Hi!

Azure Policy definitions, initiatives, and assignments can each be exported as JSON with Azure CLI.

Here an example to export an Azure Policy. In the first we will list all the Azure Policies which contains the display name « virtual machine ». In the second step we will export the Azure Policy in JSON.

maxime@Azure:~$ az policy definition list --query "[?contains(displayName, 'virtual machine')]" -o table
Name                                  PolicyType    Mode     DisplayName                                                                                                                       Description
