# Configuring interface VPC endpoints (AWS PrivateLink) for AWS Glue (AWS PrivateLink)
Configuring interface VPC endpoints (AWS PrivateLink) for AWS Glue

You can establish a private connection between your VPC and AWS Glue by creating an *interface VPC endpoint*. Interface endpoints are powered by [AWS PrivateLink](https://aws.amazon.com/privatelink), a technology that enables you to privately access AWS Glue APIs without an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Instances in your VPC don't need public IP addresses to communicate with AWS Glue APIs. Traffic between your VPC and AWS Glue does not leave the Amazon network. 

Each interface endpoint is represented by one or more [Elastic Network Interfaces](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html) in your subnets. 

For more information, see [Interface VPC endpoints (AWS PrivateLink)](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html) in the *Amazon VPC User Guide*. 

## Considerations for AWS Glue VPC endpoints


Before you set up an interface VPC endpoint for AWS Glue, ensure that you review [Interface endpoint properties and limitations](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#vpce-interface-limitations) in the *Amazon VPC User Guide*. 

AWS Glue supports making calls to all of its API actions from your VPC. 

## Creating an interface VPC endpoint for AWS Glue


You can create a VPC endpoint for the AWS Glue service using either the Amazon VPC console or the AWS Command Line Interface (AWS CLI). For more information, see [Creating an interface endpoint](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#create-interface-endpoint) in the *Amazon VPC User Guide*.

Create a VPC endpoint for AWS Glue using the following service name: 
+ com.amazonaws.*region*.glue

If you enable private DNS for the endpoint, you can make API requests to AWS Glue using its default DNS name for the Region, for example, `glue.us-east-1.amazonaws.com`. 

For more information, see [Accessing a service through an interface endpoint](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#access-service-though-endpoint) in the *Amazon VPC User Guide*.

## Creating a VPC endpoint policy for AWS Glue


You can attach an endpoint policy to your VPC endpoint that controls access to AWS Glue. The policy specifies the following information:
+ The principal that can perform actions.
+ The actions that can be performed.
+ The resources on which actions can be performed.

For more information, see [Controlling access to services with VPC endpoints](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-endpoints-access.html) in the *Amazon VPC User Guide*. 

**Example: VPC endpoint policy for AWS Glue to allow job creation and update**  
The following is an example of an endpoint policy for AWS Glue. When attached to an endpoint, this policy grants access to the listed AWS Glue actions for all principals on all resources.

```
{
  "Statement": [
    {
      "Sid": "RestrictPassRole",
      "Effect": "Allow",
      "Action": "iam:PassRole",
      "Resource": "arn:aws:iam::123456789012:role/GlueServiceRole*",
      "Condition": {
        "StringEquals": {
          "iam:PassedToService": "glue.amazonaws.com"
        }
      }
    }
  ]
}
```

**Example: VPC endpoint policy to allow read-only Data Catalog access**  
The following is an example of an endpoint policy for AWS Glue. When attached to an endpoint, this policy grants access to the listed AWS Glue actions for all principals on all resources.

```
{
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "glue:GetDatabase",
        "glue:GetDatabases",
        "glue:GetTable",
        "glue:GetTables",
        "glue:GetTableVersion",
        "glue:GetTableVersions",
        "glue:GetPartition",
        "glue:GetPartitions",
        "glue:BatchGetPartition",
        "glue:SearchTables"
      ],
      "Resource": "*"
    }
  ]
}
```
