attach_classic_link_vpc

EC2.Client.attach_classic_link_vpc(**kwargs)

Note

We are retiring EC2-Classic. We recommend that you migrate from EC2-Classic to a VPC. For more information, see Migrate from EC2-Classic to a VPC in the Amazon Elastic Compute Cloud User Guide.

Links an EC2-Classic instance to a ClassicLink-enabled VPC through one or more of the VPC’s security groups. You cannot link an EC2-Classic instance to more than one VPC at a time. You can only link an instance that’s in the running state. An instance is automatically unlinked from a VPC when it’s stopped - you can link it to the VPC again when you restart it.

After you’ve linked an instance, you cannot change the VPC security groups that are associated with it. To change the security groups, you must first unlink the instance, and then link it again.

Linking your instance to a VPC is sometimes referred to as attaching your instance.
