Azure: Install/Configure CLI

This post will show you how to install the Azure CLI.

First you need to install the CLI.

Once it is installed you can set your config directory. This is useful for having multiple logins going at the same time.

set AZURE_CONFIG_DIR=<YOUR_DIRECTORY>

You can then login. There are different ways to do that

Way 1: This will popup a login where you enter your login credentials

az login

Way 2: This will ask you for password via the command line

az login -u <YOUR_LOGIN>

Way 3:

az login -u <YOUR_LOGIN> -p <YOUR_PASSWORD>

Way 4: logs in as a service principal

az login --service-principal --user-name <SPN_ID> --password <SPN_KEY> --tenant <TENANTID>

Show your Account

az account show

Set Account Subscription

az account set -s <SUBSCRIPTION_ID>

List Tags For A Resource

az tag list --subscription <SUBSCRIPTION_NAME>

Install Graph

az extension add --name resource-graph

Query for Anything that Has a Tag

az graph query -q "resourceGraoup, type, tags" | where tags.<TAG_NAME>=~'<VALUE>'

Query for More than One Tag

az graph query -q "resourceGraoup, type, tags" | where tags.<TAG_NAME>=~'<VALUE>' | tags.<TAG_NAME>=='<VALUE>'

Query Type

az graph query -q "resourceGroup, type, tags" | where type =~ 'microsoft.sql/servers/databases'

Databricks: Set Spark Configs

This post is how to set the spark configs on Databricks or Synapse Notebooks.

First you will need a spark session. Refer to PySpark: Create a Spark Session for more details.

secret = 'value' #I highly suggest you get the password from the keyvault
storage_account = ''
application_id = ''
tenant_id = ''
 
spark.config.set('fs.azure.account.auth.type.{}.dfs.core.windows.net'.format(storage_account), 'OAuth')
 
spark.config.set('fs.azure.account.oauth.provider.type.{}.dfs.core.windows.net'.format(storage_account), 'org.apache.hadoop.fs.azurebfs.oauth2.ClientCredsTokenProvider')
 
spark.config.set('fs.azure.account.oauth2.client.id.{}.dfs.core.windows.net'.format(storage_account), application_id)
 
spark.config.set('fs.azure.account.oauth2.client.secret.{}.dfs.core.windows.net'.format(storage_account), secret)
 
spark.config.set('fs.azure.account.oauth2.client.endpoint.{}.dfs.core.windows.net'.format(storage_account), 'https://login.microsoftonline.com/{}/oauth2/token'.format(tenant_id))

If you are running in Databricks you could add them to cluster start. Although I recommand doing it in a notebook instead.

spark.hadoop.fs.azure.account.auth.type.<STORAGE_ACCOUNT>.dfs.core.windows.net OAuth
fs.azure.account.oauth.provider.type.<STORAGE_ACCOUNT>.dfs.core.windows.net org.apache.hadoop.fs.azurebfs.oauth2.ClientCredsTokenProvider
fs.azure.account.oauth2.client.id.<STORAGE_ACCOUNT>.dfs.core.windows.net <CLIENT_ID>
fs.azure.account.oauth2.client.secret.<STORAGE_ACCOUNT>.dfs.core.windows.net secret
fs.azure.account.oauth2.client.endpoint.<STORAGE_ACCOUNT>.dfs.core.windows.net https://login.microsoftonline.com/<TENANT_ID>/oauth2/token

This will publish events to event hub. The important part here is the “EndPoint”. You need to login to Azure Portal and get the get the endpoint from the “Shared Access Policies” from the event hub namespace.

from azure.eventhub import EventHubProducerClient, EventData, EventHubConsumerClient
 
connection_str = 'Endpoint=sb://testeventhubnamespace.servicebus.windows.net/;SharedAccessKeyName=<<THE_ACCESS_KEY_NAME>>;SharedAccessKey=<<THE_ACCESS_KEY>>'
eventhub_name = '<<THE_EVENT_HUB_NAME>>'
producer = EventHubProducerClient.from_connection_string(connection_str, eventhub_name=eventhub_name)
 
event_data_batch = producer.create_batch()
 
event_data_batch.add(EventData('My Test Data'))
 
with producer:
    producer.send_batch(event_data_batch)

Create a Consumer

This will monitor the event hub for new messages.

from azure.eventhub import EventHubProducerClient, EventData, EventHubConsumerClient
 
connection_str = 'Endpoint=sb://testeventhubnamespace.servicebus.windows.net/;SharedAccessKeyName=<<THE_ACCESS_KEY_NAME>>;SharedAccessKey=<<THE_ACCESS_KEY>>'
eventhub_name = '<<THE_EVENT_HUB_NAME>>'
consumer_group = '<<THE_EVENT_HUB_CONSUMER_GROUP>>'
client = EventHubConsumerClient.from_connection_string(connection_str, consumer_group, eventhub_name=eventhub_name)
 
def on_event(partition_context, event):
    print("Received event from partition {} - {}".format(partition_context.partition_id, event))
    partition_context.update_checkpoint(event)
 
with client:
    #client.receive(
    #    on_event=on_event, 
    #    starting_position="-1",  # "-1" is from the beginning of the partition.
    #)
    client.receive(
        on_event=on_event
    )

Azure Toolkit Installation for Eclipse

In this tutorial I will show you how to install the Azure Toolkit for Eclipse. Ensure you have already installed Eclipse.

Step 1: Click Eclipse Marketplace.

Step 2: Search for “Azure Toolkit”.

Step 3: Review License.

Step 4: Click Finish. It will now install Azure Toolkit.
