Import: tfrun

The tfrun import provides access to data associated with a Terraform run.

Note: HCP Terraform Free Edition includes one policy set of up to five policies. In HCP Terraform Plus Edition, you can connect a policy set to a version control repository or create policy set versions via the API. Refer to HCP Terraform pricing for details.

This import currently consists of run attributes, as well as namespaces for the organization, workspace and cost-estimate. Each namespace provides static data regarding the HCP Terraform application that can then be consumed by Sentinel during a policy evaluation.

Note: When writing policies using this import, keep in mind that workspace data is generally editable by users outside of the context of policy enforcement. For example, consider the case of omitting the enforcement of policy rules for development workspaces by the workspace name (allowing the policy to pass if the workspace ends in -dev). While this is useful for extremely granular exceptions, the workspace name could be edited by workspace admins, effectively bypassing the policy. In this case, where an extremely strict separation of policy managers vs. workspace practitioners is required, using policy sets to only enforce the policy on non-development workspaces is more appropriate.

Namespace: root

The root namespace contains data associated with the current run.

Value: id

  • Value Type: String.

Specifies the ID that is associated with the current Terraform run.

Value: created_at

  • Value Type: String.

The created_at value within the root namespace specifies the time that the run was created. The timestamp returned follows the format outlined in RFC3339.

Users can use the time import to load a run timestamp and create a new timespace from the specified value. See the time import documentation for available actions that can be performed on timespaces.

Value: created_by

  • Value Type: String.

The created_by value within the root namespace is string that specifies the user name of the HCP Terraform user for the specific run.

Value: message

  • Value Type: String.

Specifies the message that is associated with the Terraform run.

The default value is "Queued manually via the Terraform Enterprise API".

Value: commit_sha

  • Value Type: String.

Specifies the checksum hash (SHA) that identifies the commit.

Value: is_destroy

  • Value Type: Boolean.

Specifies if the plan is a destroy plan, which will destroy all provisioned resources.

Value: refresh

  • Value Type: Boolean.

Specifies whether the state was refreshed prior to the plan.

Value: refresh_only

  • Value Type: Boolean.

Specifies whether the plan is in refresh-only mode, which ignores configuration changes and updates state with any changes made outside of Terraform.

Value: replace_addrs

Provides the targets specified using the -replace flag in the CLI or the replace-addrs attribute in the API. Will be null if no resource targets are specified.

Value: speculative

  • Value Type: Boolean.

Specifies whether the plan associated with the run is a speculative plan only.

Value: target_addrs

Provides the targets specified using the -target flag in the CLI or the target-addrs attribute in the API. Will be null if no resource targets are specified.

To prohibit targeted runs altogether, make sure the target_addrs value is null or empty:

import "tfrun"
 
main = tfrun.target_addrs is null or tfrun.target_addrs is empty

Value: variables

  • Value Type: A string-keyed map of values.

Provides the names of the variables that are configured within the run and the sensitivity state of the value.

variables (map of keys)
└── name (string)
    └── category (string)
    └── sensitive (boolean)

Namespace: project

The project namespace contains data associated with the current run's projects.

Value: id

  • Value Type: String.

Specifies the ID that is associated with the current project.

Value: name

  • Value Type: String.

Specifies the name assigned to the HCP Terraform project.

Namespace: organization

The organization namespace contains data associated with the current run's HCP Terraform organization.

Value: name

  • Value Type: String.

Specifies the name assigned to the HCP Terraform organization.

Namespace: workspace

The workspace namespace contains data associated with the current run's workspace.

Value: id

  • Value Type: String.

Specifies the ID that is associated with the Terraform workspace.

Value: name

  • Value Type: String.

The name of the workspace, which can only include letters, numbers, -, and _.

As an example, in a workspace named app-us-east-dev the following policy would evaluate to true:

# Enforces production rules on all non-development workspaces
 
import "tfrun"
import "strings"
 
# (Actual policy logic omitted)
evaluate_production_policy = rule { ... }
 
main = rule when strings.has_suffix(tfrun.workspace.name, "-dev") is false {
    evaluate_production_policy
}

Value: created_at

  • Value Type: String.

Specifies the time that the workspace was created. The timestamp returned follows the format outlined in RFC3339.

Users can use the time import to load a workspace timestamp, and create a new timespace from the specicied value. See the time import documentation for available actions that can be performed on timespaces.

Value: description

  • Value Type: String.

Contains the description for the workspace.

This value can be null.

Value: auto_apply

  • Value Type: Boolean.

Contains the workspace's auto-apply setting.

Value: tags

  • Value Type: Array of strings.

Contains the list of tag names for the workspace, as well as the keys from tag bindings.

Value: tag_bindings

  • Value Type: Array of objects.

Contains the complete list of tag bindings for the workspace, which includes inherited tag bindings, as well as the workspace key-only tags. Each binding has a string key, a nullable string value, as well as a boolean inherited properties.

tag_bindings (array of objects)
├── key (string)
├── value (string or null)
└── inherited (boolean)

Value: working_directory

  • Value Type: String.

Contains the configured Terraform working directory of the workspace.

This value can be null.

Value: execution_mode

  • Value Type: String.

Contains the configured Terraform execution mode of the workspace.

The default value is remote.

Value: vcs_repo

  • Value Type: A string-keyed map of values.

Contains data associated with a VCS repository connected to the workspace.

Details regarding each attribute can be found in the documentation for the HCP Terraform Workspaces API.

This value can be null.

vcs_repo (map of keys)
├── identifier (string)
├── display_identifier (string)
├── branch (string)
└── ingress_submodules (bool)

Namespace: cost_estimate

The cost_estimation namespace contains data associated with the current run's cost estimate.

This namespace is only present if a cost estimate is available.

Cost estimation is disabled for runs using resource targeting, which may cause unexpected failures.

Note: Cost estimates are not available for Terraform 0.11.

Value: prior_monthly_cost

  • Value Type: String.

Contains the monthly cost estimate at the beginning of a plan.

This value contains a positive decimal and can be "0.0".

Value: proposed_monthly_cost

  • Value Type: String.

Contains the monthly cost estimate if the plan were to be applied.

This value contains a positive decimal and can be "0.0".

Value: delta_monthly_cost

  • Value Type: String.

Contains the difference between the prior and proposed monthly cost estimates.

This value may contain a positive or negative decimal and can be "0.0".
