Alpine Docker 上的 gcsfuse

我尝试使用 gcsfuse 将应用程序源代码存储在 GCP 存储桶上，这是我的 Dockerfile：

ARG VERSION

无需使用 gcsfuse 即可构建图像，但构建时使用：

gcsfuse mybucketname $APP_DIR

这是我遇到的错误：

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

有没有什么解决方法可以让它正常工作docker build？

感谢您的支持

答案1

仅在构建阶段安装 gcsfuse。将gcsfuse安装部分放在脚本中，并在 中使用脚本CMD。

然后使用以下命令运行容器--privileged

答案2

您必须/dev/fuse从命令行或从docker-compose.yml设置中公开privileged：

myproject:
  privileged: true
  devices:
    - "/dev/fuse:/dev/fuse"

我的 Dockerfile 改编自 Ernest 的 docker-gcsfuse：

FROM golang:alpine AS builder
ARG GCSFUSE_VERSION=0.27.0
RUN apk --update --no-cache add git fuse fuse-dev;
RUN go get -d github.com/googlecloudplatform/gcsfuse
RUN go install github.com/googlecloudplatform/gcsfuse/tools/build_gcsfuse
RUN build_gcsfuse ${GOPATH}/src/github.com/googlecloudplatform/gcsfuse /tmp ${GCSFUSE_VERSION}

COPY --from=builder /tmp/bin/gcsfuse /usr/bin
COPY --from=builder /tmp/sbin/mount.gcsfuse /usr/sbin
RUN ln -s /usr/sbin/mount.gcsfuse /usr/sbin/mount.fuse.gcsfuse
WORKDIR /

通过 fstab 挂载（key_file可选）：

echo "$BUCKET $MOUNTPOINT gcsfuse rw,user,noauto,key_file=$KEYFILE_PATH" >> /etc/fstab
mount.gcsfuse $BUCKET $MOUNTPOINT

答案3

当使用最新版本的 go 时，您需要使用 GO111MODULE=off 以避免错误。

FROM golang:alpine AS builder
ARG GCSFUSE_VERSION=0.27.0
ENV GO111MODULE=off
RUN apk --update --no-cache add git fuse fuse-dev;
RUN go get -d github.com/googlecloudplatform/gcsfuse
RUN go install github.com/googlecloudplatform/gcsfuse/tools/build_gcsfuse
RUN build_gcsfuse ${GOPATH}/src/github.com/googlecloudplatform/gcsfuse /tmp ${GCSFUSE_VERSION}

FROM alpine
COPY --from=builder /tmp/bin/gcsfuse /usr/bin
COPY --from=builder /tmp/sbin/mount.gcsfuse /usr/sbin
RUN ln -s /usr/sbin/mount.gcsfuse /usr/sbin/mount.fuse.gcsfuse
