Chef installation on rhel8

Hi,
Can someone help me with chef installation on rhel8, I tried searching for pkg in https://community.chef.io/downloads/tools/infra-server?os=el
But there is no pkg for rhel8

That was the last free version of chef-server and it was never built for RHEL 8. If you are a customer then you can use latest server 15.x and find it in the support portal. If not then you'll have to use the cinc community version.
