# Working with public parameters in Parameter Store
Some AWS services publish information about common artifacts as AWS Systems Manager *public* parameters. For example, the Amazon Elastic Compute Cloud (Amazon EC2) service publishes information about Amazon Machine Images (AMIs) as public parameters.

# Discovering public parameters in Parameter Store
You can search for public parameters using the Parameter Store console or the AWS Command Line Interface.
A public parameter name begins with `aws/service/list`. The next part of the name corresponds to the service that owns that parameter.
The following is a partial list of AWS services and other resources that provide public parameters:
+ `ami-amazon-linux-latest`
+ `ami-windows-latest`
+ `ec2-macos`
+ `appmesh`
+ `aws-for-fluent-bit`
+ `aws-sdk-pandas`
+ `bottlerocket`
+ `canonical`
+ `cloud9`
+ `datasync`
+ `deeplearning`
+ `ecs`
+ `eks`
+ `fis`
+ `freebsd`
+ `global-infrastructure`
+ `marketplace`
+ `neuron`
+ `powertools`
+ `sagemaker-distribution`
+ `storagegateway`
Not all public parameters are published to every AWS Region.
## Finding public parameters using the Parameter Store console
You must have at least one parameter in your AWS account and AWS Region before you can search for public parameters using the console.
**To find public parameters using the console**
1. Open the AWS Systems Manager console at [https://console.aws.amazon.com/systems-manager/](https://console.aws.amazon.com/systems-manager/).
1. In the navigation pane, choose **Parameter Store**.
1. Choose the **Public parameters** tab.
1. Choose the **Select a service** dropdown. Choose the service whose parameters you want to use.
1. (Optional) Filter the parameters owned by the service you selected by entering more information into the search bar.
1. Choose the public parameter you want to use.
## Finding public parameters using the AWS CLI
Use `describe-parameters` for discovery of public parameters.
Use `get-parameters-by-path` to get the actual path for a service listed under `/aws/service/list`. To get the service's path, remove `/list` from the path. For example, `/aws/service/list/ecs` becomes `/aws/service/ecs`.
To retrieve a list of public parameters owned by different services in Parameter Store, run the following command.
```
aws ssm get-parameters-by-path --path /aws/service/list
```
The command returns information like the following. This example has been truncated for space.
```

"DataType": "text"
}
]
}
```
If you want to view parameters owned by a specific service, choose the service from the list that was produced after running the earlier command. Then, make a `get-parameters-by-path` call using the name of your desired service.
For example, `/aws/service/global-infrastructure`. The path might be one-level (only calls parameters that match the exact values given) or recursive (contains elements in the path beyond what you have given).
**Note**
The `/aws/service/global-infrastructure` path is not supported for queries in all Regions. For information, see [Calling public parameters for AWS services, Regions, endpoints, Availability Zones, local zones, and Wavelength Zones in Parameter Store](parameter-store-public-parameters-global-infrastructure.md).
If no results are returned for the service you specify, add the `--recursive` flag and run the command again.
```
aws ssm get-parameters-by-path --path /aws/service/global-infrastructure
```
This returns all parameters owned by `global-infrastructure`. The following is an example.
```
{
"Parameters": [
{
"Name": "/aws/service/global-infrastructure/current-region",
"Type": "String",
"LastModifiedDate": "2019-06-21T05:15:34.252000-07:00",
"Version": 1,
"Tier": "Standard",

"Version": 1,
"Tier": "Standard",
"Policies": [],
"DataType": "text"
}
]
}
```
You can also view parameters owned by a specific service by using the `Option:BeginsWith` filter.
```
aws ssm describe-parameters --parameter-filters "Key=Name, Option=BeginsWith, Values=/aws/service/ami-amazon-linux-latest"
```
The command returns information like the following. This example output has been truncated for space.
```
{

{

}
]
}
```
**Note**
The returned parameters might be different when you use `Option=BeginsWith` because it uses a different search pattern.

# Calling the ECS optimized AMI public parameter in Parameter Store
The Amazon Elastic Container Service (Amazon ECS) service publishes the name of the latest Amazon ECS optimized Amazon Machine Images (AMIs) as public parameters. Users are encouraged to use this AMI when creating a new Amazon Elastic Compute Cloud (Amazon EC2) cluster for Amazon ECS because the optimized AMIs include bug fixes and feature updates.
Use the following command to view the name of the latest Amazon ECS optimized AMI for Amazon Linux 2. To see commands for other operating systems, see [Retrieving Amazon ECS-Optimized AMI metadata ](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/retrieve-ecs-optimized_AMI.html) in the *Amazon Elastic Container Service Developer Guide*.

# Calling the EKS optimized AMI public parameter in Parameter Store
The Amazon Elastic Kubernetes Service (Amazon EKS) service publishes the name of the latest Amazon EKS optimized Amazon Machine Image (AMI) as a public parameter. We encourage you to use this AMI when adding nodes to an Amazon EKS cluster, as new releases include Kubernetes patches and security updates. Previously, to guarantee you were using the latest AMI meant checking the Amazon EKS documentation and manually updating any deployment templates or resources with the new AMI ID.
Use the following command to view the name of the latest Amazon EKS optimized AMI for Amazon Linux 2.

# Calling public parameters for AWS services, Regions, endpoints, Availability Zones, local zones, and Wavelength Zones in Parameter Store
You can call the AWS Region, service, endpoint, Availability, and Wavelength Zones of public parameters by using the following path.
`/aws/service/global-infrastructure`
**Note**
Currently, the path `/aws/service/global-infrastructure` is supported for queries in the following AWS Regions only:
US East (N. Virginia) (us-east-1)
US East (Ohio) (us-east-2)
US West (N. California) (us-west-1)
US West (Oregon) (us-west-2)
Asia Pacific (Hong Kong) (ap-east-1)
Asia Pacific (Mumbai) (ap-south-1)
Asia Pacific (Seoul) (ap-northeast-2)
Asia Pacific (Singapore) (ap-southeast-1)
Asia Pacific (Sydney) (ap-southeast-2)
Asia Pacific (Tokyo) (ap-northeast-1)
Canada (Central) (ca-central-1)
Europe (Frankfurt) (eu-central-1)
Europe (Ireland) (eu-west-1)
Europe (London) (eu-west-2)
Europe (Paris) (eu-west-3)
Europe (Stockholm) (eu-north-1)
South America (São Paulo) (sa-east-1)
If you are working in a different [commercial Region](https://docs.aws.amazon.com/glossary/latest/reference/glos-chap.html#region), you can specify a supported Region in your query to view results. For example, if you are working in the Canada West (Calgary) (ca-west-1) Region, you could specify Canada (Central) (ca-central-1) in your query:
```
aws ssm get-parameters-by-path \
--path /aws/service/global-infrastructure/regions \
--region ca-central-1
```
**View active AWS Regions**
