Docker Dokku Keyclope重定向过多

我正试着和dokku一起运行Key斗篷，但我遇到了一个问题。没有TLS/SSL，KeyClope可以正常工作，但是当我使用letsencrypt创建SSL时。我收到太多重定向错误。（错误太多重定向）

我就是这么做的：

//Pulling Keycloak image
docker pull image jboss/keycloak

//Adding dokku tag
docker image tag <keycloak-id> dokku/keycloak

dokku app:create keycloak

//Creating ENV variables for keycloak (im not using any database right now)
dokku config:set keycloak KEYCLOAK_USER=admin KEYCLOAK_PASSWORD=admin PROXY_ADDRESS_FORWARDING=false

//deploy using the tag i.e dokku/keycloak
dokku tags:deploy


dokku proxy:ports-add keycloak http:80:8080

//https://github.com/dokku/dokku-letsencrypt
dokku config:set --no-restart myapp DOKKU_LETSENCRYPT_EMAIL=your@email.tld
dokku letsencrypt keycloak


dokku proxy:ports-add keycloak https:443:8443
dokku proxy:ports-remove keycloak http:8080:8080 http:8443:8443 https:443:8080

我的应用程序运行在Cloudflare之后，但我没有使用Cloudflare SSL或自动重定向到https。但是，当您将应用程序配置为使用letsencrypt插件时，该插件将自动更改为Nginx config，所有请求都将重定向到SSL。

乍看之下，似乎您做的一切都是正确的。我不确定nginx配置文件中的端口映射和IP地址，也不确定它是否正确部署

我把一个钥匙斗篷heroku样本叉到了里面，我正在使用它，所以你们可以看看。它具有从repo中的模板动态创建的nginx配置文件，因此它应该始终使用正确的IP地址
