Original GitHub issue: https://github.com/fsouza/fake-gcs-server/issues/114

I'm trying to run the server, here is my command to start the Docker container:
docker run -d --name fake-gcs-server -p 4443:4443 -v %CD%\bot\tests\data:/data fsouza/fake-gcs-server

It starts with no problems, but using both cURL and Postman gives the same response when hitting https://127.0.0.1:4443/storage/v1/b:

open /storage/: no such file or directory

I'm clearly missing something here, but can't think what...

Hey @Tohaker, thanks for opening this issue. This is weird 😞 Do you see anything in the container logs or more information in the response data?

Sorry for the delayed response x)

Here are the logs:

time="2019-11-08T18:19:27Z" level=warning msg="couldn't read file \"/data/bot-images/cropped\", skipping" error="read /data/bot-images/cropped: is a directory"
time="2019-11-08T18:19:27Z" level=info msg="couldn't load any objects or buckets from \"/data\", starting empty"
time="2019-11-08T18:19:27Z" level=info msg="server started at https://[::]:4443"

Perhaps my folder structure is too deep? I assumed it would replicate the folder structure I give it.

As suspected, I flattened the folder structure and it worked. Is there any way to make this work with nested folders? My real bucket has a directory structure that I'd like to test against.

@Tohaker gotcha, thanks for posting the logs. Yeah, currently we don't support recursively creating the objects, but we could implement it, checking for a file/directory here: github.com/fsouza/fake-gcs-server@10d4e3a3d2/main.go (L69)

I may be able to do it over the weekend depending on how cold it gets 😁

That would be much appreciated 😄 Sadly I'm not familiar with GO otherwise I'd try to submit a PR myself.

Same issue here, using Docker Desktop for MacOS. Part of the compose file:

...

blobstore:
    container_name: blobstore
    build:
      context: ./blobstore
      dockerfile: Dockerfile
    ports:
      - "4443:4443/tcp"
    volumes:
      - "/usr/local/var/blobstore:/data"

...

Running the example curls:

$ open /storage/: no such file or directory

Running docker logs:

$ time="2019-12-09T00:59:42Z" level=info msg="couldn't load any objects or buckets from \"/data\", starting empty"
$ time="2019-12-09T00:59:42Z" level=info msg="server started at https://[::]:4443"

If this is useful info:

No issues with the volume mounting; it gets created on host at the specified path.
Volume directory stays empty before and after running the failed command (maybe that's normal).
OS: MacOS Catalina, shell: zsh.

Can confirm that mapping volume /tmp:/data works. My previous volume mapping /usr/local/var/blobstore:/data

I'm having the same issue on Linux when mounting a data volume that's initially empty:

$ mkdir data
$ docker run --rm -p 4443:4443 -v ${PWD}/data:/data fsouza/fake-gcs-server  
time="2019-12-21T19:26:04Z" level=info msg="couldn't load any objects or buckets from \"/data\", starting empty"
time="2019-12-21T19:26:04Z" level=info msg="server started at https://[::]:4443"

Adding a trailing slash to the URL generates a different error:

@kaime try the technique mentioned above, don't do nested paths (unfortunately). just do /tmp/data or something more specific than data to avoid potential name conflicts in /tmp.

Alternatively, if you're using Go, checkout gocloud.dev, they provide seamless abstraction over your object storage solution, using either in-memory or local filesystem for local development.

@gerardmrk sorry, seeing this now. Will reopen the issue so it's easier to track.

Is /usr/local/var/blobstore an empty directory?
