Aws Transfer family - Vpc hosted

Question

Hi,

Under Vpc hosted category i want to choose internet-facing using cloud formation template.

I have yaml file for internal but can't code for internet-facing.

Accepted Answer

Hello Mahendra Kumar V,

To create Internet Facing VPC type servers, you have to provide `Elastic-IPs` or `AddressAllocation-IDs` when you are creating the server. Within your template, I see that is missing which is why Transfer service is creating an Internal VPC type server. Following is an example template: 
```
AWSTemplateFormatVersion: 2010-09-09
Resources:
  SFTPServer:
    Type: 'AWS::Transfer::Server'
    Properties:
      EndpointType: 'VPC'
      EndpointDetails:
        VpcId: ''
        SubnetIds: 
          - ''
        AddressAllocationIds:
          - ''
      LoggingRole: ''

Note: You have to provide the Allocation ID for the Elastic IP and not the IP itself. Allocation Ids look like this - eipalloc-0fb1a029axxxxxx
```

The above should help you in creating Internet-Facing VPC type servers.

Do let us know if you have further questions.

Answer

You can use the following example YAML code as a starting point:

yaml
```
Resources:
  TransferServer:
    Type: AWS::Transfer::Server
    Properties:
      EndpointType: PUBLIC
      IdentityProviderType: SERVICE_MANAGED
      LoggingRole: 
      ProtocolDetails:
        PassivePorts: "30000-30009"
      SecurityPolicyName: TLS_1_2
      Tags:
        - Key: Name
          Value: my-transfer-server
      VpcId: 
      EndpointDetails:
        VpcEndpointId: 
        SubnetIds:
          - 
          - 
        SecurityGroupIds:
          -

Outputs:
  TransferServerArn:
    Value: !GetAtt TransferServer.Arn
    Export:
      Name: MyTransferServerArn
```

Note that you will need to replace the placeholder values (, , , , , and ) with actual values that are relevant to your setup.

Hai,

I was tried with this yaml file, That was cretaed transfer family server witth Internal access.

Custom hostname
