Get Azure Functionapp master key

The name of this module is very self-explanaitory. It is useful when you want to automate an Azure Functionapp deployment.

Installation

Use your favorite NPM package manager:

$ yarn global add get-azfunc-masterkey

Usage

As a cli tool:

$ get-azfunc-masterkey <path-to-authfile>

Where the authfile is written in json format representing a single toplevel object with the following fields:

• clientId: a clientId of an Azure Active Directory application registration
• clientSecret: the clients secret
• tenant: the tenant ID
• functionApp: the name of your functionapp
• subscriptionId: the subscription ID
• resourceGroup: the resource group where the app resides

As a JS module:

const getMasterKey = require('get-azfunc-masterkey');

getMasterKey({
    /* JS object with same fields as the authfile for the cli version */
}, (err, masterKey) => {
    if (err) {
        console.err(err);
        process.exit(1);
    }
    console.log(masterKey);
});

Note: clientId, clientSecret and tenant fields can be obtained by running:

az ad sp create-for-rbac -n <application-registration-identifier>

That will create a new application registration and return the credentials (you must have the Azure cli 2.0 app and be logged in).
