GitHub user RuneRoven created a discussion: error with nginx while running on kubernetes
Hi. I was trying to install the platform in my kubernetes cluster running k3os..
I downloaded the repository and run the helm install. All pods starts up but in the UI node i get:
nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:17
2023/02/05 17:10:41 [emerg] 1#1: bind() to 0.0.0.0:80 failed (13: Permission denied)
nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)
I have changed the pod port in the helm charts to 8030 but i still get the same error.. i would like to run on another port anyway since i have other pods in the cluster. No pod is using port 80 atm but probably i will use it in the future for other stuff..
Not sure on how to fix this without compose a new docker and pull since it looks like this is inside the ui compose..

Hi @RuneRoven and welcome!
Which version are you running? Am I correct that you were trying to run the current development version from `dev`?

Yes, we could add a configmap here for the nginx configuration so that the internal ports can be freely assigned.

Looks like the core/backend service is not properly running. Can you provide these logs as well please? In the beginning of the log, there should be some info on service registration, selected hostname consul status.

Here is a preview that uses a configmap to customize nginx settings:
https://github.com/apache/streampipes/blob/1207-improve-helm-charts/installer/k8s/templates/core/ui-configmap.yaml
In the branch, the UI service starts on port 8088 and can be configured over the values file. Does this fit your needs?

that looks good if i interpret the code correct. being able to choose ports i quite essential in many cases where your run other services along side.. i got the stack up and running yesterday so i could start doing some initial testing.. I looked at the elements section and could not find any installed element and did not find any to install. do i need to run the full development or add some address for the elements? i do not wish to use the whole stack since i have limited hardware and i am most interested of the plc4x part..

Yes, I think this introduced the bug.
We were experimenting with running the UI container as a non-root user on k8s, but the UI is supposed to run on port 80, which is a privileged port and therefore causes the exception.
I reverted the change in dev so that this should work after the UI image was built (should take ~30 minutes).
We also have a branch [1] where we are currently improving the helm chart configuration which should be ready this week, if you have any feedback let us know!

Hi @RuneRoven,
thanks a lot for reportin the problem.
Have you started the `extensions-all-jvm` service? If so, you can check whether this service has been successfully registered in consul.
The consul user interface normally runs on port 8500.

Once started, the system performs the initial setup and installs available pipeline element.
Once ready and the login screen appears, the system starts with a default user: Try `admin@streampipes.apache.org` and `admin`.

I'm sorry, but I could not yet reproduce this error although I tried multiple times.
It seems something goes really wrong upon startup, but the errors seem to originate from dependencies.
Do you still get the same error? Can you give me some more hints on your configuration (OS, K8s version, setup) so that I can try to reproduce this?
Thanks!
