Mount via fstab and have not a secret in the config

[StefanSchoof]

I like to mount a blob with the /etc/fstab which is working good. I want to put my config now into a git repro.

Is there a way to use a environment variable for the client secret when mounting a blobfuse2 via the /etc/fstab?

Yes you can, kindly go through our README to understand more on what env variables can be exposed to Blobfuse for auth purpose. Kindly also note that while running through /etc/fstab your env variables may not get directly exposed to the binary as a new shell will spawn. Either put everything in a script and using /etc/fstab run that script or expose it through other means like .bashprofile file or something.

Thanks for the response.

With script you mean the part from https://github.com/Azure/azure-storage-fuse/wiki/Blobfuse2-Installation#persisting-mount with the mount.sh ? I have trouble to understand where that mount.sh comes from or if I should write my own what I should put into into that script.

To get into the process without a own sh file I tried the root .profile and the /etc/environment but that did not help.

Okay, figured it out.

Created a mount.sh with this

AZURE_STORAGE_SPN_CLIENT_SECRET=<secret> blobfuse2 --config-file=<path to config>/blobFuseConfig.yaml <mount path>

and added it to the fstab like https://github.com/Azure/azure-storage-fuse/wiki/Blobfuse2-Installation#persisting-mount explained.
