Machine-Readable UI

Note: This format is available in Terraform 0.15.3 and later.

By default, many Terraform commands display UI output as unstructured text, intended to be read by a user via a terminal emulator. This text stream is not a stable interface for integrations. Some commands support a -json flag, which enables a structured JSON output mode with a defined interface.

For long-running commands such as plan, apply, refresh, and test, the -json flag outputs a stream of JSON UI messages, one per line. These can be processed one message at a time, with integrating software filtering, combining, or modifying the output as desired.

The first message output has type version, and includes a ui key, which as of Terraform 1.1.0 has value "1.0". The semantics of this version are:

We will increment the minor version, e.g. "1.1", for backward-compatible changes or additions. Ignore any object properties with unrecognized names to remain forward-compatible with future minor versions.
We will increment the major version, e.g. "2.0", for changes that are not backward-compatible. Reject any input which reports an unsupported major version.

We will introduce new major versions only within the bounds of the Terraform 1.0 Compatibility Promises.

Sample JSON Output

Below is sample output from running terraform apply -json:

Each line consists of a JSON object with several keys common to all messages. These are:

@level: this is normally "info", but can be "error" or "warn" when showing diagnostics
@message: a human-readable summary of the contents of this message
@module: always "terraform.ui" when rendering UI output
@timestamp: an RFC3339 timestamp of when the message was output
type: defines which kind of message this is and determines how to interpret other keys which may be present

Clients presenting the logs as a user interface should handle unexpected message types by presenting at least the @message field to the user.

Messages will be emitted as events occur to trigger them. This means that messages related to several resources may be interleaved (if Terraform is running with concurrency above 1). The resource object value can be used to link multiple messages about a single resource.

Message Types

The following message types are supported:

Generic Messages

version: information about the Terraform version and the version of the schema used for the following messages
log: unstructured human-readable log lines
diagnostic: diagnostic warning or error messages; see the terraform validate docs for more details on the format

Operation Results

resource_drift: describes a detected change to a single resource made outside of Terraform
planned_change: describes a planned change to a single resource
change_summary: summary of all planned or applied changes
outputs: list of all root module outputs

Resource Progress

apply_start, apply_progress, apply_complete, apply_errored: sequence of messages indicating progress of a single resource through apply
provision_start, provision_progress, provision_complete, provision_errored: sequence of messages indicating progress of a single provisioner step
refresh_start, refresh_complete: sequence of messages indicating progress of a single resource through refresh

Test Results

test_abstract: describes the test operation that Terraform executes
test_file: describes the status of a completed test file
test_run: describes the status of a completed run block within a test file
test_cleanup: describes the result of the test cleanup after a completed test file
test_summary: describes the overall status of the completed test operation
test_plan: describes the output of a given run block when command = plan
test_state: describes the output of a given run block when command = apply
test_interrupt: describes the result of an interrupted test operation

Version Message

A machine-readable UI command output will always begin with a version message. The following message-specific keys are defined:

terraform: the Terraform version which emitted this message
ui: the machine-readable UI schema version defining the meaning of the following messages

Example

{  "@level": "info",  "@message": "Terraform 0.15.4",  "@module": "terraform.ui",  "@timestamp": "2021-05-25T13:32:41.275359-04:00",  "terraform": "0.15.4",  "type": "version",  "ui": "0.1.0"}

Resource Drift

If drift is detected during planning, Terraform will emit a resource_drift message for each resource which has changed outside of Terraform. This message has an embedded change object with the following keys:

resource: object describing the address of the resource to be changed; see resource object below for details
action: the action planned to be taken for the resource. Values: update, delete.

This message does not include details about the exact changes which caused the change to be planned. That information is available in the JSON plan output.

