# NodegroupRemoteAccess

The remote access (SSH) configuration to use with your node group.

- Source: [`aws-eks/lib/managed-nodegroup.ts`](https://github.com/aws/aws-cdk/blob/v2.274.0/packages/aws-cdk-lib/aws-eks/lib/managed-nodegroup.ts#L138)

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_ec2 as ec2 } from 'aws-cdk-lib';
import { aws_eks as eks } from 'aws-cdk-lib';

declare const securityGroup: ec2.SecurityGroup;
const nodegroupRemoteAccess: eks.NodegroupRemoteAccess = {
  sshKeyName: 'sshKeyName',

  // the properties below are optional
  sourceSecurityGroups: [securityGroup],
};
```

## Properties

- `sourceSecurityGroups`: [ISecurityGroup](/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.ISecurityGroup.html)[] — The security groups that are allowed SSH access (port 22) to the worker nodes.

  **Default:** port 22 on the worker nodes is opened to the internet (0.0.0.0/0)

  If you specify an Amazon EC2 SSH
  key but do not specify a source security group when you create a managed node group, then port 22 on the worker
  nodes is opened to the internet (0.0.0.0/0).

- `sshKeyName`: string (required) — The Amazon EC2 SSH key that provides access for SSH communication with the worker nodes in the managed node group.
