As a general rule, processes running without root privileges cannot bind to ports below 1024.
This PR bring support for K8S and Openshift deployment.

Very useful tool BTW, thanks.

(Some whitespace has been removed because it's automatic on my IDE (vscode), I recommend you to configure it the same way in your projects)

Oh I just saw this.

So this is something I had also started doing a while ago as well, but I stopped because I had a concern - if I push this new image, then the original command which people may have as part of automation,

docker run -p 8080:80 -p 8443:443 --rm -t mendhak/http-https-echo

will break right away. That's why I added these instructions in the readme.

What's a good way out of this?

I tried to think of ideas. I could leave the current :latest tag on Docker Hub and stop auto-building it and let it go stale, and only move to versioned tags? So this new PR becomes :15.

Any other ideas?

[Sispheor]

Sure you can start using versioning. And maintain a changelog to keep people aware of breaking changes.

Basically I don't want to break stuff for people like me who are already using :latest in scripts/automation etc - only at times like this I realize I should have versioned from the beginning... but I didn't know lots of people would start using it 😅

I will review this PR, going to do some testing etc.
