# Create an Amazon ECS Compute Platform deployment (CLI)
<a name="deployments-create-ecs-cli"></a>

After you have created the application and revision (in Amazon ECS deployments, this is the AppSpec file):

Call the [create-deployment](https://docs.aws.amazon.com/cli/latest/reference/deploy/create-deployment.html) command, specifying:
+ An application name. To view a list of application names, call the [list-applications](https://docs.aws.amazon.com/cli/latest/reference/deploy/list-applications.html) command.
+ A deployment group name. To view a list of deployment group names, call the [list-deployment-groups](https://docs.aws.amazon.com/cli/latest/reference/deploy/list-deployment-groups.html) command.
+ Information about the revision to be deployed:

  For revisions stored in Amazon S3:
  + The Amazon S3 bucket name that contains the revision.
  + The name of the uploaded revision.
  + (Optional) The Amazon S3 version identifier for the revision. (If the version identifier is not specified, CodeDeploy uses the most recent version.)
  + (Optional) The ETag for the revision. (If the ETag is not specified, CodeDeploy skips object validation.)

  For revisions stored in a file that is not in Amazon S3, you need the file name and its path. Your revision file is written using JSON or YAML, so it most likely has a .json or .yaml extension.
+ (Optional) A description for the deployment.

The revision file can be specified as a file uploaded to an Amazon S3 bucket or as a string. The syntax for each when used as part of the **create-deployment** command is:
+ Amazon S3 bucket:

  The `version` and `eTag` are optional.

  ```
  --s3-location bucket=string,key=string,bundleType=JSON|YAML,version=string,eTag=string
  ```
+ String:

  ```
  --revision '{"revisionType": "String", "string": {"content":"revision-as-string"}}'
  ```

**Note**  
The **create-deployment** command can load a revision from a file. For more information, see [Loading parameters from a file](https://docs.aws.amazon.com/cli/latest/userguide/cli-using-param.html#cli-using-param-file). 

For AWS Lambda deployment revision templates, see [Add an AppSpec file for an AWS Lambda deployment](application-revisions-appspec-file.md#add-appspec-file-lambda). For an example revision, see [AppSpec File example for an AWS Lambda deployment](reference-appspec-file-example.md#appspec-file-example-lambda).

To track the status of your deployment, see [View CodeDeploy deployment details](deployments-view-details.md).
