Use DescribeVpcEndpoints with a CLI

To describe your VPC endpoints

The following describe-vpc-endpoints example displays details for all of your VPC endpoints.

aws ec2 describe-vpc-endpoints

Output:

Example 1: This example describes one or more of your VPC endpoints for the region eu-west-1. It then pipes the output to the next command, which select the VpcEndpointId property and returns array VPC ID as string array

Get-EC2VpcEndpoint -Region eu-west-1 | Select-Object -ExpandProperty VpcEndpointId

Output:

vpce-01a2ab3f4f5cc6f7d
vpce-01d2b345a6787890b
vpce-0012e34d567890e12
vpce-0c123db4567890123

Example 2: This example describes all the vpc endpoints for the region eu-west-1 and selects VpcEndpointId, VpcId, ServiceName and PrivateDnsEnabled properties to present it in a tabular format

Get-EC2VpcEndpoint -Region eu-west-1 | Select-Object VpcEndpointId, VpcId, ServiceName, PrivateDnsEnabled | Format-Table -AutoSize

Output:

VpcEndpointId          VpcId                 ServiceName                         PrivateDnsEnabled

Example 3: This example exports the policy document for the VPC Endpoint vpce-01a2ab3f4f5cc6f7d into a json file

Get-EC2VpcEndpoint -Region eu-west-1 -VpcEndpointId vpce-01a2ab3f4f5cc6f7d | Select-Object -expand PolicyDocument | Out-File vpce_policyDocument.json
