# Use `CreateGroup` with a CLI
<a name="resource-groups_example_resource-groups_CreateGroup_section"></a>

The following code examples show how to use `CreateGroup`.

------
#### [ CLI ]

**AWS CLI**  
**Example 1: To create a tag-based resource group**  
The following `create-group` example creates a tag-based resource group of Amazon EC2 instances in the current region. It's based on a query for resources that are tagged with the key `Name`, and the value `WebServers`. The group name is `tbq-WebServer`. The query is in a separate JSON file that is passed to the command.  

```
aws resource-groups create-group \
    --name tbq-WebServer \
    --resource-query file://query.json
```
Contents of `query.json`:  

```
{
    "Type": "TAG_FILTERS_1_0",
    "Query": "{\"ResourceTypeFilters\":[\"AWS::EC2::Instance\"],\"TagFilters\":[{\"Key\":\"Name\", \"Values\":[\"WebServers\"]}]}"
}
```
Output:  

```
{
    "Group": {
        "GroupArn": "arn:aws:resource-groups:us-west-2:123456789012:group/tbq-WebServer",
        "Name": "tbq-WebServer"
    },
    "ResourceQuery": {
        "Type": "TAG_FILTERS_1_0",
        "Query": "{\"ResourceTypeFilters\":[\"AWS::EC2::Instance\"],\"TagFilters\":[{\"Key\":\"Name\", \"Values\":[\"WebServers\"]}]}"
    }
}
```
**Example 2: To create a CloudFormation stack-based resource group**  
The following `create-group` example creates an AWS CloudFormation stack-based resource group named `sampleCFNstackgroup`. The query includes all resources in the specified CloudFormation stack that are supported by AWS Resource Groups.  

```
aws resource-groups create-group \
    --name cbq-CFNstackgroup \
    --resource-query file://query.json
```
Contents of `query.json`:  

```
{
    "Type": "CLOUDFORMATION_STACK_1_0",
    "Query": "{\"ResourceTypeFilters\":[\"AWS::AllSupported\"],\"StackIdentifier\":\"arn:aws:cloudformation:us-west-2:123456789012:stack/MyCFNStack/1415z9z0-z39z-11z8-97z5-500z212zz6fz\"}"
}
```
Output:  

```
{
    "Group": {
        "GroupArn": "arn:aws:resource-groups:us-west-2:123456789012:group/cbq-CFNstackgroup",
        "Name": "cbq-CFNstackgroup"
    },
    "ResourceQuery": {
        "Type": "CLOUDFORMATION_STACK_1_0",
        "Query": "{\"ResourceTypeFilters\":[\"AWS::AllSupported\"],\"StackIdentifier\":\"arn:aws:cloudformation:us-east-2:123456789012:stack/MyCFNStack/1415z9z0-z39z-11z8-97z5-500z212zz6fz\"}"}'
    }
}
```

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example creates a new tag-based AWS Resource Groups resource group named TestPowerShellGroup. The group includes Amazon EC2 instances in the current region that are tagged with the tag key "Name", and tag value "test2". The command returns the query and type of group, and the results of the operation.**  

```
$ResourceQuery = New-Object -TypeName Amazon.ResourceGroups.Model.ResourceQuery
$ResourceQuery.Type = "TAG_FILTERS_1_0"
$ResourceQuery.Query = '{"ResourceTypeFilters":["AWS::EC2::Instance"],"TagFilters":[{"Key":"Name","Values":["test2"]}]}'
$ResourceQuery

New-RGGroup -Name TestPowerShellGroup -ResourceQuery $ResourceQuery -Description "Test resource group."
```
**Output:**  

```
