DTL Artifact

Type: azure-dtlartifact

The Azure DevTest Labs provisioner can be used to apply an artifact to a VM - See Add an artifact to a VM

Configuration Reference

There are many configuration options available for the builder. We'll start with authentication parameters, then go over the Azure ARM builder specific options. In addition to the options listed here, a communicator can be configured for this builder.

Authentication options

Config allows for various ways to authenticate Azure clients. When client_id and subscription_id are specified in addition to one and only one of the following: client_secret, client_jwt, client_cert_path -- Packer will use the specified Azure Active Directory (AAD) Service Principal (SP). If only use_interactive_auth is specified, Packer will try to interactively log on the current user (tokens will be cached). If none of these options are specified, Packer will attempt to use the Managed Identity and subscription of the VM that Packer is running on. This will only work if Packer is running on an Azure VM with either a System Assigned Managed Identity or User Assigned Managed Identity.

Managed Identity

If you're running Packer on an Azure VM with a managed identity you don't need to specify any additional configuration options. As Packer will attempt to use the Managed Identity and subscription of the VM that Packer is running on.

Interactive User Authentication

To use interactive user authentication, you should specify subscription_id only. Packer will use cached credentials or redirect you to a website to log in.

Service Principal

To use a service principal you should specify subscription_id, client_id and one of client_secret, client_cert_path or client_jwt.

• subscription_id (string) - Subscription under which the build will be performed. The service principal specified in client_id must have full access to this subscription, unless build_resource_group_name option is specified in which case it needs to have owner access to the existing resource group specified in build_resource_group_name parameter.

• client_id (string) - The Active Directory service principal associated with your builder.

• client_secret (string) - The password or secret for your service principal.

• client_cert_path (string) - The location of a PEM file containing a certificate and private key for service principal.

• client_cert_token_timeout (duration string | ex: "1h30m12s") - How long to set the expire time on the token created when using client_cert_path.

• client_jwt (string) - The bearer JWT assertion signed using a certificate associated with your service principal principal. See Azure Active Directory docs for more information.

Azure DevTest Labs provisioner specific options

Required:

• dtl_artifacts ([]DtlArtifact) - Dtl Artifacts

• lab_name (string) - Name of the existing lab where the virtual machine exist.

• lab_resource_group_name (string) - Name of the resource group where the lab exist.

• vm_name (string) - Name of the virtual machine within the DevTest lab.

Optional:

• polling_duration_timeout (duration string | ex: "1h5m2s") - The default PollingDuration for azure is 15mins, this property will override that value. See Azure DefaultPollingDuration If your Packer build is failing on the ARM deployment step with the error Original Error: context deadline exceeded, then you probably need to increase this timeout from its default of "15m" (valid time units include s for seconds, m for minutes, and h for hours.)

• azure_tags (map[string]*string) - Azure Tags

DtlArtifact

• artifact_name (string) - Artifact Name

• artifact_id (string) - Artifact Id

• parameters ([]ArtifactParameter) - Parameters

ArtifactParmater

• name (string) - Name

• value (string) - Value

• type (string) - Type
