报错信息 #

Error: could not get vault configuration: error reading from vault: Error making API request.

URL: GET http://vault:8200/v1/auth/kubernetes/login
Code: 400. Errors:
* missing client token

排查与解决建议 #

• 网络连通性检查：确认Argo CD的repo-server Pod能正常访问Vault服务地址http://vault:8200，可通过在repo-server Pod内执行curl命令验证
• Vault Kubernetes Auth配置验证：
  • 确认Vault已启用Kubernetes auth后端，且创建了对应认证role
  • 检查argocd-repo-server使用的ServiceAccount是否被授权绑定到Vault的认证role
  • 验证vault-configuration Secret中存储的Vault配置参数（如VAULT_ROLE、KUBERNETES_AUTH_PATH等）是否正确
• 权限与路径验证：确保Vault中secret/path/in/vault路径存在，且认证role拥有该路径的读取权限
• 插件执行环境检查：确认argocd-repo-server容器中已正确安装argocd-vault-plugin，且版本与配置兼容
