Figure out how to build kernel as part of CI/CD and hook it to the os yaml file

As you may know, if you tried to build tinkie by yourself or if you read README.md and kernel/README.md, this is the workflow more or less.
if you need to rebuild a kernel, you can do:
$ cd kernel
$ make build_5.10.x
---> e08367d496ed
Step 33/35 : COPY --from=kernel-build /out/* /
---> 48cbcdadd35d

Tagging linuxkit/alpine@sha256:bca9e72a17c1c74cf7b28a397c643048fd055fa096a3edfe1d16365a5307b9d9 as linuxkit/alpine:e2391e0b164c57db9f6c4ae110ee84f766edc430
At that point, I usually tag the image I get, and I push it to my registry: docker.io/gianarb.
$ docker tag linuxkit/kernel:5.10.11-1ce7f0bd892ab1e3b15f1d2ae9197401eca03654-amd64 gianarb/tinkie-kernel:5.10.x
$ docker push gianarb/tinkie-kernel:5.10.x
The push refers to repository [docker.io/gianarb/tinkie-kernel]
49d9db376899: Layer already exists
5.10.x: digest: sha256:557e71bfd56932c3f4d5e22e8fec82cf92cf9b340e880f723ed8b65e47aa5d95 size: 530
Now that I have a new version of the kernel, I can build tinkie:
# from the project root
make dist
It will use the new kernel I just pushed. If the kernel tag has changed, it should change here as well:
https://github.com/gianarb/tinkie/blob/master/tinkie.yaml#L2
This project works manually, but ideally, I would like to figure out how we can make it all at once. Technically we do not need to build kernel and tinkie at the same time very often, but right now that's the case. I expect it to be a bit more independent in the near future.
I figured out I was overthinking. I am writing a GitHub Action workflow that should work 👍
The makefile inside kernel dir supports
make push_5.10.x
That should make the actual tagging and pushing. It supports ORG=docker.io/gianarb if you want to override the registry.
