You can use one or multiple blobs on Azure Storage to access data directly on your machine learning experiments and jobs.

Create an Azure Storage account

You should create a storage account (e.g. plx-storage) and a blob (e.g. data).

You need to expose information about how to connect to the blob storage, the standard way is to expose these keys:

  • AZURE_ACCOUNT_NAME
  • AZURE_ACCOUNT_KEY
  • AZURE_CONNECTION_STRING

Create a secret or a config map for storing these keys

We recommend using a secret to store your access information json object:

kubectl create secret -n polyaxon generic az-secret --from-literal=AZURE_ACCOUNT_NAME=account --from-literal=AZURE_ACCOUNT_KEY=hash-key

Use the secret to add a connection

connections:
- name: azure-dataset1
  kind: wasb
  schema:
    bucket: "wasbs://[email protected]/"
  secret:
    name: "az-secret"

If you want ot access multiple datasets using the same secret:

persistence:
- name: azure-dataset1
  kind: wasb
  schema:
    bucket: "wasbs://[email protected]/"
  secret:
    name: "az-secret"
- name: azure-dataset2
  kind: wasb
  schema:
    bucket: "wasbs://[email protected]/"
  secret:
    name: "az-secret"

Update/Install Polyaxon CE or Polyaxon Agent deployment

You can deploy/upgrade your Polyaxon CE or Polyaxon Agent deployment with access to data on Azure.

Access to the dataset in your experiments/jobs

To expose the connection secret to one of the containers in your jobs or services:

run:
  kind: job
  connections: [azure-dataset1]

Or

run:
  kind: job
  connections: [azure-dataset1, s3-dataset1]

Use the initializer to load the dataset

To use the artifacts initializer to load the dataset

run:
  kind: job
  init:
   - artifacts: [dirs: [...], files: [...]]
     connection: "azure-dataset1"

Use Polyaxon to access the dataset

This is optional, you can use any language or logic to interacts with Azure Storage.

Polyaxon has some built-in logic that you can leverage if you want.

To use that logic: 

pip install polyaxon[azure]

All possible functions to use:

from polyaxon.connections.azure.azure_blobstore import AzureBlobStoreService

store = AzureBlobStoreService(...)

store.delete()
store.ls()
store.upload_file()
store.upload_dir()
store.download_file()
store.download_dir()
