Add rules to allow access to login.microsoftonline.com

[stan-spotts]

Without these rules the action/login will fail, so your workflows will not be able to do much. If you're working with containers, this also affects docker/login-action.

Why:

Adding the three rules allows access to login.microsoftonline.com, which is necessary for the action azure/login@v2 to work. Otherwise its blocked. This also fixes the same problem for docker/login-action.

FWIW, the following is also useful and might possibly be added somewhere in the documentation, along with some instructions to add additional rules to support access to specific external resources. AllowDockerRegistryAndNpmOutbound is necessary to allow the job to reach registry-1.docker.io and production.cloudflare.docker.com to pull docker images, and registry.npmjs.org for npm install.

 {
        name: 'AllowDockerRegistryAndNpmOutbound'
        properties: {
          protocol: 'TCP'
          sourcePortRange: '*'
          destinationPortRange: '443'
          destinationAddressPrefix: '*'
          access: 'Allow'
          priority: 130
          direction: 'Outbound'
          destinationAddressPrefixes: [
            '54.227.20.253'
            '104.16.101.215'
            '104.16.29.34'
          ]
        }
      }

Closes:

Azure/login#439

What's being changed (if available, include any code snippets, screenshots, or gifs):

Added the following rules to the bicep file definition:

      {
        name: 'AllowAzureCloudOutbound'
        properties: {
          protocol: 'TCP'
          sourcePortRange: '*'
          destinationPortRange: '443'
          destinationAddressPrefix: 'AzureCloud'
          access: 'Allow'
          priority: 100
          direction: 'Outbound'
          destinationAddressPrefixes: []
        }
      }
      {
        name: 'AllowAzureADOutbound'
        properties: {
          protocol: 'TCP'
          sourcePortRange: '*'
          destinationPortRange: '443'
          destinationAddressPrefix: 'AzureActiveDirectory'
          access: 'Allow'
          priority: 110
          direction: 'Outbound'
          destinationAddressPrefixes: []
        }
      }
      {
        name: 'AllowAzureFrontDoorOutbound'
        properties: {
          protocol: 'TCP'
          sourcePortRange: '*'
          destinationPortRange: '443'
          destinationAddressPrefix: 'AzureFrontDoor.Frontend'
          access: 'Allow'
          priority: 120
          direction: 'Outbound'
          destinationAddressPrefixes: []
        }
      }
