nginx keycloak spring 引导反向代理重定向循环

Question

我已将 spring 启动应用程序和 keycloak 停靠以进行授权。所以，我尝试使用 nginx 作为反向代理（nginx 没有 dockerized）。当我在没有 ssl 的情况下使用 nginx 时，它工作得很好。但是当我尝试使用 https 启用 ssl 到 http 重定向时，keycloak 在输入凭据后陷入重定向循环。我的 nginx 配置

我解决了我的问题。
在 keycloak docker compose 文件中需要在 KEYCLOAK_FRONTEND_URL 添加反向代理位置
赞KEYCLOAK_FRONTEND_URL：“https://myhost.com/auth”
