默认情况下，Docker不允许与其他存储（例如GCP）一起挂载。您可以做的是在运行具有特权选项的容器时，可以将其装入存储。

Docker won't allowed to mount with other storages(like GCP) by default. What you can do is when running the container with privileged option you can mount with the storage.

将此命令放入脚本文件（gcp.sh）并构建docker映像。

Put this command in script file(gcp.sh) and build the docker image.

RUN gcsfuse --key-file /creds.json \
  --debug_gcs --debug_http --debug_fuse --debug_invariants \
  --dir-mode "777" -o allow_other spm-bucket /mnt/uploads

gcp.sh：

gcsfuse --key-file /creds.json --debug_gcs --debug_http --debug_fuse --debug_invariants --dir-mode "777" -o allow_other spm-bucket /mnt/uploads

和Dockerfile：

and the Dockerfile:

USER www-data
COPY gcp.sh /home
RUN chmod +x /home/gcp.sh
CMD cd /home && ./gcp.sh

最后，在生成映像后，使用--privileged选项$ b运行容器$ b docker run --privileged

and finally after build the image run the container with --privileged option docker run --privileged