Example

{  "@level": "info",  "@message": "random_pet.animal: Drift detected (update)",  "@module": "terraform.ui",  "@timestamp": "2021-05-25T13:32:41.705503-04:00",  "change": {    "resource": {      "addr": "random_pet.animal",      "module": "",      "resource": "random_pet.animal",      "implied_provider": "random",      "resource_type": "random_pet",      "resource_name": "animal",      "resource_key": null    },    "action": "update"  },  "type": "resource_drift"}

Planned Change

At the end of a plan or before an apply, Terraform will emit a planned_change message for each resource which has changes to apply. This message has an embedded change object with the following keys:

resource: object describing the address of the resource to be changed; see resource object below for details
previous_resource: object describing the previous address of the resource, if this change includes a configuration-driven move
action: the action planned to be taken for the resource. Values: noop, create, read, update, replace, delete, move.
reason: an optional reason for the change, only used when the action is replace or delete. Values:
- tainted: resource was marked as tainted
- requested: user requested that the resource be replaced, for example via the -replace plan flag
- cannot_update: changes to configuration force the resource to be deleted and created rather than updated
- delete_because_no_resource_config: no matching resource in configuration
- delete_because_wrong_repetition: resource instance key has no corresponding count or for_each in configuration
- delete_because_count_index: resource instance key is outside the range of the count argument
- delete_because_each_key: resource instance key is not included in the for_each argument
- delete_because_no_module: enclosing module instance is not in configuration

This message does not include details about the exact changes which caused the change to be planned. That information is available in the JSON plan output.

Example

{  "@level": "info",  "@message": "random_pet.animal: Plan to create",  "@module": "terraform.ui",  "@timestamp": "2021-05-25T13:32:41.705503-04:00",  "change": {    "resource": {      "addr": "random_pet.animal",      "module": "",      "resource": "random_pet.animal",      "implied_provider": "random",      "resource_type": "random_pet",      "resource_name": "animal",      "resource_key": null    },    "action": "create"  },  "type": "planned_change"}

Change Summary

Terraform outputs a change summary when a plan or apply operation completes. Both message types include a changes object, which has the following keys:

add: count of resources to be created (including as part of replacement)
change: count of resources to be changed in-place
remove: count of resources to be destroyed (including as part of replacement)
operation: one of plan, apply, or destroy

Example

{  "@level": "info",  "@message": "Apply complete! Resources: 1 added, 0 changed, 0 destroyed.",  "@module": "terraform.ui",  "@timestamp": "2021-05-25T13:32:41.869168-04:00",  "changes": {    "add": 1,    "change": 0,    "remove": 0,    "operation": "apply"  },  "type": "change_summary"}

Outputs

After a successful plan or apply, a message with type outputs contains the values of all root module output values. This message contains an outputs object, the keys of which are the output names. The outputs values are objects with the following keys:

action: for planned outputs, the action which will be taken for the output. Values: noop, create, update, delete
value: for applied outputs, the value of the output, encoded in JSON
type: for applied outputs, the detected HCL type of the output value
sensitive: boolean value, true if the output is sensitive and should be hidden from UI by default

Note that sensitive outputs still include the value field, and integrating software should respect the sensitivity value as appropriate for the given use case.

Example

{  "@level": "info",  "@message": "Outputs: 1",  "@module": "terraform.ui",  "@timestamp": "2021-05-25T13:32:41.869280-04:00",  "outputs": {    "pets": {      "sensitive": false,      "type": "string",      "value": "smart-lizard"    }  },  "type": "outputs"}

Operation Messages

Performing Terraform operations to a resource will often result in several messages being emitted. The message types include:

apply_start: when starting to apply changes for a resource
apply_progress: periodically, showing elapsed time output
apply_complete: on successful operation completion
apply_errored: when an error is encountered during the operation
provision_start: when starting a provisioner step
provision_progress: on provisioner output
provision_complete: on successful provisioning
provision_errored: when an error is enountered during provisioning
refresh_start: when reading a resource during refresh
refresh_complete: on successful refresh

Each of these messages has a hook object, which has different fields for each type. All hooks have a resource object which identifies which resource is the subject of the operation.

