Azure setup

Get your Azure account

Get an Azure account, if you don't already have one:

• Go to https://azure.microsoft.com/

• Sign up.

Azure offers a free trial period; this is fine for this demo. When we did a free trial period, Azure required a credit card.

Azure offers Pay-As-You-Go signup; this is what we use. If you use Pay-As-You-Go, remember to delete resources when you're done with them.

Get Azure command line software (optional)

To install Azure CLI on macOS via brew:

sh $ brew update && brew install azure-cli

To install Azure CLI via python pip:

sh $ pip install azure --upgrade --user

Verify:

sh $ az --version azure-cli (2.0.33) ...

Get your Azure subscription id

Get your Azure subscription id:

• Go to https://portal.azure.com

• To see your subscription id, look on the web page left side icon column.

• Click the item "Cost Management + Billing".

• You see "Active subscriptions you've created" and a column "SUBSCRIPTION ID" column.

• Make a note of your subscription id.

Sign in (optional)

To use the Azure CLI to sign in:

sh $ az login To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code NGYE5M41LJ18224T to authenticate.

Successful sign in will reply with JSON.

Example:
