### 1. BUILD ARGS
## IMAGE_NAME arg can be anything from ublue upstream: silverblue, kinoite, sericea, vauxite, mate, lxqt, base
ARG IMAGE_NAME="silverblue"
## IMAGE_SUFFIX arg should be "main", nvidia users should use "nvidia"
ARG IMAGE_SUFFIX="main"
## FEDORA_MAJOR_VERSION arg must be a version built by ublue: 37 or 38 as of today
ARG FEDORA_MAJOR_VERSION="38"
## NVIDIA_MAJOR_VERSION should only be changed if the user needs a specific nvidia driver version
## if needing driver 535, this should be set to "-535". It is important to include the hyphen
ARG NVIDIA_MAJOR_VERSION=""
### 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/${IMAGE_NAME}-${IMAGE_SUFFIX}:${FEDORA_MAJOR_VERSION}${NVIDIA_MAJOR_VERSION}
### 3. PRE-MODIFICATIONS
## 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 a package from standard fedora repo
RUN rpm-ostree install screen
# install a package from rpmfusion repo
RUN rpm-ostree install vlc
# 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
# 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
