We have spring cloud dataflow services deployed in our EKS(Elastic Kubernetes Service in AWS).
The service was deployed with helm chart with default configuration more or less, the only thing we configured really is Spring Cloud Data Flow external database.
Now, a very strange thing is happening when trying to enter the UI:
- enter https://<url of scdf>/dashboard
- wait for maybe more than a min?
- browser fails to load the UI and the url is changed to http://<url of scdf>:8000/dashboard/index.html
- then removing the :8000 from address bar and trying again and it works!
We have no clue where does port 8000 is coming from?
Also, when u go to the root path https://<url of scdf> u see the different endpoints of the services, and they all show 8000 port - again, we haven't configured this port no where...
We have many other services which are exposed via k8s(registered as ingress services) and they are all working as expected
