Create a Systems Manager parameter (AWS CLI)

You can use the AWS CLI to create String, StringList, and SecureString parameter types.

For more information about using the AWS CLI to create parameters, see Walkthrough: Create and update a String parameter (AWS CLI).

Note

Parameters are only available in the AWS Region where they were created.

Parameters can't be referenced or nested in the values of other parameters. You can't include {{}} or {{ssm:parameter-name}} in a parameter value.

Create a `String` Parameter (AWS CLI)

Install and configure the AWS CLI, if you have not already.

For information, see Install or upgrade AWS command line tools.
Run the following command to create a parameter that contains a plain text value.
Linux
```
aws ssm put-parameter \
    --name "parameter-name" \    
    --value "parameter-value" \
    --type String \
    --tags "Key=tag-key,Value=tag-value"
```
Windows
```
aws ssm put-parameter ^
    --name "parameter-name" ^    
    --value "parameter-value" ^
    --type String ^
    --tags "Key=tag-key,Value=tag-value"
```

Run the following command to create a parameter that contains an Amazon Machine Image (AMI) ID as the parameter value.
Linux
```
aws ssm put-parameter \
    --name "parameter-name" \
    --value "an-AMI-id" \
    --type String \
    --data-type "aws:ec2:image" \
    --tags "Key=tag-key,Value=tag-value"
```
Windows
```
aws ssm put-parameter ^
    --name "parameter-name" ^
    --value "an-AMI-id" ^
    --type String ^
    --data-type "aws:ec2:image" ^
    --tags "Key=tag-key,Value=tag-value"
```
The --data-type option must be specified only if you are creating a parameter that contains an AMI ID. For all other parameters, the default data type is text. For more information, see Native parameter support for Amazon Machine Image IDs.

Important

If successful, the command returns the version number of the parameter. Exception: If you have specified aws:ec2:image as the data type, a new version number in the response does not mean that the parameter value has been validated yet. For more information, see Native parameter support for Amazon Machine Image IDs.

The following example adds two key-value pair tags to a parameter.
Linux
```
aws ssm put-parameter \
    --name parameter-name \
    --value "parameter-value" \
    --type "String" \
    --tags '[{"Key":"Region","Value":"East"},{"Key":"Environment", "Value":"Production"}]'
```
Windows
```
aws ssm put-parameter ^
    --name parameter-name ^
    --value "parameter-value" ^
    --type "String" ^
    --tags [{\"Key\":\"Region1\",\"Value\":\"East1\"},{\"Key\":\"Environment1\",\"Value\":\"Production1\"}]
```
Run the following command to verify the details of the parameter.
```
aws ssm get-parameters --name "parameter-name"
```

Create a `StringList` parameter (AWS CLI)

Install and configure the AWS CLI, if you have not already.

For information, see Install or upgrade AWS command line tools.
Run the following command to create a parameter.
Linux
```
aws ssm put-parameter \
    --name "parameter-name" \
    --value "a-comma-separated-list-of-values" \
    --type StringList \
    --tags "Key=tag-key,Value=tag-value"
```
Windows
```
aws ssm put-parameter ^
    --name "parameter-name" ^
    --value "a-comma-separated-list-of-values" ^
    --type StringList ^
    --tags "Key=tag-key,Value=tag-value"
```
Note

If successful, the command returns the version number of the parameter.

This example adds two key-value pair tags to a parameter. (Depending on the operating system type on your local machine, run one of the following commands. The version to run from a local Windows machine includes the escape characters ("\") that you need to run the command from your command line tool.)

Here is a StringList example that uses a parameter hierarchy.
Linux
```
aws ssm put-parameter \
    --name /IAD/ERP/Oracle/addUsers \
    --value "Milana,Mariana,Mark,Miguel" \
    --type StringList
```
Windows
```
aws ssm put-parameter ^
    --name /IAD/ERP/Oracle/addUsers ^
    --value "Milana,Mariana,Mark,Miguel" ^
    --type StringList
```
Note

Items in a StringList must be separated by a comma (,). You can't use other punctuation or special character to escape items in the list. If you have a parameter value that requires a comma, then use the String type.
Run the get-parameters command to verify the details of the parameter. For example:
```
aws ssm get-parameters --name "/IAD/ERP/Oracle/addUsers"
```

Create a SecureString parameter (AWS CLI)

Before you create a SecureString parameter, read about the requirements for this type of parameter. For more information, see SecureString parameters.

Install and configure the AWS CLI, if you have not already.

For information, see Install or upgrade AWS command line tools.

Run the following command to create a parameter.

Note

To use the AWS Key Management Service (KMS) customer master key (CMK) assigned to your account, remove the key-id parameter from the command. For more information about CMKs, see AWS Key Management Service Concepts in the AWS Key Management Service Developer Guide.

The following example uses an obfuscated name (3l3vat3131) for a password parameter and a CMK.

Run the following command to verify the details of the parameter.
Linux
```
aws ssm get-parameters \
    --name "the-parameter-name-you-specified" \   
    --with-decryption
```
Windows
```
aws ssm get-parameters ^
    --name "the-parameter-name-you-specified" ^   
    --with-decryption
```
Note

If you don't specify the with-decryption parameter, or if you specify the no-with-decryption parameter, the command returns an encrypted GUID.
