在镜像构建阶段使用gcsfuse

Question

我试图在docker build ...命令期间使用gcsfuse以便将工作目录挂载到GCP存储中，我已经在服务器故障中提出了这个问题，因为gcsfuse支持被重定向到它，但我找不到一种方法来使其工作，并且由于它是在云运行实例中，我认为在这里询问可能是一个好主意。

这是原始帖子：

我尝试使用gcsfuse来将应用程序源代码存储在GCP存储桶中，下面是我的Dockerfile：

ARG VERSION

FROM golang:1.12.5-alpine3.9 as gcsfuse-builder

ENV GOPATH /go

RUN apk --update add git=2.20.1-r0 fuse=2.9.8-r2 fuse-dev=2.9.8-r2 \
    && go get -u github.com/googlecloudplatform/gcsfuse

COPY . .

# The unrequired directories are also removed.

        node_modules/

EXPOSE $APP_PORT 443

CMD ["/usr/bin/supervisord", "-n", "-c", "/etc/supervisor/supervisord.conf"]

镜像可以在没有gcsfuse的情况下构建，但在构建时使用：

gcsfuse mybucketname $APP_DIR

下面是我遇到的错误：

fusermount: fuse device not found, try 'modprobe fuse' first

在构建docker的过程中，有没有办法让它正常工作呢？

感谢您的支持

Google Cloud Run目前不支持绑定挂载。

类似地，我不认为很多docker build环境会让你挂载东西。

我认为您在这里尝试使用反模式。Docker构建应该是封闭的和可重现的，在构建期间连接到GCS以下载可以更改/未版本化的文件不是一个好主意。
