## 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="40"

ARG FEDORA_VERSION=40

### 2. Build ZFS module
## Adated from https://github.com/coreos/layering-examples/blob/main/build-zfs-module/Containerfile
FROM ghcr.io/ublue-os/${SOURCE_IMAGE}${SOURCE_SUFFIX}:${SOURCE_TAG} as kernel-query
RUN rpm -qa kernel --queryformat '%{VERSION}-%{RELEASE}.%{ARCH}' > /kernel-version.txt

# Using https://openzfs.github.io/openzfs-docs/Developer%20Resources/Custom%20Packages.html
FROM registry.fedoraproject.org/fedora:${FEDORA_VERSION} as builder
COPY --from=kernel-query /kernel-version.txt /kernel-version.txt
WORKDIR /etc/yum.repos.d
RUN curl -L -O https://src.fedoraproject.org/rpms/fedora-repos/raw/f${FEDORA_VERSION}/f/fedora-updates-archive.repo && \
    sed -i 's/enabled=AUTO_VALUE/enabled=true/' fedora-updates-archive.repo
RUN dnf install -y jq dkms gcc make autoconf automake libtool rpm-build libtirpc-devel libblkid-devel \

WORKDIR /
# Uses project_id from: https://release-monitoring.org/project/11706/
RUN curl "https://release-monitoring.org/api/v2/versions/?project_id=11706" | jq --raw-output '.stable_versions[0]' >> /zfs_version.txt
RUN curl -L -O https://github.com/openzfs/zfs/releases/download/zfs-$(cat /zfs_version.txt)/zfs-$(cat /zfs_version.txt).tar.gz && \
    tar xzf zfs-$(cat /zfs_version.txt).tar.gz && mv zfs-$(cat /zfs_version.txt) zfs
WORKDIR /zfs
RUN ./configure -with-linux=/usr/src/kernels/$(cat /kernel-version.txt)/ -with-linux-obj=/usr/src/kernels/$(cat /kernel-version.txt)/ \
    && make -j1 rpm-utils rpm-kmod


### 3. 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}

### 4 Add ZFS RPMS and matching kernel RPMs
#COPY --from=ghcr.io/0ranki/sb-zfs-kernel /rpms/ /tmp/rpms
COPY --from=builder /zfs/*.rpm /zfs/

### 5. 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
