How to disable https needed while running from docker ubuntu

I am using the guide and running the command

docker run -p 8080:8080 -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin

I can’t access the admin panel since i get permission denied HTTPS REQUIRED.

On ubuntu 16.04 server.and the installation was done using docker . This is a test server so i don’t want to install SSL. How can i disable it ?
