[英]GitLab CI - Trying to use docker buildx to build for ARM64
Trying to use docker buildx
with GitLabs shared runners to build a Docker image that can be run on my Raspberry Pi.尝试使用
docker buildx
和 GitLabs 共享运行器来构建可以在我的 Raspberry Pi 上运行的 Docker 映像。 Job fails saying git is not in PATH but git is installed in image: docker:stable-git
.作业失败,说 git 不在 PATH 中,但 git 安装在
image: docker:stable-git
。 Any known fixes or a better way to build an ARM64-compatible image without having to build on the Raspberry Pi itself?是否有任何已知的修复程序或更好的方法来构建与 ARM64 兼容的映像,而无需在 Raspberry Pi 本身上构建? (RPi becomes unusable while building on it due to CPU usage)
(由于 CPU 使用率,RPi 在构建时变得不可用)
deploy:
image: docker:stable-git
stage: deploy
services:
- docker:dind
before_script:
- export DOCKER_BUILDKIT=1
- export DOCKER_CLI_EXPERIMENTAL=enabled
- docker build --platform=local -o . git://github.com/docker/buildx
- mv buildx ~/.docker/cli-plugins/docker-buildx
script:
- docker buildx build --platform linux/amd64,linux/arm64 -t $CI_REGISTRY_IMAGE .
- docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
- docker push $CI_REGISTRY_IMAGE
$ export DOCKER_BUILDKIT=1
$ export DOCKER_CLI_EXPERIMENTAL=enabled
$ docker build --platform=local -o . git://github.com/docker/buildx
#1 [internal] load git source git://github.com/docker/buildx
#1 ERROR: failed to init repo at /var/lib/docker/overlay2/xxx/diff: exec: "git": executable file not found in $PATH

It looks like the issue was that the build was failing due to git not being installed in docker:dind
看起来问题是由于 git 未安装在
docker:dind
中而导致构建失败
Was able to work around the issue by cloning Docker/BuildX in a separate stage, running docker build
on it, then exporting it to the deploy stage using artifacts.能够通过在单独的阶段克隆Docker/BuildX 、在其上运行
docker build
,然后使用工件将其导出到部署阶段来解决该问题。
buildx:
image: docker:19.03-git
stage: buildx
variables:
GIT_STRATEGY: none
artifacts:
paths:
- buildx
expire_in: 1 hour
services:
- docker:19.03-dind
script:
- export DOCKER_BUILDKIT=1
- git clone git://github.com/docker/buildx ./docker-buildx
- docker build --platform=local -o . ./docker-buildx
deploy:
image: docker:19.03
stage: deploy
services:
- name: docker:19.03-dind
command: ["--experimental"]
before_script:
- mkdir -p ~/.docker/cli-plugins
- mv buildx ~/.docker/cli-plugins/docker-buildx
- docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
script:
- docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
- docker buildx create --use --name mybuilder
- docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 --push -t $CI_REGISTRY_IMAGE .
I've decided to update my answer with info about using BuildX in CircleCI due to changes made by GitLab to free accounts as well as comments posted by j0nl1 and Yajo由于 GitLab 对免费帐户所做的更改以及j0nl1和Yajo发布的评论,我决定使用有关在 CircleCI 中使用 BuildX 的信息来更新我的答案
You can download the BuildX binary and use it in your CircleCI job by doing the following您可以通过执行以下操作下载 BuildX 二进制文件并在您的 CircleCI 作业中使用它
jobs:
build-and-push:
executor: docker/machine
steps:
- checkout
- run:
name: Remove old installation
command: |
sudo systemctl stop docker.service
sudo apt remove docker-ce docker-ce-cli containerd.io
- docker/install-docker:
install-dir: /usr/bin
- run:
name: Restart docker daemon with experimental features
command: |
sudo bash -c 'echo "{\"experimental\":true}" > /etc/docker/daemon.json'
if [[ $EUID == 0 ]]; then export SUDO=""; else export SUDO="sudo"; fi
$SUDO systemctl unmask docker.service
$SUDO systemctl unmask docker.socket
$SUDO systemctl start docker.service
- run:
name: Install buildx
command: |
BUILDX_VERSION="v0.4.1"
curl -sSLo docker-buildx "https://github.com/docker/buildx/releases/download/$BUILDX_VERSION/buildx-$BUILDX_VERSION.linux-amd64"
chmod a+x docker-buildx
mkdir -p ~/.docker/cli-plugins
mv docker-buildx ~/.docker/cli-plugins/docker-buildx
docker version
docker buildx install
- docker/check:
registry: $DOCKER_REGISTRY
- run:
name: Create buildx profile
command: |
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
docker buildx create --use --name mybuilder
- docker/build:
registry: $DOCKER_REGISTRY
image: username/repo
tag: latest
extra_build_args: --platform linux/amd64,linux/arm64,linux/arm/v7 --push
