## 1. BUILD ARGS
# These allow changing the produced image by passing different build args to adjust
# the source from which your image is built.
# Build args can be provided on the commandline when building locally with:
# podman build -f Containerfile --build-arg FEDORA_VERSION=40 -t local-image
# SOURCE_IMAGE arg can be anything from ublue upstream which matches your desired version:
# See list here: https://github.com/orgs/ublue-os/packages?repo_name=main
# - "silverblue"
# - "kinoite"
# - "sericea"
# - "onyx"
# - "lazurite"
# - "vauxite"
# - "base"
#
# "aurora", "bazzite", "bluefin" or "ucore" may also be used but have different suffixes.
ARG SOURCE_IMAGE="silverblue"
## SOURCE_SUFFIX arg should include a hyphen and the appropriate suffix name
# These examples all work for silverblue/kinoite/sericea/onyx/lazurite/vauxite/base
# - "-main"
# - "-nvidia"
# - "-asus"
# - "-asus-nvidia"
# - "-surface"
# - "-surface-nvidia"
#
# aurora, bazzite and bluefin each have unique suffixes. Please check the specific image.
# ucore has the following possible suffixes
# - stable
# - stable-nvidia
# - stable-zfs
# - stable-nvidia-zfs
# - (and the above with testing rather than stable)
ARG SOURCE_SUFFIX="-main"
## SOURCE_TAG arg must be a version built for the specific image: eg, 39, 40, gts, latest
ARG SOURCE_TAG="latest"
### 2. SOURCE IMAGE
## this is a standard Containerfile FROM using the build ARGs above to select the right upstream image
FROM ghcr.io/ublue-os/${SOURCE_IMAGE}${SOURCE_SUFFIX}:${SOURCE_TAG}
### 3. MODIFICATIONS
## make modifications desired in your image and install packages by modifying the build.sh script
## the following RUN directive does all the things required to run "build.sh" as recommended.
COPY build.sh /tmp/build.sh
RUN mkdir -p /var/lib/alternatives && \
/tmp/build.sh && \
ostree container commit
## NOTES:
# - /var/lib/alternatives is required to prevent failure with some RPM installs
# - All RUN commands must end with ostree container commit
# see: https://coreos.github.io/rpm-ostree/container/#using-ostree-container-commit

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
