# Create a multi-account experiment template

**To learn how to create an experiment template via the AWS Management Console**  
See [Create an experiment template](create-template.md).

**To create an experiment template using the CLI**

1. Open the AWS Command Line Interface

1. To create an experiment from a saved JSON file with the account targeting experiment option set to `"multi-account"` (for example, `my-template.json`), replace the placeholder values in *italics* with your own values, and then run the following [create-experiment-template](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/fis/create-experiment-template.html) command.

   ```
   aws fis create-experiment-template --cli-input-json file://my-template.json
   ```

   This will return the experiment template in the response. Copy the `id` from the response, which is the ID of the experiment template.

1. Run the [create-target-account-configuration](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/fis/create-target-account-configuration.html) command to add a target account configuration to the experiment template. Replace the placeholder values in *italics* with your own values, using the `id` from step 2 as the value for the `--experiment-template-id` parameter, and then run the following. The `--description` parameter is optional. Repeat this step for each target account.

   ```
   aws fis create-target-account-configuration --experiment-template-id EXTxxxxxxxxx --account-id 111122223333 --role-arn arn:aws:iam::111122223333:role/role-name --description "my description"
   ```

1. Run the [get-target-account-configuration](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/fis/get-target-account-configuration.html) command to retrieve the details for a specific target account configuration.

   ```
   aws fis get-target-account-configuration --experiment-template-id EXTxxxxxxxxx --account-id 111122223333
   ```

1. Once you have added all your target account configurations, you can run the [list-target-account-configurations](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/fis/list-target-account-configurations.html) command command to see that your target account configurations have been created.

   ```
   aws fis list-target-account-configurations --experiment-template-id EXTxxxxxxxxx
   ```

   You can also verify that you have added target account configurations by running the [get-experiment-template](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/fis/get-experiment-template.html) command. The template will return a read-only field `targetAccountConfigurationsCount` that is a count of all the target account configurations on the experiment template.

1. When you are ready, you can run the experiment template using the [start-experiment](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/fis/start-experiment.html) command.

   ```
   aws fis start-experiment --experiment-template-id EXTxxxxxxxxx
   ```
