### 1. BUILD ARGS
|
2023-08-27 00:55:59 +00:00
|
|
|
## These enable the produced image to be different by passing different build args.
|
|
|
|
|
## They are provided on the commandline when building in a terminal, but the github
|
|
|
|
|
## workflow provides them when building in Github Actions. Changes to the workflow
|
|
|
|
|
## build.xml will override changes here.
|
|
|
|
|
|

|
|
|
## SOURCE_IMAGE arg can be anything from ublue upstream: silverblue, kinoite, sericea, vauxite, mate, lxqt, base
|
|
|
|
|
ARG SOURCE_IMAGE="silverblue"
|
|
|
|
|
## SOURCE_SUFFIX arg should be "main", nvidia users should use "nvidia"
|
|
|
|
|
ARG SOURCE_SUFFIX="main"
|
|
|
|
|
## FEDORA_VERSION arg must be a version built by ublue: 37 or 38 as of today
|
|
|
|
|
ARG FEDORA_VERSION="38"
|
|
|
|
|
## NVIDIA_VERSION should only be changed if the user needs a specific nvidia driver version
|
2023-08-26 16:13:59 +00:00
|
|
|
## if needing driver 535, this should be set to "-535". It is important to include the hyphen
|
2023-08-27 01:09:48 +00:00
|
|
|
ARG NVIDIA_VERSION=""
|

|
|
|
|
|
|
|
|
|
|
|
|
|
### 2. SOURCE IMAGE
|
|
|
|
|
## this is a standard Containerfile FROM using the build ARGs above to select the right upstream image
|
2023-08-27 01:09:48 +00:00
|
|
|
FROM ghcr.io/ublue-os/${SOURCE_IMAGE}-${SOURCE_SUFFIX}:${FEDORA_VERSION}${NVIDIA_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
