+## Output Terraform Plan information into a merge request
+
+Using the [GitLab Terraform Report Artifact](../../ci/pipelines/job_artifacts.md#artifactsreportsterraform),
+you can expose details from `terraform plan` runs directly into a merge request widget,
+enabling you to see statistics about the resources that Terraform will create,
+modify, or destroy.
+
+Let's explore how to configure a GitLab Terraform Report Artifact:
+
+1. First, for simplicity, let's define a few reusable variables to allow us to
+   refer to these files multiple times:
+
+   ```yaml
+   variables:
+     PLAN: plan.tfplan
+     PLAN_JSON: tfplan.json
+   ```
+
+1. Next we need to install `jq`, a [lightweight and flexible command-line JSON processor](https://stedolan.github.io/jq/). We will also create an alias for a specific `jq` command that parses out the extact information we want to extract from the `terraform plan` output:
+
+```yaml
+before_script:
+  - apk --no-cache add jq
+  - alias convert_report="jq -r '([.resource_changes[]?.change.actions?]|flatten)|{\"create\":(map(select(.==\"create\"))|length),\"update\":(map(select(.==\"update\"))|length),\"delete\":(map(select(.==\"delete\"))|length)}'"
+```
+
+1. Finally, we define a `script` that runs `terraform plan` and also a `terraform show` which pipes the output and converts the relevant bits into a store variable `PLAN_JSON`. This json is then leveraged to create a [GitLab Terraform Report Artifact](../../ci/pipelines/job_artifacts.md#artifactsreportsterraform).
+
+The terraform report obtains a Terraform tfplan.json file. The collected Terraform plan report will be uploaded to GitLab as an artifact and will be automatically shown in merge requests.
+
+```yaml
+plan:
+  stage: build
+  script:
+    - terraform plan -out=$PLAN
+    - terraform show --json $PLAN | convert_report > $PLAN_JSON
+  artifacts:
+    name: plan
+    paths:
+      - $PLAN
+    reports:
+      terraform: $PLAN_JSON
+```
+
+A full `.gitlab-ci.yaml` file could look like this:
+
+```yaml
+image:
+  name: hashicorp/terraform:light
+  entrypoint:
+    - '/usr/bin/env'
+    - 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'
+
+# Default output file for Terraform plan

+  GITLAB_TF_ADDRESS: ${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/terraform/state/${CI_PROJECT_NAME}

+  - cd ${TF_ROOT}
+  - terraform --version
+  - terraform init -backend-config="address=${GITLAB_TF_ADDRESS}" -backend-config="lock_address=${GITLAB_TF_ADDRESS}/lock" -backend-config="unlock_address=${GITLAB_TF_ADDRESS}/lock" -backend-config="username=${GITLAB_USER_LOGIN}" -backend-config="password=${GITLAB_TF_PASSWORD}" -backend-config="lock_method=POST" -backend-config="unlock_method=DELETE" -backend-config="retry_wait_min=5"

+
+1. Running the pipeline displays the widget in the merge request, like this:
