Auto Attachment of your EC2

Your EC2 can automatically be attached to a default Route53 Private Hosted Zone (PHZ) called dns53.

dns53 --auto-attach

For this to work as intended, dns53 handles two attachment scenarios, removing the need for any PHZ management. 👍

You are the first Auto Attachment

Congratulations, you beat everyone else in your team or organisation and auto-attached your EC2 to the default dns53 PHZ. dns53 will:

1. Create the new dns53 PHZ and associate the launched EC2 VPC with it.
2. Broadcasts your EC2 as expected, using a custom domain name if provided.
3. Tidies everything up when you exit.

Auto Attachment has already happened

If someone in your team, or organisation, was super keen and already auto-attached their EC2 to the default dns53 PHZ, your attachment will be slightly different. dns53 will:

1. Check if your launched EC2 is within a VPC associated with the PHZ. If not, it will create a new association.
2. Broadcasts your EC2 as expected, using a custom domain name if provided.
3. Tidies everything up when you exit.
