[yocto] Guide to how to build a minimal system

[Andrew Stuart]

I want to build a minimal Nginx system that does nothing else but serve static files. Preferably with nothing else installed at all apart from network configuration via /etc/network/interfaces. Perhaps also optionally with ssh.

Ideally I would be able to provide the HTML files that make up the website via an initramfs file.

I’d like this to run on x86-64 on KVM.

I’m looking for a guide that shows me the key steps to implement something minimal like this.  Does such a guide exist?

I’ve watched several hours of Youtube videos on Yocto, I’ve read various getting started guides and spent several hours installing and building.

Quite how to configure something down to minimal still is not clear.

Can someone guide me please as to where to find such docs?

One additional specific question - I can see that there is a web servers layer, but how to only get the one webserver that I want (nginx) as opposed to getting them all?

thanks

Andrew
