我正在使用本地 k8s v1.19 和带有 1.8.0 的 Istio。当我将 istio 网格注入到hub-dev
我们的微服务运行的位置时,我被困在正确地一起运行它们。Vault 正在运行dev
命名空间。
我遇到的第一个问题是 Vault 和 Istio sidecar 无法以某种方式正常运行,应用程序无法按如下方式初始化。我尝试使用下面的注释来初始化第一个保管库,但它没有解决下面的问题。
- vault.hashicorp.com/agent-init-first:真
- vault.hashicorp.com/agent-inject:真
这是 pod status 的输出并描述

当我尝试下面的注释时,它解决了上述问题,但是这次当 pod 开始运行时,它无法找到/vault/secrets
路径,但不知何故,当我检查代理和应用程序的日志时,它可以被读取,并且/vault/secrets
文件夹存在于 pod 中.
- vault.hashicorp.com/agent-pre-populate: "false"
即使文件夹存在,这里也是应用程序的日志

在这里,我有一些可能与保险柜本身有关的 PUT 错误,但我很困惑保险柜如何注入机密。

最后,当我检查 istio-proxy 日志时,我可以看到 GET 或 PUT 请求返回 200。
