Map an azure storage blob container to a Linux VM. On prem, any cloud or from my favourite WSL2!.

**TL;DR - No time to read this and just want a shell script to do it all for you ? Here is a sample script

If you have a few minutes, read on.

The first requirement is to have blobfuse installed on your Linux OS.

Once it is installed, optional but recommended is to create a blobfuse temporary file for improved performance following this instruction.

Remember in Azure VM, /mnt is on ephemeral disk so you have to run this on every reboot - manually or part of system start up. In the script below, fill up your unix user and group name.

/usr/bin/bash

if ! [[ -d  /mnt/resource/blobfusetmp ]] ;
then
  sudo mkdir /mnt/resource/blobfusetmp -p
  sudo chown <unix-user>:<unix-group> /mnt/resource/blobfusetmp
fi

# Create the directory where you want the blob container to be mounted on your linux host. 

 if ! [[ -d /data/azure-blob-container ]] ; then sudo mkdir/data/azure-blob-container   ; fi

Ensure that the config file has the right blob account, container, key. There is a boat load of additional mount options.

To mount the filesystem, notice you can mount in user mode using the config file. Another option is to put the config file here either in variables or parameters

blobfuse /data/azure-blob-container --tmp-path=/mnt/resource/blobfusetmp --config-file=./fuse_connection.cfg -o attr_timeout=240 -o entry_timeout=240 -o negative_timeout=120 -o nonempty


#Alternately you could specify it all here

#export AZURE_STORAGE_ACCOUNT=sqlseries
#export AZURE_STORAGE_ACCESS_KEY=
#export AZURE_STORAGE_SAS_TOKEN=
#sudo blobfuse /data/azure-blob-container --tmp-path=/mnt/resource/blobfusetmp  --container-name=ocpdump-postgres -o attr_timeout=240 -o entry_timeout=240 -o negative_timeout=120

Finally if you need to unmount the filesystem - regular way - either of these works

umount /data/azure-blob-container
# Alternately run --> sudo  umount blobfuse

In the next step, you can mount an AWS S3 bucket or Google cloud storage to your OS.
