目前存在一个问题，即部署 Vault Helm 图表时就绪探针失败。 Vault 正在工作，但每当我描述 Pod 时都会出现此错误。我如何让探测器使用 HTTPS 而不是 HTTP 如果有人知道如何解决这个问题我会很高兴慢慢失去理智？

在您的环境变量定义中，您有：
VAULT_ADDR: http://127.0.0.1:8200
并且您的 Vault 配置中禁用了非 TLS（启用了 TLS）：
listener "tcp" {
address = "0.0.0.0:8200"
cluster_address = "0.0.0.0:8201"
tls_cert_file = "/vault/userconfig/vault-server-tls/vault.crt"
tls_key_file = "/vault/userconfig/vault-server-tls/vault.key"
tls_client_ca_file = "/vault/userconfig/vault-server-tls/vault.ca"
}
您的 Readiness 探针正在 pod 中执行：
vault status -tls-skip-verify
所以这正在尝试连接到http://127.0.0.1:8200，您可以尝试更改环境变量以使用 HTTPS：VAULT_ADDR=https://127.0.0.1:8200
您的配置和环境变量不匹配可能会遇到另一个（不同的）问题：
K8s清单：
VAULT_API_ADDR: http://$(POD_IP):8200
保险库配置：
api_addr = "https://127.0.0.1:8200"
