Containerfile

# This is the Containerfile for your custom image. 

# It takes in the recipe, version, and base image as arguments,
# all of which are provided by build.yml when doing builds
# in the cloud. The ARGs have default values, but changing those
# does nothing if the image is built in the cloud.

ARG FEDORA_MAJOR_VERSION=38
# Warning: changing this might not do anything for you. Read comment above.
ARG BASE_IMAGE_URL=ghcr.io/ublue-os/silverblue-main

FROM ${BASE_IMAGE_URL}:${FEDORA_MAJOR_VERSION}

# The default recipe set to the recipe's default filename
# so that `podman build` should just work for many people.
ARG RECIPE=./recipe.yml

# The default image registry to write to policy.json and cosign.yaml
ARG IMAGE_REGISTRY=ghcr.io/ublue-os

# Copy static configurations and component files.
# Warning: If you want to place anything in "/etc" of the final image, you MUST
# place them in "./usr/etc" in your repo, so that they're written to "/usr/etc"
# on the final system. That is the proper directory for "system" configuration
# templates on immutable Fedora distros, whereas the normal "/etc" is ONLY meant
# for manual overrides and editing by the machine's admin AFTER installation!
# See issue #28 (https://github.com/ublue-os/startingpoint/issues/28).
