我正在尝试在docker build. 我已经阅读了其他线程，here，here，并理解这可能是一个特权问题。它可以通过--privileged在过程中添加标志来解决docker run，但我想在构建阶段立即安装桶。

附加到容器上，检查两者fuse是否gcsfuse都已安装。GOOGLE_APPLICATION_CREDENTIALS已设置，访问 Google API 没有问题。这是我得到的错误。

Dockerfile

RUN gcsfuse -o --implicit-dirs bucket mount-folder

要使用 gcsfuse 安装 bucker，您需要运行带有--privileged标志的 docker。现在的问题是，“在这种情况下如何构建一个没有任何错误的 docker 镜像”？场景：在 Dockerfile 中，您有以下行：

RUN chmod +x launcher.sh
USER ubuntu
RUN mkdir db
RUN gcsfuse mybucket /home/username/mypath
EXPOSE 8000
CMD ["python3.6","manage.py","runmodwsgi"]

你看

stderr:

The command '/bin/sh -c gcsfuse database_simrut /home/ubuntu/db' returned a non-zero code: 1

解决方法：删除线

RUN gcsfuse mybucket /home/username/mypath

从 Dockerfile 并创建一个启动器脚本，而不是具有以下内容：

#!/bin/bash
gcsfuse mybucket /home/username/mypath
python3.6 manage.py runmodwsgi

你的新码头应该是这样的：

RUN chown $USER:$USER $HOME
RUN chmod +x launcher.sh
USER ubuntu
RUN mkdir db
EXPOSE 8000
CMD ["./launcher.sh"]

输出：
