Create an EC2 Instance Connect Endpoint - Amazon Elastic Compute Cloud

Create an EC2 Instance Connect Endpoint

You can create an EC2 Instance Connect Endpoint to allow secure connection to your instances.

Considerations

  • Shared subnets – You can create an EC2 Instance Connect Endpoint in a subnet shared with you. However, you can't use EC2 Instance Connect Endpoints that the VPC owner created in a subnet shared with you.

  • IP address types – EC2 Instance Connect Endpoints support the following address types, which must be compatible with your subnet:

    • ipv4 – Connect only to EC2 instances with private IPv4 addresses.

    • dualstack – Connect to EC2 instances with either private IPv4 addresses or IPv6 addresses.

    • ipv6 – Connect only to EC2 instances with IPv6 addresses.

Prerequisites

You must have the required IAM permissions to create an EC2 Instance Connect Endpoint. For more information, see Permissions to create, describe, modify, and delete EC2 Instance Connect Endpoints.

Console
To create an EC2 Instance Connect Endpoint

  1. Open the Amazon VPC console at https://console.aws.amazon.com/vpc/.

  2. In the left navigation pane, choose Endpoints.

  3. Choose Create endpoint, and then specify the endpoint settings as follows:

    1. (Optional) For Name tag, enter a name for the endpoint.

    2. For Type, choose EC2 Instance Connect Endpoint.

    3. Under Network settings, for VPC, select the VPC that has the target instances.

    4. (Optional) To preserve client IP addresses, expand Additional settings and select the Preserve Client IP check box. Otherwise, the default is to use the endpoint network interface as the client IP address.

      Note

      This option is only available when the endpoint's IP address type is configured as IPv4.

    5. (Optional) For Security groups, select the security group to associate with the endpoint. Otherwise, the default is to use the default security group for the VPC. For more information, see Security groups for EC2 Instance Connect Endpoint.

    6. For Subnet, select the subnet in which to create the endpoint.

    7. For IP address type, choose the IP address type for the endpoint. Choose Dualstack if you need to support both IPv4 and IPv6 connections to your instances. Choose IPv4 if you need to support client IP preservation.

    8. (Optional) To add a tag, choose Add new tag and enter the tag key and the tag value.

  4. Review your settings and then choose Create endpoint.

    The initial status of the endpoint is Pending. Before you can connect to an instance using this endpoint, you must wait until the endpoint status is Available. This can take a few minutes.

  5. To connect to an instance using your endpoint, see Connect to an instance.

AWS CLI
To create an EC2 Instance Connect Endpoint

Use the create-instance-connect-endpoint command.

aws ec2 create-instance-connect-endpoint \
    --subnet-id subnet-0123456789example

To specify the type of traffic that the endpoint supports, include the --ip-address-type parameter. Valid values are ipv4, dualstack, or ipv6. The subnet must support the IP address type that you specify. When the --ip-address-type parameter is omitted, the default value is determined by the IP address type supported by the subnet.

aws ec2 create-instance-connect-endpoint \
    --subnet-id subnet-0123456789example \
    --ip-address-type ipv4

The following is example output.

{
        "OwnerId": "111111111111",
        "InstanceConnectEndpointId": "eice-0123456789example",
        "InstanceConnectEndpointArn": "arn:aws:ec2:us-east-1:111111111111:instance-connect-endpoint/eice-0123456789example",
        "State": "create-complete",
        "StateMessage": "",

        "PreserveClientIp": false,
        "SecurityGroupIds": [

        ],
        "Tags": [],
        "IpAddressType": "ipv4"
}
To monitor the creation status

The initial value for the State field is create-in-progress. Before you can connect to an instance using this endpoint, wait until the state is create-complete. Use the describe-instance-connect-endpoints command to monitor the status of the EC2 Instance Connect Endpoint. The --query parameter filters the results to the State field.

aws ec2 describe-instance-connect-endpoints --instance-connect-endpoint-ids eice-0123456789example --query InstanceConnectEndpoints[*].State --output text

The following is example output.

create-complete
PowerShell
To create the EC2 Instance Connect Endpoint

Use the New-EC2InstanceConnectEndpoint cmdlet.

New-EC2InstanceConnectEndpoint -SubnetId subnet-0123456789example

To specify the type of traffic that the endpoint supports, include the -IpAddressType parameter. Valid values are ipv4, dualstack, or ipv6. The subnet must support the IP address type that you specify. When the -IpAddressType parameter is omitted, the default value is determined by the IP address type supported by the subnet.

New-EC2InstanceConnectEndpoint -SubnetId subnet-0123456789example -IpAddressType ipv4

The following is example output.

OwnerId                     : 111111111111
InstanceConnectEndpointId   : eice-0123456789example

To monitor the creation status

The initial value for the State field is create-in-progress. Before you can connect to an instance using this endpoint, wait until the state is create-complete. Use the Get-EC2InstanceConnectEndpoint cmdlet to monitor the status of the EC2 Instance Connect Endpoint. .State.Value filters the results to the State field.

(Get-EC2InstanceConnectEndpoint -InstanceConnectEndpointId "eice-0123456789example").State.Value

The following is example output.
