This script allows to easily build a qemu release container, based on dockerfile introduced in previous commit.
It names image "qemu/$version" and automatically detects which ubuntu version should be used to build it. $ ./scripts/build_release_container.sh v3.1.0 $ podman run -it --rm qemu/v3.1.0 qemu-system-arm --version QEMU emulator version 3.1.0 (-dirty) Copyright (c) 2003-2018 Fabrice Bellard and the QEMU Project developers Signed-off-by: Pierrick Bouvier <[email protected]> --- scripts/build_release_container.sh | 63 ++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100755 scripts/build_release_container.sh diff --git a/scripts/build_release_container.sh b/scripts/build_release_container.sh new file mode 100755 index 00000000000..ae57aa21db3 --- /dev/null +++ b/scripts/build_release_container.sh @@ -0,0 +1,63 @@ +#!/usr/bin/env bash +# SPDX-License-Identifier: GPL-2.0-or-later + +set -euo pipefail + +script_dir=$(dirname $(readlink -f $0)) + +# The oldest buildable release we support is v3.1.0, as previous ones require +# additional tweaks in Dockerfile. +# For building previous releases (down to v0.12.0), +# see: [email protected] +oldest_release=v3.1.0 + +if [ $# -lt 1 ] || [ $# -gt 2 ]; then + echo "usage: version [git_repo]" + echo + echo "- version: tag or sha-1 (>= v3.1.0)" + echo "- git_repo: (optional) QEMU repository URL" + exit 1 +fi +version=$1;shift + +git_repo="https://gitlab.com/qemu-project/qemu.git"; +if [ $# -eq 1 ]; then + git_repo=$1;shift +fi + +year=$(date +%Y) +month=$(date +%m) +if git rev-parse $version >& /dev/null; then + year=$(git log -1 --format='%cd' --date='format:%Y' $version) + month=$(git log -1 --format='%cd' --date='format:%m' $version) +fi + +# Ubuntu LTS are published every (even) two years in April. +ubuntu= +if [ $((year % 2)) -eq 1 ]; then + # pick latest LTS from previous year + ubuntu=$((year - 1)) +elif [ $month -gt 6 ]; then + # LTS published this year should work + ubuntu=$year +else + # pick latest LTS from two years ago + ubuntu=$((year - 2)) +fi +if [ $ubuntu -lt 2014 ]; then + # oldest ubuntu release available with containers is 14.04 + ubuntu=2014 +fi +ubuntu=$((ubuntu - 2000)) +ubuntu_version=$ubuntu.04 + +dockerfile=$script_dir/../tests/docker/dockerfiles/release.docker +docker=$($script_dir/../tests/docker/docker.py probe) + +set -x +$docker build \ + -f $dockerfile \ + --build-arg QEMU_VERSION=$version \ + --build-arg UBUNTU_VERSION=$ubuntu_version \ + --build-arg QEMU_REPO="$git_repo" \ + -t qemu/$version -- 2.43.0
