Question

我正在尝试在docker build期间在我的容器中安装存储卡扣。我已经阅读了其他主题here，here，并了解这可能是一个特权问题。可以通过在--privileged进程中添加docker run标志来解决这个问题，但我希望将垃圾桶安装在建筑阶段之外。

连接到容器，检查是否已安装fuse和gcsfuse。设置GOOGLE_APPLICATION_CREDENTIALS，访问Google API没问题。这是我得到的错误。

stderr:

Dockerfile

FROM gcr.io/google-appengine/python

.
ENV GCSFUSE_REPO=gcsfuse-jessie
RUN apt-get update && apt-get install -y ca-certificates \
    && echo "deb http://packages.cloud.google.com/apt $GCSFUSE_REPO main" > /etc/apt/sources.list.d/gcsfuse.list \
    && curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add - \
    && apt-get update && apt-get install -y gcsfuse

# Config fuse
RUN chmod a+r /etc/fuse.conf
RUN perl -i -pe 's/#user_allow_other/user_allow_other/g' /etc/fuse.conf

# Alter permission
RUN chmod a+w mount-folder

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

要使用gcsfuse安装bucker，您需要使用--privileged标志运行docker。现在的问题是，“在这种情况下如何构建没有任何错误的Docker映像”？场景：在Dockerfile中，您需要执行以下操作：

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

你看到

daemonize.Run: readFromProcess: sub-process: mountWithArgs: mountWithConn: Mount: mount: running fusermount: exit status 1

stderr:

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

解决方案：删除行

RUN gcsfuse mybucket /home/username/mypath

从Dockerfile中创建一个启动器脚本，该脚本具有以下内容：

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

您的新docker应该如下所示：

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

输出：

构建docker容器时gcsfuse无法挂载
