-It is possible to pull images from private image hubs during deployment for an application. This means that you can add a reference to a private image hub in radixconfig.yaml file using the `image:` tag. See example above. A `password` for these must be set via the Radix Web Console (under Configuration -> Private image hubs).

 To get more information on how to connect to a private Azure container registry (ACR), see the following [guide](https://thorsten-hans.com/how-to-use-private-azure-container-registry-with-kubernetes). The chapter `Provisioning an Azure Container Registry` provide information on how to get service principle `username` and `password`. It is also possible to create a Service Principle in Azure AD, and then manually grant it access to your ACR.