The apply_start message hook object has the following keys:

resource: a resource object identifying the resource
action: the action to be taken for the resource. Values: noop, create, read, update, replace, delete

Resource Object

The resource object is a decomposed structure representing a resource address in configuration, which is used to identify which resource a given message is associated with. The object has the following keys:

addr: the full unique address of the resource as a string
module: the address of the module containing the resource, in the form module.foo.module.bar, or an empty string for a root module resource
resource: the module-relative address, which is identical to addr for root module resources
resource_type: the type of resource being addressed
resource_name: the name label for the resource
resource_key: the address key (count or for_each value), or null if the neither are used
implied_provider: the provider type implied by the resource type; this may not reflect the resource's provider if provider aliases are used

Example

{  "addr": "module.pets.random_pet.pet[\"friend\"]",  "module": "module.pets",  "resource": "random_pet.pet[\"friend\"]",  "implied_provider": "random",  "resource_type": "random_pet",  "resource_name": "pet",  "resource_key": "friend"}

Test Abstract

The terraform test command emits a test_abstract message describing the test files and run blocks that Terraform executes during the upcoming operation.

Example

{  "@level": "info",  "@message": "Found 1 file and 2 run blocks",  "@module": "terraform.ui",  "@timestamp": "2023-08-09T16:12:30.325582+02:00",  "test_abstract": {    "validation.tftest.hcl": [      "passed_validation",      "failed_validatation"    ]  },  "type": "test_abstract"}

Test File

Throughout a terraform test execution, Terraform will produce several progress updates for each test file. The progress field can be starting, teardown, or complete. Each test file will emit each progress update exactly once. When a test file emits the complete progress update, it will also include a status field containing one of pass, error, fail, or skip denoting the overall status of the completed test file.

Example

{  "@level": "info",  "@message": "main.tftest.hcl... pass",  "@module": "terraform.ui",  "@testfile": "validation.tftest.hcl",  "@timestamp": "2023-08-09T16:12:30.724368+02:00",  "test_file": {    "path": "validation.tftest.hcl",    "progress": "complete",    "status": "pass"  },  "type": "test_file"}

Test Run

While executing run blocks within a test file, Terraform will also produce several status updates for each run block. The progress field for a run block progress update can be starting, running, teardown, and complete. The starting and complete progress updates will be emitted exactly once. While the running and teardown progress updates can be emitted multiple times.

The starting, running and teardown updates will also include an elapsed field indicating the number of milliseconds the current test operation (for starting and running) or the current destroy operation (for teardown) has been in progress.

The complete progress update will also include a status field containing one of pass, error, fail, or skip denoting the overall status of the completed run block`.

Not every run block will emit teardown progress updates, as only the most recently executed run blocks reference the latest in-memory state files that need to be torn down. In addition, the run block tear down process is only initiated once the overall test file has already emitted its teardown status update. This means you can expect the complete progress update to be issued for a run block before any teardown updates are provided. There will always be a complete progress update issued by the enclosing test file when the tear down process for all run blocks is complete.

Examples

{  "@level": "info",  "@message": "  \"successful_validation\"... pass",  "@module": "terraform.ui",  "@testfile": "validation.tftest.hcl",  "@testrun": "successful_validation",  "@timestamp": "2023-08-09T16:12:30.724407+02:00",  "test_run": {    "path": "main.tftest.hcl",    "run": "successful_validation",    "progress": "complete",    "status": "pass"  },  "type": "test_run"}

{  "@level": "info",  "@message": "  \"successful_validation\"... in progress",  "@module": "terraform.ui",  "@testfile": "validation.tftest.hcl",  "@testrun": "successful_validation",  "@timestamp": "2023-08-09T16:12:30.724407+02:00",  "test_run": {    "path": "main.tftest.hcl",    "run": "successful_validation",    "progress": "running",    "elapsed": 2024  },  "type": "test_run"}

Test Cleanup

After Terraform completes the execution of each test file, terraform test may emit a series of test_cleanup messages detailing any state it could not destroy. You must locate and destroy the resources listed in these resources manually.

As the test framework can manage multiple state files for each test file, you can see multiple versions of this message for each state file that holds resources that Terraform could not destroy. Using the @testrun field, you can pinpoint the run block that last updated the state file to locate the resources that Terraform could not destroy.

