## 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"
|
|
|
|
## FEDORA_VERSION arg must be a version built by ublue: eg, 39 or 40
|
|
ARG FEDORA_VERSION="39"
|
|
|
|
|
|
### 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}:${FEDORA_VERSION}
|
|
|
|
|
|
### 3. PRE-MODIFICATIONS
|
|
## This section is meant for any modifications to the image before the main modifications are made.
|
|
|
|
## this directory is needed to prevent failure with some RPM installs
|
|
RUN mkdir -p /var/lib/alternatives
|
|
|
|
|
|
### 4. MODIFICATIONS
|
|
## make modifications desired in your image and install packages here, a few examples follow
|
|
|
|
#### Install packages
|
|
|
|
# install a package from standard fedora repo or rpmfusion repo
|
|
# RPMfusion packages are available by default in ublue main images
|
|
# List of rpmfusion packages can be found here:
|
|
# https://mirrors.rpmfusion.org/mirrorlist?path=free/fedora/updates/39/x86_64/repoview/index.html&protocol=https&redirect=1
|
|
RUN rpm-ostree install screen
|
|
# example package from rpmfusion
|
|
#RUN rpm-ostree install vlc
|
|
|
|
#### Installation of static binaries
|
|
|
|
# static binaries can sometimes by added using a COPY directive like these below.
|
|
COPY --from=cgr.dev/chainguard/kubectl:latest /usr/bin/kubectl /usr/bin/kubectl
|
|
#COPY --from=docker.io/docker/compose-bin:latest /docker-compose /usr/bin/docker-compose
|
|
|
|
#### Change to System Configuration Files
|
|
|
|
# modify default timeouts on system to prevent slow reboots from services that won't stop
|
|
RUN sed -i 's/#DefaultTimeoutStopSec.*/DefaultTimeoutStopSec=15s/' /etc/systemd/user.conf && \
|
|
sed -i 's/#DefaultTimeoutStopSec.*/DefaultTimeoutStopSec=15s/' /etc/systemd/system.conf
|
|
|
|
|
|
### 5. POST-MODIFICATIONS
|
|
## these commands leave the image in a clean state after local modifications
|
|
RUN rm -rf /tmp/* /var/* && \
|
|
ostree container commit && \
|
|
mkdir -p /tmp /var/tmp && \
|
|
chmod 1777 /tmp /var/tmp
