If you deploy that in kubernetes the PREFECT ORION API HOST should be the ingress url Did you setup the ingress and service in front of your deployment

fabian wolfmann · Answer

yes i have a route and a load balancer service in front of my deployment

fabian wolfmann · Answer

but the HOST is defined dynamically

fabian wolfmann · Answer

it depends the cluster is deployed and the name of the container

davzucky · Answer

What do you mean the host is defined dynamically This is what kubernetes service is for To remove that problem

fabian wolfmann · Answer

exactly the host name is defined by kubernetes so when i build my image i dont have that specif name thats why im using 0 0 0 0 as the API HOST

fabian wolfmann · Answer

also when i run prefect kubernets template it create a k8s template with the command prefect orion start host 0 0 0 0

davzucky · Answer

Yes host 0 0 0 0 is to allow the IP to be exposed on kubernetes however the name you should put for the env var should be the public DNS name

fabian wolfmann · Answer

ok got it thanks

fabian wolfmann · Answer

And there is a way to define the env var with https i changed and its going to http only

davzucky · Answer

You could https termination on the ingress This is what we are doing at the moment Otherwise you could do that on the prefect Orion start by setting up manually the uvicorn Does it make sense