Example

{  "@level": "info",  "@message": "Terraform left some resources in state after executing main.tftest.hcl, they need to be cleaned up manually.",  "@module": "terraform.ui",  "@testfile": "validation.tftest.hcl",  "@testrun": "successful_validation",  "@timestamp": "2023-08-09T16:12:30.724407+02:00",  "test_cleanup": {    "failed_resources": [      {        "instance": "aws_instance.primary"      },      {         "instance": "aws_instance.secondary"      }    ]  },  "type": "test_cleanup"}

Test Summary

After the test operation has completed all test files, terraform test emits a test_summary message with the status of the overall test operation.

Example

{  "@level": "info",  "@message": "Success! 2 passed, 0 failed.",  "@module": "terraform.ui",  "@timestamp": "2023-08-09T16:26:45.482070+02:00",  "test_summary": {    "status": "pass",    "passed": 2,    "failed": 0,    "errored": 0,    "skipped": 0  },  "type": "test_summary"}

Test Plan

In -verbose mode, terraform test emits a test_plan message for all run blocks that executed a plan operation. The test_plan message contains a subset of the attributes from the terraform show -json <planfile> command output and the terraform providers schema -json command output.

The message contains the following fields representing the plan: plan_format_version, output_changes, resource_changes, resource_drift and relevant_attributes. These match the respective fields in the JSON Plan Representation.

The message contains the following fields representing the provider schemas: provider_format_version and provider_schemas. These match the respective fields in the JSON Providers Schema Representation.

Test State

In -verbose mode, terraform test emits a test_state message for all run blocks that executed an apply operation. The test_state message contains a subset of the terraform show -json command output and the terraform providers schema -json command output.

The message contains the following fields representing the state: state_format_version, root_module, and outputs. These match the respective fields in the JSON Values Representation that are embedded in complete JSON state representation.

Example

{  "@level": "info",  "@message": "-verbose flag enabled, printing state",  "@module": "terraform.ui",  "@testfile": "validation.tftest.hcl",  "@testrun": "successful_validation",  "@timestamp": "2023-08-09T17:18:21.173008+02:00",  "test_state": {    "state_format_version": "1.0",    "root_module": {      "resources": [        {          "address": "aws_instance.primary",          "mode": "managed",          "type": "aws_instance",          "name": "primary",          "provider_name": "registry.terraform.io/hashicorp/aws",          "schema_version": 0,          "values": {            "ami": "af84f887-e3eb-9e52-5f8b-8a2803734fd0"          },          "sensitive_values": {}        }      ]    },    "provider_format_version": "1.0",    "provider_schemas": {      "registry.terraform.io/hashicorp/aws": {        "provider": {          "version": 0        },        "resource_schemas": {          "aws_instance": {            "version": 0,            "block": {              "attributes": {                "ami": {                  "type": "string",                  "description_kind": "plain",                  "required": true                }              },              "description_kind": "plain"            }          }        }      }    }  },  "type": "test_state"}

Test Interrupt

When terraform test is impeded or canceled, it emits a test_interrupt message that describes the interrupted operation. This message includes any state that Terraform could not destroy before exiting and any leftover resources that Terraform did not finish creating.

As with the Test Cleanup message, Terraform might have been maintaining multiple state files. The state field contains the resources from the main state for the test configuration, while the states field contains a map of run block names to the resources that each run block created, which Terraform could not destroy.

Finally, the planned field contains any resources that were in the process of being created by the interrupted run block, which you can identify using the @testrun field.

Example

{  "@level": "info",  "@message": "-verbose flag enabled, printing state",  "@module": "terraform.ui",  "@testfile": "validation.tftest.hcl",  "@testrun": "successful_validation",  "@timestamp": "2023-08-09T17:18:21.173008+02:00",  "test_interrupt": {    "state": [      {        "instance": "aws_instance.primary"      }    ],    "states": {      "unsuccessful_validation": [        {          "instance": "aws_instance.secondary"        }      ]    },    "planned": [      "aws_instance.secondary"    ]  },  "type": "test_interrupt"}
