Question

我一直在尝试为树莓派3上的python项目创建基本的ci / cd管道。我正在使用Jenkins构建Docker映像并将其推送到我的Dockerhub存储库中，但是在Jenkins期间遇到错误构建：

[91mstandard_init_linux.go:211: exec user process caused "exec format error"

我的Dockerfile如下

FROM arm32v7/python:3.7-slim-buster

WORKDIR /usr/src/app

COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

COPY . .

CMD [ "python", "./main.py" ]

该问题发生在 RUN pip install 命令上，所以我认为Jenkins worker可能无法访问该文件。因此，我添加了一个额外的命令来更改权限：

FROM arm32v7/python:3.7-slim-buster

WORKDIR /usr/src/app
RUN chmod u=rwx,g=rx,o=rx requirements.txt
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

COPY . .

CMD [ "python", "./main.py" ]

Jenkins构建失败，并在 chmod 命令上出现相同的错误，并且由于所有/ bin / sh命令均失败，因此它似乎根本无法运行任何/ bin脚本。我以为是因为Jenkins无法指定某些命令，因为我在armv732中指定了构建？我目前在运行Ubuntu的计算机的本地主机上运行Jenkins。我对Jenkins和Docker都非常陌生，所以我对系统如何工作的细节不熟悉。任何帮助将不胜感激。

Answer 1

您得到的错误表明该二进制文件是针对CPU体系结构而不是您在Jenkins中用作构建从属体系结构的。 Dockerfile中的大多数命令都是根据Dockerfile中指定的映像在容器内执行的，因此架构必须匹配。

Jenkins Dockerfile构建：[91mstandard_init_linux.go：211：exec用户进程导致“ exec格式错误”
