Is it possible to run fake-gcs-server without root privileges?

[ViliusS]

I tried to run fake-gcs-server docker image with Kubernetes options below, but as soon the container starts it says that it is unable to mkdir /storage/

Is it possible to run the image without root privileges?

      securityContext:
        runAsNonRoot: true
        runAsUser: 65534
        fsGroup: 65534

Yes, you can use a different folder as the root for storage, or you can use a different backend, or you can custom build your Docker image.

Please review the output of ./fake-gcs-server -h for an idea of what options are available.

Ah, I was confused by different options. Looks like there are -data and -filesystem-root. I have assumed that -data (which is automatically set to /data) automatically enabled GCS server to store everything under that folder, however it seems that both need to be set. It now works as expected.
Any reason these two parameters exist as a separate options?

-data is where files are imported from, in a folder/file structure. The format of -filesystem-root is internal to fake-gcs-server and may not reflect a regular directory/file structure.

I suggest to rename -data to something like -importdata or -firstimport. It is very confusing, especially when it points to /data folder, which is usually used to actually store the data by other container providers. Redis docker image is one such example.

By the way, is it OK if both -data and -filesystem-root points to the same folder? My /data volume is persistent, won't it go into loop importing the same data on every startup?
