Synopsis

Invokes the AuthorizeSecurityGroupEgress operation against Amazon Elastic Compute Cloud.

Syntax

Grant-EC2SecurityGroupEgress
-GroupId <String>
-IpPermission <IpPermission[]>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

[EC2-VPC only] Adds one or more egress rules to a security group for use with a VPC. Specifically, this action permits instances to send traffic to one or more destination IPv4 or IPv6 CIDR address ranges, or to one or more destination security groups for the same VPC. This action doesn't apply to security groups for use in EC2-Classic. For more information, see Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide. For more information about security group limits, see Amazon VPC Limits. Each rule consists of the protocol (for example, TCP), plus either a CIDR range or a source group. For the TCP and UDP protocols, you must also specify the destination port or port range. For the ICMP protocol, you must also specify the ICMP type and code. You can use -1 for the type or code to mean all types or all codes. You can optionally specify a description for the rule. Rule changes are propagated to affected instances as quickly as possible. However, a small delay might occur.

Parameters

-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-GroupId <String>
The ID of the security group.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-IpPermission <IpPermission[]>
One or more sets of IP permissions. You can't specify a destination security group and a CIDR IP address range in the same set of permissions.
Required?False
Position?2
Accept pipeline input?False
-PassThru <SwitchParameter>
Returns the value passed to the GroupId parameter. By default, this cmdlet does not generate any output.
Required?False
Position?Named
Accept pipeline input?False

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String object to this cmdlet for the GroupId parameter.

Outputs

None or System.String
When you use the PassThru parameter, this cmdlet outputs the value supplied to the GroupId parameter. Otherwise, this cmdlet does not return any output. The service response (type Amazon.EC2.Model.AuthorizeSecurityGroupEgressResponse) can be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

PS C:\> $ip = @{ IpProtocol="tcp"; FromPort="80"; ToPort="80"; IpRanges="203.0.113.0/24" }

PS C:\> Grant-EC2SecurityGroupEgress -GroupId sg-12345678 -IpPermission $ip
This example defines an egress rule for the specified security group for EC2-VPC. The rule grants access to the specified IP address range on TCP port 80. The syntax used by this example requires PowerShell version 3 or higher.

Example 2

PS C:\> $ip = New-Object Amazon.EC2.Model.IpPermission
PS C:\> $ip.IpProtocol = "tcp"
PS C:\> $ip.FromPort = 80
PS C:\> $ip.ToPort = 80
PS C:\> $ip.IpRanges.Add("203.0.113.0/24")

PS C:\> Grant-EC2SecurityGroupEgress -GroupId sg-12345678 -IpPermission $ip
With PowerShell version 2, you must use New-Object to create the IpPermission object.

Example 3

PS C:\> $ug = New-Object Amazon.EC2.Model.UserIdGroupPair
PS C:\> $ug.GroupId = "sg-1a2b3c4d"
PS C:\> $ug.UserId = "123456789012"

PS C:\> Grant-EC2SecurityGroupEgress -GroupId sg-12345678 -IpPermission @( @{ IpProtocol="tcp"; FromPort="80"; ToPort="80"; UserIdGroupPairs=$ug } )
This example grants access to the specified source security group on TCP port 80.
