attach-classic-link-vpc¶
Description¶
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.

Synopsis¶
attach-classic-link-vpc
[--dry-run | --no-dry-run]
--groups <value>
--instance-id <value>
--vpc-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
Options¶
--dry-run | --no-dry-run (boolean)
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is
DryRunOperation. Otherwise, it isUnauthorizedOperation.
--groups (list)
The ID of one or more of the VPC’s security groups. You cannot specify security groups from a different VPC.
(string)
Syntax:
"string" "string" ...
--instance-id (string)
The ID of an EC2-Classic instance to link to the ClassicLink-enabled VPC.
--vpc-id (string)
The ID of a ClassicLink-enabled VPC.
--cli-input-json | --cli-input-yaml (string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.
--generate-cli-skeleton (string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
