# This is an example showing how to extend the freebsd-runtime OCI image by
# installing additional packages while keeping the resulting image as small as
# possible.

# The OS version matching the desired freebsd-runtime image
ARG version=14.snap

# Select freebsd-runtime as our starting point.
FROM localhost/freebsd-runtime:${version}

# A list of package(s) to install
ARG packages

# Install package management tools. We specify 'FreeBSD' as the repository to
# use for downloading pkg since the freebsd-runtime image has both FreeBSD and
# FreeBSD-base pkg repo configs installed and FreeBSD-base does not contain the
# pkg package.
RUN env ASSUME_ALWAYS_YES=yes pkg bootstrap -r FreeBSD && pkg update

# Install some package(s).
RUN pkg install -y ${packages}

# Clean up and remove package management overhead. We delete downloaded
# packages, uninstall pkg and delete the repository metadata downloaded by 'pkg
# install'.  This retains the record of which packages are installed in the
# image.
RUN pkg clean -ay && pkg delete -fy pkg && rm -rf /var/db/pkg/repos
