We have an http livenessProbe setup
livenessProbe:
httpGet:
path: /admin
port: http
initialDelaySeconds: 180
periodSeconds: 20but why in the description the connection is via https
Liveness probe failed: Get https://10.11.1.7:80/admin: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)Kubernetes is doing exactly what you are asking, probing the http url but your application pod web server is redirecting it to https, that is causing the error.
You can either fix that in pod or use TCP probe
