fails to deploy when running podman create as part of container image build

[cdrage]

Using the default bootc-image-builder command, I'm unable to create something like this in a Containerfile:

FROM quay.io/centos-bootc/fedora-bootc:eln

RUN echo "root:root" | chpasswd
RUN podman create --name hello --restart=always -p 8080:8080 cdrage/helloworld

I'm getting the error:

ostree container image deploy --imgref=ostree-unverified-image:dir:/tmp/tmpo2itqhqp/image --stateroot=default --target-imgref=ostree-remote-registry::quay.io/podai/test --karg=rw --karg=console=tty0 --karg=console=ttyS0 --karg=root=LABEL=root --sysroot=/run/osbuild/tree

Even after adding RUN ostree container commit to the Containerfile, it does not make a difference.

This issue is unrelated to b-i-b (whose job is to transform container images into disk images) - it's more an issue for https://github.com/centos/centos-bootc today (which is the operating-system-as-container base image).

[cgwalters]

The (slightly) longer answer here today is that you need to do https://centos.github.io/centos-bootc/builds/#embedding-application-containers - in theory we could perhaps try to translate build-time podman create invocations into quadlets...

[cdrage]

Ah, thank you. I for some reason expected it to be near 100% exact like a normal operating system so something like adding a RUN command to start on boot would have it boot up. Thank you for the documentation, I'll go through https://centos.github.io/centos-bootc/builds/#embedding-application-containers

[cgwalters]

Although I see why you filed it here, because we failed at deployment time and not build time which is a bit surprising...hmm

[cdrage]

Closing as this is resolved with upstream fedora bootc documentation now.
