Blob mapping utility for easy translation between azure urls and local paths

Blob mapping utility

When your code needs to access many mapped blobs as a mounted folder, the utility to make translation between blob urls and filepaths easier was made. It can be configured using the configuration json file.

Configuration file example:

{
  "blob_mounting_configurations": [
    {
      "storage_account_name": "examplestagingstrgacc",
      "storage_account_url": "https://examplestagingstrgacc.blob.core.windows.net/",
      "container_name": "heightstore-example1-raw",
      "mount_point": "/mnt/heightstore-example1-raw"
    },
    {
      "storage_account_name": "examplestagingstrgacc",
      "storage_account_url": "https://examplestagingstrgacc.blob.core.windows.net/",
      "container_name": "heightstore-example2-raw",
      "mount_point": "/mnt/heightstore-example2-raw"
    },
    {
      "storage_account_name": "examplestagingstrgacc",
      "storage_account_url": "https://examplestagingstrgacc.blob.core.windows.net/",
      "container_name": "heightstore-example3-raw",
      "mount_point": "/mnt/heightstore-example3-raw"
    },
    {
      "storage_account_name": "examplestagingstrgacc",
      "storage_account_url": "https://examplestagingstrgacc.blob.core.windows.net/",
      "container_name": "example-container-raw",
      "mount_point": "/mnt/example-container-raw"
    }
  ]
}

How to use

from blob_mapping_utility import BlobMappingUtility
json_config_file = "blob_mapping_config.json"

# read the file into a dictionary
with open(json_config_file) as json_file:
    config = json.load(json_file)["blob_mounting_configurations"]

# create the utility object
blob_mapping_utility = BlobMappingUtility(config)

filepath1 = "/mnt/example-container-raw/cool_picture.png
blob_url = blob_mapping_utility.get_url_from_mounted_filepath(mount_point) # -> https://examplestagingstrgacc.blob.core.windows.net/example-container-raw/cool_picture.png

filepath2 = get_mounted_filepath_from_url(blob_url) # -> /mnt/example-container-raw/cool_picture.png
