In order to see the 503 Status code specified in the default-response-code
attribute on the host-element
I had to remove the welcome-content filter by omitting the
<location name="/" handler="welcome-content"/>
However even with that config I see the following sequence from a repeated
watch -n 2 curl -I http://localhost:8080/auth/
Server not started : Connection Refused...
Server Started... : HTTP/1.1 404 Not
Begin Web App Deployment (Keycloak): HTTP/1.1 503 Service Unvailable
Web App Deployed : HTTP/1.1 200 OK
My example configuration
<ajp-listener name="ajp" socket-binding="ajp"/>
<http-listener name="default" socket-binding="http"
<host name="default-host" alias="localhost"

thanks for the reply - I got a similar tip on the keycloak-user list
however if I configure the default-response-code=503
on the (single) host element of the undertow subsystem in Wildfly (10.1.0)
and restart the server then I get a
404 but never a 503 when I access paths of an web app (keycloak) that is
not fully initialized yet.
Seems that I'm seeing the same behaviour as those folks:
Is there anything else that one needs to configure to make this work?
In the meantime I played a bit with alternative approaches e.g.:
