Issues running in Kubernetes

[2o1o0]

Describe the bug
Running in Kubernetes is currently an issue as it tries to bind to a port bellow 1024

To Reproduce
Use https://bjw-s.github.io/helm-charts to generate a deployment as I usually do with this kind of projects
Currently using embedded db version to test the app
The app cannot start as it tries to bind it self to port 80
There are a few steps to match K8S hardnening requirements

Expected behavior
I can start the app as a generic K8S app

Additional context
Error :

Overriding address(es) 'http://*:8080'. Binding to endpoints defined via IConfiguration and/or UseKestrel() instead.
fail: Microsoft.Extensions.Hosting.Internal.Host[11]
Hosting failed to start
System.Net.Sockets.SocketException (13): Permission denied

Hi @2o1o0, thanks for the report.

I've done all of my testing exclusively in Docker rather than Kubernetes, so I haven't run across this issue.

I'll make a change to bind to a higher port.

@2o1o0 I haven't played with Kubernetes much,, but from what I know with docker you should be able to change the port. I can try to take a looksee

I've been setting the port with the docker port mapping: 5198:80. That's what I put in the example docker-compose.yml files.

But you do have a point that I shouldn't bind to port 80 on the app since some people are deploying the app outside of docker, and it will fail to bind.

Kubernetes let you do a lot of things, if not anything, but that doesnt mean you should do it. To achieve that, you'll need to start escalation privileges, which I'm for sure not granting to an app that doesnt actually require it for specific needs (network, CSI/storage).
Matching Kubernetes basic requirements ensure you have a better penetration and larger user base as people will be able to pick it up and us as-is. I have around 20 docker based OSS projects deployed on my local K8S, none of them require changes to make them work.

@michael-j-green thanks for taking a look!

Listen on any port other than a port less than 1024
