Test Your Cloud Template Deployment

To test the deployment of a cloud template, you use the Blueprint APIs to make a POST request with the cloud template ID as input.

Before deploying a cloud template, you can test the syntax and placement of your cloud template to ensure deployment viability. If errors are reported in the test, you must fix the errors and test again before deploying the cloud template.

Prerequisites

Verify that all general prerequisites and prerequisites for the Cloud Assembly Blueprint service have been satisfied. See Prerequisites for API Use Case Examples.
Verify that the flavor mapping and image mapping specified in the released vRealize Automation Cloud cloud template version exist in your cloud account. See Create Flavor Mappings and Create Image Mappings.
Verify that you have the ID for the cloud template you want to deploy. See Create and Update a Cloud Template.

Procedure

Assign the cloud template ID variable.
```
cloud_template_id='<your_cloud_template_id>'
```
Assign image mapping and flavor mapping variables for the cloud template you intend to deploy.
```
image_mapping='<your_image_mapping_name>'
flavor_mapping='<your_flavor_mapping_name>'
```
The image mapping specifies the OS image for a VM. The flavor mapping specifies the CPU count and RAM of a VM.

Test the cloud template deployment.

curl -X POST \
  $url/blueprint/api/blueprint-requests?apiVersion=$api_version \
  -H "Authorization: Bearer $access_token" \
  -H 'Content-Type: application/json' \
  -d '{
    "simulate":true,
    "blueprintId": "'"$cloud_template_id"'",
    "inputs": {
        "count": 2,
        "image":"'"$image_mapping"'",
        "flavor":"'"$flavor_mapping"'"
    }
}' | jq "."

Examine the response and assign the cloud template request ID.
```
cloud_template_request_id='<your_cloud_template_request_id>'
```

Get the status of the test request.

curl -X GET \
  $url/blueprint/api/blueprint-requests/$cloud_template_request_id?apiVersion=$api_version \
  -H "Authorization: Bearer $access_token" | jq "."

Example: Test a Deployment

For a cloud template with ID 1f170637-81a3-4257-b1cd-b2219ee8034c, test the deployment with image mapping set to ubuntu and flavor mapping set to small.

Assign variables.

Note: If your organization uses an API service that is hosted outside of the United States, your URL variable must include a country abbreviation. See Regional Endpoints for vRealize Automation Cloud APIs.

$ url='https://api.mgmt.cloud.vmware.com'
$ api_version='2019-09-12'
$ cloud_template_id='1f170637-81a3-4257-b1cd-b2219ee8034c'
$ image_mapping='ubuntu'
$ flavor_mapping='small'

Test the cloud template deployment.

$ curl -X POST \
  $url/blueprint/api/blueprint-requests?apiVersion=$api_version \
  -H "Authorization: Bearer $access_token" \
  -H 'Content-Type: application/json' \
  -d '{
    "simulate":true,
    "blueprintId": "'"$cloud_template_id"'",
    "inputs": {
        "count": 2,
        "image":"'"$image_mapping"'",
        "flavor":"'"$flavor_mapping"'"
    }
}' | jq "."

A snippet of the response shows the cloud template request ID.

{  
  "id": "5c33355e-fc52-4a30-97c3-3752cf9b644e",
  "createdAt": "2019-10-11T00:11:55.544Z",
...
  "blueprintId": "1f170637-81a3-4257-b1cd-b2219ee8034c",
...

Assign the cloud template request ID variable.

$ cloud_template_request_id='5c33355e-fc52-4a30-97c3-3752cf9b644e'

Request the status of the deployment.

$ curl -X GET \
  $url/blueprint/api/blueprint-requests/$cloud_template_request_id?apiVersion=$api_version \
  -H "Authorization: Bearer $access_token" | jq "."

A snippet of the response shows the status of the deployment test request.

...
  "blueprintId": "1f170637-81a3-4257-b1cd-b2219ee8034c",
  "inputs": {
    "count": 2,
    "image": "ubuntu",
    "flavor": "small"
  },
  "status": "FINISHED",
...

What to do next

If your test deployment is successful, you are ready to deploy your cloud template.
