 Envoy 的证书，需要出示给对方。 key.pem 是 Envoy 的私钥与 Envoy 的证书配对在 cert-chain.pem. root-cert.pem 是验证对等方证书的根证书。在这个例子中，我们在一个集群中只有一个 Citadel，所以所有的 Envoy 都有相同的 root-cert.pem.

使用该 openssl 工具检查证书是否有效（当前时间应介于 Not Before 和 之间Not After）

$ kubectl exec $(kubectl get pod -l app=httpbin -o jsonpath={.items..metadata.name}) -c istio-proxy -- cat /etc/certs/cert-chain.pem | openssl x509 -text -noout | grep Validity -A 2

Validity Not Before: May 17 23:02:11 2018 GMT Not After : Aug 15 23:02:11 2018 GMT

您还可以检查客户端证书的 身份 ：

$ kubectl exec $(kubectl get pod -l app=httpbin -o jsonpath={.items..metadata.name}) -c istio-proxy -- cat /etc/certs/cert-chain.pem | openssl x509 -text -noout | grep 'Subject Alternative Name' -A 1

X509v3 Subject Alternative Name: URI:spiffe://cluster.local/ns/default/sa/default

请查看 Istio 身份以获取有关 Istio 中服务身份 的更多信息 。

希望能帮助到你。
