setupclouddrive.sh

#!/bin/sh

# Usage:
# 1. Run this setup script (one-time)
# 2. When you want to mount your drive, run ~/mountclouddrive.sh
#    - Note: Because Bash on Windows tears down the environment when the last console is closed, you'll 
#      need to run mountclouddrive.sh for each new Bash session where you want to access Cloud Shell files

# Explanation:
# - Connect to Azure to get info about your Azure Cloud Shell storage account
# - Register your credentials with Windows
# - Drop a mountclouddrive.sh file in your home directory

# One-time setup steps
# Get some required values from Azure
STORAGE_NAME=$(az storage account list --query "[?starts_with(resourceGroup,'cloud-shell-storage-')] | [0].name" -o tsv)
STORAGE_RG=$(az storage account list --query "[?starts_with(resourceGroup,'cloud-shell-storage-')] | [0].resourceGroup" -o tsv)
STORAGE_KEY=$(az storage account keys list -n $STORAGE_NAME -g $STORAGE_RG --query [0].value -o tsv)
SHARE_NAME=$(az storage share list --account-name $STORAGE_NAME --account-key $STORAGE_KEY --query "[?starts_with(name, 'cs-')] | [0].name" -o tsv)

# Invoke Windows executable to save creds
cmdkey.exe /add:$STORAGE_NAME.file.core.windows.net /user:AZURE\\$STORAGE_NAME /pass:$STORAGE_KEY

# Make sure there's a place to mount the share
mkdir -p ~/clouddrive

# Create a new mount script with details specific to your Azure Cloud Shell
cat << EOF > ~/mountclouddrive.sh
#!/bin/sh
sudo mount -t drvfs '\\\\$STORAGE_NAME.file.core.windows.net\\$SHARE_NAME' ~/clouddrive
EOF

# Make sure the mount script is executable
chmod +x ~/mountclouddrive.sh
