Create Secure Route in Quart Project
Task information Details:
Create an edge route named htquart for service httpd , using the specified hostname and TLS certificate/key files.
正解：
解説：
See the solution below in Explanation.
Explanation:
Solution:
* Switch to the quart project:
oc project quart
* Create the secure route:
oc create route edge htquart \
--service=httpd \
--hostname=quart.apps.ocp4.example.com \
--cert=./req.crt \
--key=./req.key
* Verify:
oc get route htquart
oc describe route htquart
* Test resolution and access if DNS is available:
curl -k https://quart.apps.ocp4.example.com
This task checks route exposure, TLS termination, and secure ingress administration.
