Sends a deployment event to Dash0, marking the point in time at which a service was deployed. Deployment events can be overlaid on charts as dashboard annotations, which is what makes "what changed just before this graph moved?" answerable. Attach it to a resource with a lifecycle action_trigger block, or invoke it on its own with terraform apply -invoke. Requires the otlp_url provider attribute (or the DASH0_OTLP_URL environment variable). Requires a static auth_-prefixed auth token: the Dash0 OTLP/HTTP ingress endpoint this action sends to does not accept OAuth access tokens, so credentials resolved from an OAuth-enabled dash0 CLI profile fail with an actionable error. Actions require Terraform 1.14 or later.

Example Usage

terraform

# Deployment events mark the point in time at which a service was deployed, and
# can be overlaid on charts as dashboard annotations. Sending them requires the
# provider's `otlp_url` attribute (or the DASH0_OTLP_URL environment variable).

Schema

Required

dataset (String) The identifier of the Dash0 dataset the event is sent to. Provide the dataset's identifier, which is immutable, not the 'name'.
service_name (String) The name of the deployed service. Maps to the service.name resource attribute.

Optional

body (String) The human-readable message for the event. Defaults to a message derived from service_name, and service_version when set.
deployment_environment_name (String) The environment deployed to, for example "production". Maps to the deployment.environment.name resource attribute.
deployment_id (String) The identifier of the deployment, for example a CI run ID. Maps to the deployment.id resource attribute.
deployment_name (String) The name of the deployment. Maps to the deployment.name resource attribute.
deployment_status (String) The outcome of the deployment, for example "succeeded" or "failed". Maps to the deployment.status log attribute — unlike the other attributes here it describes the event rather than the deployed entity. Note that Terraform cannot report a failed deployment: action_trigger has no after-failure event, so a failed apply emits nothing. Use the dash0 CLI or its send-log-event GitHub Action for failure markers.
event_name (String) The event name. Defaults to dash0.deployment, which is the name Dash0 recognizes as a deployment marker. Override only to emit a related, differently named event.
fail_on_error (Boolean) Whether a delivery failure fails the Terraform run. Defaults to false: an undelivered deployment marker is reported as a warning so that a transient ingestion problem does not fail a deployment, and so that an action wired to before_create cannot block the resource it annotates. Set to true when the marker is load-bearing. Configuration mistakes (a missing otlp_url or an OAuth token) always fail regardless of this setting, since none of them survive a retry.
log_attributes (Map of String) Additional log record attributes, merged with deployment_status. Dedicated attributes take precedence.
resource_attributes (Map of String) Additional resource attributes, merged with the ones derived from the dedicated attributes above. Dedicated attributes take precedence, so a key set here cannot silently shadow one of them.
service_namespace (String) The namespace of the deployed service. Maps to the service.namespace resource attribute.
service_version (String) The version of the deployed service, for example an image tag or release number. Maps to the service.version resource attribute.
severity_number (Number) The OpenTelemetry severity number (1–24). Defaults to 9 (INFO), which is what a deployment marker is.
time (String) The event timestamp as an RFC3339 timestamp with optional nanoseconds (for example "2024-03-15T10:30:00.123456789Z"). Defaults to the time the action is invoked, which is normally what you want for a deployment marker.
vcs_ref_head_name (String) The name of the deployed ref, for example a branch or tag name. Maps to the vcs.ref.head.name log record attribute.
vcs_ref_head_revision (String) The deployed revision, for example a commit SHA. Maps to the vcs.ref.head.revision log record attribute.
vcs_repository_url (String) The URL of the repository the deployed revision came from. Maps to the vcs.repository.url.full log record attribute.
